attribute create

[breadbox]

how do you use a variable that is created in the attribute create sop?

i have a simple network that I want to use one single value to control in multiple expressions I can see that I have created the variable "mySpeed", but i cant get the syntax correct in the xform sop to read that variable?

You access variables by prefixing them with the $. $F, $TX, $BBY, etc. In your case you want $mySpeed.

does that actually work? I could not get it to work. what I did get to work was this.

point("../attribcreate1",$PT,"mySpeed",0)

let me know if there is an easier way this sort of makes the expression really long, just to use a custom variable.

in fact I think its better to use in this case to create a custom float field in the xform node itself. that way I can reference it by using ch(parm)

You are using a transform node. It does not work with point and primitive locals. In the attribute create, set class to Detail.
