Throwable Asset Reference

Intermediate40-60 minutesWindowsUnity EditorBlenderNotepad++

Throwable items are the most deceptively complex item category in Unturned™ modding. A grenade looks straightforward — the player presses a button, the item arcs through the air, and something happens when it lands. But the .dat field set behind that sequence is extensive, and the failure modes are not always traceable to a single root cause. A frag grenade that does no damage, a smoke grenade that produces fire, a flashbang that detonates as a frag, a molotov that ignites instantly at the player's feet — all are common outcomes of misconfigured throwable .dat files.

This article is the 57 Studios™ cohort reference for throwable asset authoring. It covers every throwable sub-type, every per-type .dat field, fuse timing and cook mechanics, throw arc physics, explosion effect linkage, damage falloff math, underbarrel-launched throwables, and the complete table of common pitfalls with their fixes.

Throwable sub-types

Unturned™ throwables are all authored with Type Throwable in the .dat, but they differentiate by the combination of effect fields present. The engine reads the effect fields at load time and infers the throwable's behavior. There is no separate Sub_Type field; behavior is determined entirely from field presence and values.

Informal sub-type	Behavior	Key distinguishing fields
Frag grenade	Explosion on detonate; damages players, zombies, structures	Explosive true, Range > 0, Damage_* fields, Explosion effect ID
Smoke grenade	Deploys a smoke particle cloud	Explosive false, Smoke_Explosion effect ID, Smoke_Duration
Flashbang	Blinds and deafens players in range	Explosive false, Flash_Range, Flash_Duration, Flash_Explosion
Molotov	Creates a fire zone on impact	Explosive true, Impact true, Explosion referencing fire effect
Sticky explosive	Adheres to surfaces or vehicles before detonating	Sticky true, Explosive true
Launcher-deployed	Fired from underbarrel launcher attachment on a gun	Explosive true, Impact true, very short Fuse; paired with gun magazine

All of these use Type Throwable in the .dat. The distinction is purely in the effect and behavior fields.

Sub-type is inferred, not declared

There is no Sub_Type or Grenade_Type field. The engine builds behavior from the fields that are present. A throwable with both Smoke_Explosion and Explosive true produces both smoke and an explosion — it is neither a pure smoke grenade nor a pure frag grenade. This composability is intentional and enables specialty throwable designs.

Core .dat fields common to all throwables

Every throwable item requires the standard item identity fields plus the fields in this section.

Field	Type	Example	Purpose
ID	uint16	5001	Unique item ID. Use IDs above 50000 for community mods to avoid collision.
GUID	uint128	c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8	Globally unique identifier. Generate a fresh GUID for every new throwable.
Type	enum	Throwable	Declares this item as a throwable. Required.
Name	string	MyGrenade	Internal name. Used in console commands and mod cross-references.
Rarity	enum	Uncommon	Item rarity: Common, Uncommon, Rare, Epic, Legendary, Mythical.
Size_X / Size_Y	uint8	1 / 1	Inventory footprint. Most grenades are 1×1.
Fuse	float	3.0	Fuse duration in seconds from the moment of throw to detonation.
Explosive	bool	true	When true, the item produces an explosion on detonation. Required for frag and molotov.
Range	float	10.0	Explosion radius in meters. Determines which entities within this radius take damage.
Explosion	uint16	20	The effect asset ID that plays on detonation. Controls the visual and audio explosion.
Spawn_Explosion	bool	false	When true, the explosion effect is spawned even if no entities are within damage range.
Impact	bool	false	When true, the throwable detonates on first contact with any surface, overriding the fuse.
Sticky	bool	false	When true, the throwable adheres to the first surface or vehicle it contacts.

---

Fuse timing and cook mechanics

The Fuse field controls how many seconds elapse between throw and detonation. The default Unturned™ frag grenade has a 3-second fuse. The engine begins the fuse countdown when the player releases the throw input, not when the player presses the button.

Cook mechanics

Unturned™ supports grenade cooking — the player holds the grenade after pressing the throw button, reducing the fuse duration before the grenade leaves the hand. The cook window is the period between pressing the throw button and releasing it.

Cook time math

Detonation time after throw = Fuse − time spent cooking. If the player cooks for 2.8 seconds on a 3-second fuse grenade and then throws, the grenade detonates 0.2 seconds after throw. Cooking all the way to zero causes the grenade to detonate in the player's hand. There is no Max_Cook or cook-lock field; cooking behavior is entirely driven by the Fuse value and player input timing.

