Update to Kodji's Player Swimming/Drowning code 

By Bob

REV 2 (2-21-00)

I am sending code for adding a player drowning to GTest code. This will help give some ideas for using the detection of contents to others. The original code was from Kodji, I added a few updates to give it some more effects. With the original code the player would not die if the health ran out while in the water. This code change works well in my modified Gtest code that I use for testing.

Thanks.

In Gmain.h around line 92

#define SOUND_INDEX_WATERFALL       31

In Level.c around line 104

GenVSI_SoundIndex(VSI, SOUND_INDEX_WATERFALL, "Wav\\Waterfal.Wav");

NB : you must add a variable in Gplayer.h

Float       TimeInWater ;           

Also you must add a water sound to your /wav directory called waterfal.wav

Or just kill/rename that part of the code.
