Hey, i use A6 and i was wondering the same thing. But the only difference is, I found out how to do it. All i had to do (took me about 20 minutes to find it) was go into the War.wdl file and find the State_die() (i believe it is) and in it you have to look for a line that basically plays the Death animation. It took me a while to find this because it was worded akwardly. Any way, right before the death animation is played, i put this code:
ent_create (health_pack, vector(my.x,my.y,my.z), medipac);
This snippet of code creates the health pack right as the player is dying. The only problem i have with this code, is the health pack floats in mid air. I have absolutely no experience with the physics engine so i don't know how to make it fall properly.
