How do i use collection service?

[TafareWoomy (picklepicolo)]

I heard colletion service can be used to decrease the load of the server, and instead apply one script into parts with the collection tag, im trying to make a script whereas each of these parts (obstacles) when touched will explode the player on impact and it doesnt seem to work, does anyone know why this is happening?

You’re using CollectionService correctly but the syntax isn’t written correctly.

That’s why some words are underlined red.

Try this:

local CS = game:GetService("CollectionService")

for i, model in pairs(CS:GetTagged("Obstacle")) do
    model.Touched:Connect(function(hit)
        if hit.Parent:FindFirstChild("Humanoid") then
            local Bomb = Instance.new("Explosion")
            Bomb.BlastPressure = 100000
            Bomb.BlastRadius = 10
            Bomb.Position = model.Position
            Bomb.Parent = model
        end
    end)
end
