Needing help from coders.

I need help to make collisions in the game, and particle system (particles appear when player walk). Please, I need some help. Hope someone help me to make my dream, a RPG game.

you could use somthing like this

if keyboard.up then walk=1 y+=1 else walk=0 end

and

if walk==1 then screen.drawSprite("walk_particle",player.x,player.y,20)

i hope that helps

Thanks, levi_
