Hey, it's me again.

This time with realtime environment destruction.

Imagine you have a city... and you have an angry Gyrados or Godzilla or some other giant monster from a video game or movie series.

And that Zilla-like monster goes on a rampage. It shoots its Mega-death-beam. Buildings collapse. Yea. That kind of thing.

Well, I managed it in realtime. Here's a screeny:

{"name":"608360","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/9\/e\/9e6c23b5243c92db1a6401f8766bf437.png","w":960,"h":540,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/9\/e\/9e6c23b5243c92db1a6401f8766bf437"}

And another after I level the building:

{"name":"608361","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/5\/d\/5d9a7aec2d665ae300ef0afc39d7c46e.png","w":960,"h":540,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/5\/d\/5d9a7aec2d665ae300ef0afc39d7c46e"}

What do you think? Why not try it?

'1' shoots a beam where the mouse is. '2' shoots a beam as in the first screenshot. Left mouse button rotates, right zooms, and middle pans (when moving the mouse, of course).

Feedback appreciated!

Your program opened a window with no content and then closed. Here is what the error.txt file said :

What graphics card do you have? Does it support OpenGL 3? If so, are the drivers up to date?

I'll have to enable some debug stuff later and you can try it again, if you want.

My laptop uses an integrated ATI Radeon X1270 graphics card on a Gateway M1617 laptop. I can't get updated drivers because gateway doesn't offer them and nvidia doesn't provide laptop drivers.

What version of OpenGL does my laptop support? I don't know, and the last time I tried to run that opengl version viewer program it just crashed hard.

Sure they do. But nvidia drivers don't support radeon gpus. AMD also provides drivers for laptops, but the latest drivers may not support your older radeon. AMD likes to drop older hw rather quickly.

Works on my pc. Really cool stuff!

So it's Rampage in 3-D?

That being said, great implementation and good luck on your future work with it! I'm sure you can come up with some pretty cool story/plot ideas to take it from tech demo to true gaming experience.

I meant to say ATI, not Nvidia. And no, I can't use their drivers on this laptop. They have to be customized for it first by Gateway and Gateway is too lazy to offer updates on this laptop's graphics drivers anymore (at all to begin with).

Edit - OpenGl extension viewer says I only have OpenGL 2 installed. :/

Really REALLY nice, but on my system it ran quite sloppy at a 09-15 FPS range, was it expected?

Specs:

- MS Windows7 SP1 64bit
- Intel Core i3-2330M (on a laptop) processor @2.20GHz
- 4GB RAM
- Intel HD graphics 3000 integrated GPU

BTW is there some sort of procedura debris "formation"? Or are all the same? due to the sloppiness I couldn't quite see it right.

Thanks everyone!

pkrcel, the debris is procedural. As far as the sloppy FPS, it's because I hadn't optimized it. I was making upwards of ~1000 small draw calls for the shards. Since I posted it, I've optimized it quite a bit, and now all the debris is drawn in one call. You can try this version, if you want, and see if you have significant FPS gains.

What language are you programming it in?

Judging from Edgar's crash report (and the spine-csharp.dll): C#.

Very nice, the second version runs much smoother than the first.

As Vanneto deduced, it's written in C#. I use a lightweight P/Invoke wrapper around Allegro 5 to create the display and handle input. Other than that, it's in C#.

The other bits and bobs include my graphics framework, which is based on modern graphics programming and is API agnostic (heck, I've adopted a few DirectXisms from working with XNA in the past). I don't support low level operations, just the basic "Here's a mesh, render it using this material to this render target."

Similarly, I use a custom game-engine-thing for the actual grunt of the non-graphics work. It's only for personal use, but it speeds up my game development quite a bit, when I can just pull code from other projects.

Vanneto, I'm glad to hear it runs better. I've made a few more changes since then. Just now, I finished optimized my loading code and get 60 FPS almost right off the bat during loading. Before, there was a flaw and loading would drop the FPS even in the loading screen... and thus cause delayed input, etc.

The new version runs SLIGHTLY smoother (~39FPS peak, 17PFS when all debris) but I also am on a different machine:

Specs:
- MS Windows 7-SP1 64 bit
- Intel Core i7-2670QM (a laptop...again )
- 4GB RAM
- NVIDIA Geforce 610M 2GB

I get a minimum of 12 FPSes with the integrated Intel HD3000 GPU, for the record...which is still a bit sloppy but more manageable than the previous 9 FPS.

ANYWAY I've seen that the debris are procedura but they seem cut out of the same shapes/volumes...well in any case it is really REALLY neat, props for this work.
