How do i make a map look 2D

I want to make a Smash Brothers map, so when u push the left arrow you go left, right arrow to the right, up to the jump, etc. but I don't know how to make it like that. So could someone help me?

(off topic) I would like to add a picture but i don't know how

Tweak camera, use elevators as platforms, use triggers with arrow key events and learn some trig math and the like for jumping.

Thanks for that, but do you know how the jumping triggers work?

Edit: And how should i "tweak the camera"

Holding Ctrl+Right Button and Draggin should move your current camera on the map screen, then just create a new camera, and set said camera to the current view.

Jumping isn't as trivial as you might believe, so I suggest you to do a search on the trigger forum.

Okay i'll check the trigger place, thanks for everything.
