Finding a certain value in an array with an unknown order

[1Joeb (joe)]

I am using :GetTouchingParts(), and I am trying to check to see if a ball is still touching a brick every .1 seconds.

There is more than one part touching the brick. I am assigning the ball a variable earlier in the script. How do I find the ball in the array?

This reply to your previous post about this is still valid. It is the most efficient way to check if an array contains a certain part.

Check if a part is still touching another part after touched event is called

local main_part = ... -- the main part local concerned_part = ... -- the part you want to know is touching the main part local touching_parts = main_part:GetTouchingParts() for i=1,#touching_parts do local part = touching_parts[i] if part == concerned_part then print("the concerned part is touching the main part") return true end end Darkmist is correct, it only works with CanCollide true parts. If you’re checking parts with either CanCollide == false, it will not …

When you say you are assigning the ball a variable, do you mean that you are doing something like:

local Ball = workspace.Ball

Then you can try this:

function Main()
    while wait(0.1) do
        local IsTouching = CheckParts(DesiredBrick)
        If IsTouching then
            print(“Touching”)
        else
            print(“Not touching”)
        end
    end
end

function CheckParts(DesiredBrick)
    local Found = false
    local TouchingParts = DesiredBrick:GetTouchingParts()
    for I, v in pairs(TouchingParts) do
        If v == Ball then
            Found = true
            break
        end
    end
    return Found
end

Sorry, I just had a few problems with it. But after looking back over the code, I actually understand how it works now.

I just found out why this wasn’t working. :GetTouchingParts only creates an array of intersecting parts. It should really be named :GetIntersectingParts .
