Hello, I think I've found the problem but I want to be sure before install an other jvm version. When I try to lunch spine (windows 10) it crashes all the time with this error box : Error: Could not create the Java Virtual Machine. Error: A fatal exceptio has occurred. Program will exit.

Here is the log:

Spine Launcher 1.8.15-full
Java 1.8.0_31 Oracle Corporation
Java HotSpot(TM) 64-Bit Server VM
64-bit Java detected.
32-bit Java is required.

Should I install the java vm 32 bit? I think that I have also the 1.7 jvm 32bit installed in my system Can I tell to spine to use that one?

Now you have just one problem: all bodies have the attached TextureRedgion size and rotation. So, you may change body sizes of the concrete bodies. This solution used shapes once created. You don't need to reinitialize the shapes or change the body's parameters.

yeah but also they aren't dynamic bodies and you have N° bodies for each skeleton . it depends which approach you want to use : Box2d driven by Animation or Animation driven by Box2d or a mix of two like in my case. Anyway your solution is simple and clean ! well done

bye

Hi ! Today I've played around with box2d and i have manage to have a pretty cool result but not the fanciest i think. I read in box2d forum thath fixture could change their vertex posistion and this is allow also in Jbox2d. So I basically change fixture as skeleton moves and also when it is fillpped all the fixture is automatically flipped . Here is the code ( i'm using bounding boxes but it should be the same ) :

//Creation of the player body
for(Slot s : skeleton.getSlots()){
		if(s.getAttachment() instanceof BoundingBoxAttachment){
		     BoundingBoxAttachment attach = (BoundingBoxAttachment) s.getAttachment() ;
		     

	     PolygonShape poly = new PolygonShape();
	     float[] vertices = Arrays.copyOf(attach.getVertices(), attach.getVertices().length);
	     
	     attach.computeWorldVertices(0, 0, s.getBone(), vertices);	    
	     for(int i=0;i<vertices.length;i++){
	    	 vertices[i] = vertices[i]*GameScreen.WORLD_TO_BOX;
	    	
	     }
	     
	     poly.set(vertices);
	     
	     Fixture fixt = box.createFixture(poly, 0);
	     fixt.setUserData(attach.getName());
	     poly.dispose();
		}
		
	}

and in my AnimationUpdate

if(bodyMap.has(e)){
			Body b = bodyMap.get(e).getBody();
			float x = aComp.getSkeleton().getX();
			float y = aComp.getSkeleton().getY();
			for(Fixture f : b.getFixtureList()){
			    Object safe = f.getUserData();
			    if(safe instanceof String){
				Slot findSlot = aComp.getSkeleton().findSlot(f.getUserData() == null ? "" : (String)f.getUserData());
				if(findSlot != null){
					BoundingBoxAttachment attach = (BoundingBoxAttachment) findSlot.getAttachment();
					 float[] vertices = new float[attach.getVertices().length];
					 attach.computeWorldVertices(x,y, findSlot.getBone(), vertices);
					     for(int i=0;i<vertices.length;i++){
					    	 vertices[i] = (vertices[i]*GameScreen.WORLD_TO_BOX) - b.getPosition().x;
					    	 i++;
					    	 vertices[i] = (vertices[i]*GameScreen.WORLD_TO_BOX) - b.getPosition().y;
					     }
					     

				  ((PolygonShape)f.getShape()).set(vertices);
			}
		    }
		}

	}

I know this solution hasn't the highest performance ( even true in my game i didn't see any fps drop ) but it works . There are also a couple of problems i.e. some glitches due to heavy forces on the player body or fast speed of the animation that cause tunnelling .. but I have not found a solution yet . please tell me if your able to solve them .

Bye

I don't know if this is appropriate to post this here but i hope you could help me anyway. This morning i was trying to export my libgdx project to android and run it , but i couldn't make it works. At start it raised this exception java.lang.NoClassDefFoundError: com.esotericsoftware.spine.SkeletonData . Then i checked all projects needed in order & export ( main libraries ) but it didn't help... what am i missing? :bang:

Hi guys , I have the old Spine ( zip version ) with license from kickstarter . How can i download the exe version ?
