h2d.col.Circle - Heaps.io Game Engine

The circular hitbox implementation of a 2D Collider.

Constructor

`inlinenew(x:Float, y:Float, ray:Float)`

Create new Circle collider.

Parameters:

`x`	X position of the Circle center.
`y`	Y position of the Circle center.
`ray`	Radius of the circle.

Variables

`ray:Float`

Radius of the circle.

`x:Float`

Horizontal position of the Circle center.

`y:Float`

Vertical position of the Circle center.

Methods

`inlinecollideBounds(b:Bounds):Bool`

Test if this Circle collides with the given Bounds b.

`inlinecollideCircle(c:Circle):Bool`

Tests if this Circle collides with the given Circle c.

`contains(p:Point):Bool`

Tests if Point p is inside this Circle.

`inlinedistanceSq(p:Point):Float`

Returns a squared distance between the Circle center and the given Point p.

`inlinelineIntersect(p1:Point, p2:Point):Array<Point>`

Tests if this Circle intersects with a line segment from Point p1 to Point p2.

Returns:

An array of Points with intersection coordinates. Contains 1 Point if line intersects only once or 2 points if line enters and exits the circle. If no intersection is found, returns null.

`inlineside(p:Point):Float`

Returns a squared distance between the Circle border and the given Point p.
