Sky

[Melssj5]

How to add a sky instead of that black enviroment that jpct has by default?

[Mr.Marbles]

I've used the technique described in the following post and it works well. If you just want to use a solid color for the background then you can replace the buffer.clear() with buffer.clear(Color).

use the technic called 'skybox'.

Some free sky textures.

    float size=4000;
    String[] name={"top","front","left","right","back"};
    for (int i=0;i<name.length;i++)
    {
     InputStream in=new FileInputStream(name+".jpg");
     BufferedImage b=null;
     try
     {
      b=ImageIO.read(in);     
     } catch (Exception e) {}
     Texture pic=new Texture(b,false);
     pic.enableGLClamping();
     TextureManager.getInstance().addTexture(name,pic);
    }
    Object3D[] o=new Object3D[name.length];
    //top
    Object3D obj=Primitives.getPlane(1,size*2);
    obj.rotateZ((float)Math.PI/2);
    obj.rotateX((float)Math.PI/2);
    obj.translate(0,size,0);
    o[0]=obj;
     //front
    obj=Primitives.getPlane(1,size*2);
    obj.translate(0,0,size);
    obj.rotateZ((float)Math.PI);
    o[1]=obj;
    //left
    obj=Primitives.getPlane(1,size*2);
    obj.translate(size,0,0);
    obj.rotateZ((float)Math.PI);
    obj.rotateY((float)Math.PI/2);
    o[2]=obj;
    //right
    obj=Primitives.getPlane(1,size*2);
    obj.translate(-size,0,0);
    obj.rotateZ((float)Math.PI);
    obj.rotateY((float)-Math.PI/2);
    o[3]=obj;    
    //back
    obj=Primitives.getPlane(1,size*2);
    obj.translate(0,0,-size);
    obj.rotateZ((float)Math.PI);
    obj.rotateY((float)Math.PI);
    o[4]=obj;    
   
    for (int i=0;i<name.length;i++)
    {
      o.setTexture(name);
      o.setLighting(Object3D.LIGHTING_NO_LIGHTS);
      o.build();
      world.addObject(o);
    }

You can also use a more simple method like raft did here :

Well, i set my map inside an empty sphere, and I gave the sphere a texture of a sky