Fuse value reference

Fuse value	Behavior
0.0	Detonates instantly on throw or on Impact true contact
0.5	Very short fuse — detonates before most players can move clear
2.0	Short fuse — pressure-based play; limited cook window
3.0	Standard fuse — vanilla default; allows repositioning after throw
5.0	Long fuse — defenders can potentially pick up and throw back
10.0+	Very long fuse — used for timed explosives and trip-wire devices

Contact vs timed detonation

Setting Impact true makes the throwable detonate the moment it contacts any surface — wall, floor, vehicle, or player. The Fuse value becomes a maximum timer in this case: the throwable detonates on contact OR when the fuse expires, whichever comes first. Setting Impact true with a long Fuse produces a contact grenade that still detonates if it lands softly on a surface that does not register a hard contact event.

---

Throw arc and physics

Unturned™ throwables follow a projectile arc governed by the engine's physics system. Modders do not directly control arc trajectory in the .dat; the arc is a function of the player's look angle and the throwable's mass. The throwable mesh assigned to the prefab does have a Unity Rigidbody component, and the physics material on the prefab's collider controls bounce behavior.

What you control in the .dat is what happens at the detonation point. The trajectory itself is physics-driven. To tune bounce behavior, modify the physics material on the throwable's Unity prefab (not the .dat).

---

Frag grenade fields

A frag grenade causes an explosive burst that damages entities within Range meters of the detonation point.

Field	Type	Example	Purpose
Explosive	bool	true	Must be true for frag grenades.
Damage_Player	float	200	Damage to a player at the explosion center. Scales with distance via falloff.
Damage_Zombie	float	300	Damage to a zombie at the explosion center.
Damage_Animal	float	200	Damage to an animal at the explosion center.
Damage_Barricade	float	200	Damage to a barricade at the explosion center.
Damage_Structure	float	100	Damage to a structure at the explosion center.
Damage_Vehicle	float	300	Damage to a vehicle at the explosion center.
Damage_Resource	float	200	Damage to a resource node at the explosion center.
Damage_Object	float	200	Damage to a map object at the explosion center.
Range	float	10.0	Full blast radius in meters.
Range_Vehicle	float	10.0	Blast radius for vehicle damage specifically. Can be set independently of Range.
Range_Resource	float	10.0	Blast radius for resource damage specifically.
Range_Object	float	10.0	Blast radius for object damage specifically.
Explosion	uint16	20	Effect asset ID for the explosion visual and audio.

Damage falloff with distance

Explosion damage is not flat across the blast radius. It falls off linearly from the center to the edge of Range:

Damage at distance d = Damage_* × max(0, 1 - d / Range)

Distance from center	Fraction of full damage
0 m (direct hit)	100%
Range / 4	75%
Range / 2	50%
Range × 3/4	25%
Range (edge)	0%

Design around the falloff curve

Design grenades around this curve. If you want a grenade that reliably kills a full-health player (200 HP) within 5 meters, set Damage_Player high enough that 75% of the value exceeds 200. With Damage_Player 300, a player at 5 meters of a 10-meter radius grenade takes 300 × (1 - 5/10) = 150 — not a kill. Increase Damage_Player to 450 for a reliable kill at 5 meters, or reduce Range to 8 so 5 meters is within the 60% falloff zone.

Smoke grenade fields

Smoke grenades deploy a particle cloud that obscures vision for players in the area. They do not deal damage; their purpose is area denial, covering movement, or signaling.

Field	Type	Example	Purpose
Explosive	bool	false	Must be false for smoke grenades.
Smoke_Explosion	uint16	32	Effect asset ID for the smoke cloud particle system.
Smoke_Duration	float	30.0	Duration in seconds the smoke effect persists after detonation.
Smoke_Range	float	10.0	Radius of the smoke cloud effect at the detonation point.

Smoke color is in the effect asset

The color of the smoke is defined in the effect asset referenced by Smoke_Explosion, not in the throwable .dat. To produce a colored smoke grenade (red, green, yellow for signal purposes), author a custom effect asset with the desired particle color and reference it via Smoke_Explosion. The throwable .dat only controls duration and radius.

Example smoke grenade .dat

Rarity Common
Size_X 1
Size_Y 1

Fuse 2.0
Explosive false
Smoke_Explosion 32
Smoke_Duration 30.0
Smoke_Range 10.0

---

Flashbang fields

Flashbangs temporarily blind and deafen players within range. They do not deal damage. The blind effect simulates camera whiteout; the deaf effect suppresses in-game audio for the duration.

Field	Type	Example	Purpose
Explosive	bool	false	Must be false for flashbangs.
Flash_Explosion	uint16	45	Effect asset ID for the flash burst visual.
Flash_Range	float	15.0	Radius within which players are blinded and deafened.
Flash_Duration	float	5.0	Duration in seconds of the blind and deaf effect.

