Re: How does the agent know other's information?

[Rick Riolo]

if i understand your question, then
building on the codes below, one could just do this:

  id otherBug;
  ...

  if ( (otherBug = [world getObjectAtX: newX Y: newY]) != nil ) ) {
      [otherBug getHaveEaten];
      ...
  }

assuming the Bug's have a getHaveEaten method, of course.

In general, the approach is to
   = get the address of the other object, by whatever
     is the approapriate/convenient scheme
   = send it a getXXX message to access its value for XXX

  - r
