3rd Person Power Up Tutorial Spawn Volume Error

Development Programming & Scripting
1

So I just finished part 8 and when I add a spawn volume to my game it appears below the room and it can not move. Also I don’t see the inherited method WhereToSpawn as in the tutorial. I followed every step correctly and don’t know why this happens.

Hey Nik1-

Can you provide the code for your spawn volume class? Can you make sure that WhereToSpawn is set as a UPROPERTY in code so that it is visible to the editor?

Thank you for interest but I have found the solution. It seems that KismetMathLibrary does not actually load the method definitions. I had to get the code from the method RandomPointInBoundingBox and paste it where I needed it.
