yieldBreak

API - pauses the script for x amount of seconds.

return function
    local x = 0;
    while x < 5000 do
    
        yield(); --yield works in combination with deltaTime
        
        if x > 30 then
            yieldBreak(); --causes this coroutine to close out immediately
        end
        
        --without yield, the application would freeze & be stuck in a loop.
        --until x is equal to 5000
        x = x + 1;
    end
    
    log('this will never be reached.');
end
