java - Add animation into Sprite.draw(SpriteBatch) method -

if possible add animation sprite.draw(spritebatch) method. according proper scaling in multidimensial screens use viewports , displaying textures this:

player= new sprite(new texture("player.jpg"));         player.setsize(player_size,player_size);         player.setposition(0,0);    @override     public void render(spritebatch sb) {         sb.setprojectionmatrix(camera.combined);         sb.begin();         player.draw(sb);         sb.end();     } 

i want animate movement of texture whenever move. after searching found 1 way required spritebatch.draw(animation.getkeyframe(elapsed_time),position.x,position.y), there way this?

the simple answer animation class provided libgdx https://libgdx.badlogicgames.com/nightlies/docs/api/com/badlogic/gdx/graphics/g2d/animation.html

here goes how works:

• create sprite map animation frames using favorite graphic tool.

• knowing dimensions split sprite map, i.e.:

  texture spritemap = newtexture(gdx.files.internal("images/sprite-map.png")); textureregion[][] spriteposition = textureregion.split(spritemap, frame_width, frame_height); 

• next, create animation class animation, example bomb exploding, need pick right coordinates sprite map, sprite map 2 dimensional matrix. can example:

  textureregion[] bombsprites = new textureregion[4]; bombsprites[0] = spriteposition[5][6]; bombsprites[1] = spriteposition[5][7]; bombsprites[2] = spriteposition[5][8]; bombsprites[3] = spriteposition[5][9]; animation bombanimation = new animation(0.1f, bombsprites); 

• having animation prepared, need have class created extends actor class. i.e.:

  public class bomb extends actor {   ... (some fields , methods)  @override  public void draw(batch batch, float parentalpha) {   ...  } 

• you need override act method:

  @override public void act(float delta) {    this.statetime += delta; } 

• after use batch.draw method in overridden draw() method invoke

  batch.draw(animation.getkeyframe(this.statetime, true) 

that's what's requirement simple animation