Explosive field on flashbangs is the most common error

Setting Explosive true on a flashbang converts it into a frag grenade that also produces a flash. The engine does not warn about this combination. Confirm Explosive false for all smoke grenades and flashbangs before testing.

Flashbang effect on NPCs and zombies

The flash effect in vanilla Unturned™ affects only players within Flash_Range. Zombies and animals are not blinded. Custom NPC behavior via server plugins may change this, but standard .dat flashbangs have no effect on non-player entities.

Example flashbang .dat

Fuse 2.5

Flash_Explosion 45
Flash_Range 15.0
Flash_Duration 5.0

---

Molotov fields

A molotov is a throwable that creates a fire zone on impact. The fire damages entities that enter or remain in the zone over time. The fire zone is implemented as an effect asset that includes a damage-over-time area component.

Field	Type	Example	Purpose
Explosive	bool	true	Set true for molotov; the detonation event spawns the fire effect.
Explosion	uint16	18	Effect asset ID for the fire zone. The referenced effect must include a damage-over-time component.
Range	float	5.0	Radius of the fire zone at the detonation point.
Impact	bool	true	Most molotovs detonate on first surface contact rather than on a timed fuse.
Fuse	float	5.0	If Impact false, the fuse controls detonation timing. Set to a high value for drop-and-detonate behavior.

Fire zone duration is in the effect asset

The duration of the fire zone is controlled by the effect asset's particle system lifetime, not by a throwable .dat field. To produce a fire zone that lasts 20 seconds, author an effect asset with a 20-second particle system lifetime and reference it via Explosion. The throwable .dat only determines the zone radius through Range.

Example molotov .dat

Sticky throwable fields

Sticky throwables adhere to surfaces or vehicles upon contact, then detonate after the fuse expires. They are used for anti-vehicle charges, timed demolition devices, and specialty gameplay items in RP scenarios.

Field	Type	Example	Purpose
Sticky	bool	true	When true, the throwable adheres to the first surface it contacts instead of bouncing.
Fuse	float	5.0	Time in seconds from adhesion to detonation.
Explosive	bool	true	Sticky explosives are typically frag-type. Set all Damage_* and Explosion fields.
Range	float	8.0	Blast radius of the sticky explosive after detonation.
Range_Vehicle	float	12.0	Vehicle-specific blast radius. Set higher than Range for anti-vehicle charges.

Sticky and vehicle interaction

Sticky throwables that adhere to vehicles move with the vehicle until detonation. This makes them particularly effective for anti-vehicle gameplay because the explosive cannot be driven away from.

Sticky adheres to the first surface contact

If the sticky throwable contacts a wall or floor before reaching the intended vehicle, it adheres to that surface instead. The Sticky flag does not discriminate between surfaces; it adheres to the first surface contact in all cases.

Example sticky explosive .dat

Launcher-deployed throwable fields

Some throwable items are designed to be launched from an underbarrel launcher attachment on a gun rather than thrown by hand. These are still Type Throwable in their .dat, but they are paired with a gun's magazine system via the magazine .dat's projectile field.

Field	Type	Recommended value	Purpose
Explosive	bool	true	Launcher grenades are frag-type.
Range	float	6.0	Blast radius. Typically smaller than hand grenades — shorter arming range.
Impact	bool	true	Launcher grenades detonate on surface contact, not on a timed fuse.
Fuse	float	0.1	Very short fuse ensures detonation after brief flight time even without impact contact.
Damage_Player	float	150	Lower than a hand grenade; launcher grenades compensate with precision, not power.

Pairing to the gun

The linkage between a launcher grenade and a gun is made in the gun's magazine .dat by referencing the throwable item's GUID as the projectile type. The throwable .dat does not declare its own launcher compatibility; the gun's magazine declares what it launches. See the Gun Mod Tutorial for the magazine configuration that enables launcher-deployed throwables.

Effect linkage: the Explosion field

The Explosion field on a throwable references an effect asset that plays at the detonation point. The field accepts the effect asset's uint16 ID. The effect asset must be bundled in the same master bundle as the throwable, or it must be a vanilla effect ID.

Common vanilla effect IDs

Effect ID	Description	Use case
18	Fire explosion and zone	Molotov, incendiary grenade
20	Standard frag explosion	Frag grenade, rocket impact
32	White smoke cloud	Smoke grenade
45	Flash burst	Flashbang

Custom effect assets require bundling

Custom effect assets must be authored in Unity as effect prefabs, assigned to the master bundle, and referenced by their ID in the throwable .dat. If the effect asset is not in the master bundle at the correct ID, the detonation produces no visual — the damage still occurs, but the player sees nothing. Always test the visual effect in single-player before publishing. Use IDs above 50000 for custom effects to avoid collision with vanilla effect IDs.

