@Kowbell didn’t thought about reddit. I will try it!
@rYuxq i’ve done most of the Tutorials already, but i think i also do some blueprint tutorials, so i get a better feeling at coding in Unreal. Thx for this link https://docs.unrealengine.com/latest/INT/Gameplay/index.html this will help me definitly!
@DEFNIQUE I have experience in C, C# and Java. But i just doesn’t come along with the class descriptions within the Unreal Documentation.
