I’m following this tutorial [5. Animation Blueprint - Idle and Walk States][1]

My graph looks exactly like the step 15. Everything was OK while playing but when I pressed Esc key to quit the game, the Message Log window fired this error:

This is the MyAnimationBlueprint screenshot:

What’s wrong with it?

I had the same error, used this solution from JenAnty, and it worked. But sometimes I MUST use GetPlayerCharacter, which still gives me that error.

Here, from the animation blueprint, I set a property in the character blueprint. If my toon is moving, speed is not < 1, setting FALSE to Orient Rotation to Movement. If I’m not moving, speed is < 1 setting it to TRUE. But I have to invoke the function Get Player Character. So … any other workaround? Or a solution to that error?

I finaly learned how to deal with that problem. The error happens when the GetPlayerCharacter is triggered before the load process is finished. So we have to put “Is Valid” in the pipeline, before the “SET Orient Rotation…”.
