Unity Player 正在向自己开枪

Question

我的游戏中有以下问题：

场景中有两个角色，他们可以互相射击。如图所示，在彼此前面附加了一个名为“SpawnBullet”的空游戏对象，它会生成弹丸。

问题在于名为“玩家 2”的游戏对象正在向自己射击，子弹正朝着他的方向飞去。即使我旋转 SpawnBullet。在播放器 1 中它工作正常。

我正在使用这个部分（从上面复制）拍摄：

//right click to shoot
        if (Input.GetMouseButtonDown(1))

            {
                //checks if the tile is available based on the line and column of the unit
                Tile tileAux = hit.transform.gameObject.GetComponent<Tile>();
                Jogador scriptJog = player.GetComponent<Jogador>();

                if (tileAux.TilePostion.x == scriptJog.GridPosition.x || tileAux.TilePostion.y == scriptJog.GridPosition.y)
                {
                    if (tileAux.TilePostion.x > scriptJog.GridPosition.x)
                        tileAux.TilePostion.x = 5;
                    else
                        tileAux.TilePostion.x = 0;

                    if (tileAux.TilePostion.y > scriptJog.GridPosition.y)

            }
        }

Answer 1

当您向子弹添加力时，您使用的是Vector3.forward。您需要改用transform.forward。

Vector3.forward 始终是一个常数 (0, 0, 1)。把它想象成你世界的前进方向。它永远不会改变。

transform.forward 但是会给出游戏对象（玩家）的前向方向。当您旋转播放器时，它的 transform.forward 会相应改变。

播放器 1 似乎工作正常的原因是因为它与 Vector3.forward 面对相同的方向。
