Keyvalues

BreakableProp:

Explosion Damage (ExplodeDamage) <float>
If non-zero, when this entity breaks it will create an explosion that causes the specified amount of damage. See also Explosion Radius.
Explosion Radius (ExplodeRadius) <float>
If non-zero, when this entity breaks it will create an explosion with a radius of the specified amount. See also Explosion Damage.
Sound to make when punted (puntsound) <sound> (in all games since Half-Life 2: Episode One)
Sound to make when punted by gravity gun.
Break Model Message (BreakModelMessage) <string>
"If set, will use this break model message instead of the normal break behavior."
Confirm:Is this new with Source SDK 2013...? It isn't in Alien Swarm or 2007 code but is in 2013. New with L4D?

Breakable (common):

Performance Mode (PerformanceMode) <choices>
Used to limit the amount of gibs produced when this entity breaks, for performance reasons.
Choices
  • 0: Normal
  • 1: No Gibs
  • 2: Full Gibs on All Platforms (Xbox 360, PS3, etc)
  • 3: Reduced gibs
Min Damage to Hurt (minhealthdmg) <integer>
If a single hit to the object doesn't do at least this much damage, the prop won't take any of the damage it attempted to give.
Pressure Delay (PressureDelay) <float>
Seconds to delay breaking from pressure. Allows creaking/groaning sounds to play.
Health (health) <integer>
How close to breaking the object is.
Maximum Health (max_health) <integer>
Health cannot exceed this amount.
Physics Impact Damage Scale (physdamagescale) <float>
Multiplier for damage amount when this entity is hit by a physics object. With a value of 0 the entity will take no damage from physics.
Breakable By (BreakableType) <choices> (only in Left 4 Dead series)
Who can break this?
  • 0: Everyone
  • 1: All Infected
  • 2: Only Tanks

Inputs

BreakableProp:

Break
Breaks the breakable.
SetHealth <integer>
Sets a new value for the breakable's health. If the breakable's health reaches zero it will break.
AddHealth <integer>
Adds health to the breakable.
RemoveHealth <integer>
Removes health from the breakable.
physdamagescale <float>
Sets Physics Impact Damage Scale. 0 means this feature is disabled for backwards compatibility.
EnablePhyscannonPickup
Makes the breakable able to picked up by the gravity gun.
DisablePhyscannonPickup
Makes the breakable not able to picked up by the gravity gun.
EnablePuntSound  (in all games since Half-Life 2: Episode One)
Allow this prop from playing its Punt Sound sound when punted by the gravity gun.
DisablePuntSound  (in all games since Half-Life 2: Episode One)
Prevent this prop from playing its Punt Sound sound when punted by the gravity gun.

Outputs

BreakableProp:

OnBreak
Fired when this object breaks. !activator is whatever breaks the object.
OnHealthChanged <float>
Fired whenever the health of the breakable has increased or decreased. This output automatically puts the new health amount as a decimal percent (e.g. 45% = 0.45) into the parameter box for inputs, if the mapper does not override the parameter with something else.
OnTakeDamage
Fired when damage is taken.
OnPhysCannonAnimatePreStarted
Fired when prop starts its ACT_PHYSCANNON_ANIMATE_PRE activity. Caused by the object being picked up by the gravity gun.
OnPhysCannonAnimatePullStarted
Fired when prop has started its ACT_PHYSCANNON_ANIMATE activity. ACT_PHYSCANNON_ANIMATE_PRE plays once, then ACT_PHYSCANNON_ANIMATE starts looping.
OnPhysCannonDetach
Fired when prop has started its ACT_PHYSCANNON_DETACH activity (caused by the gravity gun ripping it from a wall).
OnPhysCannonAnimatePostStarted
Fired when prop has started its ACT_PHYSCANNON_ANIMATE_POST activity (caused by the player letting the prop go from the gravity gun).
OnPhysCannonPullAnimFinished
Fired when prop has finished all gravity gun-related animations.
