SpriteBatch -> 2x performance improvement anyone?

[bermuda2810]

Hi, Nicolas Gramlich
First time, im sorry about my E
I'm using SpriteBatch. And i have seen example of SpriteBatch in http://code.google.com/p/andengineexamples/source/browse/src/org/anddev/andengine/examples/SpriteBatchExample.java
but when I test it ,occuring bug :

I'm curious how that would have even compiled o_O...
Can anyone confirm this

Is there someway to change the capacity of the SpriteBatch/SpriteGroup after it is created?
Also, can you attach another SpriteBatch to a SpriteBatch?

I got the same issue. 'Fixed' it by removing the @SuppressWarnings annotation on the drawVertices method in the SpriteBatch class.
Changed from: private void drawVertices(final GL10 pGL, @SuppressWarnings("unused") final Camera pCamera)
to: private void drawVertices(final GL10 pGL, final Camera pCamera)

recompiled it, and it worked. I have no idea why that caused the issue though....

Same problem here. Fixed it with the solution from Anilin.

Hello, I decided to implement SpriteBatch feature to improve performance of my game.

Im adding my "coins" sprites to the sprite batch with this way:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

1. coinsBatch.draw(new Coin(x, y, width, height, groundTilesNormalTextureRegion));

Parsed in 0.029 seconds, using GeSHi 1.0.8.4

It works, they are drawn on the scene, but they act like normal sprite (Coin class is extension of the sprite, with collision check, and entity modifier)

Using java Syntax Highlighting

1.         private class Coin extends Sprite
2.         {              
3.                 private boolean received = false;
4.                
5.                 public Coin(float pX, float pY, float pWidth, float pHeight, TextureRegion pTextureRegion)
6.                 {
7.                         super(pX, pY, pWidth, pHeight, pTextureRegion);
8.                         registerEntityModifier(new LoopEntityModifier(new ScaleModifier(1, 1f, 1.3f)));
9.                 }      
10.                
11.                 @Override
12.                 protected void onManagedUpdate(final float pSecondsElapsed)
13.                 {              
14.                         runOnUpdateThread(new Runnable()
15.                         {
16.                                 @Override
17.                                 public void run()

20.                                         {
21.                                                 scene.detachChild(Coin.this);
22.                                                 GameManager.playSound(coinPickSound);
23.                                                 received = true;
24.                                                 addToScore(10);
25.                                         }
26.                                 }
27.                         });
28.                         super.onManagedUpdate(pSecondsElapsed);
29.                 }
30.         }

Parsed in 0.034 seconds, using GeSHi 1.0.8.4

But while using sprite batch, nothing happens (no reaction for collisions, and modifier doesnt work aswell)

Help please!

Do someone could tell me if this SpriteBatch methodology could be used to improve classical AnimatedSprite animations FPS?
As of today, I create a TiledTextureRegion, I assigned it to an AnimatedSprite and when I need it I start it using myanimatedsprite.animate(100).
May I improve my approach using SpriteBatch or this is not my case?

You cannot tell that for sure upfront, but it is worth a try (SpriteGroup btw instead of SpriteBatch, because SpriteBatch won't update each frame). The more sprites you have, the better.

Nicolas, could you give me the answer on this question http://www.andengine.org/forums/development/spritegroup-and-andenginetexturepackerextension-t5842.html?

[bmfs]

Should we also use SpriteBatch if we have multiple sprites which are static but have different Textures?
