The reason no one answers your questions is that no one CAN answer them. Look at this question: How do you make a mob help you out in the game?

Do you expect someone who knows nothing about your game to be able to answer that? We don't know how your game works, we don't know what goals there are, we don't know what "helpful" would even mean in the context of your game. In Super Mario World, Yoshi is a mob that helps out Mario. In Half-Life, the "Barney" security guard is a mob that helps out Dr. Freeman.

Do Yoshi and the HL security guard have anything in common? Nope. Can you imagine if the designers of those games gave the programmers this instruction, "Okay, make a character that helps out the main guy." Would the programmers have any clue what the designer actually needed? Nope.

If you want your questions answered... provide more information about your game, and provide more specifics about what you want. Also, stop double and triple posting. If no one answers your question the first time, asking the same question, the exact same way again, is not going to help.

Finally, bear in mind this isn't a chat room. You will not always get a response right away or within 24 hours.
