Projectile drop has a weird bug

#1

So I have been working on a game in which you throw a snowball which includes drop. Now the thing is is that it works completely fine normally, but it drops way slower if I am moving to the left or backwards. I have absolutely no idea how to fix this so I would appreciate ideas or comments. Thanks!

Looks like it seems to work fine if you’re not moving, could we see le script that handles the snowball throwing?

#4 
local player = game.Players.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()
local hum = char:WaitForChild("Humanoid")

local RS = game:GetService("ReplicatedStorage")
local event = RS.Events:WaitForChild("SBThrow")
local UIS = game:GetService("UserInputService")

local debounce = false



local sound = RS.Sounds:WaitForChild("Throw")
local int = char:WaitForChild("Ammo")
local mouse = player:GetMouse()




local anim = RS.Animations:WaitForChild("Throw")
local animtrack = hum:LoadAnimation(anim)

UIS.InputBegan:Connect(function(input,isTyping)
	if isTyping then
		return
	
	
	elseif input.UserInputType == Enum.UserInputType.MouseButton1 and int.Value >= 1 and
		char.HumanoidRootPart.Anchored == false and debounce == false then
		
		int.Value = int.Value - 1
		sound:Play()
		event:FireServer(mouse.Hit)
		animtrack:Play()
		debounce = true
		
		
	    
		
		
		
		
	
	end	
end)

event.OnClientEvent:Connect(function()
	wait(0.5)
	debounce = false
	
end)```

May we see the RemoteEvent you havem, aka the OnServerEvent code for SBThrow

do you mean the localscript? or where its located

#7

The code for the OnServerEvent of SBThrow in a regular script since we can’t go off of the localscript

#8 
local RS = game:GetService("ReplicatedStorage")
local event = RS.Events:WaitForChild("SBThrow")
local UIS = game:GetService("UserInputService")
local snow = RS.Meshes:WaitForChild("Snowball")
local TweenService = game:GetService("TweenService")
local damage = 37
local debris = game:GetService("Debris")
local HitSound = RS.Sounds.Hit
event.OnServerEvent:Connect(function(player,md)

	
	local Snowball = snow:Clone()
	Snowball.CFrame = player.Character.RightHand.CFrame
	Snowball.CanCollide = false
	Snowball.Anchored = false
	Snowball.Parent = workspace
	
	
	

	local hitbox = Instance.new("Part")
	hitbox.Size = Vector3.new(3,3,3)
	hitbox.Anchored = false
	hitbox.Transparency = 1
	hitbox.CFrame = Snowball.CFrame
	hitbox.Parent = workspace
	hitbox.CanCollide = false
	hitbox.Massless = true
	

	local weld = Instance.new("ManualWeld")
	weld.Part0 = hitbox
	weld.Part1 = Snowball
	weld.Parent = weld.Part0
	 
	local char = player.Character
	local humrp = char.HumanoidRootPart
	
	Snowball:SetNetworkOwner(player)
	
	local velocity = Instance.new("BodyVelocity",Snowball)
	velocity.MaxForce = Vector3.new(1,1,1) * math.huge
	velocity.Velocity = md.LookVector * 150
	
	
	

	Snowball.Parent = workspace
	debris:AddItem(Snowball,5)
	
		hitbox.Touched:Connect(function(hit)
		local hitSFX = Instance.new("Sound",Snowball); hitSFX.SoundId = "rbxassetid://4518881974" 
		if hit:IsA("BasePart") then
			if not hit:IsDescendantOf(char)  then
				local Ehum = hit.Parent:FindFirstChild("Humanoid")
				if Ehum then
				Ehum:TakeDamage(damage)
				hitSFX:Play()
				hitbox:Destroy()
				wait()
				Snowball:Destroy()
				
				end
		
			end
		end
		
		wait(0.1)	
		spawn(function() 
			while wait(0.1) do
				velocity.Velocity = velocity.Velocity - Vector3.new(0,1,0)
			end
		end)
		
	end)	

	event:FireClient(player)
	
end)

lol i didnt realize i sent the localscript

Not sure how much it’ll help, but maybe you can use Unitray.Direction instead of Hit?

event:FireServer(mouse.UnitRay.Direction)

And in the OnServerEvent

velocity.Velocity = md * 150

UnitRay is jsut a 1 stud long Ray that is directed towards mouse.Hit, maybe you can use that instead?

#10

It does work just as well, but unfortunately, it still goes straight when I move left.

#11

you should put some server side checks or exploiters might use a script like this to spam snowballs

Potential Exploit 
local plr = game.Players.LocalPlayer
local rs = game:GetService("RunService")
local event = game.ReplicatedStorage.Events.SBThrow
local mouse = plr:GetMouse()

local firing = false

mouse.Button1Down:Connect(function()
firing = true
end)

mouse.Button1Up:Connect(function()
firing = false
end)

while rs.Heartbeat:Wait() do
if firing == true then
event:FireServer(mouse.Hit)
end
end
#12

Although I would agree, this is unrelated to the OP

Could you try using Mouse.Hit.Position?

#13

I’ve tried all of them but I have no idea why this is happening

#14

Your bullet drop function is inside the touched function for some reason

Heres what I imagine is happening:

  • When you are moving forwards the touch event is fired because it touches the player, as it is a stationary and easy to hit target
  • When you are strafing side to side, the snowball lags behind and consequently does not activate the bullet drop section of the script

Id reccomend moving the bullet drop section to after the event exits then reexamining what happens
