在棒球競賽中，攔截、中繼轉傳、補位、助守補漏的觀念，是守備訓練中非常重要的一環。在本論文中，筆者設計並完成了一個用於棒球轉傳補位訓練用的動畫式運動戰術模擬平臺軟體，將棒球轉傳補位模式數位化，並且讓使用者能自由選擇擊球落點位置與「擊球狀態」、「出局數」、「壘上跑者」、「安打／接殺」四個場上情境，以動畫的方式呈現出棒球比賽中會發生的基本轉傳補位模式。將防守方和攻擊方的每個球員視為獨立的個體物件，使每個野手有自己的移動方式和轉傳補位的模式，以球場上的「球」連結各個物件的運作。利用本系統的動畫物件建構播放平臺，就很容易發展出其他競技運動的戰術輔助教學系統。

In the baseball games, the concepts of cut-off, relay, cover and back-up are several very important elements for the fielding training. In this paper, we design and implement an animation based sport tactical simulation platform for the baseball "relay and cut-off play" training. This software transfers the situations in the cut-off play into an object model, allows users to choose the ball fallen location in the ball field arbitrarily and to select four different scenario options. There are "hit status," "number of outs," "runners on bases," "hit or out," and simulates the playing steps by an animation after finishing the players' action decision making processes. Due to this system treats each player as an independent individual object, and generates the players' defense moving and base running paths as well as the ball throwing trajectories. Each object in the ball field is activated by the "ball object" after the pitcher has delivered. It'll be very easy to develop many other similar athletic tactics systems by using this animation assisted platform.
