As you follow the instructions below, click on an image to enlarge it.

Then use the'go back one page' arrow in your web browser to come back to this tutorial.

Loading the World

Open a new world, with the template of your choosing. Save it in a directory that you can find again, and then start Alice and open the world. NOTE: You cannot double-click the file to open it; Windows will not know what to use, and even if you select Alice from a list of programs, the loading will fail.

First: After you have opened the file, and set up your world, go into the "Layout" mode by clicking on the green button 'Add Objects' (toward the middle of screen)

Click 'more controls.' Click 'drop a dummy at the camera.' Rename the dummy 'originalPosition.' To leave the layout mode, click 'done' This is something you should always do when you make a world in case you need to return the camera to this view later. If you don't understand dummys,look at the camera control tutorial again.
