Items the bot needs in order to get Collision detection: 1.Object registry data. 2.Object data for area within 120 meter radius. 3.Way for the bot to comprehend this information. 4.Optional, Some way for the bot to get the avatar's relative size in = relation to local objects. 5.Optional, You know how Preston downloads midi's and then get's the = time for them someway to get at the rwx files and the bot to kind of = render them without it visually taking place. Steps to make collision detection. 1.!IMPORTANT! Get registry and Object Data loaded to the program for = active use, possibly setting as a string type thing or something. 2.Get the bot's position in the world. Have it query within 5 meters of = it's location for any object and have it check the registry to see how = close the bot is to the object. 3. If the bot is within the bounding box of the object then have the bot = declare something like "Ooopppps" or something. 4. If the bot is not within the bounding box of any object, excluding = floor tiles, then have the bot continue with no error what's so ever. = This would probably use very little code and not be so hard on the = memory of the bot or bandwidth so it could be done fairly easily and = constantly.

Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit What you speak of is a bot that would know if an AV touched anything, but that usualy isn't needed. At one of the tech talks i asked Roland about maybe adding a comand to the object description that would send an event with the AV's name, or sesion #...whatever....he said this wasn't posible..because the browser would have to konw every object arround the av, and it's size...but i got to thinking, and i could solve the problem with some simple code....all you have to do is constanting check the AV's position, and compare it with the object you want to know if they bump....obviously this would only work for a few objects..it would get way to repeditiv if you tried to do everyobject....but for certin games and things, where there only one or two players, it would work just fine. Take a look at Faber's CYPac....i belive that in compares the co-ords of the bot that is chasing you to your own co-ords....now, i may be wrong...but that would seem logical, wouldn't it?
