How do I detect parts better

I’ve been repeatedly reading this for 5 minutes and I still haven’t gotten a grasp on how I’ll do this :moyai:

#22 
-- RaycastParams can be reused and making it each time you use raycast, will cuase lag
local raycastParams = RaycastParams.new()
raycastParams.FilterDescendantsInstances = {plr.Character};
raycastParams.FilterType = Enum.RaycastFilterType.Blacklist;

local FinishedTiles = {};

local function Raycast(Origin, Direction)
	local raycastResult = workspace:Raycast(rayOrigin, rayDirection, raycastParams);

	if raycastResult then
		local hitPart = raycastResult.Instance;
		-- Check if the part resides in a folder, that it's fully visible, and not locked
		if hitPart:GetAttribute("Owner") == plr.PlayerValues.Attacking.Value then;
			plr.PlayerValues.Pixels.Value += 1;
			hitPart.Color = plr.PlayerValues.ColorValue.Value;
			hitPart:SetAttribute("Owner",plr.Name);
		end
	end
end

for _, Tile in pairs(workspace.Europe:GetChildren()) do
	if Tile:IsA("BasePart") and Tile:GetAttribute("Owner") == plr.Name and Tile:FindFirstChild("Done") == nil then
		local DoneValue = Instance.new("BoolValue");
		DoneValue .Name = "Done";
		DoneValue .Parent = v;
		table.insert("FinishedTiles", DoneValue);

		Raycast(Tile.Position, Vector3.new(0, 0, -0.3));
		Raycast(Tile.Position, Vector3.new(0, 0, 0.3));
		Raycast(Tile.Position, Vector3.new(-0.3, 0, 0));
		Raycast(Tile.Position, Vector3.new(0.3, 0, 0));
	end
end

for _, Value in pairs(FinishedTiles) do
	Value:Destroy();
end

what do i put here?

#24

put Origin, and Direction(UHHHH CHARACTER LIMIT)

#25

lol, which direction tho there are 4 directions that need to be shot

#26

you have to right

local raycastResult = workspace:Raycast(Origin, Direction, raycastParams);
#27

oh aight, are they just going to be nil?, like i’m going to have to activate it like this?
image

#28

what are you doing? is there more part where you need to do raycast?

#29

image
I’m already did the function right here

#30

yeah but what am i going to put in the brackets?
image

#31

why do you need to do more raycast? if you just want to learn then, the first parameter goes the Origin of the raycast, and the second one is the Direction of the raycast

#32

It’s a local function, how am I going to activate it?
image
what will i put for the variables of Origin and Direction? will it just be a nil object?

#33

wait nvm, i see it now it’s seperate, sorry. I am high i apologize for disturbing you i feel rlly stupid rn :woozy_face: :weary:

#34 
Raycast(Vector3.new(0, 0, 0), Vector3.new(1, 1, 1));

Really sorry, you can rest easy now thank you! i’ll start testing it.

for some reason the ray casts extends itself to like this any ideas why?
the size of each pixel is 0.6x0.6 studs

#37

you didn’t change the code at all? except the raycast part?

#38

I changed the code so that it doesn’t delete the parts, other than that, nothing i could think of

game.ReplicatedStorage:WaitForChild(script.Name).OnServerEvent:Connect(function(plr)
	-- RaycastParams can be reused and making it each time you use raycast, will cuase lag
	local raycastParams = RaycastParams.new()
	raycastParams.FilterDescendantsInstances = {plr.Character};
	raycastParams.FilterType = Enum.RaycastFilterType.Blacklist;

	local FinishedTiles = {};

	local function Raycast(Origin, Direction)
		local raycastResult = workspace:Raycast(Origin, Direction, raycastParams);

		if raycastResult then
			local hitPart = raycastResult.Instance;
			-- Check if the part resides in a folder, that it's fully visible, and not locked
			if hitPart:GetAttribute("Owner") == plr.PlayerValues.Attacking.Value then
				plr.PlayerValues.Pixels.Value += 1;
				hitPart.Color = plr.PlayerValues.ColorValue.Value;
				hitPart:SetAttribute("Owner",plr.Name);
			end
		end
	end

	for _, Tile in pairs(workspace.Europe:GetChildren()) do
		if Tile:IsA("BasePart") and Tile:GetAttribute("Owner") == plr.Name and Tile:FindFirstChild("Done") == nil then
			local DoneValue = Instance.new("BoolValue");
			DoneValue .Name = "Done";
			DoneValue .Parent = Tile;
			table.insert(FinishedTiles,Tile);

			Raycast(Tile.Position, Vector3.new(0, 0, -0.1));
			Raycast(Tile.Position, Vector3.new(0, 0, 0.1));
			Raycast(Tile.Position, Vector3.new(-0.1, 0, 0));
			Raycast(Tile.Position, Vector3.new(0.1, 0, 0));
		end
	end
	
	for i = 1,#FinishedTiles do
		table.remove(FinishedTiles,i)
	end
	
end)
#39

wait I thought you wanted to delete the BoolValue named Done?

#40

I changed it to 0.1 because of the bug
