Set Size of a loadingbar

cocos2d-x Lua
#1

How can I set the size of a loadingbar in lua?!

In C++ i can call setSize

In lua I can do … what exactly? The api reference isn’t showing a setSize() function on the lua side.
How can I do that?

I think you should call setContentSize because setSize was deprecated, so it weren’t bound to Lua.
