Builtin collision functions. The ic argument stores the collision position.
fn lineToLine
fn lineToLine*(b1, e1, b2, e2: th::Vf2, ic: ^th::Vf2): bool {
Checks for a collision between 2 lines specified by their end points.
fn vf2ToQuad
fn vf2ToQuad*(p: th::Vf2, q: th::Quad, ic: ^th::Vf2): bool {
Checks for a collision between a vf2 and a quad.
fn lineToQuad
fn lineToQuad*(b, e: th::Vf2, q: th::Quad, ic1, ic2: ^th::Vf2): bool {
Check for a collision between a line and quad edges.
fn quadToQuad
fn quadToQuad*(q1, q2: th::Quad, ic: ^th::Vf2): bool {
Check for a collision between two quads.
fn vf2ToRect
fn vf2ToRect*(p: th::Vf2, r: rect::Rect): bool {
Check for a collision between a vf2 and a rectangle.
fn rectToRect
fn rectToRect*(r1, r2: rect::Rect): bool {
Check for a collision between two rects
