ACharacter::OnLaunched
#include "GameFramework/Character.h"
Access: public
Specifiers: UFUNCTIONBlueprintImplementableEventENGINE_API
Description
BlueprintImplementableEvent fired by LaunchCharacter immediately after the launch velocity is queued. Override this in Blueprint to react to the character being launched.
Caveats & Gotchas
- • This is a BlueprintImplementableEvent with no default C++ implementation. To handle launch reactions in C++, override LaunchCharacter() and call Super::LaunchCharacter() to preserve the Blueprint path.
- • The LaunchVelocity parameter reflects the requested velocity, not the final result — the actual velocity applied depends on the current character velocity and the bXYOverride/bZOverride flags.
