Ok, help needed...... RPG game....

Question

ok, i am out of ideas. i thought i cud make the player move, by making a grid layout and adding him to the layout, then noticied that it adds based on components, and not like an array (i thought with gridlayout u cud just go and do add(component, 5, 5) but u can't....and i tried adding blank components, but all that does is lag the comp.....maybe a 10x10 is to much.....anyone else give me ideas on how to make gridlike movement? plz help, (my code is a little large, so maybe i can send it to u through email? )

Answer 1

ok, i am desperate, so i am posting my code.
