Applyment of basketball board for decision making in player management

Abstract

Information technology development and its integration in all aspects of our social and economic life did not leave out the sports. Increasing professionalism and competition cause clubs to approach all their activities in more and more systematic way. Progress is especially visible in training and analyzing opponents' teams and players, i.e. scouting. Therefore a need arises for such a program package that would enable better knowledge regarding basketball tactics, action analyses and creation, review of video actions and printing reports, i.e. documenting all actions, results and remarks during the work. This program is used by national team of Serbia when preparing the games in all official and friendly matches. This paper describes design and realization of program package for analyzes, scouting and creating basketball actions. Graphic objects comprising the editor with their own drawing methods. To realize such editor it was necessary to realize a number of auxiliary methods as bitmaps operation (rotation, transparency, resizing, shrinking and widening by certain factors), methods for manipulation and drawing the actions (paths) assigned to players (drawing line with particular dots, calculating distances in pixels between dots, dividing lines in certain dots) as well as methods connected to analytic geometry (distance between the dot and the line, line crossing etc.). Basketball actions consist of phases with their own methods of drawing and animation. Animation is an iterative procedure where in every step, under certain conditions (speed, delay) players are moving from spot to spot obtained by "chopping up" the trajectory of the player.
