Contains() [1/2]

RectI.Contains

(

other_rect

)

Check if current rectangle fully contains the other provided rectangle. That means to check if the other rectangle is fully inside current one.

Parameters

[in]

other_rect

The other provided rect.

Returns

true means current rect fully contains the other rectangle, while false means not.

Contains() [2/2]

RectI.Contains	(	x	,
		y
	)

Check if current rectangle contains the provided point. That means to check if the provided point is inside current one.

Parameters

[in]	x	The x coordinate of the provided point.
[in]	y	The y coordinate of the provided point.

Returns

true means current rect contains the provided point, while false means not.

Height()

RectI.Height

(

)

Get the height of the rect.

Returns

The height of the rect.

Intersect() [1/2]

RectI.Intersect	(	left1	,
		top1	,
		right1	,
		bottom1
	)

Intersect with a rect.

Parameters

[in]	left1	The left of the rect to intersect with.
[in]	top1	The top of the rect to intersect with.
[in]	right1	The right of the rect to intersect with.
[in]	bottom1	The bottom of the rect to intersect with.

Returns

None.
