User controlled joints



    I had posted this is a follow up question in my own thread but didn't get any replies. I am attempting to let the user rotate each body part of a character imported from Milkshape. Anyone who has done something about this please let me know. I tried adding a controller to JointMesh in the file but had no success. HamsterOfDeath's code is for reading animations per joint. Whereas what I want is that the user of my tool is able to rotate and translate each body part the way it is done in MAX or any modelling software. In a way, I am trying to build the animations programatically.

This is my modification of the readGroups() method in order to set a controller for the joints. But this doesn't seem to work at all.

private void readGroups() throws IOException {
        int nNumGroups=inFile.readUnsignedShort();
        materialIndexes=new int[nNumGroups];
        for (int i=0;i<nNumGroups;i++){
            inFile.readByte();      // Ignore flags
            inFile.readFully(tempChar,0,32);    // Name
            int numTriLocal=inFile.readUnsignedShort();
            Vector3f[] meshVerts=new Vector3f[numTriLocal*3],meshNormals=new Vector3f[numTriLocal*3];
            Vector3f[] origVerts=new Vector3f[numTriLocal*3],origNormals=new Vector3f[numTriLocal*3];
            Vector2f[] meshTexCoords=new Vector2f[numTriLocal*3];
            int[] meshIndex=new int[numTriLocal*3];
            int[] jointIndex=new int[numTriLocal*3];
            JointMesh theMesh=new JointMesh(cutAtNull(tempChar));

            for (int j=0;j<numTriLocal;j++){
                int triIndex=inFile.readUnsignedShort();
                for (int k=0;k<3;k++){
                    meshVerts       [j*3+k]=myVerts[myTris[triIndex].vertIndicies[k]].vertex;
                    meshNormals     [j*3+k]=myTris[triIndex].vertNormals[k];
                    meshTexCoords   [j*3+k]=myTris[triIndex].vertTexCoords[k];
                    meshIndex       [j*3+k]=j*3+k;
                    origVerts       [j*3+k]=meshVerts[j*3+k];
                    origNormals     [j*3+k]=meshNormals[j*3+k];
                    jointIndex      [j*3+k]=myVerts[myTris[triIndex].vertIndicies[k]].boneID;
                    BufferUtils.createFloatBuffer(meshNormals), null,

            InputHandler input = new InputHandler();         //This is New
            KeyBindingManager keyboard = KeyBindingManager.getKeyBindingManager();   //This is New
            NodeHandler nc1;       //This is New
            Node selectedNode;    //This is New   
            nc1 = new NodeHandler(theMesh, 5, 1 );  //         This is New
            input.addToAttachedHandlers( nc1 );  //         This is New
            keyboard.set("node1", KeyInput.KEY_SPACE);       //         This is New
              InputAction buttonAction = new InputAction() {      //         This is New
            public void performAction( InputActionEvent evt ) {    //         This is New
                System.out.println( "button action performed" );     //         This is New
            }                                                                       //         This is New
            input.addAction( buttonAction  , "node1", false );      //         This is New
            finalNode.updateRenderState();                               //         This is New

Please let me know how can I make the controlling of joints through mouse or even keyboard possible.

Thank you
