Thanks, that was what I needed. I don't know anything about opengl yet, so this is a bit mystical for me, but I will have to learn some of it in the future, to do things like "show green ellipse around selected agents" etc.

What was meant in the comments about group? I didn't understand this:

##    TODO:
##        needs a proper group for the batch,
##        push / pop of attribute bit probably want to go to the group

Trying to make a grid for a menu, but that code makes the FPS from from
300 to ~55.
Is there a better way to do it, since colorlayer is not batchablenode?


I would use a custom CocosNode that internally use a batch.
An example near what you want can be  this test_batch_vertex_list.py,

Be sure to read the comments in that code.
