Projectile stays still?

I have been scripting a gun, and while doing so, after making the CFrame of the bullet slightly away from the weapon (to ensure no damage is taken to the player, and for effect), but doing so makes the bullet freeze. I have no idea on how to fix this, but I have isolated the area I think makes it do that. There is also no errors in the output, and the code after it works fine. (In a localscript)

print 'all is good'

local t = script.Parent
local h = t.Handle
local MaxAmmo = script.MaxAmmo
local Ammo = script.Ammo
local AmmoPerClip = script.AmmoPerClip
local s = t.Sight
local running = false
local aiming = false
local AmIEquipped = false

t.Equipped:connect(function()
    AmIEquipped = true
    local plr = game.Players:FindFirstChild(t.Parent.Name)
    local m = plr:GetMouse()
    m.Button1Down:connect(function() --shoot function
        if MaxAmmo.Value == 0 then
            print 'no ammo'
        else
            Ammo.Value = Ammo.Value - 1
            if Ammo == 0 then
                print 'reloading'
                local emag = Instance.new("Part", Workspace)
                emag.FormFactor = "Custom"
                emag.Size = Vector3.new(0.5, 0.8, 0.48)
                emag.Position = h.Position - Vector3.new(0, 1.5, 0)
                MaxAmmo = MaxAmmo - AmmoPerClip
                Ammo = AmmoPerClip
                wait(10)

You are only moving the bullet once, while you need it to move constantly. Use a coroutine:

function bM(b)
    while wait(0.01) do
        b.CFrame = h.CFrame * CFrame.new(0, 0, -3)
    end
end
bulletMove = coroutine.wrap(bM);
bulletMove(b); --Call this when you need the bullet to move

It seems to stick to the barrel and moves with it, but it doesn't go out and reach a target. lowvillan 10 — 10y

Nevermind, I fixed it. Thanks for your help. lowvillan 10 — 10y

Might it be line 41?

Replace line 41 with v.velocity = (m.Hit.p - h.CFrame.p).unit*50 and see if that helps, because the way you had it, the velocity would be the mouse's hit position, instead of the direction to the mouse's hit position.

You fixed it, nevermind. :) PsychoWaffle 10 — 10y
