CCTMXLayer and primitives..

I'm hoping someone can maybe point me in the right direction...

I would like to draw a primitive (ccDrawLine) from point a to point b on a map. I have the tile map layer that I want to draw on, and I have the cords I need using positionAt(), so I know where I need to place the points for the line.

the problem I am having is I am not sure how I can tell the system I want the lines drawn on a specific layer, or if I should be sub-classing the CCTMXLayer and overriding the draw function to draw on the map...

Is there a way I can tell the system I want to draw on a specific layer without descending?

I just descended all the TMX stuff and create my own layers with primitive drawing methods available to the outside.

If anyone does know a way I would still be interested to know how to do it from outside a layer, if it's even possible.

You have to create a subclass of CCNode and then do your drawing inside the Node's draw method. This is so the OpenGL context is setup before you draw.

CCTMXLayer it self is a CCSpriteSheet and draw on it means:

1) override the draw funxtion of the parent CCLayer.
2) make the CCTMXLayer's Z order correctly.
