I’m creating a minigun which fires bullets, the only issue with these bullets is that they use .Touched() which is something I want to avoid using. The reason why is quite simple actually, the .Touched() event is too slow to fire and since the bullets move incredibly fast (Which, in my calculation, 1000 Studs per second I think), the bullets sometimes doesn’t register that a humanoid has been hit and simply phases through them.
So what is a better choice of detecting if a bullet hits a humanoid without using .Touched(). Should I use Region3 or something like GetPartsInPart?
If you need bullet drop or bullet travel time, consider using fastcast! Otherwise, raycasting should do the trick for arcade-y style weapons. There are many videos and documentation of fastcast online
The documentation for fastcast goes over everything, but it can be a little uncomfortable to use at first just like any module. Here’s the link to the documentation.
Oh, so Fastcast is a module, right? So does that mean I can globally use Fastcast and don’t need to constantly clone the Fastcast module to each gun using physical projectiles?
GetPartBoundsInBox() is a good way of replacing .Touched()
local RunService = game:GetService("RunService")
local Hitbox = workspace:FindFirstChild("Hitbox")
-- Without OverlapParams.
RunService.Heartbeat:Connect(function(deltaTime)
if Hitbox then
local PartBoundsInBox = workspace:GetPartBoundsInBox(Hitbox.CFrame, Hitbox.Size)
for i, v in PartBoundsInBox do
if v.Parent:IsA("Model") and v.Parent:FindFirstChild("Humanoid") then
local Model = v.Parent
local Humanoid = Model:FindFirstChild("Humanoid")
if Model and Humanoid and Humanoid.Health ~= 0 then
Humanoid:TakeDamage(3)
end
end
end
end
end)
-- With OverlapParams.
local Params = OverlapParams.new()
local Filter = {workspace.ExamplePart} -- "ExamplePart" will be ignored even if it's in the hitbox.
Params.FilterType = Enum.RaycastFilterType.Exclude
RunService.Heartbeat:Connect(function(deltaTime)
if Hitbox then
local PartBoundsInBox = workspace:GetPartBoundsInBox(Hitbox.CFrame, Hitbox.Size)
Params.FilterDescendantsInstances = Filter -- Putting it inside of the connection will constantly refresh the filter, just in case if :AddToFilter() is used at any point.
for i, v in PartBoundsInBox do
if v.Parent:IsA("Model") and v.Parent:FindFirstChild("Humanoid") then
local Model = v.Parent
local Humanoid = Model:FindFirstChild("Humanoid")
if Model and Humanoid and Humanoid.Health ~= 0 then
Humanoid:TakeDamage(3)
end
end
end
end
end)
Well, idk if I correctly placed the lines of code correctly since it didn’t work. Should I increase the size of the bullet?
local Tool = script.Parent
local FireEvent = Tool:WaitForChild("LaazerTime")
--//Functionality
FireEvent.OnServerEvent:Connect(function(Plr,MousePOS)
local Bullet = Instance.new("Part",workspace.Debris)
game:GetService("Debris"):AddItem(Bullet,5)
Bullet.Size = Vector3.new(0.5, 0.5, 0.5)
Bullet.CanCollide = false
Bullet.CastShadow = false
Bullet:SetNetworkOwner(Plr)
--Pos
Bullet.Position = Tool.FirePart.Position
Bullet.CFrame = CFrame.new(Tool.FirePart.Position,MousePOS)
--Moving Bullet
Bullet.Velocity = CFrame.new(Tool.FirePart.Position,MousePOS).LookVector * 1000
local AntiGrav = Instance.new("BodyForce")
AntiGrav.Force = Vector3.new(0, workspace.Gravity * Bullet:GetMass(), 0)
AntiGrav.Parent = Bullet
--Damaging
game:GetService("RunService").Heartbeat:Connect(function(deltaTime)
local PartBoundsInBox = workspace:GetPartBoundsInBox(Bullet.CFrame,Bullet.Size)
for i,v in pairs(PartBoundsInBox) do
if v:IsA("Model") and v.Parent:FindFirstChild("Humanoid") then
local Model = v.Parent
local Humanoid = Model:WaitForChild("Humanoid")
if Model and Humanoid and Humanoid.Health ~= 0 then
Humanoid:TakeDamage(6)
Bullet:Destroy()
end
end
end
end)
end)
I guess it does work, the only issue is that I want the bullets to disappear after hitting a humanoid, I tried doing Bullet:Destroy(), although it appears to didn’t work.
EDIT: Nvm, using Debris seems to work. Although, I think the bullets need to be reworked a bit, but it’s okay. Thanks!
