I just finished a gun and everything works fine, until you move. As soon as you take a step forward, the bullets stop getting propelled forward. My script is kinda lengthy but I'll post it anyways.

tool = script.Parent
player = game.Players.LocalPlayer
mouse = player:GetMouse()
ammo = script.Parent.Ammo
storedammo = script.Parent.StoredAmmo
maxammo = script.Parent.MaxAmmo
enabled = true

function shoot()
if ammo.Value > 1 and enabled == true then
enable = false
firing = true

fire()
end
end

function createBullet()
bullet = Instance.new("Part",Workspace)
bullet.BrickColor = BrickColor.new("Bright blue")
bullet.Reflectance = 0.1
bullet.Transparency = 0.15
bullet.CanCollide = false
bullet.Anchored = false
bullet.FormFactor = "Custom"
bullet.Size = Vector3.new(0.2,0.4,0.2)
bullet.BottomSurface = "Smooth"
bullet.TopSurface = "Smooth"
bullet.CFrame = tool.Barrel.CFrame
--bullet.CFrame = CFrame.new(bullet.Position,mouse.Hit.p)

tag = Instance.new("StringValue",bullet)
tag.Name = "Creator"
tag.Value = player.Name

newscript = script.Parent.Damage:Clone()
newscript.Parent = bullet
newscript.Disabled = false

mesh = Instance.new("SpecialMesh",bullet)
mesh.MeshType = "Head"
mesh.Scale = Vector3.new(0.6,1,0.6)

light = Instance.new("PointLight",bullet)
light.Color = Color3.new(0,115,255)
light.Range = 1
light.Shadows = true

f = Instance.new("BodyForce",bullet)
f.force = Vector3.new(0,bullet:GetMass() * 197, 0)

game.Debris:AddItem(bullet,2)
end

function burst(v)
for i = 1,3 do
createBullet()
local hum = player.Character:FindFirstChild("Humanoid")
local head = player.Character:FindFirstChild("Head")
if hum and head then
v = (hum.TargetPoint - head.Position).unit
end
bullet.Velocity = v *100
wait(.1)
end
end

function fire()

repeat
burst()
ammo.Value = ammo.Value - 3
wait(.5)

until firing == false or ammo.Value == 0
end

function stop()
firing = false
end


tool.Activated:connect(shoot)
tool.Deactivated:connect(stop)

Try changing:

bullet.Size = Vector3.new(0.2,0.4,0.2)
bullet.BottomSurface = "Smooth"
bullet.TopSurface = "Smooth"
bullet.CFrame = tool.Barrel.CFrame
--bullet.CFrame = CFrame.new(bullet.Position,mouse.Hit.p)

to:

bullet.Size = Vector3.new(0.2,0.4,0.2)
bullet.BottomSurface = "Smooth"
bullet.TopSurface = "Smooth"
bullet.CFrame = tool.Barrel.CFrame+tool.Barrel.CFrame.lookVector*10--lower 10 if your barrel is shorter.
--bullet.CFrame = CFrame.new(bullet.Position,mouse.Hit.p)

Doesn't that just put it in front of the barrel?

yes, i believe the problem is that the bullet is getting stuck in the barrel/touching the character in some way.

Of course i could be wrong, i just did a quick scan through your code.

The bullets should be CanCollide = false. Would it still do that?

One the gun, make a tip part at the very tip of the mussle thingy.

Then whenever you make a new bullet here's how you CFrame it correctly:

bullet.CFrame = CFrame.new(gun.Hit.CFrame.p + (gun.Hit.CFrame.lookVector * 2), mouse.Hit.p)

@rosenburger

Could you explain the gun.Hit part? Is that supposed to be a part in the tool?

Oh actually I made a mistake sorry let me re write the code for you

bullet.CFrame = CFrame.new(gun.Tip.CFrame.p + (gun.Tip.CFrame.lookVector * 2), mouse.Hit.p)

So you need to make a part on your gun right infront of the mussle or barrel or whatever, it can be transparent it doesn't matter. Also make bullets and the gun's cancollide property set to false.

If you need further explaining on how it works I can help. Keep in mind this could be a logical error. You might have set up the code in a way it doesn't work after you move.
