Your english isn't the worst I've seen, so no need to apologize.
There have been many requests for this, and since you're new I'm gonna go ahead and tell you this one time:
There is a search function at the bottom of the forum page entitled "Forum Search", use that to search for something like "better AI" or just "AI" in general.
It is highly recommended that you do this type of search before posting a request as it will keep the forum clean by not having repeated threads such as this one.
[EDIT]
Also, just a heads up but to HELP the search engine used in the forums to work better, I would advise taht you continue to title your request threads in a detailed manner as you have already displayed, it pains forum dwellers to see threads titled something as useless as "Help me!" or "I have a question" when that doesn't tell us what the thread is about nor will it help people to find that thread later on down the road.
So keep the subjects detailed to what is within their corresponding thread.
Keep to those rules and you'll do fine here.
Welcome to the Forums!!
