Disabling WASD/Arrow Key Movements?
Hi I'm creating sort of a 2D Endless Runner game, and I'm using this method... : http://wiki.roblox.com/index.php?title=Controlling_a_Player%27s_Character to make the player move on its own. However, if you use WASD or Arrow keys, that cancels the movement, and removing all control no longer allows you to jump. Is there a way to remove all WASD/Arrow Keys control while still being able to jump?

When you use this method of preventing someone from controlling, they cannot jump, but they are still able to jump. You can make them jump when they press a key, you can detect when they press a key though KeyDown or UnserInputService.
Making a player jump
There is a way to force a player to jump, In the humanoid there is a Jump property which is a boolean. If it is true, the player jumps once.
1 | workspace.Player.Humanoid.Jump = true |
Fun Facts about Jump property
- You can make an anti-jump script using the changed event:
1 | workspace.Player.Humanoid.Changed:connect(function(jump) |
2 | if jump == "Jump" then |
3 | workspace.Player.Humanoid.Jump = false |
4 | end |
5 | end) |
KeyDown
It's deprecated, you shouldn't use it.
1 | --LocalScript |
2 | local plyr = game:GetService("Players").LocalPlayer |
3 | local mouse = plyr:GetMouse() |
4 |
5 | mouse.KeyDown:connect(function(key) |
6 | if key:byte() == 32 then --32 is space. |
7 | plyr.Character.Humanoid.Jump = true |
8 | end |
9 | end) |
Fun Facts about KeyDown
- There is KeyUp which is not as popular as KeyDown.
UserInputService
Use InputBegan to see what keys the player pressed:
1 | --LocalScript |
2 | local plyr = game:GetService("Players").LocalPlayer |
3 | local uis = game:GetService("UserInputService") |
4 |
5 | uis.InputBegan:connect(function(key) |
6 | if key.KeyCode == 32 then |
7 | plyr.Character.Humanoid.Jump = true |
8 | end |
9 | end) |
Fun Facts about UserInputService
- You can now play roblox with a game console because of user input service!
Final Script
01 | --LocalScript |
02 | local plyr = game:GetService("Players").LocalPlayer |
03 | local uis = game:GetService("UserInputService") |
04 |
05 | for _, controller in pairs(game:GetService("ControllerService"):GetChildren()) do |
06 | controller:Destroy() |
07 | end |
08 |
09 | uis.InputBegan:connect(function(key) |
10 | if key.KeyCode == Enum.KeyCode.Space then |
11 | if plyr.Character:FindFirstChild("Humanoid") then |
12 | plyr.Character.Humanoid.Jump = true |
13 | end |
14 | end |
15 | end) |
Hope this helps!
What You Need To Do
- Use the
InputBeganEvent of UserInputService
This Event detects any user input. If you compare the value returned(the user input) with any KeyCode Enum, in your case.. 'Space', then you can activate the Jump Property of the character's Humanoid. this will make them jump
Code
01 | --UserInputService |
02 | local uis = game:GetService('UserInputService') |
03 | --Player |
04 | local plr = game.Players.LocalPlayer |
05 |
06 | --InputBegan |
07 | uis.InputBegan:connect(function(input) |
08 | --Check if the input is space |
09 | if input.KeyCode == Enum.KeyCode.Space then |
10 | --Activate Jump property |
11 | local hum = plr.Character:WaitForChild('Humanoid') |
12 | if hum then |
13 | hum.Jump = true |
14 | end |
15 | end |
16 | end) |
