我在 Unity 中创建了一扇打开和关闭的门。我可以通过打电话打开那扇门Interact()
.
现在我想创建一扇始终远离玩家打开的门。就像酒吧的门一样。如果玩家在房间前面,门就会旋转到房间,如果玩家在房间里,门就会旋转出去。
目前我创建了一个布尔值opensAwayFromPlayer
。如果这是真的,则开门时目标旋转应该是固定的。
[SerializeField]
private Vector3 targetRotation; // rotation angles
[SerializeField]
private float duration; // rotation speed
[SerializeField]
private bool closeAgain; // close the door again?
[SerializeField]
private float waitInterval; // close the door after x seconds
[SerializeField]
private Vector3 pivotPosition; // Vector3 of the pivot
[SerializeField]
private bool opensAwayFromPlayer; // door can open both directions
[SerializeField]
private Transform playerTransform; // Player Object
private Vector3 defaultRotation; // store the rotation when starting the game
private bool isActive = false;
Transform doorPivot; // the pivot point to rotate around
private void Start()
{
doorPivot = new GameObject().transform; // create pivot
doorPivot.position = pivotPosition; // place the pivot before parenting!
transform.SetParent(doorPivot); // make the door being a child of the pivot
defaultRotation = doorPivot.eulerAngles;
}
private IEnumerator DoorRotation()
{
if (isActive)
yield break;
isActive = true;
float counter = 0;
Vector3 defaultAngles = doorPivot.eulerAngles;
Vector3 openRotation = transform.eulerAngles + targetRotation;
while (counter < duration)
{
counter += Time.deltaTime;
LerpDoor(defaultAngles, openRotation, counter); // open the door
yield return null;
}
if (!closeAgain)
Destroy(this);
yield return new WaitForSeconds(waitInterval); // wait some seconds
while (counter > 0)
{
counter -= Time.deltaTime;
LerpDoor(defaultAngles, openRotation, counter); // close the door
yield return null;
}
isActive = false;
}
private void LerpDoor(Vector3 defaultAngles, Vector3 targetRotation, float counter)
{
doorPivot.eulerAngles = Vector3.Lerp(defaultAngles, targetRotation, counter / duration);
}
private bool PlayerIsBehindDoor() // is the player in front of or behind the door?
{
Vector3 doorTransformDirection = transform.TransformDirection(Vector3.forward); // door direction
Vector3 playerTransformDirection = playerTransform.position - transform.position; // player direction
return Vector3.Dot(doorTransformDirection, playerTransformDirection) < 0; // return player is in front or behind the door
}
public void Interact() // start the rotation
{
StartCoroutine(DoorRotation());
}
正如你在这里看到的
if (opensAwayFromPlayer) // door can open both directions?
{
if (PlayerIsBehindDoor()) // Player is behind the door? (in the room)
{
// openRotation = ; // open to the other direction
// closeRotation = ; // close / back to the default rotation
}
}
我不知道如何计算它的不同旋转。仅将旋转设置为负值是行不通的。
当我将门向另一个方向旋转 90 度时,它没有向后旋转,而是向后旋转 270 度,同时保持另一个方向。
