MAX SCRIPT SLIDER HELP
show user profile  ccampbell
I have what hope is a quick max scripting question.

I am creating a horizontal slider within a rollout and want to select a scecific face and then move it according to the direction i scrub the slider. In that if i scrub left the face always moves positively in the x axis else negatively in the x axis.

Any help would be awesome. I'm very new to max scripting. Ive pasted an example of the code i have now. it works now but when scrubbing in negative integers the face only moves in one direction and same for the positive.

The logic is a little flawed.

The on changed handler updates val continuously. If you were to print out val in the listener (just add print val in the handler), you'd see 1 2 3 etc when moving to the right. So you first move the face of 1 unit, then of 2 units, then 3, etc. Don't forget that moving is not like setting the position, it's adding to the current position. So by the time you reach 3, you've already added 1+2+3 = 6 units to the starting position.
And that's why it moves toward positive x when you go from 0 to 10, but also when going from 10 to 0. In both cases, val is positive (or null).
Lucky for you you used integers. Had you chosen floats, you'd get a lot more intermediate values!

Try something like this (it moves the selected object(s), not a face):


Btw, this works as well with floating point values.

edit: oh, and check this for more on maxscript ;)
