java怎么把子弹数组成圆形

<code class="java">double cx = 0;  // 圆心 x 坐标
double cy = 0;  // 圆心 y 坐标</code>

<code class="java">double radius = 100;  // 半径</code>

<code class="java">double angleStep = (2 * Math.PI) / bullets.length;  // 每个子弹之间的角度间隔</code>

<code class="java">for (int i = 0; i < bullets.length; i++) {
    double angle = angleStep * i;
    double x = cx + radius * Math.cos(angle);
    double y = cy + radius * Math.sin(angle);
    bullets[i].setX(x);
    bullets[i].setY(y);
}</code>

<code class="java">for (Bullet bullet : bullets) {
    bullet.update();
}</code>

<code class="java">import java.util.Arrays;

public class BulletCircle {
    public static void main(String[] args) {
        // 创建子弹数组
        Bullet[] bullets = new Bullet[10];
        for (int i = 0; i < bullets.length; i++) {
            bullets[i] = new Bullet();
        }

        // 计算圆心和半径
        double cx = 0;
        double cy = 0;
        double radius = 100;

        // 计算每个子弹的角度和位置
        double angleStep = (2 * Math.PI) / bullets.length;
        for (int i = 0; i < bullets.length; i++) {
            double angle = angleStep * i;
            double x = cx + radius * Math.cos(angle);
            double y = cy + radius * Math.sin(angle);
            bullets[i].setX(x);
            bullets[i].setY(y);
        }

        // 更新子弹位置
        for (Bullet bullet : bullets) {
            bullet.update();
        }

        // 打印子弹位置
        System.out.println(Arrays.toString(bullets));
    }

    private static class Bullet {
        private double x;
        private double y;

        public void setX(double x) {
            this.x = x;
        }

        public void setY(double y) {
            this.y = y;
        }

        public void update() {
            // 更新子弹位置
        }
    }
