Entity description

Discovery Object.

Keyvalues

HL:A BasePropPhysics:

Min Damage to Hurt (minhealthdmg) <integer>

The prop will ignore any damage events if the damage is less than this amount.

Shadow Cast Distance (shadowcastdist) <integer>

Physics Impact Damage Scale (physdamagescale) <float>

Scales damage energy when this object is hit by a physics object. NOTE: 0 means this feature is disabled for backwards compatibility.
Set to 1.0 for materials as strong as flesh, smaller numbers indicate stronger materials.

Impact damage type (Damagetype) <choices>

Value	Description
0	Blunt
1	Sharp

Damaging it Doesn't Push It (nodamageforces) <choices>

Used to determine whether or not damage should cause the brush to move.

Value	Description
0	No
1	Yes

Accept damage from player held objects (acceptdamagefromheldobjects) <boolean>

Set to true so the player can bash this with held props.

Scale Factor For Inertia (inertiaScale) <float>

Scales the angular mass of an object. Used to hack angular damage and collision response.

Mass Scale (massScale) <float>

A scale multiplier for the object's mass.

Health Level to Override Motion (damagetoenablemotion) <integer>

Health Level to Override Motion" : 0 : "If specified, this object will start motion disabled. Once its health has dropped below this specified amount, it will enable motion.

Physics Impact Force to Override Motion (forcetoenablemotion) <float>

If specified, this object will start motion disabled. Any impact that imparts a force greater than this value on the physbox will enable motion.

Sound to make when punted (puntsound) <sound>

AI AddOn (addon) <string>

If specified this object will use this addon behavior when installed in a composite AI

interactAs ([todo internal name (i)]) <string>

comma-separated list of interaction layers

Force Nav Ignore (forcenavignore) <boolean>

If set, NPCs will ignore this prop when navigating.

Force NPC Exclude (forcenpcexclude) <boolean>

If set, NPC movement will ignore this prop

Auto Convert back from Debris (auto_convert_back_from_debris) <boolean>

If set, this prop will automatically convert back to interactive debris after coming to rest as Debris.

Inputs

HLA BasePropPhysics:

Wake

Wake up this physics object, if it is sleeping.

Sleep

Put this physics object to sleep. It will wake if given the Wake input, or if force is applied to it. Note that physics objects go to sleep automatically after coming to rest for a while, so you don't really need to use this.

EnableMotion

Enable physics motion/collision response.

DisableMotion

Disable physics motion/collision response.

EnablePickup

Enable player pickup of this prop.

DisablePickup

Disable player pickup of this prop.

DisableFloating

Disable fluid/floating simulation to reduce cost.

SetBodyGroup <string>

Sets bodygroup. Format is <BodygroupName,index>

physdamagescale <float>

Set the Physics Impact Damage Scale for this character. NOTE: 0 means this feature is disabled for backwards compatibility.

EnableDamageForces

Damaging the entity applies physics forces to it.

DisableDamageForces

Damaging the entity does *not* apply physics forces to it.

EnablePuntSound

Allow this prop to play its own sound when punted.

DisablePuntSound

Prevent this prop from playing its own sound when punted.

SetAutoConvertBackFromDebris <boolean>

Set whether or not this prop should automatically convert back to interactive debris after it comes to rest as debris.

AddAttribute <string>

Add an attribute with a value of 1.

RemoveAttribute <string>

Remove an attribute.

VScript:

CallPrivateScriptFunction <string>

Calls a script function from this entity's private script scope.

CallGlobalScriptFunction <string>

Calls a script function in the global script scope.

Outputs

HLA BasePropPhysics:

OnMotionEnabled

Fired when motion is enabled on this prop, either via 'Health Level to Override Motion' or from the EnableMotion input.

OnAwakened

Fired when this entity becomes awake (collision/force is applied to it while it's asleep).

OnPhysGunPickup

Fired when the player picks up the prop with the physcannon or +USE.

OnPhysGunPunt

Fired when a player punts this object with the physgun.

OnPhysGunOnlyPickup

Fired when a player picks this object up WITH THE PHYSGUN. +USE pickups do not fire this output.

OnPhysGunDrop

Fired when the player drops the prop with the physcannon or USE.

OnPlayerUse

Fired when the player tries to +USE the prop. This output will fire only if the Generate output on +USE spawnflag is set.

OnPlayerPickup

Fired whenever the player picks up this prop (with the physcannon or with +USE).

OnOutOfWorld

Fired whenever the prop is out of the allowed world bounds.
