iphone - 如何根据用户在 corona sdk 中触摸对象的时间来选择在单个触摸事件上从两个函数中调用哪个函数

Question

我正在创建一个对象，我希望它在我对其应用触摸事件时使其可拖动，如果用户触摸该对象超过 5 秒，则该对象不能作为可拖动对象工作，但我必须调用其他一些函数，之后我想清除计数器，以便在下次触摸后重新初始化......如何在电晕中实现它我正在尝试使用 Timer = os.time() 但无法获得完美的结果。请提出任何想法...谢谢

local function callfunc( event )
    local phase = event.phase
      if "began" == phase then
         Timer = os.time()
      if Timer>5 then
         func1()
        else
         func2()
    end
end

Runtime:addEventListener("touch",callfunc)

Answer 1

i'm assuming that you cannot get what you achieve because you did not remove the listener when going to another function see my code as a reference:

local function func1()

--set the object as draggable 

end

local function func2()
--remove the listener of the func1() and set another listener here
--call other function here

end

local function callfunc( event )
    local phase = event.phase
      if "began" == phase then
         Timer = os.time()
      if Timer>5 then
         func1()
        else
         func2()
    end
end

Runtime:addEventListener("touch",callfunc)

you can post another snippet of your code where the problem occurs if the idea above does't work since i only assume the problem that you have encountered. its hard to point out where the problem occur if there is only a snippet of code.

触摸事件传递的事件表有事件发生的时间。我会在开始阶段存储 event.time。然后，当您进入第一个移动阶段时，如果时间超过 5 秒，则以一种方式行事，否则以另一种方式行事。
