I’m casually trying to cook up a dashing mechanic for my game. However, I don’t really want to only be able to dash forward. That’s why I tried getting a good player direction detecting script. It’s just that no matter where I get my script or if I make the script myself, the scripts get the direction in which the player is moving according to the whole world. If the player is moving to the east no matter if they’re facing towards the east or not, the scripts will say that the player is moving east.
Idk if anyone gets what I mean, but I simply am just struggling to figure out how to determine if the player is walking left or right like a crab or if they are walking forward or backward like a normal sane person.
local Players = game:GetService("Players")
local Player = Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid")
local val = script.Parent:WaitForChild("direction")
Humanoid:GetPropertyChangedSignal("MoveDirection"):Connect(function()
if math.round(Humanoid.MoveDirection.X) == -1 then
val.Value = "Left"
print(val.Value)
elseif math.round(Humanoid.MoveDirection.X) == 1 then
val.Value = "Right"
print(val.Value)
elseif math.round(Humanoid.MoveDirection.Z) == -1 then
val.Value = "Forward"
print(val.Value)
elseif math.round(Humanoid.MoveDirection.Z) == 1 then
val.Value = "Backward"
print(val.Value)
end
end)
Just wanna say that I did not make this script, and it came from another forum post from a person I forgot. I do understand the script, tho.
You nee to use a dot product. This is a Vector operator, which calculates how close the direction of 2 lines are to each other.
local plr = game.Players.LocalPlayer
local char = plr.Character
local hum = char.Humanoid :: Humanoid
local hrp = char.HumanoidRootPart
hum:GetPropertyChangedSignal('MoveDirection'):Connect(function()
local dot = hrp.CFrame.LookVector:Dot(hum.MoveDirection)
print(dot)
end)
If it’s 1 or -1, it’s front to back. If it’s 0, it’s left to right.
Alternatively just use the MoveDirection for the dash which will allow dashing in any direction the player is walking in (Mobile and Gamepad can move in more directions than keyboard)
for ex: Root:ApplyImpulse(humanoid.MoveDirection * speed)
(dont use apply impulse for a dash like this though)
I’m kinda confused. How do I use MoveDirection if it’s a read-only thingy? I also don’t get what you mean by not using ApplyImpulse() for “a dash like this.”
Is this a local script or a server script?
If it’s a local script, just use UserInputService to get what keys the player presses and use remote events to convey that information to the server.
local UIS = game:GetService("UserInputService")
local CurrentDirection
local KeyToDirection = {
[Enum.KeyCode.W] = "Forward",
[Enum.KeyCode.S] = "Backward",
[Enum.KeyCode.D] = "Right",
[Enum.KeyCode.A] = "Left"
}
UIS.InputBegan:Connect(function(inp)
if KeyToDirection[inp.KeyCode] then
CurrentDirection = KeyToDirection[inp.KeyCode]
print(CurrentDirection)
RemoteEvent:Fire(CurrentDirection)
end
end)
I successfully made the dash directly use the move direction. I also scrapped the use of a separate script for detecting the moving direction of the player, and having everything inside the main dash script
local me = script.Parent
local debounce = false
local input = game:GetService("UserInputService")
local anim = script.Animation
local player = game.Players.LocalPlayer
local bar = me.Parent.TextLabel
local event = game.ReplicatedStorage.dash
local hum = player.Character:WaitForChild("Humanoid")
local function ultramove()
if hum:IsA("Humanoid") then
local movedirection = hum.RootPart.CFrame:VectorToObjectSpace(hum.RootPart.AssemblyLinearVelocity)
hum.RootPart.AssemblyLinearVelocity = hum.RootPart.CFrame.LookVector * ((movedirection.Z /-1) * 3) + Vector3.new(0, 1, 0)
hum.RootPart.AssemblyLinearVelocity = hum.RootPart.CFrame.RightVector * (movedirection.X * 3) + Vector3.new(0, 1, 0)
print("z:" .. hum.MoveDirection.Z)
print("x:" .. hum.MoveDirection.X)
end
local track = player.Character.Humanoid:LoadAnimation(anim)
bar.BackgroundTransparency = bar.BackgroundTransparency + 0.5
track:Play()
event:Fire()
end
me.MouseButton1Up:Connect(function()
if bar.BackgroundTransparency < 0.9 then
if player.Character.Humanoid.WalkSpeed > 16 then
if player.Character.Humanoid.Sit == false then
ultramove()
end
end
end
end)
input.InputBegan:Connect(function(key)
if key.KeyCode == Enum.KeyCode.LeftShift then
if bar.BackgroundTransparency < 0.9 then
if player.Character.Humanoid.WalkSpeed > 16 then
if player.Character.Humanoid.Sit == false then
ultramove()
end
end
end
end
end)
Now I’m struggling with figuring out how to use both the LookVector and RightVector without them overriding each other and ruining the ultra velocity build up dash.
