How do I do this?

Help and Feedback Scripting Support
#1

I have a script that lets me know when the player presses E. But how would I make it so that when the player actually presses E, it throws something at the cursor. Like if you were to throw a grappling hook. I know when the player presses E. How and where do I even start?

I’ll watch it, thanks for the video!

This is very helpful, but I need it to go to my mouse cursor not just straight forward. How do I do that? Also is there any way to give the projectile gravity?

#5

I believe Player:GetMouse().Hit.p returns the position that your cursor is touching.
You can get that position and send an object to that position, or at least in its general direction

#6

This is the current script:

local event = script.Parent.EPressed
local replicatedStorage = game:GetService("ReplicatedStorage")
local HookModel = replicatedStorage.Hook

event.OnServerEvent:Connect(function(Player)
	print("Fired to script")
	local char = script.Parent
	local HookProjectile = HookModel:Clone("Hook", char)
	HookProjectile.Parent = workspace
	HookProjectile.Anchored = false
	HookProjectile.CanCollide = false
	HookProjectile.CFrame = char.HumanoidRootPart.CFrame
	
	
	local bv = Instance.new("BodyVelocity", HookProjectile)
	
	
	
	bv.MaxForce = Vector3.one * math.huge
	bv.Velocity = char.HumanoidRootPart.CFrame.LookVector * 40
	game.Debris:AddItem(HookProjectile, 2)
	
end)

I tried doing Player:GetMouse().Hit.p but it said “Attempt to index hit with nil”
(I removed the GetMouse() for now)

#7

Try doing local Mouse = player:GetMouse() and then doing local Hit = mouse.Hit.p

#8

Did this:

local event = script.Parent.EPressed
local replicatedStorage = game:GetService("ReplicatedStorage")
local HookModel = replicatedStorage.Hook.Union

event.OnServerEvent:Connect(function(Player)
	print("Fired to script")
	local char = script.Parent
	local HookProjectile = HookModel:Clone("Hook", char)
	HookProjectile.Parent = workspace
	HookProjectile.Anchored = false
	HookProjectile.CanCollide = false
	HookProjectile.CFrame = char.HumanoidRootPart.CFrame
	
	
	local bv = Instance.new("BodyVelocity", HookProjectile)
	local Mouse = Player:GetMouse()
	local Hit = Mouse.Hit.p

	bv.MaxForce = Vector3.one * math.huge
	bv.Velocity = Hit * 50
	--bv.Velocity = char.HumanoidRootPart.CFrame.LookVector * 20
	game.Debris:AddItem(HookProjectile, 2)
	
end)

And still getting the error: Attempt to index nil with “Hit”

#9

It could be an issue with using a normal instead of local script. Can you try getting the position using Player:GetMouse() and hit on the local script and then sending that through the remote event to the normal script?

#10

Did that and now it says:
“attempt to perform arithmetic (mul) on instance and number.”

script:

local event = script.Parent.EPressed
local replicatedStorage = game:GetService("ReplicatedStorage")
local HookModel = replicatedStorage.Hook.Union

event.OnServerEvent:Connect(function(Player, Hit)
	print("Fired to script")
	local char = script.Parent
	local HookProjectile = HookModel:Clone("Hook", char)
	HookProjectile.Parent = workspace
	HookProjectile.Anchored = false
	HookProjectile.CanCollide = false
	HookProjectile.CFrame = char.HumanoidRootPart.CFrame
	
	
	local bv = Instance.new("BodyVelocity", HookProjectile)
	

	bv.MaxForce = Vector3.one * math.huge
	bv.Velocity = Hit * 50
	
	--bv.Velocity = char.HumanoidRootPart.CFrame.LookVector * 20
	game.Debris:AddItem(HookProjectile, 2)
	
end)

local script:

local uis = game:GetService("UserInputService")
local DB = false

uis.InputBegan:Connect(function(input, istyping)
	if istyping then return end
		if input.KeyCode == Enum.KeyCode.E then
		if DB == false then
			DB = true
			print("Pressed E")
			local Player = game.Players.LocalPlayer
			local Mouse = Player:GetMouse()
			local Hit = Mouse.Hit.Position
			script.Parent.EPressed:FireServer(Player, Hit)
			
			wait(1)
			DB = false
		end
	end
end)
#11

Try doing
bv.Velocity = tonumber(Hit) * 50

#12

still getting the same stupid error.

#13

Fixed it, instead of using bv’s and all that I decided to use CFrames, it probably works better as a CFrame for my future plans anyway.
