Physics.OverlapSphereNonAlloc

パラメーター

戻り値

int Returns the amount of colliders stored into the results buffer.

説明

球に触れている/中にあるコライダーを演算し、与えたバッファに保存します。

Does not attempt to grow the buffer if it runs out of space. The length of the buffer is returned when the buffer is full. Like Physics.OverlapSphere, but generates no garbage. Additional resources: Physics.AllLayers.

public class ExampleClass : MonoBehaviour
{
    void ExplosionDamage(Vector3 center, float radius)
    {
        int maxColliders = 10;
        Collider[] hitColliders = new Collider[maxColliders];
        int numColliders = Physics.OverlapSphereNonAlloc(center, radius, hitColliders);
        for (int i = 0; i < numColliders; i++)
        {
            hitColliders[i].SendMessage("AddDamage");
        }
    }
}
