It looks alright, the only thing I would comment about, is when the huge pillars fall down, they just stop when they hit the floor. There should be some kind of a resultant force acting upon it.

But else it is good!

PS. Did you develop it yourself, or is it an external library?

Thank! Actually, the object in that video or not dropping, just popping into existence. I want to add a shader with some nice effects for that, but I have no time right now for pure cosmetic development.

For physics I'm using BEPUphysics (http://bepuphysics.codeplex.com/). This handles all the basic stuff, but for a good behaved world I found that I need a lot of extra code to determine insertion position and angle, collision detection and avoidance, response to non-natural physics interaction, application of extra forces and triggers, etc.. Everything is far too math heavy for my tastes but I can manage .

The camera shaking should be based on the distance from the falling rocks.

Why don't you share the EXE? I want to shoot some rocks

I do weekly snapshots with the latest and greatest code on my blog: http://dwarvesh.blogspot.com

I was going to ask the kind forum here to take a look eventually, especially after snapshot 12 which I plan to make very polished and user friendly, but feel free to take a look right now if you feel like it. You'll need .NET and XNA 4, a XNA HiDef compatible video card. I'll eventually add a version with lover video specs needed. The engine boots up using high quality settings, but you can tweak them from the options menu. The controls are a bit weird with pretty much every key doing and action or having a debug function and Ctrl is as a modifier key. You'll have to wait a few snapshots before I can implement a friendly in game UI. While the in game UI is bad, the modding UI is pretty decent.

If you do take a look, please tell me what you think. Starting with if it actually launches or crashes on your system . And how it performs. On high it can be pretty demanding, I'm struggling to get over 200 FPS on GeForce GTX 660 Ti. On "Ultra" should run at about 130 on such a system in 720p. But setting things to "low" I can run it on an Intel onboard at 640x480 at 60+ FPS, even with a few effects.
