| origin | The starting point of the ray in world coordinates. |
| direction | Направление луча. |
| maxDistance | The max distance the ray should check for collisions. |
| layerMask | A Layer mask that is used to selectively ignore Colliders when casting a ray. |
| queryTriggerInteraction | Specifies whether this query should hit Triggers. |
bool @return True если луч пересекся хотя-бы с одним коллайдером,в ином случае - false.
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.
This example creates a simple Raycast, projecting forwards from the position of the object's current position, extending for 10 units.
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!"); } }
| origin | The starting point of the ray in world coordinates. |
| direction | Направление луча. |
| hitInfo | If true is returned, hitInfo will contain more information about where the collider was hit. (See Also: RaycastHit). |
| maxDistance | The max distance the ray should check for collisions. |
| layerMask | A Layer mask that is used to selectively ignore Colliders when casting a ray. |
| queryTriggerInteraction | Specifies whether this query should hit Triggers. |
bool @return True если луч пересекся хотя-бы с одним коллайдером,в ином случае - false.
Casts a ray, from point origin, in direction direction, of length maxDistance, against all colliders in the Scene.
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); } }
| origin | @param ray Начальная точка и направление луча. |
| direction | Направление луча. |
| raycastHits | The buffer to store the hits into. |
| maxDistance | The max distance the rayhit is allowed to be from the start of the ray. |
| layerMask | A Layer mask that is used to selectively ignore colliders when casting a ray. |
| queryTriggerInteraction | The amount of hits stored into the results buffer. |
int @return True если луч пересекся хотя-бы с одним коллайдером,в ином случае - false.
Casts a ray, from point origin, in direction direction, of length maxDistance, against all colliders in the Scene.
This method generates no garbage.
