How to make a wow like mob target system?

Asked 151 views2 answers

Hi, I'm trying to make a mob/npc/creature/whatever you want to call it targeting system, basically when you click on something that has the target circle as a child, it the circle would become visible and when you click away from the thing or clicked on another thing that had a target circle as a child it would switch to that one.

I've tried to attempt this by myself but after countless tears of rage have been shed I decided that maybe I should stop metaphorically bashing my head against a wall and ask for help.

---This is my attempt---- don't laugh at me...

----------------------------------------------------------------------

local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()


local function target()

if  Mouse.Target.Parent:FindFirstChild("Target") then
	Mouse.Target.Parent:FindFirstChild("Target").Transparency = 0

	return Mouse.Target.Parent:FindFirstChild("Target")
end

end


local function untarget()
	local targeted = target()
if targeted == nil then
			Mouse.Target.Parent:FindFirstChild("Target").Transparency = 1
end
end


Mouse.Button1Down:Connect(untarget)

Hello, here is a quick example I made for you.

local selected

for _,v in pairs(workspace:GetChildren()) do
	if (v:FindFirstChild("ClickDetector") ~= nil) then --use a folder so you don't need this
		v.ClickDetector.MouseClick:Connect(function()
			if selected ~= nil then
				unselect()
			end
			doselect(v)
		end)
	end
end

function unselect()
	selected.Color = Color3.new(163,162,165)
	selected = nil	
end

function doselect(part)
	selected = part
	selected.Color = Color3.new(0,200,0)
end

local selected you declare the selected variable, which will be the currently selected entity or whatever

for _,v in pairs(workspace:GetChildren()) do this is pretty much just a way to loop through the children (not descendants) of workspace, you might change that to a folder which contains your entities. I like to use _, v, you can think of it as key, value, but in a loop like this key is always an index number, so we can ignore that.

You don't necessarily need the next line if you're using a folder and 100% sure you'll only have entities in there.

Moving on.

	v.ClickDetector.MouseClick:Connect(function()
		if selected ~= nil then
			unselect()
		end
		doselect(v)
	end)

...

function unselect()
	selected.Color = Color3.new(163,162,165) -- replace
	selected = nil	
end

function doselect(part)
	selected = part
	selected.Color = Color3.new(0,200,0) -- replace
end

So this is possible because when you call Connect it doesn't just pause execution until the MouseClick function is called, so you can actually do this in a loop for multiple instances.

Then, we check if there is a currently selected entity, and if there is, we call unselect. Then we select the new one.

This could be simplified however I feel like it's easier to understand this way.

Hello,

This is a short explanation; maybe use click Detectors in the parts and when clicked parent the Circle to the part?. Make sure to parent the parts in a folder in Workspace. To Get the circle back from the old part what you can do is wrap the if statement in a pairs loop like below,

Code Example, Parenting Circle to clicked Part.

script.Parent.ClickDetector.MouseButton1Click:Connect(function()
	for _,Instance in pairs(game.Workspace.Folder:GetChildren) do
		if Instance:FindFirstChild("Target") ~= nil then
				Instance.Target.Parent = script.Parent
		end
	end
end)

I hope your head and the wall you banged your head with recover soon....lol

I managed to make it so that when you click on a "NPC" the green circle becomes visible using your method however I'm not certain how to go about the second part which would be moving it from one "NPC" to another.
