Class Scene

java.lang.Object
com.codename1.gaming.Scene
public class Scene extends Object

A z-ordered collection of sprites with an optional camera offset.

A Scene is the model a SpriteRenderer draws: it holds the sprites, keeps them sorted by Sprite#getZOrder() (higher draws on top, re-sorted only when the contents change) and applies a camera offset that scrolls the whole scene. #update(double) advances every sprite (driving AnimatedSprite playback).

  • Constructor Details

    • Scene

      public Scene()

  • Method Details

    • add

      public void add(Sprite s)
      Adds a sprite to the scene.

    • remove

      public void remove(Sprite s)
      Removes a sprite from the scene.

    • clear

      public void clear()
      Removes all sprites.

    • size

      public int size()

    • get

      public Sprite get(int index)

    • update

      public void update(double deltaSeconds)
      Advances every sprite in the scene by calling Sprite#onUpdate(double). Iterating by index tolerates a sprite removing itself during update.

    • markSortDirty

      public void markSortDirty()
      Forces a re-sort on the next frame. Call this after changing a sprite's z-order so the new ordering takes effect.

    • getCameraX

      public int getCameraX()

    • getCameraY

      public int getCameraY()

    • setCamera

      public void setCamera(int x, int y)
      Sets the camera offset subtracted from sprite positions while rendering.
