i copied the Blueprintclass FPS_Character from the Realistic Rendering Sample to my own Project to try something out. But the Problem is that i get an error if i try to compile the blueprint, that the Input Axis got no Reference. Do you know how I can fix that?
You need to add the relevant input axis in the project settings of the project.
Basically you will have a block on the Character blueprint that says something like “Input Axis Jump” or “Input Axis Move” … you need to go to the Project Settings and add a new Input Axis called Jump or Move and then add a key binding.
Alternatively you can just use a “Key Event” in the Character Blueprint and link that to the offending node.
The node should be indicated by a yellow block that says Warning when you view the blueprint.
