unity3d - 如何在电晕中创建滑动控件

Question

我正在尝试使用 Corona 创建游戏，但我不知道如何制作滑动控件。我想制作一个可以根据您滑动的方向沿 x、-x、y、-y 移动的角色。需要任何建议，因为我迷路了。此代码当前使用按钮来移动玩家，当按下按钮时，玩家会朝那个方向移动。我想将按钮按下更改为滑动。移动事件在底部，按钮按下事件在中间。

local backdrop = display.setDefault("background", 1, 1, 1)

local physics = require("physics")
physics.start()

local square = display.newRect( 0, 0, 5, 5 )
--print(square)

_W = display.contentWidth; -- Get the width of the screen
_H = display.contentHeight; -- Get the height of the screen

motionDown = 0;
motionUp = 0;
motionRight = 0;
motionLeft = 0;
motionSquare = 5

speed = 4

local left = display.newRect(0,0,_W/2,_H/1.19)
    left.x = _W/4.5; left.y = _H/2;

local right = display.newRect(0,0,_W/2,_H/1.19)
    right.x = _W/1.25; right.y = _H/2;

local top = display.newRect(0,0,_W,_H/5.5)
    top.x = _W/2; top.y =0;

local bottem = display.newRect(0,0,_W,_H/5.5)
    bottem.x = _W/2; bottem.y =_H;

    player = display.newImage("player.png", display.contentCenterX, display.contentCenterY)
        player.x = math.random(10,_W-10)
        player.y = math.random(10,_H-10)

    player:toFront(player)

    physics.addBody( player, "static" )


    function left:tap()   --Left
            motionDown = 0;
            motionUp = 0;
            motionRight = 0;
            motionLeft = -speed;

            local square = display.newRect( 0, 0, 5, 5 )
            square.strokeWidth = 3
            square:setFillColor( 0 )
            square:setStrokeColor( 0, 0, 0 )
            square.x = player.x + 10 ; square.y = player.y;

            local function moveSquare (event)
                square.x = square.x - motionSquare;
                end
                Runtime:addEventListener("enterFrame", moveSquare)
        return square
    end
        right:addEventListener("tap",right)

您是否已经找到了解决方案？我之前已经回答过类似的问题，我将使用相同的示例：

local function globalTouchHandler(event)

    local swipeLength = math.abs(event.x - event.xStart) 
    print(event.phase, swipeLength)

    local t = event.target
    local phase = event.phase

    if (phase == "began") then

    elseif (phase == "moved") then

    elseif (phase == "ended" or phase == "cancelled") then

        if (event.xStart > event.x and swipeLength > 50) then 
            -- left
        elseif (event.xStart < event.x and swipeLength > 50) then 
            -- right
        end 
        if (event.y < event.yStart and swipeLength > 50) then
            -- up
        end
    end
end

Runtime:addEventListener("touch",globalTouchHandler)
