Collision functions, etc
Local Functions
| collision_point_circle1 (px, py, cx, cy, cr) | Check for collision/overlap of a point and a circle 44 tokens |
| collision_point_circle2 (px, py, cx, cy, cr) | Check for collision/overlap of a point and a circle 29 tokens and faster overflow and potential false positives for dxdx+dydy > 32767 |
| dist_circ_line_w (x, y, r, x0, y0, x1, y1, w) | Distance from circle to line with optional width Wide line includes a circular cap at each end Negative distance indicates depth of overlap |
