Button Keeps Breaking In Hda

[SpencerL]

Hey,

I have created an HDA that has a button that sets off a render from a rop inside my HDA. The problem is whenever I bring in my HDA node the button breaks and I have to re-establish the link to the ROP by putting the path to that ROP into the "Auto-Link" parameter in the "Type Properties". Once I do that then the button works fine. Im not sure what I am doing wrong. Thanks.

Hey Spencer,

Maybe try just skipping the parameter linking and use a callback script in the button parameter to fire off the ROP. Try:

opparm /obj/geo/myRop execute ( 1 )

*or*

render /obj/geo/myRop

...I think either one of those should work, but I've always used the "opparm" approach and it's worked for me... I gave the example using an absolute path but you'll probably want to use a relative path to your Rop since it's in an HDA... hope this helps!

or you could link it with the !!ch()!!

Thanks Excel, thats what I was looking for. the final syntax that I used was:

opparm -C `opfullpath("ropnet1/mantra1")` execute ( 1 )

Thanks!
