Student – Help me with this

Hi Jan Montano

I hope you are very well. I’m looking forward to hear from you.

Actually I’ve added some code for infectious. I’d like you to help me in that. I’m still confused with it and I should submit the first coursework two weeks later.

Thanks

Hi Jan Montano

Thanks for your replying. I would like to provide me by your E-mail to keep in touch and I send to you some codes. The code which I posted is part of the code. There are other codes I have done.

Regards,

This is code what I have done for the first coursework. Hope it is clear.
I need to collaborate with someone.

using System.Collections; // For ArrayList

	public class AIPlayer : BasePlayer
	{
		PlayerWorldState myWorldState;

		ArrayList Lines = new ArrayList();

		public AIPlayer() : base ()
		{
			this.Name = "OneStepEvaluator";

			// Initialise the array of 8 lines
			Lines.Add(new Line(0,0,0,1,0,2)); // Vertical Line (0,0), (0,1), (0,2)
			Lines.Add(new Line(1,0,1,1,1,2)); // Vertical Line (1,0), (1,1), (1,2)

I have done some codes for the first coursework. I hope there is someone is able to help me in that.

Thanks
