Question

我在如何在我的2d平台上实现A *寻路时遇到了一些困难。

基本上我现在拥有的是玩家后面的敌人动画精灵。问题是当敌人与障碍物（平台）发生碰撞时，它将一直停留在那里直到玩家移动。这是我现在的代码：

      physicsWorld.registerPhysicsConnector(new PhysicsConnector(this, bodyEnemy, true, false) {
    @Override
    public void onUpdate(float pSecondsElapsed) {
        super.onUpdate(pSecondsElapsed);

        double dx = Player.bodyPlayer.getWorldCenter().x - bodyEnemy.getWorldCenter().x;
        double dy = Player.bodyPlayer.getWorldCenter().y - bodyEnemy.getWorldCenter().y;
        double length = Math.sqrt(dx * dx + dy * dy);
        double accelerationX = dx / length;
        double accelerationY = dy / length;

        bodyEnemy.setTransform(new Vector2((bodyEnemy.getWorldCenter().x + ((float) accelerationX / 32)),
            (bodyEnemy.getWorldCenter().y + ((float) accelerationY / 32))), 0);
        float spd = selectedLevel * 0.1f;
        if (spd >= 1.0f)
            spd = 1.0f;

        if (Player.bodyPlayer.getWorldCenter().x - bodyEnemy.getWorldCenter().x < 0) {
            bodyEnemy.setLinearVelocity(new Vector2(bodyEnemy.getLinearVelocity().x, -spd));

            } else {
                bodyEnemy.setLinearVelocity(new Vector2(bodyEnemy.getLinearVelocity().x, spd));
            }

        if (Player.bodyPlayer.getWorldCenter().y - bodyEnemy.getWorldCenter().y < 0) {
            bodyEnemy.setLinearVelocity(new Vector2(bodyEnemy.getLinearVelocity().y, -spd));
            } else {
                bodyEnemy.setLinearVelocity(new Vector2(bodyEnemy.getLinearVelocity().y, spd / 2));
            }


    }
    });

如何让我的敌人找到绕过障碍物的方法，并继续追逐玩家？
