Post Topic: Change terrain C++ code  Posted 24.03.2012, 20:14 |
Good afternoon, I was wondering in which file is the terrain code included?
I'm thinking of making it deform in real time, hence I need to know where its code lies.
Thanks for your time.

Its in the part of the engine that is not accessible for SDK users.

Indeed I too though of that, but according to CryEngine's SDK FAQ ( files/CryENGINE_3_Free_FAQ.pdf): Quote: 2. Is it the same Engine Crytek use in their Games?
Yes, we'll be giving you access to an up to date version of CryENGINE 3 − the engine we use, the engine we give to our licensees and the same engine that powers Crysis®2 and Warface®. This will be a complete version of our technology including C++ game code access, our content exporters, script samples, new improved Flowgraph and a host of great asset examples, which will allow teams to build complete games from scratch for PC.
"be a complete version of our technology including C++ game code access" , guess they mean access to the game's C´++ core, not to the engine's.

Quote: be a complete version of our technology... Binary version (DLLs). Quote: ...including C++ game code access Gamelogic Sourcecode. Releasing the full engine sourcecode for free would be a bit...too much i think.

It is an interesting question though, with CryEngine being all "realtime all the time" you'd think terrain deformation would be right up your alley.

Indeed BmB, there are two issues with it:
1st - It can't be used by the current technology which most users have, only by what is the current top of the line in terms of hardware, perhaps in a couple of years its doable for most users.
2nd - Replicating that info over the network is a pain in the butt since there are major security issues with it.
Fortunately my team and I are thinking of implementing this and we've already came across a good reliable,efficient and secure solution, but useless to be used for now ^^

It is (the terrain system supports modifications on the fly, even in pure game mode). It was even used in CryENGINE 1 (FarCry). Never really used afterwards though. Still "realtime all the time"

Code: ITerrain::SetTerrainElevation(int x1, int y1, int nSizeX, int nSizeY, float *pTerrainBlock, unsigned char *pSurfaceData, uint32 *pResolMap, int nResolMapSizeX, int nResolMapSizeY) looks like it ought to do what you want. Not entirely sure on the parameters however. You can access the terrain via gEnv->p3DEngine->GetITerrain() (though note that some terrain stuff is done directly in the 3D engine).

You should be able to place decals via FG...

[quote="NeoLegends] Battlefield 3?! BFBC2?! ru s even on consoles[/quote] True NeoLegends, but its done at a very small scale, terribly limited and in BF3's case, they had to 'hack' their way through, which created a ton of bugs which even today are present. Most of them got eliminated in the Beta - Operation Metro, I'm sure you're familiar with the bugs - but some remain, due to the fact that its mostly a hack instead of a feature.

Well as far as I know the biggest problem is hardly performance (hl2 originally had terrain deformation but it was scrapped after the leak and all that) but rather the fact that you usually have a bunch of data tied to the terrain, lightmaps, decals, detail objects etc. and deforming it would make the level look very weird indeed because that data can't follow the terrain.
