Water physics

[motorsep]

Can someone on TDM team, familiar with the water physics code weed out water physics code from TDM codebase ?

Comment this line in Game_local.h and rebuild:

 

// enables water physics

#define MOD_WATERPHYSICS

[motorsep]

Oh, I don't mean to disable water physics. I mean to diff the code for water physics to make it available for general modding of idtech 4 engines.

 

Would I be able to find all the water code by #ifdef MOD_WATERPHYSICS ? Are there any parts to it that aren't #ifdef'ed ?

I can't say whether that would give you all the water code. There's certainly a lot of places where it's partitioned off this way. There are lots of checks for whether the content of a spot is water (i.e. to change whatever happens at that spot), and I don't recall if they're partitioned, but searching for "water" should show you where TDM cares about water.

You should be able to diff the source files from this mod:

 

http://doom3.filefront.com/file/Water_Physics_Mod;41449

 

to get just the physics changes.

Supposedly that isn't complete water physics mod. Rumor has it TDM has better water physics code.

[nbohr1more]

Yeah, this is probably true since the author of that mod worked with the TDM team. However, if you diff this mod against the Doom 3 SDK then again against the TDM

source you can probably identify most of the code changes. I would suggest that you use an older TDM build such as 1.02.

oh, what's wrong with using new TDM ?

[nbohr1more]

Nothing if you don't mind doing a lot more searching. The older codebase has far less code to search through.
