Tutorial 87: Angular Controls
🕑 Added 2017-09-08 04:00:01 +0000 UTC In Tutorial 85: Integrated Textures, we made an interesting shadow out of a displaced layer. I thought it might be useful to change the default controls of Displacement Map from Max Horizontal and Max Vertical Displacement to Angle and Distance sliders. So I built that. And I continued to apply that expression to similar parameters—like position. That allowed me to animate things diagonally as easily as I can move things in X or Y. Because of that, we can put a bunch of things together going in the same direction and animate simple sliders like in our example GIF below.Horizontal Only:
a = effect("Angle Control")("Angle");
d = effect("Distance")("Slider");
x = Math.cos(degreesToRadians(a));
x*d;
Vertical Only:
a = effect("Angle Control")("Angle");
d = effect("Distance")("Slider");
y = Math.sin(degreesToRadians(a));
y*d;
Both (for position style controls):
a = effect("Angle Control")("Angle");
d = effect("Distance")("Slider");
x = Math.cos(degreesToRadians(a));
y = Math.sin(degreesToRadians(a));
value+[x*d,y*d];
Thanks for your support patrons!

We only started selling project files after #117. For anything under 117, they're on our website if available. This one is not.
