Designing an FPS Framework: Beginner's guide

Yeah I don’t know why it spawns at 0,0,0, but it just does. Also, I used 60 velocity, like you did in your gun, but it moves way faster than your gun. Also reloading is already kind of simple, so I could probably do it myself.

That’s because I forgot to do dt * 60. I updated the script but I didn’t update the video.

Here is what I said in Part 2:

I printed the position of the bullet, spawns at 0,0,0. I did some extra testing, but nothing else important came up.

Do this also, this way we know if the bullet is spawning to actually positioning to the right position.

And also this.

I did print the barrels position, it’s fine. I modified the module to set the bullets position to the barrel, it works, but after 5-7 seconds, the bullet disappears. The bullet’s position isn’t 0,0,0 anymore, even when the bullet doesn’t appear.

Could you make a video showing this or instead make the game public so I can see the problem myself

It’s a local file, I will publish a game in a second…

game link ^

This is the output of me shooting:


There is no bullets.

Try and set the velocity to like 5, 60 may be too fast and also I noticed that the Y axis is going around -600…?

I think they’re spawning underground. When I go into first person, the bullets go away.
Also, if possible, could you provide an rbxm file of the module script for part 1?

When ingame could you check if the gun is welded properly, and also may I see the LocalHandler?

Unfortunately, No. I already provided the source code below. I don’t want people to gain nothing out of my tutorial (also another reason I don’t use code blocks). Sorry!

3: That’s alright, it’s just hard to see the module in a small image.

Are you modifying the barrel’s position in another script? because the barrel’s position is sometimes going into the negatives…?

module:



local MainModule = {}

function MainModule.Update(viewmodel, dt)
	viewmodel.HumanoidRootPart.CFrame = workspace.Camera.CFrame
end

function MainModule.weldgun(gun)
	local Main = gun.GunComponets.Handle

	for i,v in ipairs(gun:GetDescendants()) do
		if v:IsA("BasePart") and v ~= Main then
			local newMotor = Instance.new("Motor6D")
			newMotor.Name = v.Name
			newMotor.Part0 = Main
			newMotor.Part1 = v
			newMotor.C0 = newMotor.Part0.CFrame:inverse() * newMotor.Part1.CFrame
			newMotor.Parent = Main
		end
	end
end

function MainModule.equip(viewmodel, gun, hold)
	local GunHandle = gun.GunComponets.Handle
	local HRP_Motor6D = viewmodel:WaitForChild("HumanoidRootPart").Handle

	gun.Parent = viewmodel
	HRP_Motor6D.Part1 = GunHandle

	local Hold = viewmodel.AnimationController:LoadAnimation(hold)
	Hold:Play()
end

function MainModule.cast(gun,endposition,velocity)
	local GunBarrel = gun.GunComponets:WaitForChild("Barrel")

	local Bullet = Instance.new("Part")
	Bullet.Size = Vector3.new(1,1,5)
	Bullet.Anchored = true
	Bullet.CanCollide = false
	Bullet.Color = Color3.new(255,255,255)
	Bullet.Material = Enum.Material.Neon
	Bullet.Parent = workspace

	Bullet.CFrame = CFrame.new(Bullet.Position, endposition)
	Bullet.Position = GunBarrel.Position
	print(Bullet.Position)
	
	local Loop

	Loop = game:GetService("RunService").RenderStepped:Connect(function(dt)
		Bullet.CFrame *= CFrame.new(0, 0, -velocity * (dt * 5))
		if (Bullet.Position - GunBarrel.Position).magnitude > 1000 then
			Bullet:Destroy()
			Loop:Disconnect()
		end
	end)
end


return MainModule

Without Bullet.Position = GunBarrel.Position the bullet spawns at 0,0,0

Hm that’s weird could you try replacing your gun with my gun that I used in the tutorial:

groza.rbxm (8.7 KB)

You could also remove this Bullet.Position = GunBarrel.Position when testing with the gun I gave you

I misspelled “GunComponents” to “GunComponets” on some lines of code, so that might cause this issue. Also the same thing happens, the bullet spawns at 0,0,0

Uh, it should be CFrame.new(GunBarrel.Position, endposition). I honestly don’t know why I haven’t notice this earlier.

I tried that, never worked when I did that. I will try again, that was basically the entire reason I created a topic to fix this.

2 Likes

Well it should be that, doing Bullet.Position is just setting to its own position.

2 Likes

It shoots, unlike before when I tried that, but it spawns in a random position, not the barrel. It’s probably not random, but it’s confusing.

A video showing the problem would be much appreciated, also

Have you removed this line?
