Well the simplest way is just to rotate the object/sprite towards your player and move it forward.

My computer surpasses all the technologies of the day. What computer do I have?

Prepare actions for the enemies for what they should do in different cases.

1. walk around when player is out of sight
2. attack when within a certain distance
3. chase for a while if player flees away

I absolutely have no idea how a chocolate bar would attack a soda, that's up to your imagination

I'm thinking huge chocolate bars that grab the soda-player and pour out their soda... if all if it pours out their dead.

So would i use the Yrotate object and move object command to have the bar face the enemy?

Also what commands do i use so that it follows/attacks the player?

Oh so we are in 3d... well yeah that's a nice basic method, though used a little more cleaverly. You should store the X and Z axis in variables, then use POINT OBJECT to face the player, and then restore the X & Z rotations so only the Y is really affected. Though of course you don't need this in the case of a flying type enemy.

If you are close enough, they start rushing at you, if you get out of their sight, they are back to their idle behavior.

what's FPI?

I think you should go over some tutorials first...

Check out this thread:
http://forum.thegamecreators.com/?m=forum_view&t=115633&b=7

This tutorial by Zotoaster:
http://forum.thegamecreators.com/?m=forum_view&t=63411&b=7
really really helped out my understanding of arrays and types.
[edit]
(its a basic AI tutorial)

No. DBPro is a programming language designed for games, but it's not a "game generator" tool. As far as DBPro is concerned, it has no idea what the player object is, how an enemy should move, or what an attack is - These are things that you have to program yourself.

For example, you'll need to use the math commands so that you can determine what the angle is between an enemy and the player, you'll need to move the enemy object towards the player if the player is in sight, and program your own "attack" in once the player is in range.

What should an attack do? Well, it will probably kill the player or take away some of his health, depending on how you want your game to be. Again, these are things you'll have to program yourself, there are no built in functions for things like this.
