Robocode Processing Loop

The order that Robocode runs is as follows:

1. Battle view is (re)painted
2. All robots execute their code until they take action (and then paused)
3. Time is updated (time = time + 1)
4. All bullets move and check for collisions
5. All robots move (heading, accelration, velocity, distance, in that order)
6. All robots perform scans (and collect team messages)
7. All robots are resumed to take new action
8. Each robot is processing its event queue

Time and distance measurements in Robocode

Time (t)	Robocode time is measured in "ticks". Each robot gets one turn per tick. 1 tick = 1 turn.
Distance Measurement	Robocode's units are basically measured in pixels, with two exceptions. First, all distances are measured with double precision, so you can actually move a fraction of a pixel. Second, Robocode automatically scales down battles to fit on the screen. In this case, the unit of distance is actually smaller than a pixel.
