Infinite RayCast?

Help and Feedback Scripting Support
#1

I’m trying to figure a way to make my Raycast Infinite in a direction -
The way it works at the moment is my:
When my ship chooses a Planet to warp to, the BodyGyro will adjust accordingly - Whilst doing so, a Raycast will be fired infront of the ship to verify whether or not it’s facing the required direction / Part, if so - then the warp commenses.

However, I’ve noticed that despite my effort my warp isn’t infinite and has a limited Range.
Below is a snippet of the BodyGyro’s turning and repeating. Does anybody have any suggestion?

			RayCastType.FilterDescendantsInstances = {FacePart}
			local RayCastResult = workspace:Raycast(System["Exterior"].PrimaryPart.CFrame.p, (System["Exterior"].PrimaryPart.CFrame.LookVector * 99999999) * 250, RayCastType)
			
			local _i = 0
			repeat wait() 
				if Configuration["Status"].Value == "Idle" then break end
				if _i > 100 then
					Configuration["Status"].Value = "Idle"
					if FacePart then
						FacePart:Destroy()
					end
					return
				end
				_i = _i + 1
				print(_i)
				BodyMovers["BodyGyro"].CFrame = CFrame.new(System["Exterior"].PrimaryPart.CFrame.p, SavedDestination)
				RayCastResult = workspace:Raycast(System["Exterior"].PrimaryPart.CFrame.p, (System["Exterior"].PrimaryPart.CFrame.LookVector * 99999999) * 250, RayCastType)
			until RayCastResult

Due to engine limitations and performance reasons a single ray cast can’t be infinite.

Are you sure you need an infinitely long ray? There is surely a better way of doing this.

Hi, I’ve experimented with different methods - Currently this is my best.

Reason for this being Planets located far beyond the Ships current Location aren’t detected when selected - That’s why I added a max of repeats so if after 100 attempts, it breaks and doesn’t warp.

Though, Ideally I want Players to be able to travel to these ‘Out of Range’ Planets.

If I could literally answer your question completely disregarding performance then I would do it like this.

local cf = System.Exterior:GetPrimaryPartCFrame()
local result = workspace:Raycast(cf.Position, cf.LookVector*5000, RayCastType) -- ray has 5k limit length
local intersection = result and result.Position or cf.Position + cf.LookVector*5000

while true do
    if not result then
        result = workspace:Raycast(intersection, Vector3.new(0, 0, -5000))
        intersection = result and result.Position or intersection + Vector3.new(0, 0, -5000)
    end
    wait(1) -- idk
end

Code is untested but should be like that. Once more tho, almost certainly a better way of doing this. Not sure 100% how your project works so won’t assume anything.

Thanks, I’ve tried messing around with this code and cannot seem to get it to work.

Though, to note how my system works -
It uses Legacy BodyMovers and when changing the Direction of the initial Ship it is literally a BodyGyro that changes to look at the new required “Warp Point” position.

It then Raycast’s forward until said Warp Point is registered, from there it enables everything else.

Got it working!

EDIT2://
It’s working, just similarly to the prior method where it’s limited.