Spawn_Explosion for guaranteed visual

Set Spawn_Explosion true when you want the explosion effect to spawn even if no entities are in range to receive damage. This is useful for smoke and signal grenades where the visual effect is the primary purpose regardless of whether any entities are nearby.

Common pitfalls and their fixes

Symptom	Root cause	Fix
Grenade does no damage	Explosive false on a frag grenade	Set Explosive true
Grenade detonates instantly on throw	Fuse 0.0 without Impact true intended	Set Fuse to desired countdown duration
Flashbang creates an explosion and kills players	Explosive true on a flashbang	Set Explosive false; confirm no Damage_* fields present
Smoke grenade produces fire	Explosion references a fire effect ID	Change Smoke_Explosion to the correct smoke effect asset ID
No visual effect on detonation	Explosion 0 or effect asset not in bundle	Set Explosion to a valid effect ID; confirm effect is bundled
Damage too high at maximum range	Range too large relative to Damage_* values	Reduce Range or reduce Damage_*; account for the linear falloff curve
Damage too low near the center	Damage_* values too conservative	Increase Damage_* values; use the falloff formula to verify expected values at each distance
Sticky grenade does not adhere	Sticky false	Set Sticky true
Sticky grenade adheres to wrong surface	Player threw toward vehicle but hit a wall first	Sticky adheres to the first contact — aim accordingly; no .dat fix available
Fuse never expires	Fuse set to an extremely large value by mistake	Set Fuse to the intended countdown duration
Grenade detonates in thrower's hand	Player cooked the fuse all the way to zero	Increase Fuse or document the cook risk in the English.dat description
Launcher grenade does not spawn from the gun	Launcher round not paired to the gun's magazine .dat	Author the magazine .dat referencing the throwable GUID as the projectile type
Smoke cloud disappears too quickly	Smoke_Duration too low	Increase Smoke_Duration (30 seconds is a usable minimum)
Flashbang blind radius too wide	Flash_Range too large	Reduce Flash_Range to 10–15 meters for standard balance
Molotov fire zone too small	Range too low	Increase Range for the fire effect radius
Grenade bounces unpredictably	Physics material on prefab is too bouncy	Replace the physics material on the throwable prefab with a less elastic material in Unity

How-to: author a custom frag grenade from scratch

Step-by-step summary:

1. Model and texture the grenade mesh in Blender. A 1024×1024 albedo is sufficient for a small 1×1 item — grenades are rarely examined closely in-game.
2. Export the FBX and import to Unity. The throwable prefab is minimal compared to a weapon — no animation rig is required. Add a Rigidbody and a BoxCollider or SphereCollider for physics interaction.
3. Author or reference an explosion effect asset. For a first grenade, use a vanilla effect ID (20 for standard frag) before investing time in a custom effect.
4. Bundle the prefab (and custom effect, if used) together with the same asset bundle name.
5. Author the .dat with Type Throwable, Explosive true, Fuse, Range, and all Damage_* fields.
6. Author English.dat with a display name and description. Include the blast radius in the description so players can evaluate the item's gameplay role.
7. Test in single-player: spawn the grenade with @give, throw it, and verify detonation, damage, and visual effect. Use the falloff formula to verify damage at multiple distances.

Balance reference table

The table below documents selected vanilla Unturned™ throwable values for calibration purposes.

Item (vanilla reference)	Fuse	Range	Damage_Player	Notes
Military Frag Grenade	3.0	10.0	200	Standard frag; kills within ~7m
Flashbang	2.5	15.0	0	Flash only; wide range
Smoke Grenade	2.0	10.0	0	Smoke only; 30-second duration
Molotov	—	5.0	0 (DoT via fire)	Impact detonation; fire effect duration is in effect asset
Sticky Grenade	5.0	8.0	150	Anti-vehicle focus

Calibrate against vanilla

Start from the vanilla values nearest to your intended throwable role and adjust one field at a time. Changing both Damage_Player and Range simultaneously makes it difficult to identify which change is causing a balance issue. Adjust Range first to set the blast footprint, then tune Damage_* to achieve the intended lethality curve.

Frequently asked questions

Why does my grenade damage me when I throw it?

The grenade detonated before reaching sufficient distance from the thrower. Either Fuse is too short (the player cannot move away before detonation), Range is too large (the blast reaches the throw point), or the player cooked the fuse close to zero. Increase Fuse or reduce Range. As a safety minimum, Range should not exceed the distance a player can travel in Fuse seconds.

