bHasShownMissingSoundWarning Source code

Used so we only display the 'missing sound' warning once

ChunkHealth Source code

Current health of each chunk

DeferredPartsToSpawn Source code

Array of parts that are waiting to be spawned in an upcoming tick

ExplosionFractureSound Source code

Cached sound for large fractures.

MI_LoseChunkPreviousMaterial Source code

This is the material that was set on this FracuredStaticMeshActor before we overrode it with LoseChunkOutsideMaterial

PartImpactEffect Source code

Cached info for part impacts

SingleChunkFractureSound Source code

Cached sound for single chunk fractures.

SkinnedComponent Source code

Skinned component which will handle rendering for FracturedStaticMeshComponent

FracturedStaticMeshActor

bBreakChunksOnActorTouch Source code

If true, detach parts when an Actor with bCanCauseFractureOnTouch contacts them. Actor must not be blocked by this FSMA.

ChunkHealthScale Source code

Allows controlling how much 'health' chunks have on a per-instance basis

FractureCullMaxDistance Source code

Maximum distance from player where actor will be allowed to fracture (scaled by global settings.)

FractureCullMinDistance Source code

Minimum distance from player where actor will ALWAYS fracture, even when outside the view frustum (scaled by global settings.)

FracturedByDamageType Source code

Set of damage types that can cause pieces to break off this FSAM. If empty, all damage types can do this.

FracturedStaticMeshComponent Source code

MaxPartsToSpawnAtOnce Source code

Maximum number of rigid body parts to spawn off per actor, per frame

OverrideFragmentDestroyEffects Source code

Allows you to override particle effects to play when chunk is hidden for just this actor.

DeferredPartToSpawn Source code

Info about a fracture part that should be spawned in an upcoming Tick
bExplosion:

TRUE if this part was spawned because of an explosion

ChunkIndex:

Index of the chunk to spawn

InitialAngVel:

Exit angular velocity for this chunk

InitialVel:

Exit velocity for this chunk

RelativeScale:

Relative scale

BreakOffIsolatedIslands Source code

Find all groups of chunks which are not connected to 'root' parts, and spawn them as new physics objects. Updates FragmentVis with new chunks that get hidden by the process.

BreakOffPartsInRadius Source code

Util to break off all parts within radius of the explosion

Explode Source code

Break off all pieces in one go.

FractureEffectIsRelevant Source code

Specialized to handle explicit effect instigators. Also, handles None instigators -- these are special weapons (eg dummyfire) and are always relevant. Also, for fractured static meshes we only spawn effects if

HideFragmentsToMaximizeMemoryUsage Source code

Hide some percentage of the fragments from this mesh to maximize memory usage - does not spawn physics pieces etc

HideOneFragment Source code

Hide one fragment from this mesh - does not spawn physics pieces etc

IsFracturedByDamageType Source code

Util for checking if this damage type will cause fracture.

NotifyHitByExplosion Source code

Let kismet know that we've been hit
@param InstigatorController - the player that caused the explosion
@param DamageAmount - how much damage was caused
@param DmgType - the type of damage caused

PostBeginPlay Source code

RemoveDecals Source code

This function will remove all of the currently attached decals from the object. Basically, we want to have decals attach to these objects and then on state change (due to damage usually), we will just detach them all with the big particle effect that occurs it should not be noticeable.

ResetHealth Source code

Used to init/reset health array.

ResetVisibility Source code

Unhides all fragments

SetLoseChunkReplacementMaterial Source code

This will possibly set the material on the FracturedMesh after we have lost a chunk.

SpawnDeferredParts Source code

Gives the actor a chance to spawn chunks that may have been deferred
@return Returns true if there are still any deferred parts left to spawn

SpawnPart Source code

Spawn one chunk of this mesh as its own Actor, with the supplied velocities and scale relative to this Actor.

SpawnPartMulti Source code

Does the same as SpawnPart, but takes an array of chunks to make part of the new part.

TakeDamage Source code

TakeDamage will hide/spawn chunks when they get shot.
