Hello,
I’m new to the forum, and have had a look round but couldn’t find what I was looking for so I thought I’d ask. Sorry if this is in the wrong section or anything.
I have a python script that creates a cube and you can set the RGB values with sliders, but to see the effect of this you have to press the ok button. My query is that is it possible to see the effects of changing a slider instantaneously on the cube rather than having to press another button?
I’ve included the code if I didn’t explain what I meant very well, but I’m not sure if I put it in correctly (every forum has different rules about including scripts). Also the formatting doesn’t seem to work so all the indents are missing I’m afraid, but you can get the idea from reading it!
Any help would be most appreciated!
Thanks,
Mel
