That's the error, every sprite should have a z index, right?
or do I need to define it?
This is the code that's giving the error

By putting z=(z), you're confusing the interpreter because it's taking "z=" as function name instead of an operation. It should be

 self.z = z

 self.z = z

It gives the same error

 

[Golisopod User]

What does self even reference? The Fight Menu? Because you don't need to set Z for that

 

[#Not Important]

@spiritButton or @spiritButton.bitmap I think.
Its default essentials apart from the @spiritButton and @spiritbitmap
Edit: I spelt this part wrong (whoops)addSprite("spiritButton",@spritButton) I'll get back 2 u once I've tried it

 

[mgriffin]

Your thing is nil, it says so right in the error message.

EDIT: Your typo might fix that. Not sure.

 

[#Not Important]

It probably will, because I spelt it wrong, so it's nil

 

[Marin]

self.z = z is identical to self.z = (z) which is identical to self.z=(z). All you're doing is introducing spaces and parentheses, which don't change anything about it. z= is the method name, so that couldn't be a problem. Proof: self.method(:z=).call(z)

I solved it thanks, it was my spelling error...
