u/fentbiggesthater

couldve sworn ive seen this somewhere before also, stolen? impressive
u/New_Core

Nah, its not stolen.. but its a remix of the one zachygreen did.. I made it in a different way but I posted it as a remix of his since its so alike looking.. If you mean you seen it even before that then there is always that chance someone made something simular before.. who knows ;)
u/lewdev

I totally saw this on StarFox on SNES! 😉

rainbow spinning bars, first dweet bear with me!

u/Xen

onlyneed to set width, extra tasty byte ;-)
u/sybarita

thanks ya i realized that after i did these ones super big accidentally, since i had already set it super wide the bottom half of the canvas was empty so i just changed the height val instead of scaling all the other values cause im lazy. used your guide to get started playing with these btw, thanks for that!
u/Xen

omg really? glad it helped :-)
