if i make v4 ill add the original stuff i put into v2, this is meant to have the very very basics of a sonic game only. Super Sonic you can make on your own, either as a seperate character or a variable.
I suggest making a variable for super sonic.
1, never use drag and drop lol
it seems easier but trust me it isnt, in GM1 its automatically drag and drop but there are code blocks.
2, it's quite simple to make super sonic actually, you create a variable for it, like for example, literally just 'super', then you make it so any code that damages you doesnt work when super, and make sonic's speed faster when super.
Sorry if my explaining things confuses you, i've never been good at explaining how things work lol.
states and animations are in the enum,
for super you would literally just add 'superform = 0' to the create event.
i suggest you start reading up on this GameMaker Studio 2 Language Reference
Very simple. (sorry i didnt get notified of this one for some reason)
