Projectile doesn't exactly replicate to all clients

Help and Feedback Scripting Support
#1

My projectile doesn’t sync to all clients. When i shoot the projectile, it perfectly works on my local but when on the other client’s view, the projectile moves to its direction relative to their local mouse position.

here is my script that i put on a starter player as a replicator.

local Game = game --Local environment variables.
local Workspace = workspace
local ReplicatedStorage = Game:GetService("ReplicatedStorage")
local RemoteEvent = ReplicatedStorage:FindFirstChild("Remotes").SW_Rocket.SW_RocketFire or ReplicatedStorage:WaitForChild("Remotes").SW_Rocket.SW_RocketFire --RemoteEvent reference.
local fire = ReplicatedStorage:FindFirstChild("Remotes"):FindFirstChild("SW_Rocket").SW_Fire
local rocket = game:GetService("ReplicatedStorage"):FindFirstChild("Projectiles").SW_Projectiles.Fireballz
local blast = game:GetService("ReplicatedStorage"):FindFirstChild("Projectiles").SW_Projectiles.BlastExplosion
local db = false

local player = game:GetService("Players").LocalPlayer
local mouse = player:GetMouse()

local function OnRemoteFired(Handle,barrel) --RemoteEvent's 'fired' function.
	local newRocket = rocket:Clone()
	newRocket.BrickColor = BrickColor.new("Lime green")
	newRocket.CanCollide = false
	newRocket.CFrame = CFrame.new(barrel.Position,mouse.Hit.Position)
	newRocket.Parent = Workspace.ignore
	local newForce =  Instance.new("BodyVelocity")
	newForce.Parent = newRocket
	newForce.Velocity = (mouse.Hit.Position - barrel.Position).Unit*130
	newForce.MaxForce = Vector3.new("inf","inf","inf" )

end
RemoteEvent.OnClientEvent:Connect(OnRemoteFired)

you need to add reference to the player who shot the gun.

newRocket.CFrame = CFrame.new(barrel.Position,mouse.Hit.Position)

in the second argument, you are using the local player’s mouse, which is why “the projectile moves to its direction relative to their local mouse position.”

in other words, for the player that is going to shoot, you need to also send over the mouse data to the server, then from the server, send it to the clients, and use that specific mouse data to implement the projectile.

i tried your code but it everytime i hit the target it add 100 coins not only the shooter’s leaderstats but to all clients which is not what i had expected.

#4

can you send me what you are putting in?

#5

this is the code from serverscript service that give 100 gold to the player

fire.OnServerEvent:Connect(function(player,partHit)
	local damages = {["Torso"]= 40 ,["Head"] = 200 , ["Intersection"]= 35, ["Belly"]= 25, ["LShoulder"]= 19, ["RShoulder"]= 23, ["LeftFoot"]= 20, ["LeftHand"]= 20, ["LeftLowerArm"]= 21,["LeftLowerleg"]= 22,["LeftUpperArm"]= 21, ["LeftUpperLeg"]= 22,["RightFoot"]= 20,["RightHand"]= 20,["RightLowerArm"]= 21,["RightLowerLeg"]= 22,["RightUpperArm"]= 21,["RightUpperLeg"]= 22,["Union"]= 25, ["UpperTorso"] = 45}
	local Damage = 0
	for _, v in pairs(partHit) do
		if v.Parent:FindFirstChild("Monster") and v.Parent:FindFirstChild("Monster").Health > 0  and damages[v.Name] then
			local totalDamage = Damage + damages[v.Name]

			v.Parent:FindFirstChild("Monster").Health -= totalDamage
			player:FindFirstChild("leaderstats"):FindFirstChild("Gold").Value = player:FindFirstChild("leaderstats"):FindFirstChild("Gold").Value + totalDamage
			for i, value in pairs(v.Parent:FindFirstChild("Monster"):GetChildren()) do
				if value:IsA("ObjectValue") and value.Name 	== "creator" then
					value:Destroy()

				end
				local creator_Tag = Instance.new("ObjectValue")
				creator_Tag.Name = "creator"
				creator_Tag.Value = player
				debris:AddItem(creator_Tag,2)
				creator_Tag.Parent = value.Parent
			end
			--print(totalDamage)



		elseif v.Name == "Weakpoint" and v.Parent:FindFirstChild("Monster") and not v.Parent:FindFirstChild("Boss") and v.Parent:FindFirstChild("Monster").Health > 0  then
			local MonsterHealth = v.Parent:FindFirstChild("Monster").Health

			v.Parent:FindFirstChild("Monster").Health -= BusterMaxDamage

			player:FindFirstChild("leaderstats"):FindFirstChild("Gold").Value = player:FindFirstChild("leaderstats"):FindFirstChild("Gold").Value + BusterMaxDamage + 200
			for i, value in pairs(v.Parent:FindFirstChild("Monster"):GetChildren()) do
				if value:IsA("ObjectValue") and value.Name 	== "creator" then
					value:Destroy()

				end
				local creator_Tag = Instance.new("ObjectValue")
				creator_Tag.Name = "creator"
				creator_Tag.Value = player
				debris:AddItem(creator_Tag,2)
				creator_Tag.Parent = value.Parent
			end

			if MonsterHealth <= BusterMaxDamage then
				for i, value in pairs(v.Parent:FindFirstChild("Monster"):GetChildren()) do
					if value:IsA("ObjectValue") and value.Name 	== "creator" then
						value:Destroy()

					end
					local creator_Tag = Instance.new("ObjectValue")
					creator_Tag.Name = "creator"
					creator_Tag.Value = player
					debris:AddItem(creator_Tag,2)
					creator_Tag.Parent = value.Parent
				end
				--player:FindFirstChild("leaderstats"):FindFirstChild("Titan kill").Value = player:FindFirstChild("leaderstats"):FindFirstChild("Titan kill").Value + 1
				player:FindFirstChild("leaderstats"):FindFirstChild("Gold").Value = player:FindFirstChild("leaderstats"):FindFirstChild("Gold").Value + MonsterHealth - BusterMaxDamage
				player:FindFirstChild("PlayerGui"):FindFirstChild("ScreenGui").Frame.Visible = true
				player:FindFirstChild("PlayerGui"):FindFirstChild("ScreenGui").Frame.KillSFX:Play()
				print("play")
				delay(1, function()
					player:FindFirstChild("PlayerGui"):FindFirstChild("ScreenGui").Frame.Visible = false
				end)
			end
