I made a quick tool that can animate SMBX graphics, so long as they don't have any specific frame style. I tried my best to model how I believe SMBX animates its graphics. This should help to test your animations without loading SMBX too often.
Nerd pseudo-code stuff:
Code: Select all
SourceRect = Rectangle(X, Y * CurFrame, NPCwidth, NPCheight)
If CurFrame >= TotalFrames
CurFrame = 0
End If
If you run into any errors, check if you have the right numbers inputted. If it still doesn't work, PM me or leave a reply.
