java坦克大戰教程

1. java的坦克大戰程序

java.lang.NoClassDefFoundError: Hstank2 (wrong name:HsTank2)

找不到類Hstank2,確定你的包路徑跟實際放置的文件夾路徑相同，類名與引用處相同。
這應該是個極低級的錯誤。

3. java 編寫坦克大戰

需要看你的tank的draw方法里的內容代碼和碰撞檢測代碼。

一般二維碰撞檢測基本都是以單位格，也就是坦克的大小格作為單位，提前一格判斷兩個方格是否交叉，如果交叉則在當前，也就是交叉後退後一格這個位置讓它停止當前方向的移動。

5. java swing坦克大戰，如何實現發子彈

創建子彈形狀，初始位置為坦克前方，使用循環在坦克朝向上坐標遞加或遞減，並重新繪制子彈。就能模擬子彈的行進。判斷擊中，可以用形狀是否相交的函數。
