ShapeMerger

Introduction

The ShapeMerger can be used to merge shapes together to create one larger shape. This is used by the TileEditor to create level collision.

Code Example

The following code creates two Polygons - one is the shape of a rectangle, the other is a hexagon. The rectangle is offset, then the two shapes are merged into one. Add the following using statement:

using FlatRedBall.Math.Geometry;

Add the following to Initialize after initializing FlatRedBall:

Polygon firstPolygon = Polygon.CreateEquilateral(
    6, // Number of sides
    5, // radius
    0); // angle of first point

Polygon secondPolygon = Polygon.CreateRectangle(
    4, // ScaleX
    4); // ScaleY

secondPolygon.X = 5;
secondPolygon.Y = 5;

// This call modifies the first polygon
ShapeMerger.Merge(firstPolygon, secondPolygon);
ShapeManager.AddPolygon(firstPolygon);
