Variation of the Original Classic PONG game brought to Cody.
PONG 003 is a rectangular board (2000,1000) with reasonable velocities and precision paddle movement. Three Times the Fun with 3-Balls.Other Cody PONG Games: <a href = "http://www.mathworks.com/matlabcentral/cody/problems/1257-pong-001-player-vs-wall-4-lives-interactive-download">PONG 001</a> and <a href = "http://www.mathworks.com/matlabcentral/cody/problems/1276-pong-002-rectangle-interactive-download-easier-play">PONG 002</a><img src = "https://sites.google.com/site/razapor/matlab_cody/PONG3_300.jpg">Attempt to keep the balls alive against a Wall. The balls speeds up on every hit. When all have been missed the next round restarts the balls at new locations. The start locations and sequences are purely deterministic. Movement of the paddle are max up/down steps of -1 to 1 (effective delta 25) or no move. Partial paddle moves allowed. The Balls do not interact with each other.Paddle center is provided and paddle covers +/- 50 units.
The field is rectangular at 2000 by 1000 with 3 walls and the lower left corner being (0,0)To aid in development of your routine, a PONG_Interactive_003c.m file that creates a solver script and video has been posted at <a href = "https://sites.google.com/site/razapor/matlab_cody/PONG_Interactive_003c.m">PONG_Interactive_003c.m</a>. (Right click, 'save link as'). The routine creates a PONG_003_solver.m script from the interactive play. The script demonstrates Interactivity, figure/KeyPressFcn, listdlg, and VideoWriter.<a href = "https://sites.google.com/site/razapor/matlab_cody/PONG_003_video_89.mp4">3-Ball PONG Demo Video</a> MP4 (Rt Click, Open in New Tab)Inputs: (paddle,ball)<pre> paddle = 500 ; %Paddle Center on the Y-axis, Paddle is +/- 50 from center

New variable " balls" vs prior ball. ball(2) would find the x position of the second ball. balls(5) would find y of second ball.
