To define a polygon, pass a variable number of **Position2D** structs representing the points of the polygon.
|
||
|
|
|
||
|
|
```cs
|
||
|
|
var polygon = new Polygon(
|
||
|
|
new Position2D(0, 0),
|
||
|
|
new Position2D(-1, -1),
|
||
|
|
new Position2D(1, -1),
|
||
|
|
new Position2D(1, 1),
|
||
|
|
new Position2D(-1, 1)
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|

|
|
Be careful not to define a concave Polygon, as this will cause the results of collision detection to be incorrect.
