I thought it was about time YOU did some of the work! So, just start the project and follow the instructions... This is a bit rushed out before the Scratch update, and the website goes down, but hopefully the tutorial will mostly make sense... :) It takes about 15 mins to go through all of it, but when you do, you'll find out just how easy it is to begin to create a 3D project. And once we add a few final steps (near-surface clipping, filled surfaces, distance ordering, plus pen-saturation control), it'll look really great :D
Thanks to MrLog for the idea of using Scratch & Gobo to guide you through this tutorial :) The hardest part of using this engine is creating the initial structures (i.e. the objects/characters/ships/etc. in your game). I'd suggest using Blender to design your structures, export it as a .obj file, and then read it as a text file to see the appropriate points, lines and surfaces, as needed below... Using the blocks in the Setup Structures sprite, a particular structure is usually created like this: 1. start a new Structure, with some initial XYZ location; 2. define Styles (colour,width,shade) for various parts of your structure (you may have some styles already defined beforehand for this structure because you want them common to different structures); 3. create the XYZ points that will make up your structure; 4. create any surfaces that will be part of the structure; 5. add components to your structure (lines, volumes, dots); 6. end the structure. Now, go to the "Camera" sprite and use the blocks in there to control how the camera behaves - the blocks should be fairly self-explanatory. Since you also have the structures you want for your game, you can now go to the "Move Structures" sprite and use the blocks there to control what they do - the blocks are pretty similar to the ones for controlling the camera.
