    Walter may testify that I was very reluctant to include the ShaderProgram class in libGDX because shader programs are mainly used in 3D, are complex to write and to use and I'm not an expert in this matter. On the other hand, most of the Wow! effects nowadays are made with these shader programs and everybody wants to include them in his/her application, so I don't want to prevent you from being a fashionista. ;) But don't count on me to explain anything about this. I prefer to explain how to do traditional effects that use a lot less CPU and GPU. It doesn't seem to me that the games were dull and ugly before OpenGL 2!

    There's a tutorial (written by someone else) for the ShaderProgram demo. The link is given at the beginning of the code.

    Hahahahaha no worries about it, frankly speaking in regards my age i'm not ready to become a fashionista, or a fashion victim ;)
    But as you told right in your tuts before, we need to adapt our way to program and think about.
    Me also, i was a programer on basis languages like assembler many time ago.
    But that's the past and now people want more and more, and unfortunatly we aren't born named Iwatani :)

    No worries and thank you for the indication about the link.
    But link don't work

    this is incredible. thank you very much. I'm trying to make a game, very simple, based on a couple of examples. but? how I can make the effect of example Particles fill the screen or move around it? and how I can see the file .p?
    Thanks and very good work. this library in itself is an infinite source of possibilities

    about move efect :
    Code:
    Effect.SetPosition(Rnd(0,lGdx.Graphics.Width), Rnd(0,lGdx.Graphics.Height ))
    ,i ask and i answer myself.
    only then .p and fill screen with effect.
    :)

    The file .p is produced by the Particle editor and the size of particles is defined with this editor. Please read the chapter devoted to particles in the tutorial.

    And please how i can open .pack? i can´t see in google any program.
    Thanks

    The .pack files are the index of texture atlases. They are created by the texture packer tool. They can have any extension. It doesn't matter.

    In the example Scn2D Drag'n'Drop,
    Code:
    Atlas.InitializeWithFile("atlas/dragdrop.pack")
    then
    Code:
    DogHouse.Initialize3(Atlas.FindRegion("doghouse"), "")
        Stage.AddActor(DogHouse)
    please can you explain me how can localice it if in the .png are "house","family","dog","cat" and "doghouse". In the code not appears "dragdrop.png",then this is in "dragdrop.pack"?

    From the chapter "Texture Atlas" of the tutorial, about the texture packer:
    "This tool stores the images in the atlas with their file name without extension."

    Ok,thank you very much,now i understand how this works. I download libgdx-texturepacker-gui.
    I will try to make an atlas.
    But i think i never end this library,every step i do forward then i go two back .
    Thank you again.

    Please this is copy of the drag and drop example,y only create "chori.pack",but if one item go to the wrong target,dissapears ,don´t return to the original position.
    Can you help me?
    this is the code and the files zip.
    Thank you,and sorry if i´m heavy :-(

    In SrcDragStop, I see no code replacing the actor to its original position if the drop location is invalid, so there's no surprise here.
    In my Drag n Drop example I use a drag actor (e.g. CatDrag for the Cat actor) so I don't need to replace anything (the source actor does not move, it is just made visible/invisible).

    Without the code of other activities, I cannot say anything about your error. It is not related to the code that you sent.
