how to make variants of smb1 bowser

[Guitar200]

that can breaths only fire or throw hammer.

Currently it is impossible to do it, but you can make the SMB1 hammer/fire graphic invisible and not hurt the player.
Hope I helped a bit.

I think you should ask this to Catskart or Yoshi021. They're the best at Tea-Scripting.

Or, do what DaveDatCat101 told you to do..
