h2d.col.IBounds - Heaps.io Game Engine

An integer-based bounding box.

Static methods

`staticinlinefromPoints(min:IPoint, max:IPoint):IBounds`

Returns a new IBounds instance from given min/max IPoints.

`staticinlinefromValues(x0:Int, y0:Int, width:Int, height:Int):IBounds`

Returns a new IBounds instance from given rectangle.

Parameters:

`x`	Rectangle horizontal position.
`y`	Rectangle vertical position.
`width`	Rectangle width.
`height`	Rectangle height.

Constructor

`inlinenew()`

Create new empty IBounds instance.

Variables

`height:Int`

Height of the bounding box. Equivalent of yMax - yMin.

`width:Int`

Width of the bounding box. Equivalent of xMax - xMin.

`x:Int`

X-axis position of the bounding-box top-left corner. Modifying it alters both xMin and xMax.

`xMax:Int`

X-axis right-most bounds box point.

`xMin:Int`

X-axis left-most bounding box point.

`y:Int`

Y-axis position of the bounding-box top-left corner. Modifying it alters both xMin and xMax.

`yMax:Int`

Y-axis bottom-most bounding box point.

`yMin:Int`

Y-axis top-most bounding box point.

Methods

`inlineaddBounds(b:IBounds):Void`

Adds IBounds b to the IBounds, expanding min/max when necessary.

`inlineaddPoint(p:IPoint):Void`

Adds IPoint p to the IBounds, expanding min/max when necessary.

`inlineaddPos(x:Int, y:Int):Void`

Adds position x and y to the IBounds, expanding min/max when necessary.

`inlineall():Void`

Sets bounds to cover maximum area (-2147483648...0x7FFFFFFF).

`inlineclone():IBounds`

Returns new copy of this IBounds instance.

`inlinecontains(p:IPoint):Bool`

Tests if IPoint p is inside the IBounds.

`inlinedoIntersect(b:IBounds):Void`

Sets this IBounds min/max values to a result of intersection between this IBounds and given IBounds b. See intersection to get new instance of IBounds as intersection result.

`inlinedoUnion(b:IBounds):Void`

Sets this IBounds min/max values to a result of combining this IBounds and given IBounds b. Equivalent of addBounds.

`inlineempty():Void`

Clears IBounds into an empty state.

`inlinegetCenter():IPoint`

Returns a new IPoint containing center coordinate of the IBounds.

`inlinegetMax():IPoint`

Returns a new IPoint containing xMax and yMax.

`inlinegetMin():IPoint`

Returns a new IPoint containing xMin and yMin.

`inlinegetSize():IPoint`

Returns a new IPoint containing size of the IBounds.

`intersection(b:IBounds):IBounds`

Returns new Bounds instance containing intersection results of this IBounds and given IBounds b.

`inlineintersects(b:IBounds):Bool`

Tests if this IBounds instances intersects given b IBounds.

`inlineisEmpty():Bool`

Tests if bounding box is empty. IBounds are considered empty when either xMax is less than or equals to xMin or yMax is less than or equals to yMin.

`load(b:IBounds):Void`

Copies min/max values from given IBounds b to this IBounds.

`inlineoffset(dx:Int, dy:Int):Void`

Moves entire bounding box by dx,dy.

`inlineset(x:Int, y:Int, width:Int, height:Int):Void`

Sets bounds from given rectangle.
