How do I bind "W" to jump using scripts?
Hi, I'm extremely new to roblox coding and I want to make a traditional fighting game. The first thing I'm trying to do is make it so W jumps and S crouches, but I'm not even sure where to start. I'm sure it's possible because in the "Infinite Runner" preset game you use W to jump. I don't have any code to show because I haven't been able to find anything related to my problem. Thanks!

It's not very complicated. You just need to understand how to get a player's keypress and need to understand remote events.
Make sure this is a local script inside of startergui:
--LOCAL SCRIPT
--PUT THIS SCRIPT INSIDE OF STARTERGUI
local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local mouse = player:GetMouse()
local jumpEvent = game:GetService("ReplicatedStorage"):WaitForChild("jumpEvent") --Waits for the remoteEvent to be created by the server
mouse.KeyDown:Connect(function(key)
if string.lower(key) == "w" then
jumpEvent:FireServer() --send a message to the server to tell the player to jump
end
end)
Make sure this is a server script:
--SERVER SCRIPT
local jumpEvent = Instance.new("RemoteEvent", game:GetService("ReplicatedStorage")) -- create the remoteEvent
jumpEvent.Name = "jumpEvent"
jumpEvent.OnServerEvent:Connect(function(player) -- receive the message from the local script
print("Jumped")
player.Character.Humanoid.Jump = true
end)
The reason we need two scripts is because server scripts cannot get a player keypress and local scripts cannot make the player jump. So we use the remote events to let them communicate to each other.
