Ok so it turns out that that's an error that you also get when you forget to .build() your deserialized objects...

I can't remember why I was doing this with my library, I think I read somewhere that building the objects in AE would impede some other process, maybe it was the animations.... so I was only calling .calcBoundingBox() and .calcNormals()...and this was working fine in another AE project..... but yeah, seems like I need to remember to always build all objects!...

Thanks for your prompt reply!

Awesome job, man. May I suggest integration with Raft's bones for Ogre files? That would be great.

And a couple more suggestions: you should be able to bitwise or Check Others with Check Self. And Set Object Properties could have a button for setCulling (I was testing jBrush with a caped model, which is why I came upon this one). Thanks for the great job.

Thank you very much. I should be able to fix the collision setting and add an option for Culling in the next release soon.

Being able to preview skeletal animations with Raft's Bones would be a nifty feature, maybe be able to mix animations by assigning different sequences to different groups of bones.... but it'd be quite a bit of work, for which I don't really have the time at present, but maybe later on!

Thanks again for the feedback.

EDIT:
Have just uploaded v0.27with an option to set the object's culling and to bitwise Check Others and Check Self.

Thanks for the feature! Really appreciate it 

Have set maxPolys to 250000, have seen that in a few examples in the forum, that seems plenty....

And yeah, i realised there was a small bug in the mouse/camera mapping...have added a fix for it though the camera still lags a bit in changing direction if you quickly change the mouse movement direction while dragging it.... have sent you a PM with the incriminated code snippet, maybe you have a better solution for that....

Have re-uploaded the package.

Will update this thread when the new features are ready!

UPDATED ON 12/02/2012 - Version 0.3

Hello all,

This is a JPCT software I have created as part of a student project. It started as an exercise on the use of JPCT and it developed into this fairly complex toolkit that I used to create most part of an Android game currently available on the Android Market. I developed it a way that it could hopefully be of use to other JPCT users in their projects. While a number of versions were released, correcting a number of bugs reported, the software may still contain bugs (for which reports are appreciated!).

jBrush is a World and Animation editor. It allows you to import 3DS, OBJ and MD2 models, do the usual scale, rotate and translate operations. It has a 3DSMax-like interface where you can navigate the camera through the environment, rotate it around an object, position it front, side or on top of the scene.

World Editor:
In jBrush you can assign textures, most of the Object3D properties (name, collision, transparency, culling, emissive color, bumpMap, parent/child). You can also set up point lights, ambient light. The tool lets you export the scene as an instruction file which can be imported with two to three lines of code inside your JPCT/AE project with the aid of the library that comes with it. The library creates Object3Ds for all the models in the scene and it lets you fetch any of the them by the name given in the editor so that they can be used for further game actions.

Animation Editor:
jBrush is also a keyframe animation viewer and editor. It allows you to playback MD2 animations and to create your own animations out of 3DS keyframe meshes for a model (e.g. the 3-4 main stances of a walk-cycle) and set name and speed to the sequence created.
When linked to your project the library will take care of all the animation routines so that for any Object3D you can start or stop an animation with just one line of code. You can play animations continuously or play them once, at the same speed set up in the editor.

Serializer Tool:
Finally jBrush works as an interface to JPCT's Serializer facility, so it lets you export any supported model in serialized format (.ser) for more efficient processing on the Android.

An example use of this tool for instance is to create a scene with the environment models, create keyframe animations for an enemy, place the enemies inside the map and export the entire scene. The library will let you import the scene and fetch all models whose name contain a given parameter (e.g. "enemy") and with one line of code you can play their "moving" animations and execute further game code on them.

ADDITIONAL FEATURES FOR Version 0.25:

• Triggers and GUI editors. Create trigger volumes and place them in the map. Use the library functions to have the engine check for collisions between triggers and game objects in order to trigger behaviour (opening of doors, elevators, activation of enemies, starting a cutscene et cetera.)
• Create GUIs and Heads Up Display icons from image files, edit them and position them in the in-game screen. Use the library functions to dynamically turn GUIs on or off, change their position and size in-game.

ADDITIONAL FEATURES FOR Version 0.26:

• Playback MD2 animations in the editor.
• Serialize, reduce and export both MD2 animated models and Animations created in jBrush out of 3DS meshes (higher memory optimization for Android with the latter).

ADDITIONAL FEATURES FOR Version 0.28:

• Set culling and collision properties
• Set objects' parent/child dependencies and preview parented movements in editor
• Get position and orientation of editor camera (useful for recreating a specific view angle in game)
• Wireframe view mode (Useful when scene gets complex and you need to see through objects)

ADDITIONAL FEATURES FOR Version 0.3:

• Adjust visibility of objects
• Several bug fixes
• Methods for loading level file from URL document base (for JPCT applets)
• Optimized loading of serialized objects and animations for AE
• Improved documentation

Place collision volumes (triggers) in the scene and create GUIs and Heads Up Display icons.

Thanks for your exhaustive answers. Always very helpful. I managed to complete most of what I had in mind. I can't really find a way to enable the user to remove an existing sequence as the current Animation.remove() method removes that data but not the actual array entry so that it will keep showing up the Animation info but if accessed or checked it just gives a big crash....

Thats a bit of a let down but the editor is functional nonetheless...

PS

I've sent you a PM!

brilliant. A check for a null values solved it... I really hand't seen that in the DOCs.... Thanks for your prompt help!

The error is (at least i think that this is the problem) that your lastMousePos is only valid as long as you are dragging. Once the dragging is over and you start a new one, they have to be set to the current mouse coordinates...not to some position from the end of the last dragging.

Ok, thanks for that! I'm making progress. So now I am recording the mouse positions whenever the cursor is moving, then when I am dragging I stop recording the cursor and calculate the difference between the latest cursor position and the new drag coordinates:

    public void mouseMoved(MouseEvent e) {
    if(!dragging){
    lastMousePosX = e.getX();
    lastMousePosY = e.getY();
    }
    }
public void mouseDragged(MouseEvent e) {
    dragging = true;

    int newMousePosX = e.getX();
    int newMousePosY = e.getY();
   
    ew.rotateView((lastMousePosX - newMousePosX) /50, (newMousePosY - lastMousePosY) / 50);

    System.out.println("" + (lastMousePosX - newMousePosX) + " , " + (newMousePosY - lastMousePosY));
    dragging = false;
    }

This does basically what I wanted it to. Only problem is that if I am dragging left and during the drag I change direction to right the camera keeps going left, which is slightly annoying... any idea what that may be?.....

but for single direction drags this works fine, so thanks for your help!

mmm, it does jerk back in my case.... maybe it's because in your example you are using lwjgl.input to calculate the delta x and y... i wrote my own listener so as to avoid attaching other libraries, this is what it does:
public void mouseDragged(MouseEvent e) {
    if(lastMousePosX == 0 || lastMousePosY == 0){
    lastMousePosX = e.getX();
    lastMousePosY = e.getY();
    }
   
   
    int newMousePosX = e.getX();
    int newMousePosY = e.getY();
   
    ew.rotateView(newMousePosX - lastMousePosX, newMousePosY - lastMousePosY);
   
    lastMousePosX = newMousePosX;
    lastMousePosY = newMousePosY;

    }

Maybe it's the way that the dx/dy are returned that cause the camera to always reset to point at the origin? Does lwjgl do this differently?

Thanks for your help!
