Blend Space

Blends 1-2 input parameters (e.g. speed × direction) across a 2D space of animations. Used for locomotion.

Damage number popup floating text in world space

Pattern: WBP_DamageNumber widget with TextBlock. On damage dealt: CreateWidget(WBP_DamageNumber) → SetText(Damage amount) → AddToViewport. Tick: ProjectWorldLocationToScreen(DamageLocation + UpOffset) → SetPositionInViewport. Timeline Alpha 0→1 over 1s: SetColorAndOpacity(FadeOut) + move up. OnFinished: RemoveFromParent. Alternative: use WidgetComponent in world space.

Overlap

Two collision shapes occupying the same space without blocking. Use for triggers (volume, pickup).

AddActorWorldOffset — move actor by world-space delta

Vertical Box

Lays out children top-to-bottom. Children's Size pins control how space is distributed.

K2_AddActorWorldOffset — move actor by delta in world space

K2_AddActorWorldOffset.

AddActorWorldRotation — rotate actor in world space

K2_AddActorWorldRotation — add delta rotation in world space for continuous rotation

K2_AddActorWorldRotation. Multiply rotation by DeltaSeconds for frame-rate independence.

Physics Body

A SceneComponent with simulate-physics enabled. Driven by forces, gravity, collisions instead of explicit transforms.
