Good day! I have an issue with set function!
I want to get the level Index. For that i create variable “LevelIndex” and make them public for manually input index for each Level End (Fig.3). On Begin Play i cast variable from my PlayerBall and want to set variable of level for my playerball (Fig.2) But to player always returns 0, or i suppose “Set” Function don’t overwrite Player’s variable/
I use UE 4.7.5
Please help!!!
