Drawing a polygon

Recommended Posts

I'm using a graphics object to draw a filled polygon. The graphics is updated in "render()" since the polygon changes shape slightly each frame. I'm doing the actual drawing semi-manually since I'm applying a custom smoothing function to the polygon. When the number of vertices of the polygon increases to hundreds, fps starts to drop.


Not all the points are visible to the camera, though, but phaser is not able to make use of this given that I'm specifying all the points on the smoothed polygon in render(). The solution that comes to mind is to manually intersect the polygon with the camera's view port, eliminating all the polygon parts that are not visible. Can phaser make my life easier somehow?