Can I make a grenade that deals different damage to different entity types?

Yes. The Damage_Player, Damage_Zombie, Damage_Animal, Damage_Barricade, Damage_Structure, Damage_Vehicle, Damage_Resource, and Damage_Object fields are fully independent. For an anti-structure charge, set Damage_Structure and Damage_Barricade high while keeping Damage_Player lower. For an anti-vehicle charge, set Damage_Vehicle high and use Range_Vehicle for the vehicle-specific blast radius.

How do I make a grenade that detonates on contact?

Set Impact true and Fuse 0.0 (or a very short value like 0.1 as a failsafe). The grenade detonates the moment it contacts any surface. This configuration is standard for molotovs and launcher-deployed grenades.

Why does my smoke grenade deal damage?

The smoke effect asset referenced by Smoke_Explosion may include a damage zone — some vanilla effect assets do. Use the vanilla smoke effect ID (32) or author a custom effect prefab without a damage component. Also confirm Explosive false is set on the throwable .dat.

Can I have a grenade with both smoke and an explosion?

Yes. Set Explosive true with Damage_* and Explosion fields, and also set Smoke_Explosion and Smoke_Duration. The detonation produces both the explosion and the smoke cloud simultaneously. This is the incendiary grenade pattern — useful for area-denial combined with direct damage.

What is the maximum blast radius for a frag grenade?

There is no engine-enforced maximum. In practice, blast radii above 15–20 meters make grenades nearly unavoidable and break competitive server balance. The 57 Studios™ cohort recommendation is to stay at or below 12 meters for a standard frag grenade intended for public use. Document the blast radius in the Workshop description.

How do I make a grenade that the player cannot cook?

Unturned™ does not expose a "no cook" flag. The closest approximation is to use Impact true — the grenade detonates on first surface contact after throw, so the player cannot hold it in the air. For very short fuses, the practical cook window is too small to be useful regardless.

Can a flashbang affect zombies or animals?

The flash effect in vanilla Unturned™ affects only players within Flash_Range. Zombies and animals are not blinded or deafened. Server-side plugins may extend this behavior, but the standard .dat flashbang affects players only.

Why does the explosion effect spawn at the wrong position?

The effect spawns at the grenade's world position at the moment of detonation. If the grenade has partially embedded into terrain (common with fast or heavy projectiles), the effect may appear slightly below the surface. The throwable .dat does not have a spawn offset field; compensate by adjusting the effect asset's particle system origin offset in Unity.

How do I reference a custom explosion effect?

Author the explosion effect in Unity as an effect prefab, assign it to the master bundle, and give it a unique ID in its own .dat file. Reference that ID in the throwable's Explosion field. Custom effect IDs must not collide with vanilla IDs — use IDs above 50000 for custom effects.

Can I make a grenade that bounces multiple times before detonating?

The bounce count is physics-driven and depends on the throwable prefab's physics material in Unity. A more elastic physics material produces more bounces before the grenade comes to rest. The .dat does not have a bounce count field. Set Impact false and use a high Fuse value to allow the grenade to bounce to its rest position before detonating.

What happens if Fuse is set to a negative value?

A negative Fuse value causes the throwable to detonate immediately when thrown, before it leaves the player's hand. This is equivalent to Fuse 0.0. Do not use negative values.

Can the same throwable serve as both a hand grenade and a launcher round?

The same throwable item GUID can be referenced both by a player throwing it by hand and by a gun launcher's magazine .dat. The .dat does not need modification; the launcher magazine references the throwable GUID as its projectile type. Balance the throwable for both use cases, since the same item will function identically in both delivery contexts.

Appendix C: damage falloff worked examples

Scenario	Damage_Player	Range	Damage at 0 m	Damage at 5 m	Damage at 10 m	Lethality (200 HP player)
Light grenade	100	10.0	100	50	0	No kill at any range
Standard grenade	200	10.0	200	100	0	Kill within ~0 m; wound to 7 m
Heavy grenade	300	10.0	300	150	0	Kill within ~3.3 m
Anti-personnel	400	12.0	400	233	67	Kill within ~6 m
Concussive (non-lethal)	80	8.0	80	40	0	No kill at any range
Anti-vehicle focus	150	10.0	150	75	0	Wound only; vehicle gets Damage_Vehicle

To calculate the kill radius for a given Damage_Player and player HP:

Kill radius = Range × (1 - PlayerHP / Damage_Player)

For Damage_Player 300, Range 10, PlayerHP 200:

Kill radius = 10 × (1 - 200/300) = 10 × 0.333 = 3.33 meters
