How do I change the FPS sample controler Jump to directional thruster?

I’m new to Unreal so I apologize, I looked but was unable to find a resource that could help me. If anyone has a good direction that would be awesome.

I disabled world gravity because I’m making a fps mech space game for fun. I’m using the sample fps controller that comes with the newbie back and im looking at the blueprint and I want to script it so when I press space bar it adds a force in that direction. Thus spacebar will be a thruster that adds force with a combination of mouse look and directional keys.

For example if your strafing left but looking forward and press thruster you will strafe thrust. Basically you will keep doing whatever direction you pressed thrust towards until you balance it to a stop or fly around as if you were in real space.

I have no idea where to even start to change the controller complete newbie.

Quick question, do you want your character to thrust horizontally or are you going to be floating around Dead Space style?

I want him to thrust in 3 dimensional space, if your strafing left and press thrust it will thrust, now if your looking up and to the left it will thrust up basically your mouse look will control the vertical thrusting, and a s w d will be your horizontal thrust control.
