I am currently making a laser beam script (without using a tool) and I am trying to find the best way to visualize a ray.
This is what I have currently
What I am trying to achieve (without the tool)
Whole Script:
local UserInputService = game:GetService("UserInputService")
local hole = script.Parent:WaitForChild("RightArmWeld").Piece
local debris = game:GetService("Debris")
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local nweld = script.Parent.Torso['Right Shoulder']
local arm = script.Parent:WaitForChild("Right Arm")
local animation = script:WaitForChild("animation")
local hum = script.Parent:FindFirstChildWhichIsA("Humanoid")
local anim = hum:LoadAnimation(animation)
local lookvector = hole.CFrame.LookVector
oldC0 = nweld.C0
nweld.CurrentAngle = 0
nweld.DesiredAngle = 0
nweld.MaxVelocity = 0
local equipped = false
UserInputService.InputBegan:Connect(function(input,gameProccesedEvent)
if input.KeyCode == Enum.KeyCode.E and not gameProccesedEvent then
equipped = true
while equipped do
anim:Play()
local tframe = script.Parent.Torso.CFrame
tframe = tframe + tframe:vectorToWorldSpace(Vector3.new(1, 0.5, 0))
local taim = mouse.Hit.p -( tframe.p )
nweld.C0 = (CFrame.new(Vector3.new(),tframe:vectorToObjectSpace(taim))*CFrame.Angles(0,math.pi/2,0))+Vector3.new( 1, 0.5, 0 )
ray = Ray.new(hole.Position, (hole.CFrame.lookVector).unit*500,100,false)
wait()
end
end
end)
UserInputService.InputEnded:Connect(function(input,gameProccesedEvent)
if input.KeyCode == Enum.KeyCode.E then
equipped = false
nweld.MaxVelocity = .15
nweld.C0 =oldC0
anim:Stop()
end
end)
Simplified Script:
local hole = script.Parent:WaitForChild("RightArmWeld").Piece -- hole is a part welded to the right arm
ray = Ray.new(hole.Position, (hole.CFrame.lookVector).unit*500,100,false)
Any help would be greatly appreciated as I am not good at raycasting.
Roblox has actually made a very good tutorial on raycasting, and you can check it out here. At the link, check out the dropdown “Calculating Direction From an Origin and Destination” which I am sure answers your question. Keep in mind this tutorial uses the new “RaycastParams” system!
to fix the repeating I tried putting the ray out of the loop but it didn’t update the position then I tried putting just the CFrame in the loop but nothing changed.
I’ll try making it myself in Studio. But first, I have a question, was the laser beam intended to always be there or appear only when a player clicks to shoot or something like that?
If it would always be there, then welding a part to the hand seems to be a good option.
Sorry for the late reply but basically the laser beam continuously shoots when a player holds down the button “E”. The reason I welded a part to the hand is because I am welding another different part to the hand as sort of a “prop”. This is all in a local script in StarterCharacterScripts. I know it is only local but I intend on making a remote event once it works locally for convenience.
Is this what you wanted? I apologize for the lag robloxapp-20200812-1555409.wmv (817.9 KB)
PS-I’m sorry that you have to download it. I’m actually new to the DevForum, could you tell me how you uploaded the previous videos.
Yes this is what I am looking for. In regards to your other question… To upload a video you go to the upload button then hit choose files and select your video file.
lasers.LaserBeam is a premade part. I made it’s X and Y value very thin, and all I had to change was the Z value for the length. I used the length of the ray for this.
Then, I found the middle point of the ray and used it as the part’s position.
Finally, I used the direction of the ray as the direction of the part.
As a side note if anyone is trying to recreate this use a massless part stored in ReplicatedStorage and clone it or else whenever you aim at the sky you get pushed under the ground.
then hit choose files and select your video file.
