Hi
The source code is a bit messy but I have succeeded in detecting collisions between the projectiles and the enemies.
I assume you can read. I rarely post here several times per day, I post some updates. I don’t see any multiposts.
I don’t see the point, maybe I should sleep much.

Otherwise, I just tested the new version, with a little difficulty I must say because of a very slow framerate on my poor laptop (10 fps, sometimes it freezed completely) !
That’s my fault. It is very slow without my optimizations, I have not yet ported them to Ardor3D.

What I noticed (but I think I’ll teach you nothing) :
- I tried to take a gun, heard the pick noise, but hadn’t it and couldn’t shoot.
You have to pick the right ammunition and the right weapon. Of course you cannot use cartridges with the pistol. Use the scroll or some keys to select a weapon, they are indicated in the menu.

- The models are pretty cool !
Feel free to use them, they are under “free” licence(s). My skills with Blender are lower than yours :-X

- The black fog is too near !
Something is still wrong with the collisions between the player and the walls.

- No slide collisions on the walls (I remember it was implemented on old versions…) and no collision at all outside :’( .
You’re right.

- The outside scenery is beautiful !
I might move it into a separate level as it was just a test.

- Problem with the skybox, which doesn’t follow the camera.
I might move it too and I don’t use it correctly.

But you really improved the game since the last time I tried ! Now I’ll take a look on your sources ;D .
Thanks but there are still a lot of things to improve, it is even not as playable as the “old” alpha version.

Which fog? I couldn’t see any fog at all…(Core i7 2600K@4Ghz, 16GB, Java 7.something, GeForce 680, Windows 7 64bit)… ??? I agree on the sliding thing…once you hit a wall, you get stuck, which is very annoying and not what you would expect.
Yes it is really annoying. I implemented collisions with the walls very quickly, I will have to rewrite them, it is crappy and not accurate enough.
I have not yet updated the demo of the pre-beta version. I will do so when the source code is more beautiful.
Thank you for the feedbacks and sorry for the late reply. I didn’t notice your posts. There are obviously tons of wrong things in my game and it is still under development, I will take into account your comments.
