EnemyAI沿Y轴反向旋转

当战旗熄灭,玩家进入敌人的战区后,我想在玩家移动时跟踪它,确保敌人的Z轴始终指向玩家。

当玩家进入战区时,敌人会自动将玩家标记为其目标,但在第一次开始战斗时,Z轴可能不会指向敌人的目标。我决定在战旗熄灭时从敌人的Z轴发射一条射线,并旋转敌人,直到射线与玩家相交,从而告诉我敌人的Z轴已正确对齐。

敌人总是有其当前目标的参考。我的想法是,一旦敌人最初发现其目标,它可以保存最近发现的位置,然后获取当前目标位置的增量。x和最后一个点位置。x如果增量为正,则向右旋转;如果增量为负,则向左旋转。

问题是:我的数学或逻辑一定有缺陷,因为尽管有时可行,但其他时候敌人会随机向相反方向旋转,射线投射基本上会走很长的路线,而不是预期的最短路线。代码如下。

//create ray from enemy position orgin and point it on the Z-Axis
    Ray ray = new Ray(CurrentEnemyTransform.position, CurrentEnemyTransform.forward);
    RaycastHit hit;

    if (Physics.Raycast(ray, out hit, 50f))
    {
        Debug.DrawLine(ray.origin, hit.point);

        //ray hits current enemy target
        if (hit.transform == CurrentTargetTransform)
        {
            //check if enemy has seen its target before while in this battle
            //or is it the first time
            if (enemy.hasTargetLastPosition)
                //replace old last seen position with most recent spotting
                enemy.ReplaceTargetLastPosition(hit.transform.position);
            //or add the first spotting of target while in this battle
            else enemy.AddTargetLastPosition(hit.transform.position);
        }
        //ray is not intersectiing with the enemy's current target so rotate to look for it
        if (hit.transform != CurrentTargetTransform)
        {
            //check if enemy has seen its target once before in battle
            if (enemy.hasTargetLastPosition)
            {
                //since last spotting has my target moved more to the left or right?
                if (enemy.targetLastPosition.value.x > CurrentTargetTransform.position.x)
                {
                    //rotate right
                    CurrentEnemyTransform.Rotate(-Vector3.up, 5f, Space.Self);
                }
                        //rotate left
                else CurrentEnemyTransform.Rotate(Vector3.up, 5f, Space.Self);
            }
            //never seen target yet during this battle so default rotation to right till you found it
            else CurrentEnemyTransform.Rotate(-Vector3.up, 5f, Space.Self);
        }
