Hello there! This is my first time really posting on the devforum so sorry if I’m doing anything wrong.
1.What do you want to achieve?
I am making a combat type system and I’m trying to figure out a way how when a hitbox (Part) touches a player, it moves the npc/player using a bodyvelocity
What is the issue?
I want the npc/player to move in the direction they were hit in
here’s a video to show the issue https://gyazo.com/63a88831648637f7e2ba01cb9e1b7168
I had another issue but I fixed it by adding a wait()
What solutions have you tried so far? Did you look for solutions on the Developer Hub?
I’ve tried googling it up but couldn’t find anything , and I’ve tried putting a variable to detect what the hitbox’s CFrame was but it was pretty delayed compared to when I remove the part that uses the hitbox CFrame
Heres the full script (Server Script) :
game.ReplicatedStorage.Attack.OnServerEvent:Connect(function(Player)
-- Variables
local PlayerWhoPressed = Player.Character.Name
local Character = Player.Character
local HRP = Character.HumanoidRootPart
local Part = Instance.new("Part")
-- Spawn Hitbox
wait(0.2)
Part.Parent = game.Workspace
Part.CFrame = HRP.CFrame + HRP.CFrame.LookVector * 2.35
Part.Anchored = true
Part.BrickColor = BrickColor.new("Really red")
Part.Transparency = 0.75
Part.CanCollide = false
Part.Size = Vector3.new(5, 5, 4.5)
Part.Touched:Connect(function(Hit)
-- Variables
local Sound = math.random(1,2)
local PartCFrame = Part.CFrame
local Humanoid = Hit.Parent:FindFirstChild("Humanoid")
if Humanoid and Humanoid.Parent.Name ~= PlayerWhoPressed then
local HitHRP = Humanoid.Parent.HumanoidRootPart
local BodyVelocity = Instance.new("BodyVelocity")
BodyVelocity.MaxForce = Vector3.new(1,0,1) * 30000
BodyVelocity.Velocity = HitHRP.CFrame.LookVector * -100
BodyVelocity.Parent = HitHRP
Humanoid.WalkSpeed = 0
for i= 1,8 do
wait(0.1)
Humanoid.Health -= 0.3
BodyVelocity.Velocity *= 0.7
wait()
end
wait(1.5)
Humanoid.WalkSpeed = 16
BodyVelocity:Destroy()
Part:Destroy()
else
wait()
Part:Destroy()
end
end)
wait(0.1)
Part:Destroy()
end)
end)
The line works fine, but you need to use a different equation to calculate velocity from the Player (hitting the other person) to the person they hit.
I’ve simplified your code a little bit and changed the equation so as to resolve your issue.
Essentally, it takes the Player’s HumanoidRootPart position and subtracts the position of the person who got hit. It then gets the Unit of the negative Vector3 value to calculate the direction.
Here is the full code:
game.ReplicatedStorage.Attack.OnServerEvent:Connect(function(Player)
local PlayerWhoPressed = Player.Name
local Char = Player.Character
local Root = Char:WaitForChild("HumanoidRootPart", 1)
if Root == nil then return end
local Part = Instance.new("Part")
wait(0.2)
Part.Parent = game.Workspace
Part.CFrame += Root.CFrame.LookVector * 3
Part.Anchored = true
Part.BrickColor = BrickColor.new("Really red")
Part.Transparency = 0.75
Part.CanCollide = false
Part.Size = Vector3.new(5, 5, 3.5)
Part.Touched:Connect(function(Hit)
local Humanoid = Hit.Parent:FindFirstChild("Humanoid")
if Humanoid ~= nil and Humanoid.Parent.Name ~= PlayerWhoPressed then
local BodyVelocity = Instance.new("BodyVelocity")
BodyVelocity.MaxForce = Vector3.new(1,0,1) * 30000
BodyVelocity.Velocity = (-(Root.Position - Humanoid.Parent.HumanoidRootPart.Position).Unit * 2.5)
BodyVelocity.Parent = Humanoid.Parent.HumanoidRootPart
Humanoid.WalkSpeed = 0
for i= 1,10 do
Humanoid.Health -= 0.5
BodyVelocity.Velocity *= 0.7
wait()
end
wait(1.5)
Humanoid.WalkSpeed = 16
BodyVelocity:Destroy()
Part:Destroy()
else
wait()
Part:Destroy()
end
end)
wait(0.1)
Part:Destroy()
end)
Another Alternative way is to get the direction the player hitting is facing.
This is a lot simpler, and you can use this method instead of my other one if you decide to.
(Root is the PlayerWhoPressed’s HumanoidRootPart)
FULL CODE:
game.ReplicatedStorage.Attack.OnServerEvent:Connect(function(Player)
local PlayerWhoPressed = Player.Name
local Char = Player.Character
local Root = Char:WaitForChild("HumanoidRootPart", 1)
if Root == nil then return end
local Part = Instance.new("Part")
wait(0.2)
Part.Parent = game.Workspace
Part.CFrame += Root.CFrame.LookVector * 3
Part.Anchored = true
Part.BrickColor = BrickColor.new("Really red")
Part.Transparency = 0.75
Part.CanCollide = false
Part.Size = Vector3.new(5, 5, 3.5)
Part.Touched:Connect(function(Hit)
local Humanoid = Hit.Parent:FindFirstChild("Humanoid")
if Humanoid ~= nil and Humanoid.Parent.Name ~= PlayerWhoPressed then
local BodyVelocity = Instance.new("BodyVelocity")
BodyVelocity.MaxForce = Vector3.new(1,0,1) * 30000
BodyVelocity.Velocity = Root.CFrame.LookVector * 100
BodyVelocity.Parent = Humanoid.Parent.HumanoidRootPart
Humanoid.WalkSpeed = 0
for i= 1,10 do
Humanoid.Health -= 0.5
BodyVelocity.Velocity *= 0.7
wait()
end
wait(1.5)
Humanoid.WalkSpeed = 16
BodyVelocity:Destroy()
Part:Destroy()
else
wait()
Part:Destroy()
end
end)
wait(0.1)
Part:Destroy()
end)
Hi there, I’ve tried both of your solutions, however, when I run it in game, it doesn’t seem to be working? also PlayerWhoPressed is supposed to be the player character because if the player somehow is inside the hitbox which happens a lot, they won’t take damage from their own attack, it’s not supposed to be the Player.
Edit: I’ve also updated my script so it’s more organized/redable
, and I’ve tried putting a variable to detect what the hitbox’s CFrame was but it was pretty delayed compared to when I remove the part that uses the hitbox CFrame
