Architecture Diagram and Debugging Output?

[Ghost.b88]

Hi, I looked around at the site and source code a bit yesterday, and I found some really good design docs (engine documentation, AI, etc.) that describe how the game works. However, I am wondering if there is an architecture diagram of some sort, something like class diagram and sequence diagram? Something in Visio, for example. I want to see how the components / classes / objects interact with each other, and the relationships they have with each other.

In addition, how do I get the debugging output or log files? anything text that describes the actions and events and errors that are happening when I am playing / profiling the game?

Thanks in advance.

There aren't any diagrams like that. (There's this for the simulation components (blue lines for components directly calling methods on others; red lines for components broadcasting messages that are indirectly received by others) but I'm not sure how much that really helps )

Some debug output (via debug_printf) goes to stdout (on Linux/OS X) or to the Windows OutputDebugString system (shown by the VS debugger, or by DebugView). Other logging (via LOG macros from ps/CLogger.h) goes to ~/.config/0ad/logs/mainlog.html or %appdata%\0ad\logs\mainlog.html

(But be careful about the VS debugger: it seems to make OutputDebugString extremely slow, which will mess up any profiling. I don't think DebugView has that problem.)

Thanks. This will help me understand what the game is doing.

How come some components are circled in green?

And send my regards for the person who created this, it's quite impressive!

Green ellipses are for components implemented in C++, black ellipses for components implement in JavaScript. (source/tools/cmpgraph/ is what generates this.)
