<HTML> Lets say that I have my field full of deer. You remember the idea, 50 deer's wandering around a field, grazing, walking and running away from approaching people. <P>All these deer will be driven by the same program but there is no way for a program to know which deer noticed the approaching person first. <P>The aw_event_set(AW_EVENT_AVATAR_ADD, function); allows me to set a function to be called if an avatar approaches the bot within some distance. The function called is not passed any arguments to indicate which bot noticed the approaching avatar. <P>There should probably be a "void *instance" parameter passed to the function to indicate this. <P>It will not look good for all my deer to run away at the same time. <P>Edward Sumerfield.</HTML> roland vilettOct 9, 1998, 2:50am
