fromMinMax

Creates a rectangle from two coordinate values.

Parameters

• v1 Vec2
• v2 Vec2

Examples

cc.Rect.fromMinMax(cc.v2(10, 10), cc.v2(20, 20)); // Rect {x: 10, y: 10, width: 10, height: 10};

contain

Checks if rect contains.

Parameters

• a Rect Rect a
• b Rect Rect b

Examples

var a = new cc.Rect(0, 0, 10, 10);
var b = new cc.Rect(5, 5, 5, 5);
var c = new cc.Rect(20, 20, 10, 10);
cc.Rect.contain(a, b); //  1;
