Why won't my dummy move with LinearVelocity?

Asked by

2 years ago

So, I am trying to create a combat system, and I am currently experimenting with some things. I want to make a script that basically knocks up the nearest player (did not implement that yet, i am still experimenting) and i already ran into some issues.

01local dummy = game.Workspace.Dummy
02local dHum = dummy:FindFirstChild("Humanoid")
03local dHRP = dummy:FindFirstChild("HumanoidRootPart")
04 
05local UIS = game:GetService("UserInputService")
06local deb = false
07 
08UIS.InputBegan:Connect(function(input, gpe)    
09    if gpe then return end
10 
11    if input.KeyCode == Enum.KeyCode.Q and not deb then
12        deb = true
13 
14        dHum.WalkSpeed = 0
15        dHum.JumpPower = 0
16 
17        local v = Instance.new("LinearVelocity", dHRP)
18        v.MaxForce = 99999999
19 
20        v.VectorVelocity = Vector3.new(0,10,0)
21 
22        game.Debris:AddItem(v,0.3)
23 
24        wait(5)
25        deb = false
26    end        
27end)

basically I add a linearvelocity to the dummy's HumanoidRootPart, and so i thought to myself "This should move the dummy upwards, right?"

Welp, i was not right, please help

You forgot to set Attachment0.

Also when setting an NPC's velocity, always do it in a server script. To achieve that, you must use a RemoteEvent. It must be parented to ReplicatedStorage and named DummyVelocity.

LocalScript in StarterPlayerScripts or StarterGui:

01local RS = game:GetService("ReplicatedStorage")
02local RE = RS:WaitForChild("DummyVelocity")
03local UIS = game:GetService("UserInputService")
04 
05UIS.InputBegan:Connect(function(input, gpe)    
06    if gpe then return end
07    if input.KeyCode == Enum.KeyCode.Q then
08        RE:FireServer()
09    end
10end)

Script inside the dummy's HumanoidRootPart.

01local dHRP = script.Parent
02local dummy = dHRP.Parent
03local dHum = dummy:FindFirstChildOfClass("Humanoid")
04 
05local RS = game:GetService("ReplicatedStorage")
06local RE = RS.DummyVelocity
07local Debris = game:GetService("Debris")
08local deb = false
09 
10RE.OnServerEvent:Connect(function()
11    if not deb then
12        deb = true
13 
14        dHum.WalkSpeed = 0
15        dHum.JumpPower = 0
16 
17        local v = Instance.new("LinearVelocity", dHRP)
18        local attach = Instance.new("Attachment", dHRP) -- solution
19        v.Attachment0 = attach -- solution
20        v.MaxForce = math.huge
21        v.VectorVelocity = Vector3.new(0, 10, 0)
22 
23        Debris:AddItem(v, 0.3)
24        Debris:AddItem(attach, 0.3)
25 
26        task.wait(5)
27        dHum.WalkSpeed = 16
28        dHum.JumpPower = 50
29        deb = false
30    end
31end)

it still did not work for some reason lolmarios2647 46 — 2y

Wdym I even tested it in studio myself. T3_MasterGamer 2189 — 2y

same bro, did not work. Where did you put the LocalScript? lolmarios2647 46 — 2y

I edited the answer. Just follow the instructions and it should work. T3_MasterGamer 2189 — 2y
