Question

我想实时找到我的玩家的x和y坐标，所以我知道在哪里进行下一级游戏。我目前正在使用LÖVE2D来运行我的代码。当我尝试打印player.x和player.y时，游戏运行正常，但没有坐标的文本输出。我试图改变文本所在位置，但这不起作用。任何帮助表示赞赏。注意：我今天刚刚开始使用Lua，所以请直言不讳。：）

love.graphics.setDefaultFilter('nearest','nearest')
function love.load()
  room1Image = love.graphics.newImage('room1.png')
  room2Image = love.graphics.newImage('room2.png')
  room3Image = love.graphics.newImage('room3.png')
  room1 = true
  room2 = false
  room3 = false
  player = {}
  player.x = 0
  player.y = 255
  player.speed = 5
  player.image = love.graphics.newImage('player.png')
end

function love.update(dt)
  if love.keyboard.isDown("left") then
    player.x = player.x - 5
  end
  if love.keyboard.isDown("right") then
    player.x = player.x + 5
  end
  if love.keyboard.isDown("up") then
    player.y = player.y - 5
  end
  if love.keyboard.isDown("down") then
    player.y = player.y + 5
  end
  if player.y >= 600 and room1 then
    room1 = false
    room2 = true
    player.y = 5
  end
  if player.y <= 0 and room2 then
    room1 = true
    room2 = false
    player.y = 600
  end
  if player.y >= 600 and room2 then
    room2 = false
    room3 = true
    player.y = 5
  end
  if player.y <= 0 and room3 then
    room2 = true
    room3 = false
    player.y = 600
  end


end

function love.draw()
  --draw background
  if room1 then
    love.graphics.draw(room1Image, room1Image.x, room1Image.y)
  elseif room2 then
    love.graphics.draw(room2Image, room2Image.x, room2Image.y)
  elseif room3 then
    love.graphics.draw(room3Image, room3Image.x, room3Image.y)
  end
  --draw player
  love.graphics.draw(player.image, player.x, player.y, 0, 5)
  end

如果要将某些内容输出到控制台，请使用love.graphics.print。这在游戏窗口中不可见。

如果您想向玩家展示一些文字（在游戏中），请在love.draw()内拨打local x,y = 0, 0 --coordinates at which the text is printed function love.load() end function love.update(dt) end function love.draw() love.graphics.print("This is something I want you to see.", x, y) end：

Lua在游戏中得到（x，y）玩家
