I don’t know what to do this is getting on my nerves I spent 10 hours just trying to rotate a projectile when the character fires it but I don’t know how… Please, please help…

here’s the script:

projectile.CFrame = CFrame.lookAt(projectile, mouse.Hit)

good luck

#3

if the parts not anchored then do this

projectile.CFrame = CFrame.lookAt(projectile, mouse.Hit)

gyro = Instance.new("BodyGyro")
gyro.Parent = projectile
gyro.MaxTorque = Vector3.new(math.huge, math.huge, math.huge)
gyro .CFrame = CFrame.lookAt(projectile, mouse.Hit)
#4

Where would I put that? Or it doesn’t matter also what is mouse.hit that’s not on my script

#5

no mouse.Hit???
you cant make a functioning gun without that!

#6

Unless, your gun is not going to be controlled by the mouse.

#7

I don’t really know I’m trying to fix this where I was messing with a while ago so the position works it’s just the rotation it doesn’t move where the mouse is, or the camera I want it to rotate you can play test it in studio if you want and see what I mean

#8

you only have to rotate the projectile when setting its CFrame.

Projectile.CFrame = CFrame.new(SpawnPos) * CFrame.Angles(0, math.pi/2, math.pi/2)
#9

Here’s my solution for this, if the part isn’t anchored:

local turnSpeed = 2

game:GetService("RunService").RenderStepped:Connect(function(dt)
    projectile.CFrame *= CFrame.Angles(0, 0, math.rad(turnSpeed) * dt) -- assuming the projectiles lookvector is the direction it's moving
end)
#10

It’s not a local script it’s a normal script.

#11

Then use .Heartbeat. I misunderstood you for a second.

#12

That doesn’t work I don’t know why here’s the model

#13

you’re using a model? You cannot use this method with model, of course. use setpivot():

local turnSpeed = 2

game:GetService("RunService").Heartbeat:Connect(function(dt)
    projectile:SetPivot(projectile:GetPivot() * CFrame.Angles(0, 0, math.rad(turnSpeed) * dt)) -- assuming the projectiles lookvector is the direction it's moving
end)

try this

#14

no take the tool out of the model

#15

I don’t understand what that means?

#16

Okay, so I’ve provided the model if you could take the model and insert it in your game when u insert it the tool will be inside of a model, just put the tool in starterpack and you’ll see what I’m talking about how the arrows don’t rotate.

#17

I won’t insert anything into my game, but if you can send me images, and also clarify what type of instance you’re trying to rotate? A part or a model?

#18

it’s a part I was only talking about the model that I’ve provided.

I just want them to face the right way when the player clicks also I’m talking about the “arrows”

#20

Sorry, I forgot to apply the direction. It should work now

Projectile.CFrame = CFrame.lookAt(SpawnPos, SpawnPos + Direction) * CFrame.Angles(0, math.pi/2, math.pi/2)
