    • raycast

      public boolean raycast(com.badlogic.gdx.math.Vector2 from, com.badlogic.gdx.math.Vector2 to, RaycastHit hit)
      Cast a ray in a straight line from one point to another, checking for a collision against any colliders.
      Parameters:
      from - The starting point of the ray.
      to - The end point of the ray.
      hit - The raycast result will be stored in this class
      Returns:
      true if a collider was hit, false otherwise.

    • raycast

      public boolean raycast(com.badlogic.gdx.math.Vector2 from, com.badlogic.gdx.math.Vector2 to, short layerMask, RaycastHit hit)
      Cast a ray in a straight line from one point to another, checking for a collision against colliders in the specified layers.
      Parameters:
      from - The starting point of the ray.
      to - The end point of the ray.
      hit - The hit of the closest collider will be stored in this.
      layerMask - The physics layer mask which specifies layers that can be hit. Other layers will be ignored.
      Returns:
      true if a collider was hit, false otherwise.

    • raycastAll

      public RaycastHit[] raycastAll(com.badlogic.gdx.math.Vector2 from, com.badlogic.gdx.math.Vector2 to)

      Parameters:
      from - The starting point of the ray.
      to - The end point of the ray.
      Returns:
      All hits made by the ray, unordered. Empty if no hits were made.
