我正在编写一个在Robocode中运行的机器人。我的代码目前正常运行,我的坦克运行就像我希望它运行和移动一样。唯一的问题是它在战斗中多次撞到墙上,每次发生都会失去健康。
我试图在run()方法中使用getX()和getY()与我的网格的长度和宽度,getBattleFieldWidth()和getBattleFieldHeight()来比较我的主题位置,但是,似乎没有用。我也试过把这个代码放在我的onScannedRobot()方法中,但是效果不好。我试图,当我的主体从墙的每一侧接近50个单位时,将我的主体的方向改变为平行于墙壁。但是,这还没有奏效。我也尝试过做同样的事情,但是反转了我的主题的方向,但这也不起作用。我已经在run()和onScannedRobot()方法中尝试了所有这些并且还没有成功。
我试图使用RoboWiki Wall Smoothing/Implementations page中描述的算法:简单迭代墙平滑(通过PEZ),快速墙平滑(通过Voidious),非迭代墙平滑(由David Alves)和非 - Iterative Wall Hugging(由Simonton提供),并且尚未占上风。
我正在使用Robocode V1.7.3.6来运行此代码。
如何在我的代码中添加墙面避免,或者最好是墙面平滑?这是我的代码:

答案 0 :(得分:0)
检测机器人何时会很快撞到墙壁,并改变你的路线(或向后行驶),如果是这样的话?
要检测附近的墙壁,您可能需要使用getX()
,getY()
检查机器人的当前位置,并将其与竞技场getBattlefieldWidth()
的高度和宽度进行比较,{{1} }。
要了解您是否正在开车,可以查看getBattlefieldHeight()
和getHeading()
的标志。
