Windows EXE does not build after switching to 3.1 alpha

Troubleshooting General Help
1

Hello Monkeys,

I just transfered my large project from 3.0 to 3.1 and got a few surprizes.

I use the 3.1 librairies.

When I used to build the exe it would create a very large exe and the standard librairies.

Now, it creates a tiny EXE with the standard librairies AND all my assets and classes visible.

After doing the jar, MACOSX and WIN EXE, I think it tries to create the standard (large) EXE but I get the following error:

Windows EXE Creation

using the classloader AntClassLoader[]

Soā€¦ how get I get my large EXE back ??

Here is the full output:

Open the project in 3.0, disable desktop publishing, open in 3.1 re-enable the (new) desktop publishing. Generally Iā€™d suggest making a completely new project and simply copying the src and assets folder over.

The fact that the new desktop publishing has a separate (small) exe is normal though.

3

Ok, I will try creating a new project

FYI

Had to remove the following from all my materials files that use lighting:

vtangent
usealfa
minnert
lowquality
highquality

4

Opening a j3m file and making a change so that it saves should get rid of the invalid parameters.

Ok, almost back on trackā€¦

I get collision exeptions when I collide bounding box.

I there a new way to do this?

CODE:

Spatial obj = s.clone();

    CollisionResults results = new CollisionResults();    
    obj.setLocalScale(0.99f);
    BoundingVolume b = obj.getWorldBound();
    
    planet.nodeCol.collideWith(b, results); 
    if(results.size() > 0) 
        return false;
    return true;

Looking at the code, it looks like BB to BB collisions were never supportedā€¦ not even in 3.0

7

Sure about this?

8

I know :rage:

9

Itā€™s non-trivial because JME collisions are ā€˜single pointā€™ collisions and there is no single point collision between to BBs. A full up collision system can deal with edge->edge, vertex->edge, and so onā€¦ this is simpler than that.

It may be time to rethink what you are doing as itā€™s somewhat rare to need BB to BB collision outside of the physics engine.

10

In fact, now Iā€™m checking collisions with 2 or 3 alternative ways.

11

Thatā€™s what worked for me. Open the j3m, toggle a checkbox twice so the editor thinks itā€™s ā€˜dirtyā€™ and saves the j3m.

12

Wonderful! :smiley:

13

The code for creating j3m files is a bit ugly but pretty smart :wink:

14

Nehon: no, that did not work, I had to redo all the materials

15

I can assure you that BB to BB worked in 3.0.

Anyhoo, what I need is to collide my ā€˜ā€˜ghost buildingsā€™ā€™ to my main collision node to see if anything is in the way. I have a loop where you can build one or multiple objects with a ghost of the building(s) in a red or green transparent material depending on the collision result. I also used this to check collisons on my player cylinders.

Have I been doing it wrong all this time? What should I use???

16

That would be quite the trick since the code has not changed there in a long time:
https://code.google.com/p/jmonkeyengine/source/browse/trunk/engine/src/core/com/jme3/bounding/BoundingBox.java#761

^^ 3.0 code that throws an exception for anything but ray and triangle.

17

You only care about boolean intersection so do intersect tests. Depending on how many objects you have, you might want to organize them into a fixed cell size grid for easy reduction of tests.

Hey pspeed sorry I made a mistake. I was using a sphere for the collision.

I found this in my code :wink: :

    bv = null;
    if(bv == null){
        Mesh mesh1 = new Sphere(10, 10, radius);
        Geometry geom1 = new Geometry("TestCol", mesh1);
        geom1.setLocalTranslation(p);
        bv = geom1.getWorldBound();                   
    }  
    
    CollisionResults results = new CollisionResults();        
    planet.nodeCol.collideWith(bv, results);

I forgot I put bv = null; at the top so I actually thought I had a bounding volume parameter lol

nodeCol is of type Node. Itā€™s where most of my collidables are.

This works fine (for spheres) in 3.0 but not 3.1. I used it to know when my character runs into an object and make him freeze when he hits anything that is in the physics realm.

So like, how can I make my character not go through walls and stuff?

I also donā€™t get how I can make him strafe along the walls instead of blocking when he hits one. In games, the player usually just moves slower when he is running against the wall, and only stops if you are 100% perpendicular right?

My idea for this would be to get a ray collision after the hit, get the normal vector and use that along with the players dir vector to figure out wich way he should move. Rigidbody physics makes that a bit hard??

19

If you are using physics then it should already be doing it for you.

If you are not using physics then you push the character back along the collision normal by some factor of the penetration.

Edit: but using JME Spatial collidesWith() this only works for sphere to BBā€¦ meaning all of your walls would have to be axis-aligned or it would look stupid.

20

Ok, great thanks for that.

Edit: I tested the ā€œTestTriangleCollisionā€ from JMETest with a sphere instead of the box and it worksā€¦

I compared that to what I do and the only difference is that instead of colliding with golem I collide with a node that has a bunch of stuff in in.

Is there anything that my node could have in it that would spark this exception below ? All I did was transfer my code and assets from 3.0ā€¦

It crashes right when I do this:

planet.nodeCol.collideWith(bv, results);

bv i got from: geomOfSphere.getWorldBound()
nodeCol is a node with a few other nodes and spatials in it.

Please help this is driving me mad :frowning:

Edit: I have a leed!

I replace bv with null in 3.0 and 3.1

please look at the difference in the stack trace:

In 3.0
