파라미터

centerCenter of the box.
halfExtentsHalf the size of the box in each dimension.
directionThe direction in which to cast the box.
orientationRotation of the box.
maxDistanceThe max length of the cast.
layerMaskA Layer mask that is used to selectively ignore colliders when casting a capsule.

반환

bool True, if any intersections were found.

설명

Casts the box along a ray and returns detailed information on what was hit.

//Attach this script to a GameObject. Make sure it has a Collider component by clicking the Add Component button. Then click Physics>Box Collider to attach a Box Collider component.
//This script creates a BoxCast in front of the GameObject and outputs a message if another Collider is hit with the Collider’s name.
//It also draws where the ray and BoxCast extends to. Just press the Gizmos button to see it in Play Mode.
//Make sure to have another GameObject with a Collider component for the BoxCast to collide with.
