Par Exec Dat issues

General TouchDesigner Discussion
1

I’ve created a container and a custom param of an integer slider from 0-50. Inside the container I pull a Parameter CHOP and a ParExecute DAT and link the two. (OPs set to par1 and the Parameters set to *) I set the ParExec script to print(par.name, par.val) in the valueChanged method. When I change the slider on the container, I can see the Par1 CHOP update, but the ParExec never fires a print statement.

Now when I create a Constant CHOP and hook the ParExec up to it, changing the value of the Constant does trigger the ParExec. Is there any reason why this should differ from a Parameter CHOP?

Par Exec Test, right click on the container1 breadcrumb and hit Parameters… then slide the Index slider. No print statements in the Textport. But change the ParExec to look at the constant1 OP and it works as expected.

You need to point the Par Exec DAT to the OP whos parameter you want to monitor.

So if you want to monitor the Index parameter on the parent COMP container1 , point it to there.
working version attached, the Parameter Exec DAT’s parameter OPs now points to .. which is the parent COMP container1
