Do not double post the same question in different forums! This is the wrong forum, too.

Sorry, i just wanted to get an answer from different minds. Im new to programming.

What you would have to do is show a panel or a 3d model or what ever to have the player select from, then on the click function of the button they press, you would have to create the entity through a function and set up the physics or what ever through code and place the vehicle in the level at a position through a vector.
