为什么libgdx新版本使用图块单元来设置相机的位置？

Question

I'm trying to put the new version of libgdx 0.9.8 -> 1.0.1.

I use a tilemap and an OrthographicCamera with an OrthogonalTiledMapRenderer .

This is my camera implementation :

map = tileMapHelper.getMap();
renderer = new OrthogonalTiledMapRenderer(map, 1/128f);
camera = new OrthographicCamera(width, height);
camera.setToOrtho(false, 5, (float)(height/128f));

So when I try to move up the camera (just 2 pixels), I do this :

camera.position.set(camera.position.x, camera.position.y + 2, 0);

Unfortunately, this operation moves up the camera 2 tiles.

How can I move my camera with only pixels ?

Thanks.

By passing a unitScale of 1/128f to the renderer, and using a camera viewport of 5 x (height/128f) you are telling libgdx you want the camera units to be tiles instead of pixels.

Either don't use tile dimensions for the camera and map renderer, or divide all of your pixel values by 128f to convert them to tile units.
