If conditions evaluate the specified statement, and run code based on the returned value of the evaluation. If conditions are boolean (true or false), and may be strung together.

Example code: 

ifdead { spawn BLOODPOOL killit }

If conditions may be used in conjunction with an else.


In a cascade of multiple ifs followed by an else if, the latter is bound to the outermost of the former ifs. Thus, the following code 

redefinequote 114 NOPE
ifvare 0 1 ifvare 0 0 redefinequote 114 ONE
else redefinequote 114 TWO

is equivalent to this explicitly-braced one: 

redefinequote 114 NOPE
ifvare 0 1 { ifvare 0 0 redefinequote 114 ONE
}
else redefinequote 114 TWO

and NOT this one, as with C-derived programming languages, 

redefinequote 114 NOPE
ifvare 0 1 { ifvare 0 0 { redefinequote 114 ONE
}
else redefinequote 114 TWO
}

and quote 114 contains the string 'TWO' after its execution.
