Events

Mesh Loaded​

Called when the Deformable Mesh (Asset) is fully prepared and loaded.

NOTE: You should check bIsMeshLoaded before binding/waiting for this event to trigger, because the mesh may already be loaded!

Mesh Initialized​

Called when the the actual mesh component (RMC/PMC) is initialized and visible.

NOTE: You should check bIsMeshInitialized before binding/waiting for this event to trigger, because the mesh may already be initialized!

Mesh Updated​

Called after a LOD (RealtimeMesh) or a Section (ProceduralMesh) is updated. Every hit triggers at least one update. Most of the time the After Impact makes more sense to use.

  • RealtimeMesh: SectionIndex is always -1
  • ProceduralMesh: LodIndex is always -1

After Impact​

Event for impact handling. Called after an impact happened. Can be used e.g. for damage display.

Hit Type: What kind of hit happened? There are three type of hits:

  • Normal: A normal hit that just happened and was triggered by OnComponentHit. This is independent of replication.
  • History: A hit that happened in the past and was triggered by replication of the HitHistory.
  • ForwardedNormal: A hit that just happened and was triggered by OnComponentHit of another Deformable Mesh Component and was forwarded to this component. For more information see Attachments.
Version 2.1

Previously there was a Is Real Impact parameter but it has been replaced with the Hit Type. A Normal hit equals a Real Impact.

Example

Most of the time you want to ignore History hits, because they are hits that happened in the past. Let's take the Impact Effects (SFX/VFX) for example, they should play/spawn when the component hits something. This obviously should only happen when a hit just happened and that's why we ignore History hits in this case.

Impact Data: This contains information about the hit, e.g. the location, strength and even the original hit result, but the hit result is only available for normal and forwarded normal hits. Impact Strength is between Min Relevant Impact Strength and Max Hit Deform Percentage.



Before Impact​

This event is similar to After Impact but it triggers before the hit is processed.
