How to run a new class in SH3D source

[Mitsaki]

Hello again,

I have started programming and I created a new package in the existing SH3D source code. In this new package I have created a class that is used to create a new Home, with walls and furniture. When I run this class, the interface of SH3D is opened but nothing is created. (I run this class using the instructions of README.txt and having as a main class com.eteks.sweethome3d.SweetHome3D).
Could you tell me what I am doing wrong??

PS. My code seems to have no mistakes.

Mitsaki [:(]

Sorry, but with no source code, it's just impossible to help you!!! [:(]

Where should I copy paste this code...
It seems not to work at all.

Ok, I think I understood what you want to do now.
If you want to display a home built by program from a derived version of Sweet Home 3D, you should:
- create a subclass of com.eteks.sweethome3d.SweetHome3D application class,
- add a main method that will instantiate and init the application from the arguments
- override the createHome method to return a com.eteks.sweethome3d.model.Home instance initialized the way you want.
Here's a base example:

Code: Select all

import com.eteks.sweethome3d.SweetHome3D;
import com.eteks.sweethome3d.model.Home;

public class Test extends SweetHome3D {
  public static void main(String [] args) {
    new Test().init(args);
  }
  
  @Override
  public Home createHome() {
    Home home = super.createHome();
    // Modify home as you wish here
    return home;
  }
}

Hope this will help you to start. [:)]

[Mitsaki]

Is there any change that I should write this into my code?

SweetHome3D Home3D = new SweetHome3D();

Home3D.addHome(Parallelogram);

Although, it still doesn't work...

[Mitsaki]

Sorry, I didn't see your reply:)))
I hope it works!!!

[Mitsaki]

The thing is that I was expecting to have something created, a wall, a room...
but nothing is displayed.

Here is the code, after the changes.

You shouldn't call blender.createHome(); directly and your createHome method doesn't return the home to which you added all your walls!
Instantiate only once the Home class with super.createHome(); call and add the walls to this instance.

[Mitsaki]

Well, I corrected my mistakes and I call the method with what you suggested:

new Blender().init(args);

but I don't see any results in the interface
