is there a way to turn a laser on or off when a certain variable = something. like {scene.my.hi=1} ? {laser on} : {laser off}}?

just turn the fadedist from 0 to something more than 0 (like 25)
like
laser : fadedist = {scene.my.fade}
option:
scene.my.var1 ? {scene.my.fade=0}:{scene.my.fade=25};

yup, as hiltropper said, just place an if script in the fade dist (in the script menu....)

For laser on use a value thats higher 0

For laser off, use a value of 0

Or just change the alpha to 0.

Thanks

Alpha only matters when you look at the actual laser itself. Zero alpha simply results in a random beam coming from an invisible source.

Thru scene.my, zero fadeDist is certainly the way to go, but if you are like me and don't like scene.my, your best bet is to put the laser on a box and change the color of the box. An opaque box will block the laser.

Oh wait, sorry, not alpha. Make the laser black. I was thinking of something else.
