In the context of the Carnivores series, "AI" usually refers specifically to the numbers found in _RES.TXT in the "ai" field of an animal's data block. The hunter has an AI value of 0, ambient animals have AI values between 1 and 9, and pointable animals have AI values between 10 and 18. Each value corresponds to a routine in the source code that determines the order of animations and sounds in the animal's CAR file, which animations and sounds correspond with each other, and what behaviors correspond with each pair and what triggers them. Despite the fact that several of the animations and sounds are common to nearly all the animals found in the games (such as those for walking, running, and idling), their order often differs between animals, meaning different AI routines are not usually compatible. As a result, messing with AI values can in the best cases result in humorous effects in-game, such as an animal repeatedly dying in-place, or in the worst case potentially cause the game to crash.
