Need help on NPC touch event

Help and Feedback Scripting Support
#1

Hello, I am currently working on a Tower Defense like game and i’m trying to make it so that when a zombie touches a certain part my base loses health. The health is a intValue and i’m making a touch event for it. Everytime the zombie touches the part, it loses health. The problem is that it doesn’t, each zombie has a intValue inside of them saying “Enemy” and the number it supposed to damage my base. However, the touch event doesn’t work. Here is my script:

script.Parent.Touched:Connect(function(hit)
	if hit and hit.Parent:FindFirstChild("Enemy") then
		local enemy = hit.Parent:FindFirstChild("Enemy")
		local health = game.ReplicatedStorage.Health
		health.Value -= enemy.Value
	end
end)

Is there any errors sent to console, and FindFirstChild will only get the instance, you need to check the value perhaps?

I also noticed -= whats this suppose to mean?

#3

value1 -= value2 Is just an abbreviation for value1 = value1 - value2.

Anyways, if there were to be any problems it’d be with the if statement. Is enemy inside of the enemy model? Is it a value or the humanoid itself? Other than that the game may not be finding the health value but that’s less than likely. Try using game:GetService("ReplicatedStorage").Health instead.

The first solution would be @op to actually check the values of these values to see if they don’t come back nil or any other errors, basic debugging techniques.

#5

Yes the enemy value is inside of the model. I will try the using game getservice to get replicatedstorage

For some reason, when I modified the code for me to walk on the part it detected me walking but when I tried it for the zombies it detected nothing and the zombies were on the part that had the touch event.

Hey guys I fixed the issue, for some reason the “can touch” setting on the zombies were turned off and i just turned it back on. This took me a whole day to realize lol.
