Long time since I was the last time in this forum. Nevertheless, I worked a lot on my game.
Here a short clip about a free fall animation. Superhero landing coming up 
Actually that is the next refinement to add a 3 point superhero landing. But I fear it will not be really visible, but anyway I will give it a try.

2 weeks of hardworking on something with no Wiki , even java docs , the New animation system (probably covered everything ) including :
- AnimComposer
- AnimClips
- TransformTracks
- Armature & Joints Nodes
- BaseAction & Tweens
- BlendableActions , ClipActions & Actions
- Emitter , Audio & Model (Concretes of HasLocalTransform) in parallel , sequence or sineStep Tweens
- Multiple AnimComposers on the same Model.
- Pause , resume , play animations as AppStates
Here’s a video of the progress , probably have finished their basic documentation , I will finalize the work & send here for review , before doing a PR or looking at the wiki :
Notice that this app uses JmeSurfaceView on a androidx.appCompat.Fragment.

This week I’m working on a rigging tool that will let me (among other things) define collision shape hierarchies for animated models in a way that is compatible with the MOSS custom physics engine.
I may end up with multiple layers to more easily balance between regular walking around physics (like in this picture) versus “which body part did the sword cut off” physics which would require a more complete hierarchy but otherwise wouldn’t need to be updated from frame to frame.
Still 100 open questions left to solve but progress is progress.

Is that a fixed mesh/model, or an isosurface/smooth voxel?
A good old mesh. I only use tris and quad. Moving more towards quads recently.
In the last few days I worked on an Arkanoid clone just for fun. It’s freely available for download on itch.io. Have fun!

in this case you need search “Topology” keyword.
Topology is very important.
But if you want skip making face, just download MakeHuman and export it and edit if you wish.
Oh, yes I know. I’m using correct topology. If you pay attention my quads are not placed randomly, they actually follow a pattern.

Working on a FPS & maze game (with way more success than my other wips)!
- Implemented a custom movement framework using raycasts (thanks @yaRnMcDonuts!)
- Random grid maze generation
- Shootable enemies
- A solid environment that doesn’t fly apart as soon as you shoot it.
- Runs at 60 fps!!!
To do:
- Fix sticky collisions
- Implement a minimum range of the gun
- Better models (gun and enemies)
- Barrel flash
- Fix gun orientation
- Bullet holes in walls
- Set gun to semi-auto
- Add reloading?
Yup, a lot more to do!

Continue working on my tower defense game.
What was implemented after the latest report?
- New weapon model
- Preview of a weapon on creation
- Weapons now has an attack range
- Algorithm for next attack search
- Weapons rotating to the direction of attack
- Total score for the game and adding points to it on enemy death
- HP for cave and last barrier (in this case door) as a target to protect
- Some other fixes
Of course, a lot of things need to be done and a lot of ideas in my head, so continue working on it 
Comments and advice are appreciated

Hello everybody,
I’m updating some old experiments with the cinematic package and the old animation system.
I hope to try all the upgrades to the new animation system when the next jme-3.4.0-alpha8 release comes out.
I wrote my custom class on the example of that AnimationEvent to prevent the animation from being reset at the end of the cutscene.

For the sliding door I used a RigidBodyControl in kinematic mode and 2 animations created via AnimationFactory.
Spatial door = ...;
addBoxCollider(door, 100f, true);
SlidingDoorControl control = new SlidingDoorControl();
door.addControl(control);
public RigidBodyControl addBoxCollider(Spatial sp, float mass, boolean kinematic) {
BoundingBox bb = (BoundingBox) sp.getWorldBound();
CollisionShape shape = new BoxCollisionShape(bb.getExtent(null));
RigidBodyControl rgb = new RigidBodyControl(shape, mass);
sp.addControl(rgb);
if (mass > 0) {
rgb.setKinematic(kinematic);
}
physics.getPhysicsSpace().add(rgb);
return rgb;

I used classic triggers to identify the player’s position in front of the door panel or behind the enemy.
In the example of stealth kills, I tried to create some movement with the camera, whose dynamic position is calculated based on the orientation of the player and the enemy.
