How I make an AI Enemy?

Well, (i´m new in this, sorry if I put these on this on the incorrect forum) I want to make an AI of an enemy who chase and kick the player (not shooting), but i cannot do it, I try with some scripts I found on internet but they doesn´t work, they only chase me. So please, if you know about a Scrip do what i want, you can spend me?

 

So which one is it?

If you want to make an AI then what you need is to learn programming which will allow you to do anything you can imagine.
You can start here: http://unity3d.com/learn/tutorials/modules/beginner/scripting

Even if there is a script that does what you need laying around internet it's hard to point to it since you didn't give any details on your implementation like for example: what does it mean to kick?

Idea that you can find scripts that do exactly what you need is unrealistic unless it's a very generic / abstract / common problem - not at all like gameplay elements. Idea that you can put a game together with some chunks of code found here and there is just false.

If you're looking to do some programming work without programming then you can try things like visual programming like: http://www.hutonggames.com (haven't treid it myself but it suppose to be good). It still requires you to understand what it is that you are trying to do and setting things up etc.

If you're looking to do some game development work without doing any work (other then asking around for finished solutions) then you're out of luck.

 

With kick I mean some enemy to approach and attack, not an enemy who atack being far, Thank you for links, i not understand very much of the scripts (How I say, im new in this of programming, the only thing I do its for a Minecraft map)
