How to change the properties of all parts in a model at once?
Hello. I'm trying to make a script that while touched, turns the color of all the lights in a game red, and the point lights inside them red as well. I tried to use "GetDescendants" and "GetChildren", but they didn't seem to work. The light parts are all in a model called "lights" in Workspace. Is there even a correct way to change the properties of all parts in a model at once without having to address them all individually? Any help would be greatly appreciated. Thanks!
local lights = game.Workspace.lights:GetDescendants()
local part = script.Parent
local pointlights = lights:GetChildren():GetChildren("PointLight")
part.Touched:connect(function()
lights.BrickColor = BrickColor.new("Bright red")
pointlights.Color = Color3.new(1, 0.109804, 0.109804)
end)
script.Parent.TouchEnded:connect(function()
lights.BrickColor = BrickColor.new("Institutional white")
pointlights.Color = Color3.new(1, 1, 1)
end)

using a for loop, you can loop through all the descendants or children of an object
local lights = game.Workspace.lights
local part = script.Parent
part.Touched:connect(function()
for i, v in pairs(lights:GetDescendants()) do
if v:IsA("PointLight") then
v.Parent.BrickColor = BrickColor.new("Bright red")
v.Color = Color3.fromRGB(COLOR) -- this color is using RGB so copy and paste the color you want for it
end
end
end)
script.Parent.TouchEnded:connect(function()
for i, v in pairs(lights:GetDescendants()) do
if v:IsA("PointLight") then
v.Parent.BrickColor = BrickColor.new("Institutional white")
v.Color = Color3.fromRGB(COLOR) -- this color is using RGB so copy and paste the color you want for it
end
end
end)

Yes, there should be a proper way to do this, and by golly please do not manually setting all those light properties. Here is how I would personally set up code to follow
part.Touched:connect(function()
for i, v in pairs(lights:GetChildren()) do
v.BrickColor = BrickColor.new("Bright red")
for index, value in pairs(v:GetChildren()) do
value.Color = Color3.new(1,0.109804, .109804)
end
end
end)
part.TouchedEnded:connect(function()
for i, v in pairs(lights:GetChildren()) do
v.BrickColor = BrickColor.new("Institutional white")
for index, value in pairs(v:GetChildren()) do
value.Color = Color3.new(1,1,1)
end
end
end)
I believe you will come across an issue that I should address. Touched events and especially TouchEnded typically do not work how you want them. When a part stops moving on top of a another part, TouchedEnded fires. Doesn't matter if it "actually left" or not, this issue still occurs. I recommend looking up solutions to around this.
