Creating an Effect (Blueprint)

Effects are split into:

  • Effect settings: UEDInteractionEffect (the class you select in the component arrays)
  • Effect runtime: UEDInteractionEffectInstance (spawned and ticked while the effect plays)
  1. Create a Blueprint class derived from UEDInteractionEffectInstance.
  2. Implement the event entry points:
    • On Start (ReceiveStart)
    • On Tick (ReceiveTick)
    • On Finish (ReceiveFinish)
  3. Create a Blueprint class derived from UEDInteractionEffect.
  4. Set InstanceClass to your instance Blueprint class.
  5. Add your effect settings class to the arrays in UEDInteractionEffectsComponent.

Template Blueprint​

The plugin adds an asset factory entry:

  • ED Interaction Effect Instance Blueprint
  • ED Interaction Effect Blueprint

When you create the instance blueprint, it comes with the three events already placed in the graph as a starting template.

Accessing interaction data​

Inside the instance Blueprint, call:

  • GetEffectContext()

This returns a FEDInteractionEffectContext with:

  • TargetComponent, bTargetIsStaticMeshComponent, bTargetIsSkeletalMeshComponent
  • InteractableActor, InteractableLocation
  • InstigatorViewLocation, InstigatorViewDirection
  • ResolvedHitLocation, ResolvedHitNormal, ResolvedHitBoneName

The hit location is resolved from the instigator view ray; if there is no component hit, the closest collision point is used as fallback.
