UT2003 Function history (Howd they do that?)

Ximmer · 2002-10-24T11:26:55

In UT2003 (Unreal Tournament 2003) when I get a crash I get an error message that states the nature of what killed the game. But underneath this description theres a Function history of Where this crash occured... So seeing this I thought to myself "That''d be a great thing to add to my engine!" And so I did. And I did behold that my framerate proceeded to die... on further inspection by running it through the VC6 Profiler in Release mode the 2 functions I used were taking up a very large portion of the Cpu time. (Usually within the top 5) These are the Methods I tried... void MyClass::MyFunction() { HistoryStart("MyClass::MyFunction"); // Do Stuff in Here HistoryEnd(); } this one was by far the worst as I had to copy the string into a new memory location and then add it to my Linked List of Function Names. void MyClass::MyFunction() { static const char s_History[] = "MyClass::MyFunction"; HistoryStart(s_History); // Do Stuff in Here HistoryEnd(); } This one was better as I could avoid a call to new and delete... but it still had a Massive impact on my framerate... __inline HistoryStart(const char *FunctionName) { // Add new Node to Stack } __inline HistoryEnd() { // Remove Node from Stack } void MyClass::MyFunction() { static const char s_History[] = "MyClass::MyFunction"; HistoryStart(s_History); // Do Stuff in Here HistoryEnd(); } This method produces some pretty good results... It finally got HistoryStart below the #1 Cpu user slot... but now it''s in the #2 slot... Can anyone think of a more efficient way of doing this? -Ximmer

Heh.. .thanks for the input guys, I''m already thinking of ways to implement this that''s safe for recursion (cause I don''t think you can do it statically and also have recursion).
