You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? I’m working on a gun system, and I’m using raycasting to detect whether there is a part, and if there is, it changes the script so that I can’t shoot through walls, sometimes it just doesn’t work, and it also offsets the bullet to the left or right randomly, though it looks up every time if it does find a part.
I looked on the devforum, but didn’t really find anything, and I’m running out of options.
Here is the relevant code.
RemoteEventFire.OnServerEvent:Connect(function(plr, MouseClickPos, BulletPartSignifierPos, Damage, HeadShotDamage)
local function FireBullet()
local rayOrigin = BulletPartSignifierPos
local rayDirection = MouseClickPos
local raycastParams = RaycastParams.new()
raycastParams.FilterDescendantsInstances = {Parent.Parent.BulletPartSignifier, Parent}
raycastParams.FilterType = Enum.RaycastFilterType.Blacklist
local raycastResult = workspace:Raycast(rayOrigin, rayDirection, raycastParams)
if raycastResult then
for i, v in pairs(WorkspaceChildren) do
if raycastResult.Instance == v then
print("In Workspace!!!")
local bullet = Instance.new("Part")
bullet.Name = "Bullet"
bullet.CanCollide = false
bullet.Anchored = true
bullet.BrickColor = BrickColor.new("New Yeller")
bullet.Material = Enum.Material.Neon
bullet.Parent = workspace
local Center = (raycastResult.Position + BulletPartSignifierPos) / 2
bullet.Size = Vector3.new(0.01, 0.01, (BulletPartSignifierPos - raycastResult.Position).Magnitude)
bullet.CFrame = CFrame.lookAt(Center,raycastResult.Position)
if raycastResult.Instance.Parent:FindFirstChild("Humanoid") and raycastResult.Instance.Name == "Head" then
raycastResult.Instance.Parent:FindFirstChild("Humanoid"):TakeDamage(HeadShotDamage)
print("Humanoid")
elseif raycastResult.Instance.Parent:FindFirstChild("Humanoid") then
raycastResult.Instance.Parent:FindFirstChild("Humanoid"):TakeDamage(Damage)
print("Humanoid")
end
wait(0.05)
bullet:Destroy()
end
end
else
print("NotFoundPart")
local bullet = Instance.new("Part")
bullet.Name = "Bullet"
bullet.CanCollide = false
bullet.Anchored = true
bullet.BrickColor = BrickColor.new("New Yeller")
bullet.Material = Enum.Material.Neon
bullet.Parent = workspace
local Center = (MouseClickPos + BulletPartSignifierPos) / 2
bullet.Size = Vector3.new(0.01, 0.01, (BulletPartSignifierPos - MouseClickPos).Magnitude)
bullet.CFrame = CFrame.lookAt(Center, MouseClickPos)
bullet.Touched:Connect(function(hit)
if hit.Parent:FindFirstChild("Humanoid") and hit.Name == "Head" and not hit.Parent.Name == plr.Name then
hit.Parent:FindFirstChild("Humanoid"):TakeDamage(HeadShotDamage)
elseif hit.Parent:FindFirstChild("Humanoid") and not hit.Parent.Name == plr.Name then
hit.Parent:FindFirstChild("Humanoid"):TakeDamage(Damage)
end
end)
wait(0.05)
bullet:Destroy()
end
end
FireBullet()
end)
plr is the Player.
MouseClickPos is Mouse.Hit.P, the Vector3 location in the workspace.
BulletPartSignifierPos is the position of the part where I want the bullet to originate from,
Damage, HeadShotDamage (Just number values and have no real reference)
This is the client part for shooting.
Mouse.Button1Down:Connect(function()
LeftButtonReleased = false
if GunEquipped == true and Idle == false and OutOfAmmo == false and Firing == false and MuzzleBlast == true then
if AutomaticWeapon == true then
while true do
Firing = true
script.Shooting:Play()
RemoteEventFire:FireServer(Mouse.Hit.p, BulletPartSignifier.Position, Damage, HeadShotdamage)
MagAmmo = MagAmmo - 1
CurrentAmmoGUI.Text = MagAmmo
if MagAmmo <= 0 then
OutOfAmmo = true
end
wait(FireRate)
Firing = false
script.Shooting:Stop()
if LeftButtonReleased == true or OutOfAmmo == true or Idle == true then
break
end
end
elseif AutomaticWeapon == false then
Firing = true
script.Shooting:Play()
RemoteEventFire:FireServer(Mouse.Hit.p, BulletPartSignifier.Position, Damage, HeadShotdamage)
MagAmmo = MagAmmo - 1
CurrentAmmoGUI.Text = MagAmmo
if MagAmmo <= 0 then
OutOfAmmo = true
end
wait(FireRate)
Firing = false
script.Shooting:Stop()
end
end
end)
So I tested it, and it seems just to looking up and to the right, I click on the part sometimes, and it doesn’t return an instance, so I’m assuming it’s the ray, I likely need to modify the mouse position that I provided it to fix it, but is there anything I could do to fix it?
fidjsfujdsjufds It works! Okay, thank you. And then we have one other problem, damaging. I believe the problem is that when shooting Humanoids, it can only collide with the HumanoidRootPart, is this because CanCollide is turned on* for limbs? If so, I will change it with a character script.
When I damage a humanoid, it returns this and never anything else, so I’m assuming that is the reason.
But the problem I have is it doesn’t raycast properly sometimes, and so I keep that there as a safeguard/pre-caution, because if it doesn’t find anything, then it just won’t shoot at it.
Also i think its because the Ray is not extending, your mouse hit position might be a little behind what you do
try putting this in
local function FireBullet()
local rayOrigin = BulletPartSignifierPos
local rayDirection = ((MouseClickPos - rayOrigin).Unit) * 1000
--Unit sets the direction to do one stud
--Replace 1000 with the range you want
thanks, what fixed it was the mouse hit position was just shy of the actual target so it stopped before it hit, I made it so the Vector3 direction would be 1 stud, then you multiply it by the range you want.
