Trying to Scale Root motion in blueprint

Development Character & Animation
1

Anyone able to help me with this one? I have a nice root motion attack moving forward x units. i’d like to be able to dynamically adjust this for gameplay. I found a function in the engine called
“set anim root motion translation scale” but its not usable in bp and i don’t know enough about visual studio or c++ to know what i’m supposed to do to get access to it. Anyone kind enough to walk me through that process?

For anyone facing this problem in the future: the function that they are talking about is ACharacter::SetAnimRootMOtionTranslationScale().

As the original post states, there’s no direct access to it in blueprints. There are a few ways to go about it, but the easiest one would be subclassing ACharacter in C++, and wrapping up that function in your custom BlueprintCallable function. That’s the bare minimum example:

UCLASS()
class AMyCharacter : public ACharacter
{
	GENERATED_BODY()

public:
	UFUNCTION(BlueprintCallable, DisplayName="Set Anim Root Motion Translation Scale", Category="Character")
	void K2_SetAnimRootMotionTranslationScale(float InAnimRootMotionTranslationScale)
	{
		SetAnimRootMotionTranslationScale(InAnimRootMotionTranslationScale);
	}
	
	UFUNCTION(BlueprintPure, DisplayName="Get Anim Root Motion Translation Scale", Category="Character")
	float K2_GetAnimRootMotionTranslationScale() const
	{
		return GetAnimRootMotionTranslationScale();
	}
};
