PhysicsScene.Raycast

パラメーター

戻り値

bool レイが任意のコライダーと交わる場合は true、それ以外は false

説明

Casts a ray, from point origin, in direction direction, of length maxDistance, against all colliders in the Scene.

You may optionally provide a LayerMask, to filter out any Colliders you aren't interested in generating collisions with. Specifying queryTriggerInteraction allows you to control whether or not Trigger colliders generate a hit, or whether to use the global Physics.queriesHitTriggers setting.

以下の例ではオブジェクトの現在位置から前方へ距離 10 ユニットのレイを投影するシンプルな Raycast を作成します。

using UnityEngine;

public class ExampleClass : MonoBehaviour
{
    void FixedUpdate()
    {
        Vector3 fwd = transform.TransformDirection(Vector3.forward);

        if (Physics.Raycast(transform.position, fwd, 10))
            print("There is something in front of the object!");
    }
}

This method generates no garbage.

using UnityEngine;
public class RaycastExample : MonoBehaviour
{
    void FixedUpdate()
    {
        RaycastHit hit;

        if (Physics.Raycast(transform.position, -Vector3.up, out hit))
            print("Found an object - distance: " + hit.distance);
    }
}
