Hello, I've been trying for a long time now but I've found nothing that helps, How do I use :ScreenPointToRay? I'm trying to make a very customizable gun, but it's not working, The furthest I've gotten was creating a part at the cameras origin, but nothing else
But this didnt help, any help is Greatly appreciated, Thank you!
I have never heard of this API before in my life. Try this:
local Players = game:GetService("Players")
local player = Players.LocalPlayer
local mouse = Player:GetMouse()
local camera = workspace.CurrentCamera
local length = 500
local unitRay
local ray
game:GetService(RunService).RenderStepped:Connect(function()
unitRay = camera:ScreenPointToRay(mouse.X, mouse.Y) --idk if this will work but try this. Mouse.X and Mouse.Y is the mouse position on the screen. Since it's constantly moving, you, want to update this using RenderStepped
ray = Ray.new(unitRay.Origin, unitRay.Direction * length) -- x is where the ray starts, y is the direction times the length. You can change the origin to the camera if you want as well as the length
end)
these are the basics of what i know about rays
script.Parent.Activated:Connect(function()
local camera = workspace.CurrentCamera
local length = 500
local unitRay = camera:ScreenPointToRay(100, 100)
local player = game.Players.LocalPlayer
local ray = Ray.new(unitRay.Origin, unitRay.Direction * length)
-- above is from what i read on the wiki
local part = Instance.new("Part", workspace)
part.Name = "NewPart"
part.CFrame = unitRay --CFrame expected
end)

Script?
For guns you should be using :ViewportPointToRay
