While loops doing what they need to multiple times?

Asked by

In my game, I am working on adding a Poison status effect, I have two while loops doing two different things; one is counting down the venom value when it is more than 0, and the other is removing the player's health as long as the value is above 0. The problem is, the loops start doing their function multiple times. For example, the while loop that is supposed to be counting the venom value down while it is above 0 will work fine for the first loop, but then the loop starts stalking on top of itself, and won't even stop when it is at 0. Instead, it counts down like this: 10, 9, 7, 3, -5, and then stops at -5. I have no idea why this is happening, help would be appreciated.

char.charactervalues.Venom.Changed:Connect(function()
    if char.charactervalues.Venom.Value > 0 then
        char.Torso.Poison.Enabled = true
        while char.charactervalues.Venom.Value ~= 0 do
            char.Humanoid.Health -= 3
            wait(0.8)
        end
    else 
        char.Torso.Poison.Enabled = false
    end
end)

char.charactervalues.Venom.Changed:Connect(function()
    if char.charactervalues.Venom.Value > 0 then
        while char.charactervalues.Venom.Value ~= 0 do
            wait(1)
            char.charactervalues.Venom.Value -= 1
        end
    end
end)

The way :Connect() functions work, is that each time the event triggers (in this case, the venom value), it starts a new function running the code. So, when your while loop is running, it is changing the venom value, and stacking new loops on top, causing it to behave very weirdly. A simple fix for this is a debounce value. Changed code:

debounce = false

char.charactervalues.Venom.Changed:Connect(function()
    if debounce == false then
        debounce = true
        if char.charactervalues.Venom.Value > 0 then
            char.Torso.Poison.Enabled = true
            while char.charactervalues.Venom.Value >= 0 do
                char.Humanoid.Health -= 3
                wait(0.8)
            end
        else
            char.Torso.Poison.Enabled = false
        end
        debounce = false
    end
end)

char.charactervalues.Venom.Changed:Connect(function()
    if debounce == false then
        if char.charactervalues.Venom.Value > 0 then
            while char.charactervalues.Venom.Value >= 0 do
                wait(1)
                char.charactervalues.Venom.Value -= 1
            end
        end
    end
end)
