我认为这很简单,但是由于某些原因,我无法弄清楚。我的玩家周围有4个子GameObject,每个都有它自己的对撞机。我需要能够根据角色移动的方向启用和禁用子GameObjects。因此,如果玩家向右移动,则将禁用顶部和底部对撞机,而仅使右侧对撞机处于活动状态。如果玩家向上移动,则将禁用“左”,“右”和“底部”对撞机,仅留下“顶部”对撞机。这与其他两个方向的原理相同。但是由于某种原因,我的代码可同时用于左右方向,但是当我的角色向上或向下移动时,它将禁用除左对撞机之外的所有内容。我可以帮忙吗?这是我的代码:
public BasicNPCPrototype NPCPrototype;
private bool nearNPC = false;
public bool facingRight;
public bool facingUp;
public GameObject RightCollider;
public GameObject LeftCollider;
public GameObject TopCollider;
public GameObject BottomCollider;
// Use this for initialization
protected override void Start()
{
base.Start();
}
// Update is called once per frame
protected override void Update()
{
// Call the GetInput Function
GetInput();
// Call the CheckIfNear function
CheckIfNear();
// Call the CheckDirection function
CheckDirection();
// Call the DisableInteractionColliders function
DisableInteractionColliders();
base.Update();
}
void GetInput()
{
if(playerActive)
{
direction = Vector2.zero;
// Get the horizontal Axis and put in the X value of "direction"
direction.x = Input.GetAxisRaw("Horizontal");
// Get the Vertical Axis and put in the Y value of "direction"
direction.y = Input.GetAxisRaw("Vertical");
}
}
// Look at our movement direction and decide which way were facing
void CheckDirection()
{
if (direction.x > 0)
{
facingRight = true;
facingUp = false;
}
else if (direction.x < 0)
{
facingRight = false;
facingUp = false;
}
if (direction.y > 0) // && !facingRight)
{
facingUp = true;
facingRight = false;
}
else if (direction.y < 0) // && !facingRight)
{
facingUp = false;
facingRight = false;
}
}
// Look at what direction the Player is facing and disable/enable the correct colliders to account for it
void DisableInteractionColliders()
{
// WIP
if(facingRight)
{
RightCollider.SetActive(true);
LeftCollider.SetActive(false);
TopCollider.SetActive(false);
BottomCollider.SetActive(false);
} else if(!facingRight)
{
LeftCollider.SetActive(true);
RightCollider.SetActive(false);
TopCollider.SetActive(false);
BottomCollider.SetActive(false);
}
else if(facingUp)
{
TopCollider.SetActive(true);
RightCollider.SetActive(false);
LeftCollider.SetActive(false);
BottomCollider.SetActive(false);
} else if(!facingUp)
{
BottomCollider.SetActive(true);
RightCollider.SetActive(false);
LeftCollider.SetActive(false);
TopCollider.SetActive(false);
}
}

忽略CheckIfNear();调用更新功能,这是为了将来的计划,但当前为空。
答案 0 :(得分:2)
if(facingRight)
{
RightCollider.SetActive(true);
LeftCollider.SetActive(false);
TopCollider.SetActive(false);
BottomCollider.SetActive(false);
}
else if(!facingRight)
{
LeftCollider.SetActive(true);
RightCollider.SetActive(false);
TopCollider.SetActive(false);
BottomCollider.SetActive(false);
}
else if(facingUp)
{
TopCollider.SetActive(true);
RightCollider.SetActive(false);
LeftCollider.SetActive(false);
BottomCollider.SetActive(false);
}
else if(!facingUp)
{
BottomCollider.SetActive(true);
RightCollider.SetActive(false);
LeftCollider.SetActive(false);
TopCollider.SetActive(false);
}
faceingRight为True或False。这意味着您的第一对if语句(if(facingRight)
和if(!facingRight)
)始终为true,因此您的代码将永远不会到达第三个if语句,并且永远不会使用变量FaceingUp。
如果我是我,我将分配一个整数来存储方向,并使用开关选择对撞机。像这样:
int dir = 0;
void CheckDirection()
{
if (direction.x > 0)
{
dir = 1;
}
else if (direction.x < 0)
{
dir = 2;
}
if (direction.y > 0)
{
dir = 3;
}
else if (direction.y < 0)
{
dir = 4;
}
}
。
void DisableInteractionColliders()
{
LeftCollider.SetActive(false);
RightCollider.SetActive(false);
TopCollider.SetActive(false);
BottomCollider.SetActive(false);
switch(dir)
{
case 1: RightCollider.SetActive(true);
break;
case 2: LeftCollider.SetActive(true);
break;
case 3: TopCollider.SetActive(true);
break;
case 4: BottomCollider.SetActive(true);
break;
default: break;
}
}
