gm_body_contains()

int gm_body_contains	(	gmBody *	body,
		double	x,
		double	y )

Checks if a point is contained within a body's collider.

Parameters

body	Pointer to the body to check.
x	The x-coordinate of the point.
y	The y-coordinate of the point.

Returns

1 if the point is inside the body, 0 otherwise.

gm_collision_detect()

gmCollision * gm_collision_detect	(	gmBody *	a,
		gmBody *	b )

Detects collision between two bodies.

Parameters

a	Pointer to the first body.
b	Pointer to the second body.

Returns

A pointer to a gmCollision structure if collision occurs, NULL otherwise.

int gm_mouse_in_circle	(	const double	x,
		const double	y,
		const double	r )

gm_mouse_in_rect()

int gm_mouse_in_rect	(	const double	x,
		const double	y,
		const double	w,
		const double	h )
