Question

例如，我有一个脚本附着在火上，如果玩家离火势的距离更近，我想对他造成伤害。

public float fireDamageRange = 5;
public float fireDamage = 10;

private Vector3 origin;
private Vector3 direction;

void Update(){
    origin = transform.position;
    direction = transform.forward;

    RaycastHit fireHit;
    if (Physics.SphereCast(origin, fireDamageRange, direction, out fireHit) && fireHit.transform.gameObject.layer == LayerMask.NameToLayer("Player") && !makingDamage)
    {
        makingDamage = true;
        MakeDamage(fireHit);
        StartCoroutine(WaitToMakeDamage());
    }
}
IEnumerator WaitToMakeDamage()
{
    yield return new WaitForSecondsRealtime(0.2f);
    makingDamage = false;
}

脚本已附加到火上。仅当Player实际上离原点有fireDamageRange时，才返回true，而如果他靠近原点，则不返回。我在做什么错了？

Answer 1

只需计算玩家与火之间的距离，并检查其是否在射程范围内

使用Vector3.Distance()

可以轻松计算距离

public float fireDamageRange = 5;
public float fireDamage = 10;
public GameObject player; // the player

private Vector3 origin;
private Vector3 direction;

void Update(){
    float distance = Vector3.Distance(player.transform.position, transform.position);
    if (distance <= fireDamageRange)
    {
        // handle damage to the player
    }
}

如果object比某个值近，则返回true。 Unity中的（广播）
