1. Make sure you have downloaded and installed Unity from the Unity website and once you open it you will see the default grey interface, with a number of windows open
2. First switch the Layout view from default to 2 by 3 by clicking the dropdown menu
3. The large window you see is the ‘scene editor’ and this is where you will add new models, lights and environments and be able to preview what is going on in your game
4. To rotate the view in the scene editor, you right-click the mouse and drag around to see
5. To zoom in and out, you use the roller wheel or scroll ball on your mouse forwards & back
6. To pan left and right, up and down, hold down the middle mouse button (usually the roller wheel) and drag the mouse in whichever direction you would like to pan
7. So the basic navigation controls in the scene window are rotate, zoom and pan.
8. Click File – New Project. Choose a location for your files and create a new folder for your project. Rename it and save your file.
9. Beneath the scene editor window, we have the Game window, which lets you test the game and preview what it will look like when you output, by pressing the ‘Play’ button
10. The Hierarchy window shows you all of the objects that are currently in your scene, such as cameras, lights and individual objects
11. The Projects window shows all of the objects that are available to you to use in your scene. These are stored in your assets folder, but they only become visible in the scene after you drag something from the project window to the hierarchy window or into the scene.
12. The Inspector window is where you can make changes to the objects in your scene. For example you could change the scale, position or rotation of an object or any other properties that it might have, as well as adding and modifying components to it.
13. Usually when making a game, you would create the 3D assets using 3D modeling software such as Blender, 3DS max or Maya
14. First of all, add a cube to the scene by clicking ‘GameObject’ at the top and then selecting ‘3D Object’ and choose ‘Cube’. You should see a cube in the scene and game windows and hierarchy.
15. Click on this or on the cube itself and its properties will appear in the Inspector window on the right.
16. You can move the object, you can rotate it and you can scale it. At the top of the scene window there are icons for pan, move, rotate, scale and transform. If you click each of these, notice that the gizmo on the cube changes (arrows for move, circles for rotate, cubes for scale).
17. You can change the object's properties by interacting with the gizmo, e.g. by dragging one of the arrows in move mode on the x, y or z axis. Notice when you do this, the properties in the inspector panel change accordingly. You can also type values directly into the inspector panel for position, rotation and scale under the ‘Transform’ component of the cube.
18. The keyboard shortcuts for the transform tools are Q for pan, W for move, E for Rotate and R for Scale
19. Press R and then flatten the cube and make it a bit wider. Reposition it at 0, 0, 0 by typing the values into the ‘Position’ boxes for X, Y and Z in the Inspector window.
19. You can view your object from different angles quickly by clicking on the axes icon in the top right of the scene window. E.g. if you want to see the x axis, click the ‘x’ and it flips.
20. Add a cylinder to the scene by choosing ‘GameObject’ – ‘3D Object’ – ‘Cylinder’
21. Rotate, reposition and scale the cylinder so that it looks like the wheels or tracks on both sides of the tank (it should be a little wider than the cube body of the tank).
22. Use the navigation rotation and panning to check the tank from different angles
23. Next we’re going to make the top of the tank, again using another cylinder. Add one from the GameObject – 3D Object menu and resize and reposition it on top of the tank
24. Add another cylinder from the GameObject menu and drag it out into a long thin cannon
25. If you have any issues with the positioning of these objects, just type 0, 0, 0 into the position properties of the Inspector window and they will snap to the centre of the scene. You should also check the tank from different angles by clicking top & side view
26. Now let’s organize the hierarchy window. First, rename each object to what it actually is, so cube should become ‘tank_body’, and the cylinders should become ‘tank_tracks’, ‘tank_top’ and ‘tank_cannon’ respectively. Now we will group them all together.
27. Click ‘GameObject – Create Empty’ and rename it in the hierarchy window to ‘Tank.’ Now select all of the other tank elements & drop them onto the ‘Tank’ object. You should see that the individual elements become children of the ‘Tank’ parent.
28. Download tank textures from google and apply them by dragging from the assets folder onto the tank. In this tutorial, we’ve looked at the Unity interface, how to add and modify objects in the scene and created our first game asset.
