Object Interactions

I mentioned before the possibility of having two objects occupy the same space, and that, at least for now, I'm not permitting it. However, when object attempts to move onto the space occupied by another, or when two objects are adjacent, it is possible for these two objects to interact. For instance, there is the capture of an opponent in chess, picking up an item, landing on a trap or colliding with a monster, in adventur-type games. There are any number of rules that describe what happens when objects interact, and in a virtual world, action at a distance is also allowed. Typical examples include when one or both change their state or properties, and when one or both is destroyed, or even when one is created. An important type of interaction is the collision. I'll deal with this in more detail later, but wanted to mention it along with other types of interactions.
