Methods

Private updateMaterial

  • _updateMaterial(): void

init

  • init(): void

postUpdate

  • postUpdate(deltaTime: number): void

  • 执行一次物理系统的模拟，目前将在每帧自动执行一次。

    Parameters

    • deltaTime: number

      与上一次执行相差的时间，目前为每帧消耗时间

    Returns void

raycast

  • raycast(worldRay: ray, mask?: number, maxDistance?: number, queryTrigger?: boolean): boolean

  • 检测所有的碰撞盒，并记录所有被检测到的结果，通过 PhysicsSystem.instance.raycastResults 访问结果

    Parameters

    • worldRay: ray

      世界空间下的一条射线

    • Default value mask: number = 4294967295

      掩码，默认为 0xffffffff

    • Default value maxDistance: number = 10000000

      最大检测距离，默认为 10000000，目前请勿传入 Infinity 或 Number.MAX_VALUE

    • Default value queryTrigger: boolean = true

      是否检测触发器

    Returns boolean

    boolean 表示是否有检测到碰撞盒

raycastClosest

  • raycastClosest(worldRay: ray, mask?: number, maxDistance?: number, queryTrigger?: boolean): boolean

  • 检测所有的碰撞盒，并记录与射线距离最短的检测结果，通过 PhysicsSystem.instance.raycastClosestResult 访问结果
