The definition of lucax constant under luco2da

It’s all basicCocos2dConstants.luaIn the file, I feel that it is more convenient and intuitive to use than the C + + version

frameworks/cocos2d-x/cocos/scripting/lua-bindings/script/Cocos2dConstants.lua

In the frameworks / cocos2d-x / cocos / scripting / Lua binding / script / directory, there are many other. Lua files that have well-defined APIs, which are worth looking at and have a clear idea. For example, in thecocos2d.luaThe method of quickly generating point object defined incc.p()The related methods were as follows

--Point
function cc.p(_x,_y)
    if nil == _y then
         return { x = _x.x, y = _x.y }
    else
         return { x = _x, y = _y }
    end
end

function cc.pAdd(pt1,pt2)
    return {x = pt1.x + pt2.x , y = pt1.y + pt2.y }
end

Another example isjson.luaMediumencodeanddecodeMethodsAudioEngine.luaThe global variables defined in can be used directlyAudioEngineLua, these functions are easy to use, it is worth to see the use of these files.
