Deathmatch AI

poorcollegedev

Hey guys, I need help conceptualizing or mapping out an AI system for enemies for an arena based deathmatch mode. They would need to roam around the map until they see an bad guy (either player or computer). Could this be achieved via waypoints. By that, I mean have the enemies randomly move between waypoints set throughout the map and if they come across an enemy, go for it. Any ideas??

Here's a nice random movement I made just using a couple of equations.

That's neat, @Socks! I will make it Awesomatic immediately. :-)

@Socks hey buddy, that"ll be a good start! How would I keep it inside a set boundaries in the arena?

your demo seems pretty cool but the box follows the same path each time...

Well not quite but it does stick to a similar path, you can change the value to make it more random (pseudo-random) if you like.

Hold on, let me work that out . . . .

Here try something like this:

You could make the randomness a bit better with some time and effort, but as a general idea I think this could work.

Here's a very random path - but this is a wrap around one:

Here is a different kind of AI movement. This is a basic model of chemotaxis -- the way single cell organisms, like e-coli, seek (or avoid) things. The basic idea is that the organism always continues in its current direction until it senses that it is getting further away from the desired object. Then it randomly tumbles and starts off in a new random direction. It is amazing how efficient random-walk chemotasis can be, given the fact that it's umm -- random.

For background on chemotaxis, see: http://www.mit.edu/~kardar/teaching/projects/chemotaxis(AndreaSchmidt)/index.htm

COol ! (I might steal that) !! Good article too, very interesting.

There is also a scientific underpinning to my 'random' path ( http://www.mediafire.com/?4c2z2jw8bbweh9r ) it is closely modelled on the route I took home last Thursday night after the pub closed.

@Socks -- glad you are back in the game!

@poorcollegedev -- are any of these ideas what you are looking for?

if you need it to be appear more random, make more sets of your path constraints.
Then use an integer to define which random path to take.
so when game.randompath = 1
change destination to waypoint1 X & Y
when game.randompath = 2
change destination to waypoint2 X & Y
then if you want to add another level...
make your waypoints randomly select coordinates from a table, or have them move, and follow way points themselves...

any single suggestion or combination of what has been offered here by myself and others should work great!
Otherwise more details will help us help you
