Welcome back! If it's not already open, let's go ahead and reopen the MyFirstGame scene by opening the Builder, finding it in My Library, and dragging it into the scene. Now that we're back, we're going to move forward with creating an on-rails shooter, so let's get started by adding some rails to our scene.
We are going to use these track sections to design and lay out the track for our shooter. We can play around with this track segment and get a feel for moving it around. Currently, we can click and drag the object around and use the scroll wheel to move it as well. For more precise control, when an object is selected, axes will appear that will allow us to drag the object around. Also, to make the object fall to the ground from above, we can click the Drop button.
Once we have a feel for movement, we can also play around with rotation. If we click on the Rotate Tool at the bottom of the screen (blue cube with green arrows curving around it), we can use the mouse in the same way to rotate the object around. The blue ring that appears will be the best tool for rotation: it will rotate the track's direction, leaving it wherever it is on the other two axes of rotation. We can always switch back to the Move tool by selecting it at the bottom of the screen (blue cube with red arrows coming out of it).
Once we've laid out the whole track, let's save our scene as it is, by going to the File menu and selecting Save. Now that we have the track saved, the next step is writing the script so that we can ride it. Let's give it a try.
