title: Timer event to increase the value of a variable
body: <p>I'm working on a very basic program where I want a ball to follow a parabolic curve. My idea is to set a timer to tick with a certain interval and set the time as an variable which I use in my equation which will also be my x-value.</p>
  
  <p>I've created an event timer_Tick. How can I increase the value of X each time the timer ticks?</p>
