Hi, is it posible to create a 'hot zone' for mouse clic detection in that area? and another question... is it posible to detect a mouse clic over a 3D object?

This is for made the Option Menu of the game, for select the tipical options... New Game, High Scores, Load Game and Exit Game...

Yes... and yes

"Hot Zone": You have to implement it by yourself, check the position of the mouse every sync. //edit Of course, only when a mousebutton is clicked you have to check the area.

(is Mouseclick && is it inside the area? YES -> doSomeWikkidStuff)

"mouseclick over 3d-Object"
Same goes for mouseclick over 3d-Object.
I think dbPickObject will do a good job.
(at least this was the command I used for a similar thing)

If the user clicks a mouse-button then check with dbPickObject.
If it returns >0 you can do the item stuff.

ps: with PickObject you can provide a start and end ID so you
can check only your ID range for the Menu items which will speed up things (if you have other 3d objects that are not menu-options).

Here is what I do:

I always have a variable with the object where the mouse is. This allows me to do hover kind of action to highlight the current object.

The I have an IF statement that sends all the relevant data to another function.

Something like this:

+ Code Snippet

{
// Get the object

object = dbPickObject ( dbMouseX(), dbMouseY(), 1, 39 ); // 39 is the highest object I want to pick

// If the player hovers above a selectable object do something cute to highlight the object

if ( object > 0 ) myCoolHighlightFunction ( object );

// If the player clicks, do something

if ( dbMouseClick() == 1 and object > 0 ) myFunction ( object );
}

Hope this helps.
