I am using android SDK, Eclipse and AndEngine I have created hanoi tower game which works perfectly with 3 rings. When I added one more ring the program malfunctions. How can I fix that? Is that caused from the dimension of my 4th ring or is something in the code to be set? Here is my code with the 4 rings, which crashes at collisions between 2,4 rings or 1,3 rings and so on.
@Override

main_font.load();
// 1 - Set up bitmap textures
backgroundTexture = new BitmapTexture(this.getTextureManager(), new IInputStreamOpener() {
@Override
public InputStream open() throws IOException {
return getAssets().open("gfx/background.png");
}
});
ITexture towerTexture = new BitmapTexture(this.getTextureManager(), new IInputStreamOpener() {
@Override
public InputStream open() throws IOException {
return getAssets().open("gfx/tower.png");
}
});
ITexture ring1 = new BitmapTexture(this.getTextureManager(), new IInputStreamOpener() {
@Override
public InputStream open() throws IOException {

}
