|A.I. Aritificial Intelligence . STEERING|
|The Artificial Intelligence is interesting
for all. Robots like Terminator, R2D2, DATA open from the cinema
the possibility of advanced Artificial Intelligence. But
are robots, like MARS ROVER that really use this AI . The MARS ROVER is a NASA bot , now is on MARS planet avoiding rocks, avoiding cliffs and looking for appropriate places to their secret purposes. Our Artificial Intelligence document will speak about this teme and how to apply it on ours games.
We can find three basics AI groups , The problem of physical movement , What graphic I need use to turn, to move a unit , etc .This group is called a LOCOMOTION or motor skills. The group that decides how to arriving to some point is called STEERING or task generation. The third group decides as using its abilities to complete their objective. This group is called MOTIVATION or action steering.
IF X.Targer.Position >X.Terminator.Position -----> X.Terminator.Position
IF Y.Targer.Position >Y.Terminator.Position -----> Y.Terminator.Position
IF Z.Targer.Position >Z.Terminator.Position -----> Z.Terminator.Position
Is very easy implemented the inverse algorithm to evading a enemy,
only change the +1 to -1.
The better solution "STEERING", is using a technique "PATH FOLLOWING" . On an environment 2D-3D the routes to arrive a target can be many. And some can be better that other, because in this route you can find a armor, life, because is the more sort route, etc. Or because it is not dangerous route.
But like the "path following" works, first you need create the paths, each map for separate. A path is compound by origin, a destination and a series of coordinates that indicate the route.Will we usually have an origin and multiple destinations, How we can know that is the best route?. Applying destinations values , this means that I need punctuated each "control point" or destination , in function for example that a door is open , that there are life, ammunition or anything.It is simple, but is possibly that using a graph we will understand more .
The figure 2 , is a path table , to walking around the map, we need making a physical connection among the corrects paths, for example to arribe form "a" path to
"w"path we need go by "b,e,d" or "h,e,d" or etc.., but the better route? , how I cand find? ,very easy , your need to give a path value he , and to add all the paths or contol points value, the more littlel value is the correct route.
