node trigger?

[mlefevre]

The first issue is I am trying to trigger an attribute when a value on another is hit. For example an attr goes oscillated from 0 to 1. When 0 is hit another attribute becomes -1 and when 1 is hit that same attribute goes to 1 until 0 is hit and it switches again...

The choice node seems a good way to go, since you're describing a change in integer value.

EDIT***
Nevermind, only works one way. Only half of what you want.

pseudo code:

create a locator
add two attributes, attrA and attrB
connect attrA to conditionNode.firstTerm
set conditionNode.secondTerm to 0
set colourIfTrueR to -1
create choice node
connect choiceNode.selector to attrB
connect conditionNode.outColorR to choiceNode.selector

Thank you, yes it "hold on to the value" and therefor would not work in this case. I don't think maya has such a trigger or counter to get invoked free of connections. It seems very simple but since my hands seem tied very frusterating.

hey Andrei, whaddup? Shouldnt an expression be able to do the job?

Hi Jan I just saw this sorry about the late reply, yes I did end up using a runtime espression for this. It is still dirty but did the trick. I guess if I really want a trigger node I should write it and hand it to Autodesk...
