code：— filename： test.luacocos2d.ccDrawLine(createPoint(10, 10),createPoint(100, 100))
the run screen has no effect。
ccDrawLine is only a method，not return object or class，so in the lua script ，can’t use draw method。
ccDrawLine only call in CCNode:draw()
It seems to me that ccDrawLine is not exported for Lua, I’m missing something?
I found a way to add primitive rendering functions to CCRenderTexture, I’ll uploaded later on my Killa branch, however I only need points and lines but you’ll could extend the method if interested.
