By default, it contains
item_dynamic_resupply, an entity that spawns whatever item the player needs most (health, armor, ammo). By changing the crate's Item Type, you can make it drop specific items.
In code, it is represented by class
CItem_ItemCrate, defined in
item_itemcrate.cpp. (This is not a

Crate Contains (CrateType)
- Deprecated. Do not alter. Numbers other than 0 will cause the crate to spawn nothing after being broken. (If that's desired, try to use a
prop_physicsinstead as it's not as memory-intensive.)
- Item Type (ItemClass)
- Classname of the entity to spawn when the crate is broken. Suggested point entity:
- Item Count (ItemCount)
- Number of items to drop upon breakage.

- Mass Scale (massscale)
- Multiplier for the object's mass.
- Override Parameters (overridescript)
- A list of physics keyvalues that are usually embedded in the model. Format is
- Health Level to Override Motion (damagetoenablemotion)
- If specified, this object will start with motion disabled. Once its health has dropped below this specified amount, it will enable motion.
- Physics Impact Force to Override Motion (forcetoenablemotion)
- If specified, this object will start motion disabled. Any impact that imparts a force greater than this value will enable motion.
- Minimum DX Level (mindxlevel)
- Maximum DX Level (maxdxlevel)
- The entity will not exist if the engine is running outside the given range of DirectX Versions. Only used by Orange Box and 2013 SDK games.
- Warning: If these are used, the object may break when the user switches their DirectX settings.
- Default (no bounding)
- DX9 SM2
- DX9 SM3
- World Model (model)
- The model this entity should appear as. 128-character limit.
- Skin (skin or ModelSkin )
- Some models have multiple skins. This value selects from the index, starting with 0.

- Method of collision for this entity.
- Body Group (body or SetBodyGroup)
- Sets the the active $bodygroup.
- Hitbox Set (hitboxset)
- Sets the $hboxset to use.

- Damage Filter Name (damagefilter)
- When this entity receives damage, it will filter by this entity.
- Start Fade Distance (fademindist)
- Distance at which the entity starts fading. If <0, the entity will disappear instantly when end fade is hit. The value will scale appropriately if the entity is in a 3D Skybox.
- End Fade Distance (fademaxdist)
- Distance at which the entity ends fading. If <0, the entity won't disappear at all. The value will scale appropriately if the entity is in a 3D Skybox.
- Fade Scale (fadescale)
- If specified in the
worldspawn, or if the engine is running below DirectX 8, entities will fade out even if the fade distances above aren't specified. This value gives more control over when this happens: numbers smaller than 1 cause the entity to fade out at further distances, and greater than 1 cause it to fade out at closer distances. Using 0 turns off the forced fade altogether. See also
- Render Mode (rendermode)
- Set a non-standard rendering mode on this entity.

AddOutput, which will influence how the engine deals with the entity in certain circumstances.
- Name (targetname)
- The name that other entities refer to this entity by.
- Global Entity Name (globalname)
- Name by which this entity is linked to another entity in a different map. When the player transitions to a new map, entities in the new map with globalnames matching entities in the previous map will have the previous map's state copied over their state.
- Parent (parentname)
- Specifies a movement parent. An entity will maintain its initial offset from its parent. An attachment point can be added to the end of the name, separated by a comma. Every entity can be parented, even point entities. Entities which are parented will be forced to transition to the next map, such as from a
trigger_transition. Some entities which aren't intended to be parented may not function correctly.
phys_constraintcan be used as a workaround to parenting.
- Origin (X Y Z) (origin)
- The position of this entity's center in the world. Rotating entities typically rotate around their origin.
- Pitch Yaw Roll (X Y Z) (angles)

- The local time of the entity, independent of the global clock. Used mainly for physics calculations.
- Next Think (nextthink)
- Amount of time before the entity thinks again.
- Hammer ID (hammerid)
- The entity's Hammer ID. Mainly used by plugins and debugging commands, such as
ent_keyvalue. Can be manually assigned with the "hammerid" or "id" keyvalue. Entities spawned at run-time are not assigned any Hammer ID.
- Tell the prop to quit moving. Any physics forces (excluding gravity and water buoyancy) will cause the object to resume moving as usual. Sleeping also occurs automatically when the object has no physics forces to keep it awake, and when it is no longer moving a noticeable amount.
- If the object was told to sleep, tell it to start moving again.
- Tell the object to stop moving completely. No physics forces will re-enable motion, not even
- If the object's motion has been disabled entirely, tell it to resume movement as usual. This will also
Wakethe object, if it is

- Sets the entity's lighting origin to use this entity's position.
- Offsets the entity's lighting origin by their distance from an
- Sets distance at which the entity starts fading. If <0, the entity will disappear instantly when end fade is hit. The value will scale appropriately if the entity is in a 3D Skybox.
- Sets distance at which the entity ends fading. If <0, the entity won't disappear at all. The value will scale appropriately if the entity is in a 3D Skybox.
- Only available for . Multiplies the size of the model. Does not alter the physics collisions in most cases, however. Negative values are accepted. Takes two values separated by a space. The first is the target model scale. The second value is the number of seconds the change in scale will be spread over.
modelscalekeyvalue can be AddOutputed as a workaround for other games with this input missing.
Warning: Negative or extremely high values can cause crashes!
- Sets the entity's transparency to a number from 0 (invisible) to 255 (fully visible). Requires the entity to have its Render Mode (rendermode) set to a number other than

- Functions the same as
Kill, although this entity and any entities parented to it are killed on the same frame.
- Move with this entity. See Entity Hierarchy (parenting).
- Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.

- Fired whenever the object is detected to be outside the world. Specifically, it checks if the object is outside of the world's bounding box or if the object is traveling at over 2000 units per second in any cardinal direction.
- Fired when the player has
+used the prop.
- Fired when the player has dropped the prop (from either
+useor the gravity gun).
!activatoris the player.
