Where are you using it?

In the player constructor… I’m assuming the issue is that he loads in before the level?

From what I understand, the GetWorld() is only a reference getter on your actor. GetWorld() could be not valid, but it does not mean the World is not up. Also, doing this in the constructor is probably not safe, since the constructor is called for every class at the start of the Editor (or Engine).

I personally use the GetWorld() from the GameInstance class to get my World Ref as it seems to be referenced there as soon as the GameInstance is created.

Hope this can help you.

Yup, got it. Thanks!

Solved thanks to Michaël Dubé. I just had to move it out of the player constructor.

I just switched my comment into answer, would be great if you can flag it as accepted :slight_smile:
