setPosition(x,y) 方法失败

Cocos2d-x Lua
#1

shortcodes.lua 都是调用这个的.

function Node:pos(x, y)

self:setPosition(x, y)

return self

end

Cocos2d: LUA ERROR: :0: error in function ‘setPosition’.

 argument #2 is 'number'; 'const CCPoint' expected.
#2

tolua++ 导出里面，不是有么
tolua_function(tolua_S,“setPosition”,tolua_Cocos2d_CCNode_setPosition00);
tolua_function(tolua_S,“setPosition”,tolua_Cocos2d_CCNode_setPosition01);

#3

我明白了 是ccs的widget里面木有
