« on: January 25, 2016, 11:16:06 am »
i try to load a texture from .zip file.
model is ok,but i cannot load texture;

Code: [Select]
try {
                String path = bundle.getString("path");
                modelStream = ZIP.UpZip(path, "model.3ds");
                textureStream = ZIP.UpZip(path, "texture.png");
                Texture texture = null;
                if (textureStream != null && modelStream != null) {
                    try {
                        texture = new Texture(BitmapHelper.rescale(BitmapHelper.loadImage(textureStream),64,64));
                        fb.blit(texture, 0, 0, 0, 0, 128, 128, 128, 128, 10, true, null);

                        TextureManager.getInstance().replaceTexture("texture", texture);
                    } catch (Exception e) {
                        e.printStackTrace();
                    } finally {
                        model = Object3D.mergeAll(Loader.load3DS(modelStream, 1));
                        if (texture != null)
                            model.setTexture("texture");

                        model.clearRotation();
                        model.rotateX(-(float) Math.PI / 2);

                        model.strip();
                        model.build();

                        world.addObject(model);

                        cam.lookAt(model.getTransformedCenter());
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
