Unity comes with a number of basic view tabs that can be laid out in various ways to the taste of the user. The big five are:. Meshes are the way 3D geometry is represented in Unity. Here are some awesome free tutorials. What good teaching material is there? Unity supports a variety of 3D formats, including. The basic tools for manipulating meshes are the scaling, rotation, and translation buttons in the upper left corner of the interface.
These buttons add control icons to the models in the editor view, which can then be used to manipulate them in space. To alter the texture or physics properties of an object, select them and use the inspector view to analyze the material and rigidbody elements. However, a more robust and realistic way to handle UI elements is to use the 3D text and Quad GameObjects with transparent textures and an unlit transparent shader to place HUD elements into the game world as entities.
In the hierarchy view, these gameplay elements can be dragged onto the main camera to make them children, ensuring that they move and rotate with the camera. GUI elements text and textures can have their size and scale adjusted using the relevant fields in the inspector tab. Read More , and can be dragged directly onto game objects from the project tab.
To import a texture, convert it to a. After a few seconds, a loading bar will appear in the editor. Lights are GameObjects which project radiance onto the world. If there are no lights in your scene, all polygons are drawn at the same brightness level, giving the world a flat, washed-out look. Lights can be positioned, rotated, and have several internal characteristics that you can customize. The intensity slider controls the brightness of the light, and the range controls how quickly it fades out. The guidelines in the scene view show you the maximum range of the illumination.
Play with both settings to achieve the desired effect. You can also adjust the color of the light, the pattern cookie displayed on the surface the light is pointed at, and what kind of flare appears onscreen when looking directly at the light. The cookie can be used to fake more realistic light patterns, create dramatic false shadows, and simulate projectors.

The three main kinds of light are spot , point , and directional. Spot lights have a location in 3D space and project light only in one direction in a cone of variable angle. These are good for flashlights, searchlights, and, in general, give you more precise control of lighting. Spot lights can cast shadows. Point lights have a location in 3D space, and cast light evenly in all directions.
Point lights do not cast shadows. Directional lights , finally, are used to simulate sunlight: they project light in a direction as though from infinitely far away. Directional lights affect every object in the scene, and can produce shadows.
A Particle system is a GameObject that generates and controls hundreds or thousands of particles simultaneously. Particles are small, optimized 2D objects displayed in 3D space. Particle systems use simplified rendering and physics, but can display thousands of entities in real time without stuttering, making them ideal for smoke, fire, rain, sparks, magic effects, and more.
You can change the size, speed, direction, rotation, color, and texture of each particle, and set most of those parameters to change over time as well. First, we need two paddles, and a ball. The whole game will need to be dramatically lit. That breaks down into a ball object a sphere , a spawner , two paddle props with particle emitters attached, a 3D-text entity , and a spot light. Scale it appropriately, duplicate it , and put a sphere between the paddles for the ball. Then, create a 3DText object and scale and position it correctly, changing the font size attribute to get a less pixelated image.
Next, create two particle systems , pick the characteristics you want, and attach them to the paddles. Before we finish, we need to create two additional cubes to be bumpers, to prevent the ball from bouncing out of the game area. We can make them invisible by unchecking the mesh renderer in the inspector tab.
If you hit play, you can now see the basic elements of our game laid out. Once you have a script attached to an object, you can revise it by double clicking on it in the inspector.
This opens MonoDevelop , the default development environment for Unity. In essence, Monodevelop is a text editor with features specifically optimized toward programming. Keywords and comments are highlighted in blue and green , and numerical values and strings appear in red. You can build your scripts from inside the editor, to check for syntax errors, like so:.
You can then call methods or set variables for each of these elements to enact the changes you want.

If you want a script on an object to affect the properties of a different object, you can create an empty GameObject variable in your script, and use the inspector to assign it to another object in the scene. A list of the elements an object might have is as follows taken from the inspector view of one of our paddles in the above example :. Each of these aspects of the object can be influenced from within a script.
The transform functions for a GameObject in Unity control the physical parameters of that object: its scale , its position , and its orientation. You can access them from within a script like this:. In the above examples, the named variables are of the types specified in the names. You can access the X , Y , and Z components of each for example, transform.
