Hi,
Just implemented life spans for the various creatures in the game. Each creature have their own attributes such as health, age, aggression, if the can drive vehicles, if they can be pets etc. What I've done is to make them get older, thus their age changes which can be viewed when clicking on a creature. The age increments in line with a day/night cycle and when the said creature reaches a certain age, they pass on. Now, this certain age I've set for the various different types of creatures, thus rabbits don't live as long as crocodiles for instance. I'm thinking of making all this customizable at some point allowing the player to change attributes of each creature.
Looking at implementing some visuals to show the different aging of the creatures today if have time and then adding more dangerous creatures to the lower levels of the underworld in the game...
What is gained by having age as a stat for creatures? Are there systems that require dead creatures or breeding?
