# Class Sprite

java.lang.Object
com.codename1.gaming.Sprite

All Implemented Interfaces:
  `PhysicsLinkable`

Direct Known Subclasses:
  `AnimatedSprite`

public class Sprite extends Object implements PhysicsLinkable

A drawable image with position, rotation, scale, tint and a normalized anchor.

A sprite is a lightweight data holder: it describes what and where, while a `SpriteRenderer` turns it into a GPU textured quad each frame (using the `com.codename1.gpu` package -- an orthographic camera in pixel space, a `com.codename1.gpu.Material.Type#SPRITE` material and alpha blending). Because a sprite never touches the GPU directly you can create one with just an `com.codename1.ui.Image` -- the renderer uploads and caches the matching `com.codename1.gpu.Texture` on demand.

`#getX()`/`#getY()` is the location of the anchor point (the image center by default); rotation and scale pivot around that anchor. `Sprite` implements `com.codename1.gaming.physics.PhysicsLinkable` so a physics body can drive it -- see `com.codename1.gaming.physics.PhysicsWorld`.

  ### Methods inherited from class Object

  `clone, equals, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait`

- ## Constructor Details

  - ### Sprite

    public Sprite()
    Creates an empty sprite with no image.

  - ### Sprite

    public Sprite(Image image)
    Creates a sprite drawing the given image, anchored at its center.

- ## Method Details

  - ### onUpdate

    protected void onUpdate(double deltaSeconds)
    Per frame update hook. The default implementation does nothing; subclasses such as `AnimatedSprite` override it to advance over time. `Scene#update(double)` invokes this for every sprite it contains.

  - ### getRenderWidth

    public float getRenderWidth()
    The width in pixels the sprite renders at before scaling -- an explicit size if one was set, otherwise the image width.

  - ### getRenderHeight

    public float getRenderHeight()
    The height in pixels the sprite renders at before scaling.

  - ### getBounds

    public Rectangle getBounds()
    Returns the axis aligned bounding box of the (scaled) sprite, ignoring rotation. Useful for broad phase collision checks.

  - ### intersects

    public boolean intersects(Sprite other)
    Returns true if this sprite's bounding box intersects the other's.

  - ### setPhysicsPosition

    public void setPhysicsPosition(float xPx, float yPx)
    Description copied from interface: `PhysicsLinkable`
    Sets the object's position from the body center, in pixels.
    Specified by:
      `setPhysicsPosition` in interface `PhysicsLinkable`

  - ### setPhysicsRotation

    public void setPhysicsRotation(float radians)
    Description copied from interface: `PhysicsLinkable`
    Sets the object's rotation from the body, in radians (clockwise positive in screen space).
    Specified by:
      `setPhysicsRotation` in interface `PhysicsLinkable`
