I’m have a basic 1 v 1 SSBB type game but i want a char select screen so i can have a vary of characters. theres a game called super smash flash and its pretty good, and has A CHARACTER SELEC SCREEN…though they dont teach u how to make them…if u guys cud check them out, and maybe help me out? that’d be grreat…it’s like u pull the button(1p,2p.etc) onto a char, and it selects it.
