Properties

Property group 'Destructible'

bSupportChunksInSupportFragment

Type: bool

Modifiers: const

If this is checked, then only chunks that are children of a FracturedStaticMesh support fragment are considered for support.

bSupportChunksTouchWorld

Type: bool

Modifiers: const

If this is checked, then only chunks that touch the world are considered for support.

Default value: True

DestructibleParameters

Type: PhysXDestructible.PhysXDestructibleParameters

Modifiers: editinline

Destructible parameters - damage thresholds, crumble particle systems, etc.

Default value:

Member	Value
bAccumulateDamage	True

Functions

Native functions

Init

native function Init ()

NativeSpawnEffects

native function NativeSpawnEffects ()

Native code for SpawnEffects

NativeTakeDamage

native function NativeTakeDamage (int Damage, Controller EventInstigator, Object.Vector HitLocation, Object.Vector Momentum, class<DamageType> DamageType, optional Actor.TraceHitInfo HitInfo, optional Actor DamageCauser)

Native code for TakeDamage.

TakeRadiusDamage

simulated native function TakeRadiusDamage (Controller InstigatedBy, float BaseDamage, float DamageRadius, class<DamageType> DamageType, float Momentum, Object.Vector HurtOrigin, bool bFullDamage, Actor DamageCauser, optional float DamageFalloffExponent)

Overrides: Actor.TakeRadiusDamage

(Description copied from Actor.TakeRadiusDamage)
Take Radius Damage by default scales damage based on distance from HurtOrigin to Actor's location. This can be overridden by the actor receiving the damage for special conditions (see KAsset.uc). This then calls TakeDamage() to go through the same damage pipeline.

Parameters:

• InstigatedBy - instigator of the damage
• BaseDamage -
• DamageRadius - from Origin)
• DamageType - class
• Momentum - float)
• HurtOrigin - origin of the damage radius.
• bFullDamage - if true, damage not scaled based on distance HurtOrigin
• DamageCauser - the Actor that directly caused the damage (i.e. the Projectile that exploded, the Weapon that fired, etc)
• DamageFalloff - allows for nonlinear damage falloff from the point. Default is linera.

Returns:

Returns amount of damage applied.

TakeDamage will hide/spawn chunks when they get shot.
