How to play a motor 6D animation?

#1

Hi, I made a gun reload animation with a Motor6D but I am struggling to play it, I followed tutorials but they did not work. Another question I also have is would it be on the client or server side?

I am unsure of how you would do this using the new Animator | Roblox Creator Documentation object, as I learned it using the Humanoid | Roblox Creator Documentation method. However, because this is now depreciated you should learn it using the Animator object. Using Animations | Roblox Creator Documentation is what you’ll want to read to achieve this.

loca sine =  0

local rightarmc0 = CFrame.new(-.5,0,0) * CFrame.Angles(math.rad(0),math.rad(90),math.rad(0))

while wait() do
      sine = sine + 1
      ArmMotor6D.C0 = Clerp(ArmMotor6D.C0,rightarmc0 * CFrame.new() * CFrame.Angles(math.rad(0),math.rad(sine/10),math.rad(0)),1)
end

am using CFrameLerp in my animations

#4

I am very confused as to what this script does?

#5

u can use in looped animations

#6

but u should know CFrame and CFrame.Angles

#7

yeah but how would I implement this in my script?

	mouse.Button1Down:Connect(function()
		if gun.Ammo.Value > 0 then
			Event:FireServer(gun.Handle.Position,gun.Handle.Orientation, mouse.Hit.p)
			shotSound:Play()
			gun.Ammo.Value = gun.Ammo.Value - 1
		else	
			local reloadDebouce = gun.reloadDebouce
			if reloadDebouce.Value == false then
				reloadDebouce.Value = true
				-- I want to play ani here
				reload:play()
				reload.Ended:Wait()
				gun.Ammo.Value = 6
				reloadDebouce.Value = false
			end	
		end
	end)

of course you can, just learn CFrames

#9

I don’t think Cframes have something to do with motor6d animations

#10

How did you do it with the Humanoid?

#11

With the humanoid you just had to do something like this:

local animation = Instance.new("Animation")
animation.AnimationId = "rbxassetid://" .. animationId -- the animation id

animation = humanoid:LoadAnimation(animation) -- returns an AnimationTrack object
animation:Play() -- play the loaded animation

Still. You should use the new way. It’s honestly pretty much the same and just adds an extra step, which is to find the Animator. It can be done like this:

local animator = humanoid:WaitForChild("Animator") -- the Animator for the humanoid

local animation = Instance.new("Animation")
animation.AnimationId = "rbxassetid://" .. animationId -- the animation id

animation = animator:LoadAnimation(animation) -- returns an AnimationTrack object ** we've replaced humanoid:LoadAnimation with animator:LoadAnimation
animation:Play() -- play the loaded animation
