我如何让一个角色用键盘向上/向下移动？ [罗布洛克斯/Lua]

Question

我是 Roblox 脚本的新手（虽然我过去做过很多 Unity 开发）基本上我试图让用户四处飞行。将重力变为0，并在下面编写了ControlScript。我想让 Space/Shift 允许人们上/下。出于某种原因，这只是不会修改 y 轴位置。我一直在摆弄这个大约 4 个小时，但我找不到问题所在。

提前感谢您的帮助！

-- Declare variables
local userInputService = game:GetService("UserInputService")
local runService = game:GetService("RunService")
local player = game.Players.LocalPlayer

    if inputObject.KeyCode == Enum.KeyCode.W then

Answer 1

如果您不确定哪个按钮对应于给定的操作，则键盘和鼠标映射很有用。要查看此地图：

1. 点击位于屏幕左上角的菜单按钮。

2. 您可以在此屏幕上进行一些鼠标调整。只要开发者没有为游戏设置相机模式，您就可以在两种不同的模式之间切换并打开/关闭Shift Lock。此外，您可以设置头像的移动模式。有关这些设置的更多信息，

3. 要查看 Roblox 鼠标和键盘控件，

按照 Evan Wrynn 的建议，使用速度来完成这项工作。这是 ControlScript：

-- Declare variables
local userInputService = game:GetService("UserInputService")
local runService = game:GetService("RunService")
local player = game.Players.LocalPlayer
local MyBody

local children = workspace:GetChildren()

for i=1,#children do
   if children[i].Name == player.Name then
   MyBody = children[i].HumanoidRootPart
   end
end

local moveVector = Vector3.new(0,0,0)
local velocity = 0

-- Handle inputBegan event (when player first presses a key)
userInputService.InputBegan:connect(function(inputObject)
  if player.Character then
    if inputObject.KeyCode == Enum.KeyCode.W then
      moveVector = moveVector + Vector3.new(0,0,-1)
    end
    if inputObject.KeyCode == Enum.KeyCode.A then
      moveVector = moveVector + Vector3.new(-1,0,0)
    end
    if inputObject.KeyCode == Enum.KeyCode.S then
      moveVector = moveVector + Vector3.new(0,0,1)
    end
    if inputObject.KeyCode == Enum.KeyCode.D then
      moveVector = moveVector + Vector3.new(1,0,0)
    end
    if inputObject.KeyCode == Enum.KeyCode.Space then
      moveVector = moveVector + Vector3.new(0,-1,0)
      velocity = 10
    end
    if inputObject.KeyCode == Enum.KeyCode.LeftShift then
      moveVector = moveVector + Vector3.new(0,1,0)
      velocity = -10
    end
  end
end)

-- Handle inputEnded event (when player releases a key)
userInputService.InputEnded:connect(function(inputObject)
  if player.Character then
    if inputObject.KeyCode == Enum.KeyCode.W then
      moveVector = moveVector + Vector3.new(0,0,1)
    end
    if inputObject.KeyCode == Enum.KeyCode.A then
      moveVector = moveVector + Vector3.new(1,0,0)
    end
    if inputObject.KeyCode == Enum.KeyCode.S then
      moveVector = moveVector + Vector3.new(0,0,-1)
    end
    if inputObject.KeyCode == Enum.KeyCode.D then
      moveVector = moveVector + Vector3.new(-1,0,0)
    end
    if inputObject.KeyCode == Enum.KeyCode.Space then
      moveVector = moveVector + Vector3.new(0,1,0)
      velocity = 0
    end
    if inputObject.KeyCode == Enum.KeyCode.LeftShift then
      moveVector = moveVector + Vector3.new(0,-1,0)
      velocity = 0
    end
  end
end)

-- On renderstepped update the character's motion based on what keys
-- are currently being pressed
runService.RenderStepped:connect(function()
  if player.Character then
    player:Move(moveVector, true)
    MyBody.Velocity = Vector3.new(MyBody.Velocity.X,velocity,MyBody.Velocity.Z)
  end
end)
