jadacreata 0 Report post Posted March 25, 2014 Hey all, Couldn't find any forum about this. I want to parent a line to rotate with a radial wipe transition. Would be best to attached both to a slider. Any ideas? or Any idea what the expression is to convert 360 rotation to 100%? thank you, J Quote Share this post Link to post Share on other sites
RVA8 0 Report post Posted March 25, 2014 Some Algebra will do the trick. So it's simple cross-multiply and divide like this: R P ---- = ---- 360 100 R is your rotation value and P is your percentage value. So when cross multiplied gives us: 100*R = 360*P then divide to isolate your desired variable, in this case R R = (360*P)/100 and there's your expression.

RVA8 0 Report post Posted March 25, 2014 That is your full expression. Just replace the P variable with your percentage property from your transition effect. If you just drop this directly on your rotation property you can ditch the "R=" part of the equation or just put an "R" as the last line of your expression. Either way should work.

wysee 0 Report post Posted March 26, 2014 You can use the linear function in your expression. It does exactly what you want linear(0,360,0,100) will map 360 degrees to 0-100 for exemple Quote Share this post Link to post Share on other sites
