lua - How can I check If the event listener is running or not ....?

Question

I want to check if it is possible to identify that the event listener is running or not. For example, I have achieved the following:

local function doTurn (event)   
    rotatingRect:applyAngularImpulse(50)   
end  
    Runtime:addEventListener( "enterFrame", doTurn )

Answer 1

您可以在该函数上打印以查看事件是否触发查看此代码

local function doTurn (event)   
    rotatingRect:applyAngularImpulse(50)
    print("This function is being triggered")
end  
    Runtime:addEventListener( "enterFrame", doTurn )
