How would I output a single bang when an XYZ coordinate falls within a certain range. For example, the X range could be between 20-40, the Y range 40-60 and the Z range 50-60.

Trying a few different things here involving variation of expressions, [select], [change] etc. and nothing seems to be working out.

There is possibly an object I don't know of that handles this task quite simply?

Thanks in advance for any help

No bang will be output when the coordinate

@Martinukai Hi,
assuming x y and z output 1 when in range, testing for all 3 like this would work
bang-when-3-are-true.pd

this one using [expr] should do, what you want.
xyz_true.pd
