Hm, ok. Let’s start somewhere:
-
Have you tried using the Shift Event itself instead of the Action Mapping?
-
Have you tried printing some debug messages? For example tried to check if “Jump in Place” really did change your movement speed? (So to check if the Shift key worked there).
-
Have you tried (just for debugging) to change the Key you assigned in the Action Mappings to controll, to check if maybe the bindings are broken?
Because at the moment you have the key event and not the action mapping for the controll key. :X
You could also trie to make a 3rd Input.
- use Spacebar again for it and also click the “Shift” box at the right side. Call it “Sprint Jump” or something like that and on press/release you do both at once (movementspeed change and jump).
Tell me if something of this worked or the result of the debugging.
I hope i can get this working for you.
