Motor6D does not work properly, bugging the animation

[jmicco]

So, I’m developing my weapon system, and I’ve gotten to the step of animating the weapons using animations I’ve made via the MoonAnimator 2 plugin, and taking advantage of the tool’s Motor6D.

The problem I’m experiencing, is that once I use the animation in game (e.g., idle in onEquip), it turns out different from the animation I made. Viewing well then from the explorer, the Motor6D connected to the Tool’s Handle, and the Character’s Right Arm, did not move at all, when I in the animation I made changed the Handle’s position and direction.

I guessed that the problem is the Motor6D, and I tried to find some solution on the Forum or even from other sources outside of Roblox, but I cannot find a way to solve this problem.

Below is some media regarding the problem, and a piece of code regarding Motor6D:

What I expect:

What I get:

(If you should not notice any differences, the Handle that was animated does not move. In fact, the left arm should be near the weapon accessory, and not under the barrel)

Propety of Motor6D:

Local Script where I manage the Animations and the Motor6D:

local function onEquip(Child: Instance)
    if Child:IsA("Tool") and Child:FindFirstChild("Handle") and Child:FindFirstChild("Animations") then
        local Animator : Animator = Character:WaitForChild("Humanoid").Animator
        
        CurrentTool = Child
        
        local Animations = CurrentTool.Animations
        local Handle = CurrentTool.Handle
        
        print(Handle.Parent.Name)
        
        Motor6D.Part0 = Character['Right Arm'] 
        Motor6D.Part1 = Handle
        
        AnimationTracks = {
            ["Idle"] = Animator:LoadAnimation(Animations.Idle),
            ["Reload"] = Animator:LoadAnimation(Animations.Reload),
            ["Equip"] = Animator:LoadAnimation(Animations.Equip),
            ["Shoot"] = Animator:LoadAnimation(Animations.Shoot)
        }
        
        if AnimationTracks then
            AnimationTracks["Idle"].Priority = Enum.AnimationPriority.Action
            AnimationTracks["Equip"].Priority = Enum.AnimationPriority.Action2
            
            Handle.Sounds.Equip:Play()
            AnimationTracks["Equip"]:Play()
            AnimationTracks["Equip"].Stopped:Wait()
            
            
            AnimationTracks["Idle"]:Play()
        end
    end
end

Server Script where I create the Motor6D

Server

local function createM6D(Character)
    local rightArm = Character:FindFirstChild("Right Arm")
    if not rightArm then
        warn("Right Arm not found in character")
        return
    end
    
    local existingHandle = rightArm:FindFirstChild("Handle")
    if existingHandle then
        existingHandle:Destroy()
    end
    
    local Motor6D = Instance.new("Motor6D")
    Motor6D.Name = "Handle"
    Motor6D.Parent = rightArm

    if rightArm:FindFirstChildWhichIsA("Motor6D") then
        Motor6D.C1 = CFrame.new(0, -0.200000048, 0.674999952, 1, 0, 0, 0, 0, -1, 0, 1, 0)
    end
end


Players.PlayerAdded:Connect(function(Player: Player)
    Player.CharacterAdded:Connect(function(Character)
        
--[[code stuff]]--
        
        createM6D(Character)

--[[code stuff]]--

Player.CharacterAppearanceLoaded:Connect(function(Character)
        
        createM6D(Character)
        
        for _, Child in Character:GetChildren() do
            if Child:IsA("Accessory") then
                local Handle = Child:FindFirstChild("Handle")
                if Handle then
                    Handle.CanQuery = false
                end
            end
        end
    end)
end)

I hope someone can answer me as soon as possible, and let me find a solution!

I think the problem lies in the “RightGrip” weld constraint, created automatically by roblox, which blocks the movement of the motor6d. I tried to simulate the situation in broad terms and I had the same problem, that is, the tool handle was not animated, after which I added a line to the script I made that disabled it and the animation worked well. Now I don’t know if I have understood the problem correctly and if this is actually the solution, I hope I have helped you. Make sure that Motor6d is set on the server.

game.Players.LocalPlayer.Character["Right Arm"]["RightGrip"].Enabled = false
