Single-color rectangles/shapes?

Is there a way to make a rectangle and load a single color into it, preferably with an alpha channel?
On a similar note, is there vector graphics?

You can use the draw2Dprimitive method. Using colored vertices you can draw colored shapes, and with this, you can achieve results similar to a vectorial rasterizer

(maybe this should be moved to the help forums?)

Ah, the filled square was what I was looking for. As for the other things, it seems there aren't options for rotating any of these primitives, strange.

Yes, 2d primitives wree originally developed for simple GUI elements only. Thus, the API did not provide rotation and other things. You should instead use 3d elements in those cases.

@ ping-pong2012:
You could just draw a simple scene node with 4 vertices forming a rectangle.

Sorry the suggestion was so late.
