Function Documentation

ARC_FRect_CastToRect()

ARC_Rect ARC_FRect_CastToRect

(

ARC_FRect *

rect

)

casts FRect to Rect

Parameters

rect	ARC_FRect to be casted

Returns

ARC_Rect

ARC_FRect_CenterOn()

void ARC_FRect_CenterOn	(	ARC_FRect *	rect,
		ARC_FRect *	bounds )

centers rect on given bounds

Parameters

rect	ARC_FRect to be centered
bounds	ARC_FRect area to center rect on

ARC_FRect_CollideAndSlide()

void ARC_FRect_CollideAndSlide	(	ARC_FRect *	rect,
		ARC_Vector2 *	velocity,
		ARC_FRect *	wall )

checks for a ARC_Rect on ARC_Rect collision and slides on collision

Note

need to update this documenation to word it better

Parameters

rect	ARC_Rect that might collide with the wall
velocity	the ammount ARC_Rect will move
wall	ARC_Rect that might have collision with rect

Note

velocity is updated based on colliding, rect's values are not changed, velocity should be applied after

ARC_FRect_Intersects()

int32_t ARC_FRect_Intersects	(	ARC_FRect *	rect1,
		ARC_FRect *	rect2 )

checks if two ARC_FRects intersect

Parameters

rect1	ARC_FRect that will be checked against rect2
rect2	ARC_FRect that will be checked against rect1

Returns

1 if they intersect, 0 if they don't intersect

ARC_FRect_IntersectsPoint()

int32_t ARC_FRect_IntersectsPoint	(	ARC_FRect *	rect,
		ARC_Point *	point )

checks if ARC_FRect intersects with point

Parameters

rect	ARC_FRect that will be checked against point
point	ARC_Point that will be checked against rect

Returns

1 if they intersect, 0 if they don't intersect

ARC_Rect_CastToFRect()

ARC_FRect ARC_Rect_CastToFRect

(

ARC_Rect *

rect

)

casts Rect to FRect

Parameters

rect	ARC_Rect to be casted

Returns

ARC_FRect

ARC_Rect_CenterOn()

void ARC_Rect_CenterOn	(	ARC_Rect *	rect,
		ARC_Rect *	bounds )

centers rect on given bounds

Parameters

rect	ARC_Rect to be centered
bounds	ARC_Rect area to center rect on

ARC_Rect_Intersects()

int32_t ARC_Rect_Intersects	(	ARC_Rect *	rect1,
		ARC_Rect *	rect2 )

checks if two ARC_Rects intersect

Parameters

rect1	ARC_Rect that will be checked against rect2
rect2	ARC_Rect that will be checked against rect1

1 if they intersect, 0 if they don't intersect

ARC_Rect_IntersectsPoint()

int32_t ARC_Rect_IntersectsPoint	(	ARC_Rect *	rect,
		ARC_Point *	point )

checks if ARC_Rect intersects with point

Parameters

rect	ARC_Rect that will be checked against point
point	ARC_Point that will be checked against rect

Returns

1 if they intersect, 0 if they don't intersect

ARC_Rect_LineIntersects()

int32_t ARC_Rect_LineIntersects	(	ARC_Rect *	rect,
		int32_t *	x1,
		int32_t *	y1,
		int32_t *	x2,
		int32_t *	y2 )

checks if ARC_Rect intersects a line

Note

need to update this documenation to word it better
