This [[:Category:Stage Functions|function]] requires the following variables to be declared in your [[Global Script]]: | |||
float ang (the measure of the angle) | |||
float n (used internally) | |||
float t2 (used internally) | |||
float sin (sine of the angle) | |||
float cos (cosine of the angle) | |||
float tan (tangent of the angle) | |||
You may rename these if you wish, but that means changing the code to match. All of them must be floats. | |||
