Please tell me how to change 3 dimensional map to 2 dimensional arcade [vx]

I am trying to make an arcade style game, so don't need the player to go up. That I managed to do with a conditional branch that if the up button is pressed, you turn left or right. The problem is when the surface is uneven, the player can't jump and stop on an upper step. (I created a switch "jump", so when you press the up button then, he jumps, but goes through walls and solid objects, and stays on the same level.) Thank you to anyone who can help.

you'll have to script something for it or find a script that does the work for you, google RMVX plat former I'm sure you will turn up some results (well lest for XP i did)

Thank you, have googled and yahooed it and found Enterbrain's next product, IG Maker. Downloading trial version now, will see what it's like
