Hello,

I have 2 custom attribute sliders that effect the x and y rotation of a box ”ParamX and ParamY”. I have a third attribute which is a check box”Pos_1”. My aim is to effect the 2 sliders by clicking the check box.When the check box is off, the sliders should be able to move freely, when the check box is on, the sliders should be locked to the position i determin.

I am using the wire parameters by controling the sliders using the check box. I have written the expression “if (Pos_1 == true) then (ParamX == 90)” and i get the following error ”unable to convert:undefined to type:Float”

I think i’m going down the right road but am getting something slightly wrong. Can anyone help me with this?

Thanks

ParamX.value = 90, assuming “ParamX” is the actual slider object.

But I’m unsure whether if/then constructs are permissible in expressions. Expressions are basically calculations, not scripts. Look up “expression techniques” in the main Max help.

If that is being done in a rollout of some kind then it should work.

Assuming Pos_1 is the name of the button then

on Pos_1 pressed do ( stuff here )

should do it. Needs to be after the button definition but still within the rollout definition.
