Hi guys! I have a little big question about TextureAtlas and the soft TexturePacker.

First of all, I created 4 simple images, all same size. Put them into the TexturePacker and configured it to work with libGDX. The first thing is that one of the 4 images show up rotated into the atlas (to gain space?) Anyway, I keep going with this tutorial: http://bitiotic.com/blog/2012/05/10/tutorial-for-texturepacker-and-libgdx/

So...I publish de atlas, get the 2 files and then inside libGdx:

1  
2  
3  
4  
5  
6  
atlas= new TextureAtlas(Gdx.files.internal("assets/atlas_test/pack1.txt")); 

fig1= atlas.findRegion("fig1");
fig2= atlas.findRegion("fig2");
fig3= atlas.findRegion("fig3");
fig4= atlas.findRegion("fig4");


And the render method:

1  
2  
3  
4  
5  
6  
7  
8  
batch.begin();
     
batch.draw(fig1, 0, 200);
batch.draw(fig2, 0, 400);
batch.draw(fig3, 200, 400);
batch.draw(fig4, 200, 200);
     
batch.end();


The output:

Not so cool, uh? i can understand that the packer rotates images to gain space but...when I load them I wanted without rotation!

This is the .txt generated by the TexturePacker:

pack2.png
format: RGBA8888
filter: Linear,Linear
repeat: none
fig1
  rotate: true
  xy: 2, 145
  size: 151, 141
  orig: 151, 141
  offset: 0, 0
  index: -1
fig2
  rotate: false
  xy: 308, 2
  size: 151, 141
  orig: 151, 141
  offset: 0, 0
  index: -1
fig3
  rotate: false
  xy: 155, 2
  size: 151, 141
  orig: 151, 141
  offset: 0, 0
  index: -1
fig4
  rotate: false
  xy: 2, 2
  size: 151, 141
  orig: 151, 141
  offset: 0, 0
  index: -1


Seems to be fine but the "findRegion" method just check the name and returns the region. It doesn't care about rotation. I don't know...Im doing something wrong?

Nevermind. I found the option "allow rotation" in the TexturePacker. If it's unchecked the packer just put the images without any rotation.
