Why doesn't my bullet fly straight?

Asked Nov 12, 2014245 views3 answers

When I click, the bullet comes out all kinds of different ways. I don't know why it does this, but it does. I just want it to fly straight forward.

function fireBullet(d)
	local bullet = Instance.new("Part")
	bullet.FormFactor = "Custom"
	bullet.Size = Vector3.new(1.5, 0.35, 0.35)
	bullet.BrickColor = BrickColor.new("White")
	bullet.Position = tool.Handle.Position + (d * 5)
	bullet.Velocity = d * 125
	
	local s = script.RemoveBullet:Clone()
	s.Disabled = false
	s.Parent = bullet
	
	local force = Instance.new("BodyForce")
	force.force = Vector3.new(0, 25, 0)
	force.Parent = bullet
	
	bullet.Parent = game.Workspace
end

Neither of these answers are correct.

The direction it flies all depends on what you give the parameter d when you call the function. Since we don't have the code where the function is called, we cannot tell for sure what the problem is.

When I made guns, I usually correctly CFrame the bullet first,

--Point towards mouse
bullet.CFrame = CFrame.new(tool.Handle.CFrame.p, mouse.Hit.p)
--Point forwards from the handle
bullet.CFrame = CFrame.new(tool.Handle.CFrame.p)

then I make it fly forwards according to its lookVector. (where the part is "looking"; its Front Face.)

bullet.Velocity = bullet.CFrame.lookVector * 125

Since I do not know what d ends up standing for, I do not know specifically what you're doing wrong. However, I can tell you for sure that speed and BodyForces will not affect how straight the bullet flies.

bullet.Velocity = d * 125

should b like

bullet.Velocity = d * 400

the more you add to the last number, the faster it goes:)

What does speed have to do with it flying forward?

Now it makes this loud "OOF" sound when a player is shot and killed.

Try and change the numbers around to see if it is the bullet that causes the "OOF" or the environment.

You need to make the Force (0,100,0) That makes a perfectly stright shot.

So like this

function fireBullet(d)
    local bullet = Instance.new("Part")
    bullet.FormFactor = "Custom"
    bullet.Size = Vector3.new(1.5, 0.35, 0.35)
    bullet.BrickColor = BrickColor.new("White")
    bullet.Position = tool.Handle.Position + (d * 5)
    bullet.Velocity = d * 125

    local s = script.RemoveBullet:Clone()
    s.Disabled = false
    s.Parent = bullet

    local force = Instance.new("BodyForce")
    force.force = Vector3.new(0, 100, 0) --This makes it perfectly stright
    force.Parent = bullet

    bullet.Parent = game.Workspace
end

Now it goes straight upward.

Try putting it like (100,0,0) Or (0,0,100) See if that works, if it doesn't then I have nothing for you.
