How to make the block change color and cause damage when touching

Help and Feedback Scripting Support
#1

I wanted a script for a barbed wire that when touched, take 25 damage and the color changes to red as indicative.

#2

You can simply use an onTouched event, and then take the Humanoid health, and minus 25 from the value.

Example:

part.Touched:Connect(function(touchedpart) --this will only work if it is a part, or another instance with the .Touched event.

    if touchedpart.Parent:FindFirstChild("Humanoid") then --a check to make sure the touched part is inside the character model 
    touchedpart.Parent:FindFirstChild("Humanoid"):TakeDamage(25) --damage the player
    end

end)

You can then also change the brick colour in the touched event to red. A similar thread can be found here:

A simple way to do that is by using the touched event. You would need a debounce variable set up so it will damage once, wait a bit, and then damage again.

In your touched event, check if whoever touched is a player or has a humanoid if you want it to also work for npcs, and if they are and the debounce is not a certain boolean, invert the boolean, change the color, damage them, wait a bit and set the debounce again so that way it can be reused

An example would be this script placed inside of the barbed wire

local part = script.Parent
local color = part.BrickColor

local deb = false

part.Touched:Connect(function(hit)
	local hum = hit.Parent:FindFirstChild("Humanoid")
	if deb or not hum then return end
	deb = true
	part.BrickColor = BrickColor.Red()
	hum:TakeDamage(25)
	wait(1)
	part.BrickColor = color
	deb = false
end)

Alternatively since the color changes, you can jsut check if the color is not red to continue instead of making a debounce variable, but this is to give an example of how debounces are typically done

db = true
color = script.Parent.Color
script.Parent.Touched:Connect(function(hit)
   humanoid = hit.Parent:FindFirstChildOfClass("Humanoid")
 if humanoid and db == true then
db  = false
humanoid.Health = humanoid.Health - 25
script.Parent.BrickColor = BrickColor.new("Really red")
wait(1)
db = true
script.Parent.Color = color
end
end)

Iā€™m getting an error: colorbrick is not a valid member of model workspace.structure.house

#6

The error is indicating that the script is unable to find something called ā€œcolorbrickā€ inside of ā€œworkspace.structure.houseā€.

Ensure that youā€™ve spelled and capitalized ā€œcolorbrickā€ the exact same way it appears in the explorer and that itā€™s placed inside of the correct place that youā€™re trying to reference in the script.

If thereā€™s the possibility that the ā€œcolorbrickā€ will not be in that place when it is referenced from the script, consider using FindFirstChild or WaitForChild inside of a conditional statement to ensure that it exists before continuing.

#7

I tried to do what you said and the error stopped, but the script simply doesnā€™t work when touching the barbed wire

#8

What code did you set up and where is the script located?

And what is the code in that script?

#11 
local part = game.Workspace:FindFirstChild("BarbedCoil", true)
local color = part.BrickColor

local deb = false

part.Touched:Connect(function(hit)
	local hum = hit.Parent:FindFirstChild("Humanoid")
	if deb or not hum then return end
	deb = true
	part.BrickColor = BrickColor.Red()
	hum:TakeDamage(25)
	wait(1)
	part.BrickColor = color
	deb = false
end)

Iā€™m using your script, but I made a small modification

#12

The issue is that you have multiple of those BarbedCoil things, so the code only works for one of them. are you getting any errors? Youā€™ll have to loop through the BarbedWire folder and put the touched event on all of them

#13

Iā€™m not getting any errors, the script just doesnā€™t work.

#14

Try this out so itā€™ll work for all the barbed coils

local parts = --Location of BarbedWire folder

for _,part in pairs(parts:GetChildren()) do
	local color = part.BrickColor
	part.Touched:Connect(function(hit)
		local hum = hit.Parent:FindFirstChild("Humanoid")
		if part.BrickColor == BrickColor.Red() or not hum then return end
		part.BrickColor = BrickColor.Red()
		hum:TakeDamage(25)
		wait(1)
		part.BrickColor = color
	end)
end
#15

An alternative, if your barb wire parts dont contain anything inside them is union. So union the parts together and connect the single touched event to it.

#16

Iā€™m getting another error: BrickColor is not a valid member of mesh

#17

Did you reference the correct folder? What is your code right now?

#18 
local parts = game.Workspace:FindFirstChild("BarbedCoil")

	for _,part in pairs(parts:GetChildren()) do
	local color = part.BrickColor
	part.Touched:Connect(function(hit)
		local hum = hit.Parent:FindFirstChild("Humanoid")
		if part.BrickColor == BrickColor.Red() or not hum then return end
		part.BrickColor = BrickColor.Red()
		hum:TakeDamage(25)
		wait(1)
		part.BrickColor = color
	end)
end

Reference the BarbedWire Model, not the BarbedCoil
