AActor::GetComponentsCollisionResponseToChannel
#include "GameFramework/Actor.h"
Access: public
Specifiers: virtualconst
Description
Returns the most restrictive collision response across all components for the given channel. If any component blocks the channel the result is ECR_Block; if any overlaps (and none block) the result is ECR_Overlap; otherwise ECR_Ignore.
Caveats & Gotchas
- • The result is the maximum response across all components — a single blocking primitive makes the whole actor appear to block even if every other component ignores that channel.
- • Components with collision disabled (ECollisionEnabled::NoCollision) contribute ECR_Ignore and will never raise the actor-level response on their own.
- • This function iterates all owned components and should not be called every tick on actors with large component counts.
