How to draw a line with Lua？

cocos2d-x Lua
#1

code：
— filename： test.lua
cocos2d.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。

help me！！！

#2

ccDrawLine only call in CCNode:draw()

#3

It seems to me that ccDrawLine is not exported for Lua, I’m missing something?

#4

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.
