does anyone know how to change the camera, also haw do how change the actual objects?
O.k., that's mostly done using the right mouse button. To select an object (Or the camera) right click it, now it will be highlighted with pink outlines. Then click and hold the right (Or left, I forget which, I haven't been on my computer in a while) mouse button anywhere in the 3-D space window and draw a line. You should be able to move the object by moving your cursor. Simply click to let go. Draw a circle to rotate the object. And if you want to move in one direction specificly, right click and hold one of the arrows and it will only move in that direction. As for changing objects, do you mean adding more objects, like a sphere or something? If it's that, have your cursor in the 3-D space window and press the space bar. A menu will pop-up, additional objects, cameras, lights can be found there. Once you find what you need, left click it and a more specific menu will pop-up with options for the object before its put in. One thing you'll have to remember about Blender, is that to use it successfully, you must learn the keyboard shortcuts. It can make things a lot quicker.
Edit: I'll add more info later.
