c# - 如何让 Unity 中的 AI 角色在玩家前往某个特定点的途中绕过玩家

Question

当我的玩家进入 AI 的距离内时，AI 将其状态更改为 Flee 并调用此函数：

void Flee()
    {
        inTransit = false; //this makes sure he gets to his destination before rerouting

        if(IsPlayerBlockingPath() && DistanceToTarget(player.position) < 10f)
        {
            PerpendicularMovement(HorizontalNormalToTarget(player.position));
        }
        else        
        {
            MoveTowardsTarget(enemyBase.position);
        }       
    }

我正在使用（我相信是）从 ai 到他的“enemyBase”的单位向量和从 ai 到玩家的单位向量的点积。如果它是一个介于 0.5 和 1 之间的值，那么这两个向量的方向相似，所以我们需要围绕玩家进行引导。然而，我的 AI 只在地图的某些部分绕着玩家而不是其他地方

float DistanceToTarget(Vector3 location)
    {
        return (transform.position - location).magnitude;
    }

bool IsPlayerBlockingPath()
    {
        Vector3 AIToPlayer = HorizontalNormalToTarget(player.position);
        Vector3 AIToEnemyBase = HorizontalNormalToTarget(enemyBase.position);

        float dotP = Vector3.Dot(AIToPlayer, AIToEnemyBase);
        if (dotP > blockTollerance) //blockTollerance is set to 0.1f
        {
            return true;
        }

        return false;
    }

void PerpendicularMovement(Vector3 perpToThis)
    {
        Vector3 perpDirection = Quaternion.Euler(0, 90, 0) * perpToThis;
        MoveTowardsTarget(perpDirection * perpMovementIncrement);
//I need him to move in this direction a bit further than he currently will
    }
