Raycasting is detecting terrain materials as 'plastic'?

hey guys, what’s up, :slight_smile: basically, I’ve been having a trouble… I am raycasting to check if player is driving trough terrain, but it always print plastic(material) when the hit part is terrain
code;

	local char = player.Character
	if (char) then
		local humRoot = char.HumanoidRootPart
		if (humRoot) then
			if (humRoot.Velocity.Magnitude <= 10) then
				return
			end
			local para = RaycastParams.new()
			para.FilterDescendantsInstances = {workspace.Terrain,workspace.Map}
			para.FilterType = Enum.RaycastFilterType.Whitelist
			local ray = workspace:Raycast(humRoot.Position,humRoot.CFrame.UpVector*-40,para)
			if (ray) then
				if (ray.Instance) then
					if (ray.Instance == workspace.Terrain) then
						print(ray.Instance.Material)
						if (settings.AllowedTerrain[ray.Instance.Material]) then
							if (respawners[player]) then
								respawners[player] = nil
							end
							return
						end
						if (respawners[player]) then
							return
						end
						print('set respawn')
						respawners[player] = os.time()
					end
				end
			else
				if (respawners[player]) then
					respawners[player] = nil
					return
				end
			end
		end
	end

Any idea?

It’s in a loop.

as far as I know, Plastic is not a material from terrain :flushed:

Interesting, I think a better place for this would be #platform-feedback:studio-bugs

I don’t think it’s a bug, it’s somehow printing plastic idk why

#5

it is either a bug, or you messed something up in your script with the “material” printing. This wouldn’t be efficient, but if you haven’t already, I recommend using if statements for the different materials it could be detecting. Example:

if material == “Grass” then
print(“Grass”)

#6

Terrain materials, as all materials have they own class in Enum.Materials
So, that won’t work

#7

Gotcha, I recommend still going to #platform-feedback:studio-bugs and getting it checked out. The worst thing that could happen is it not being a bug and you get help.

#8

Sure, but I can’t post there yet.

#9

Oof, good luck! I hope you get this solved.

Firstly, try this:
Go on concrete (A block, not terrain), what does it print?
Go on plastic, what does it print?
Please answer these and I think I can help.

I think the main issue is with terrain, but if it doesn’t work with normal parts than I think its something wrong with their script.

#12

hey, sure, well, nothing much, it prints the part as its meant to, and when you go to terrain, pip, it prints material’s plastic :gorilla:

I have no clue what’s causing this, maybe we can @ staff or something

If someone knows, please

help :smiley:

#14

Maybe try that. Maybe tell someone who has access to #platform-feedback:studio-bugs to post something about this there. Staff like to check out the Studio Bugs area quite a bit.

#15

I’m pretty sure this isn’t supposed to happen, I guess it’s a bug and you can’t do anything to fix it :man_shrugging:

#16

Hi, I hope what I say helps. I found a similar thread where someone was trying to print out the material but it also returned as plastic
https://devforum.roblox.com/t/detecting-the-material-of-terrain-with-a-touched-function/299830/3

In this post, a Roblox staff member suggested checking out Humanoid.FlootMaterial in the API reference. Heres the link to that: https://developer.roblox.com/en-us/api-reference/property/Humanoid/FloorMaterial

#17

Hey, I have to check what’s under a part… so that will be hard :frowning:

#18

Anyone knows any solution to this D:

#19

Try to visualize your rays by materializing them into short lifetime parts.

Or create a non-collision part to show the ray’s end position

(to debug)

#20

I don’t think I should try that… since, Instance == workspace.Terrain returns true so, hmm if it wasn’t the hitpart terrain, it wouldn’t return true
