Hi Guys, Just want to bounce an idea I have for Wall detection around. It seems that most everyone has gotten used to the current wall detection setup, but I think it doesn't make much sense. I may be interpreting wall detection completely wrong so this may be a completely moot point. Why can we only see one wall at any given point in time if there are actually two walls in our FOV? I think that walls should be reported at the point where they enter the FOV farthest from the Bot instead of on a perpendicular line. This will allow for two walls to be seen at any given time if you are headed towards a corner. I have a picture of what I am thinking as it can explain what I thinking better than I can in words .    The two red squares would be reported as wall locations by GetObjectInSight in the setup that I am thinking of, as that is where the wall enters the FOV at the furthest point from the bot. The red line should be ignored. Image Key ---------    - Darkest blue is the bot.    - Medium blue, FOV of closest objects (Item only visible if it has moved since last update)    - Light blue is current FOV (Approximation)    - Green arena boundaries (Walls) I know this may be asking allot and better off for the re-write of the Arena core (if and when it happens), but it makes more sense to me, and seems to follow human vision a bit better than the current setup. Feel free to include your thoughts . - Timothy S. edited for wording [edited by - slepyii on August 14, 2003 10:37:48 AM]

Thanks. This proves that I was interpreting what Kevin was stating about wall detection as being incorrect (actually just backwards), so yes, my red line is incorrect and should be ignored.

As for the idea of giving two points on the wall, where it enters and leaves the FOV. My initial feeling is that makes things too easy as you could easily tell which wall you were looking at. If only one point on the wall is given at any one time then it would require a bit more work internally by the bot (though not much) to figure out the orientation of the wall and where the corners of the arena are.

without changing the arena core, the most elegant solution is storing the walls'' coordinates, and writing a position detection algorithm, and check the coordinates against that values.

When I get around to writing my bot, hopefully soon, I''m not planning on using the walls, though things may change. I was just stating how I thought the bot using the current interface setup should detect walls. It makes more sense to me to be able to see the walls if they are in the FOV even if you can''t draw a perpendicular line from the wall to your bot.

Figured this would also give everyone a chance to discuss the wall detection setup as I have seen a few (ok, maybe more ) posts about the current setup.

I''m just curious, but how many people NEED the walls to orientate their bots? I''m only using them as markers so the bot knows not to run off the edge of the map, other wise they are useless.


Just thought of something. have an out of the ring area. so instead of a wall, its an area around the map that if the bot steps into they get disqualified, or loose maybe 1 health every frame (or maybe 45 frames - ie one second).

Also means we don''t have to worry about bumping in to the walls anymore

I have my bot detecting when there is nothing or nothing but a wall, in which case, it turns itself. The problem is, in wide areas, it won''t see the other bot between the wall and some object because my bot turns away to quickly.
