ios - 我如何解决电晕中的导演问题

Question

local function connectedToServer(event)


    client:send("connected")
    cleanAll()

    function a()
        director:changeScene( "PlayerClient" )
    end
    timer.performWithDelay( 1000, a() ,1) 




end
Runtime:addEventListener("autolanConnected", connectedToServer)

这是我的代码行，在第一次更改场景时出现问题，director:changeScene( "PlayerClient" ) 它运行良好，但在第二次运行时，当我暂停游戏或输赢后，我返回菜单，然后再次开始游戏，该行有错误director:changeScene( "PlayerClient" )。有谁能够帮我？

错误是

2013-01-09 14:51:25.871 Corona Simulator[478:707] Runtime error

Answer 1

尝试这个 ：

timer.performWithDelay(1000,function () direcor:changeScene( "PlayerClient" ) end)

代替：

function a()
   direcor:changeScene( "PlayerClient" )
end

timer.performWithDelay(1000,a(),1)
