This is driving me a bit mad 
I’m trying to navigate around as the camera the ASE file I have loaded up - which is a basic room. I have added a CollisionNode to the rightwall, so when I translate hopefully I’ll hit it. I’ve also added a CollisionNode to the TransformGroup holding the view. Nothing changes ???
I’ve tried quite a lot of things, but here’s the basic code without all the fiddly hacks.
public class ColTest04 implements KeyListener
{
TransformGroup objTranslate = null;
Transform3D translate = null;
TransformGroup objRotate = null;
Transform3D rotate = null;
TransformGroup room = null; //entire room
TransformGroup rightwall = null;
View view = null;
Canvas3D canvas = null;
Vector3f position = new Vector3f(0.0f, 15.0f, 0.0f);
Vector3f angle = new Vector3f(0.0f, -90.0f, 0.0f);
CollisionSystem cs = new CollisionSystem(-1);
public static void main(String[] args)
{
try
{
ColTest04 test = new ColTest04();
}
catch(Exception e) {}
}
public ColTest04() throws Exception
{
TextureLoader.tf.registerPath("./");
VirtualUniverse universe = new VirtualUniverse();
view = new View();
universe.addView(view);
Locale locale = new Locale(5.0f, 0.0f, 10.0f);
universe.addLocale(locale);
BranchGroup scene = new BranchGroup();
locale.addBranchGraph(scene);
//load ASE file
AseFile af = new AseFile();
BufferedReader br = null;
try
{
br = new BufferedReader(new FileReader("2ndgo.ASE"));
}
catch(IOException e)
{
URL url = getClass().getClassLoader().getResource("2ndgo.ASE");
br = new BufferedReader(new InputStreamReader(url.openStream()));
}
AseReader r = new AseReader(br, af);
af.parse(r);
HashMap namedNodes = new HashMap();
room = af.getTransformGroupTree(namedNodes);
scene.addChild(room);
Collection c = namedNodes.keySet();
for(Iterator i = c.iterator(); i.hasNext(); System.out.println(i.next()));
//add collision to rightwall
rightwall.setName("rightwall");
ColliderGeometry cgRightWall = new ColliderGeometry();
cgRightWall.setModel(rightwall);
BiTreeCollider bic = new BiTreeCollider();
bic.build(cgRightWall);
ColliderNode rightwallNode = new ColliderNode(rightwall, ColliderNode.CT_GEOMETRY,
ColliderNode.CT_GEOMETRY, false, bic);
cs.addCollider(rightwallNode);
//create tranform node to hold view & let view along this path translate
translate = new Transform3D();
objTranslate = new TransformGroup(translate);
translate.setTranslation(position);
objTranslate.setTransform(translate);
scene.addChild(objTranslate);
// let view along this path rotate
rotate = new Transform3D();
rotate.rotXYZ(0.0f, 0.0f, 0.0f);
objRotate = new TransformGroup(rotate);
objRotate.setTransform(rotate);
//make it a child of TransformGroup/objTranslate
objTranslate.addChild(objRotate);
//add collision to transform node which holds view
objTranslate.setName("view");
ColliderGeometry cv = new ColliderGeometry();
cv.setModel(objTranslate);
BiTreeCollider bic2 = new BiTreeCollider();
bic2.build(cv);
ColliderNode viewNode = new ColliderNode(objTranslate,
ColliderNode.CT_ELLIPSOID, ColliderNode.CT_GEOMETRY, true, bic2, new Coord3f(0,0,0));
Force gravity = new ForceGravity();
viewNode.addForce(gravity);
cs.addCollider(viewNode);
// create a canvas for our graphics
RenderPeer rp = new RenderPeerImpl();
CanvasPeer cp = rp.makeCanvas(null, 640, 480, 16, false);
canvas = new Canvas3D();
canvas.set3DPeer(cp);
cp.getComponent().addKeyListener(this);
// modify our view
view.addCanvas3D(canvas);
start(view);
}
private void moveCamera(Vector3f position, Vector3f angle)
{
translate.set(position);
rotate.rotY((float) Math.toRadians(angle.y));
translate.mul(rotate);
rotate.rotX((float) Math.toRadians(angle.x));
translate.mul(rotate);
rotate.rotZ((float) Math.toRadians(angle.z));
translate.mul(rotate);
view.setTransform(translate);
}
public void start(View view)
{
while (true)
{
moveCamera(position, angle);
view.renderOnce();
cs.newFrame(10);
}
}
public void keyPressed(KeyEvent e)
{
if(e.getKeyCode() == KeyEvent.VK_LEFT)
{
angle.y = angle.y + 5.0f;
}
//etc........................
}
public void keyTyped(KeyEvent e) {}
public void keyReleased(KeyEvent e) {}
}
I think the solution is something to do with view & the registration of the CollisionNode for it. But I could be wrong.
Thanks.
