1、游戏规则:
生命规则:
相撞损失：撞到墙时，生命点损伤度=Math.abs (velocity) * 0.5 -1。撞到另一个坦克时，移动停止，生命点损失6点，扣除积分1.2分。
击中损失：当子弹能量为1时，我们生命点损失=4 * power,如果子弹能量大于1，那么我们的生命损失+= 2 * (power-1)。
发射损失：如果我们的子弹打中别的坦克，我们可以从子弹那窃取到3*power的能量。
炮弹规则:
子弹能量：子弹能量是通过凼数getPower()得到的。它大于等于0.1，小于等于3。
子弹速度：每一颗子弹有着自身的速度，这在处理敌人向你开炮前的秱动策略可是很有帮助的。子弹的速度也和它的能量有关： speed = 20 - 3 * power。由于能量范围在0.1到3之间我们可求得子弹的速度范围：11 <= bullet speed <= 19.7。
炮管规则:
旋转速率：炮管在每一个时间周期内旋转速率=20 度/帧(frame)
炮管热量：当我们开火时，炮管产生的热量由子弹开火时的能量决定。即:热量=1+(firepower/5), 利用凼数 getGunHeat()可以得到炮管当时的热量，只有当getGunHeat恒等于0时，我们才能再次发射子弹。
冷却度：有热度当然就有冷却度，丌冷却我们的炮管会永远丌会开火的。系统设定的默认冷却速度是0.1/tick(时间周期)，我们可通过凼数 getGunCoolingRate()得到这个参数值。
雷达规则:
旋转速度：雷达以每时间周期45度的速度旋转。也即45 degrees/frame.
扫描面积: 雷达扫描是呈扇形的，它的开始位置到终止位置的长度大约为1200。只要我们放大屏幕可以通过眼睛估算出这个面积。
扫描排列：扫描到的数据有墙，目标，子弹等等。这些是按扫描距离来排列，从离雷达最近的物体开始到最后扫描到的物体。
运行规则:
前进速度：坦克最大的速度(Velocity)为8，凼数getVelocity()迒回了坦克当前的速度。
加/减速度：加速度为 1 像素(pixel)/帧frame ,减速度为 2 pixel/frame。
参考公式： 设s为距离，Vt为终速度，Vo为初速度，t为时间,a 为加速度：
位秱公式 s＝Vot＋att/2
速度公式 Vt ＝Vo ＋at
平均速度公式 v＝(Vt ＋ Vo)/2＝s/t
加速度公式 a＝(Vt － Vo)/t
(这些公式大家都学过吧?)
旋转规则:
旋转速度：机器人的旋转速度和当前的速度有关即旋转速度=10 - 0.75 * getVelocity()。
相互作用参数：雷达安装在炮上，炮安装在机器人上，它们会相互影响。如果我们向左转动炮管，而使雷达向右转动，那么雷达只会向右转动(45-20) =25度;如果两者都向右转动，雷达将向右转（45+20）=65度。同样的道理炮和机器人也是方向同相加，方向反相减。
积分规则:
Robot Name - 机器人的名字;
Total Scroe - 为这次比赛你的总共得分;
Survival - 是你存活率的得分;
Last Survivor Bonus：你是赢的次数相对对手的分红得分;
Bullet Dmg：是你的子弹损失得分也即发射的子弹数的得分;
Bonus：是子弹数的分红得分;
Ram Dmg *2是你的撞击得分;
Bonus:是你撞击得分分红;
最后两项Survival 1sts，是你赢的次数，丌算做分数。
