User:Pedersen/Code Samples/RobocodeSG

Following are some examples of my code to support debugging with RobocodeSG.
First is an example of the code in use, followed by my wrapper for the swing graphics, and finally a structure for holding drawable line segments, mostly used for ad-hoc tests such as ensuring my movement projection looks right, or finding the difference in escape angles between an opponent going at a tangent or turning into the wave. -- Martin

This is from my WaveOutboundBank class, which maintains a list of waves that I've fired. The StaticPositionImpl constructor being used starts at the wave's origin and finds the point radius units away in the direction of the firing angle.

public void onPaint( Graphics2D console )
{
	long time = Host.singleton.getTurn();
	
	Iterator iterator = this.iterator();
	while( iterator.hasNext() )
	{
		CombatWave wave = ( CombatWave ) iterator.next();
		double radius1 = wave.getRadius( time - 1 );
		double radius2 = wave.getRadius( time     );
		double radius3 = wave.getRadius( time + 1 );
		console.setColor( Color.darkGray );
		GraphicalDebugger.singleton.drawRing( console, wave, radius1 );
		GraphicalDebugger.singleton.drawRing( console, wave, radius2 );
		GraphicalDebugger.singleton.drawRing( console, wave, radius3 );
		Iterator firingAngleIterator = wave.getFiringAngleIterator();
		while( firingAngleIterator.hasNext() )
		{
			FiringAngle firingAngle = ( FiringAngle ) firingAngleIterator.next();
			StaticPosition point1 = new StaticPositionImpl( wave, firingAngle.getFiringAngle(), radius1 );
			StaticPosition point2 = new StaticPositionImpl( wave, firingAngle.getFiringAngle(), radius2 );
			StaticPosition point3 = new StaticPositionImpl( wave, firingAngle.getFiringAngle(), radius3 );
			console.setColor( Color.red );
			GraphicalDebugger.singleton.drawLine( console, point1, point2 );
			console.setColor( Color.yellow );
			GraphicalDebugger.singleton.drawLine( console, point2, point3 );
		}
	}
}

Thanks. It think i will have a busy evening --Loki
