java - libgdx sprite dimension meters or pixels? -

-

I'm reading "Learning Libegade Game Development". I tried the following snippet: 

  // The first camera object was created with a 5x5 viewport. Orthographic camera camera = new orthographic camera (5, 5);

I have a texture of 32 pixels with dimensions of 32 pixels. I create a phantom outside of this 

  Sprite spr = new Sprite ( Texture); // I set the size of the SRR as spr.setSize (1,1); According to the book, the above dimensions are meters and there are no pixels 
 
 What I can not understand is how mapping is being done from meters to pixels on the screen? When I had to draw the sprite on the screen, the size is not even half a meter alone. 
 
 In addition, the size of the built-in texture is 32 x 32 pixels when I change the shape, the shape of my preferences also changes 
 
 Then, spr.setPosition (x, y) What will be the dimensions? Will they be meters or pixels?

Texture size in the library such as dimensions and use of pixels - game units

setPosition Game units will move an object. When you move an object X game units, the number of pixels varies depending on the camera's projection matrix between the other settings.

If you think about it, then it will not make sense to grow in pixels. If the camera is more zoomed than a camera, then in each camera scene, two pixels will need two separate vacancies.

EDIT: Sorry, I raised some assumptions in your understanding, partially misunderstood this question, and clearly used misleading terms. The main thing is that the meter conference for the units has been created not , this is the one you apply because the box 2D does not mean the ratio of one pixel to one meter. The word I used is implicit that the interior set regards the status meter, but you should scaling yourself. Often times, what I see in lipidax is 30 pixels = 1 meter.

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
