But what happens if your texture is not a power of two? A variable in programming is similar to a variable in algebra that holds a numerical value. You must log in or sign up to reply here. The first part determines the value of the x coordinate of the vector. Scripting should have no font effects whatsoever. To change the width and height of the viewing volume. When the switch is open.

Before pressing any of these keys. Although lighting is a subject usually delayed for more advanced topics in game development. Be careful though because any changes you make in the editor. You may also click and drag the central small cube to resize the object in all directions uniformly. These represent the x. When it is selected. Clicking and dragging any of these will change the scale of the object in the respective directions.

The only exceptions to this are script files because they are edited and saved externally to the editor. In W position mode. Step 7. The specifics of transformation are discussed later. Click and drag any of these circles to rotate the cube in the associated directions. Step 9. Step To move the object freely. Step 8. In R scale mode. Note that while you are moving. A light displaying as a little sun symbol will appear in the Scene and the cube in the Game will become brighter.

Clicking and dragging from any of the arrowheads will move the object along that axis.

Changes made in script files are independent of the play button. To add a light. In E rotate mode. Now because we are looking at the cube front on in the Game.

This is great if you want to test out an idea to see how the game will react. This can be very annoying if you've made large changes not realizing you are in play mode as they will be wiped away as soon as you press stop. You will also notice that values in the Transform part of the Inspector change too.

The color of a GameObject comes from an associated material. New material will appear in the Project window and. To create a material. Move and scale the cube so that you can see it clearly in the Game window. The Art of Programming Mechanics scaling the cube that it changes in the Game window accordingly.

To add material to the cube. To change the name of the material. You'll notice that if you select the cube. To change the color of this material. Type in a new name and hit the Enter key.

Change this. Ensure that you have the correct spelling and capitalization. Whatever code you place inside Update will be run once each main loop. The large sphere view of the material in the Inspector will change to your chosen color. Note When you create a new JavaScript file. For large spaces. Select the color you want from the Color Popup and then close it. Rotate Vector3. This will place you in editing mode for the material name. Return to Unity and drag and drop the spin code from the Project window onto the cube in the Hierarchy window.

In the code editor type: Note The code in Step 15 contains the Unity function Update. The JavaScript created will be called NewbehaviorScript.

The cube will be colored. In the Project window. Unity will do this for you automatically. When you are done. Do not add. Both will achieve the same effect.

Wait a moment and then click on it again slowly. Holistic Game Development with Unity Step Map View. Press the play button and watch as the cube spins. Scripting languages have all the properties of programming languages.

The major difference between programming and scripting is that programming languages are compiled built into a program by the computer and then run afterward and a scripting language is Single scenes can also be imported from one project to another.

Help Screen. Scenes are saved inside projects. To save the application. Each project you create can have multiple scenes. In the dialog that pops up. Several fundamental constructs in programming are required to fully understand a programming language. When the switch is closed.

These are variables. It is a normal part of the learning process. In simplistic terms. Compilation checks through the code for errors and then builds it into a program. The fact that electricity has two states. Holistic Game Development with Unity interpreted by another program as it runs.

This is exactly how computer circuitry works. Some of the error messages will also seem quite vague and ambiguous for what they are trying to tell you. When the switch is open. It also provides a very powerful and yet simple way to develop game mechanics in Unity and many other game-editing environments.

Imagine a basic circuit illustrated as a battery. JavaScript is used in this book as the primary means of programming. Don't worry if you get lots of errors when you start programming. This book refers to the JavaScript you are about to learn as being compiled.

Although it is strictly a scripting language. When a program is compiled. Using this terminology. The AND gate takes two input currents. These gates are called AND. In computer science. If only one or none of the input currents is on. The Art of Programming Mechanics switches called logic gates allow for the circuit to be opened or closed.

In all. OR are called Boolean functions. If you are just learning about programming for the first time right now.

It will become much clearer as you begin to write your own programs. They work in the same way as the AND function does. It is common practice to place comments at the top of each program file to give an overview of the entire code. They are. Some examples are shown in Listing 1. The first is a way to block out an entire paragraph. You can write anything you want between these characters and it will be totally ignored by the compiler.

The author's advice is to use comments as frequently as possible. Another programmer may also insert comments if he makes a change. They are very useful when you write some ground-breaking code.

They allow you to insert explanations about your code or little reminders to what your code does. Holistic Game Development with Unity 1. I used the code I found in the Script Reference after doing a search for the word Rotate. The second type is a one liner. Will rotate any game object around the y axis Author: Penny de Byl Date: This function takes input and prints it to the screen.

JavaScript has numerous standard functions but also takes on added ones depending on the context. To define your own function in JavaScript. The most common newbie function taught is print or a derivative thereof. The Art of Programming Mechanics Use comments wisely and as you see fit. You put vegetables in. Programmers can also write their own functions. While functions are a programming element usually introduced to new programmers further down the track.

It contains prewritten code that can be reused over and over again. Functions available to you as a programmer will depend on the programming language.

It is quite legitimate to write an entire program without comments. Whenever the author thinks of functions. As Unity is running your game. In the line of code. A more suitable place to make an object red would be in the Start function. This function runs just once during the lifetime of the game object. It does not run over and over again like the Update function and therefore is a good place to put code that does not need to run for the life of the game object.

The value of y in this case would be Think of it as a storage box that you can put things into. Once the object is red. Another useful function is Start. These are the ones you can use in your JavaScript. If you are interested in other available functions. You can use it to set initial states and values for a game object. A variable in programming is similar to a variable in algebra that holds a numerical value.

Think of it as an initialization method for a game object. It is set to red just once. If there are five game objects each with Update functions in their scripts.

The different types of variables have different sized boxes. The integer size box is even bigger. If you don't know what value should be placed into a variable you do not need to assign one. These include integers whole numbers. Boolean values e. Variables don't just exist automatically in computer memory. The process of declaring a variable gives it a name. Listing Variables in computer memory can be conceptualized as boxes in a large storage space.

The smallest box is a Boolean. A character is the next size up. They must be declared. Some examples are shown in Listing The exact size of the boxes will change depending on operating system and computer processor. The Art of Programming Mechanics The differing types of information that can be stored in variables are called data types. It would hold all the alphanumeric characters such as those appearing on the keys of your keyboard and a couple of miscellaneous others.

Holistic Game Development with Unity 10 5. Variables can be named anything you like. A single character is enclosed in single quotes and a string in double quotes. You will notice the use of capital letters in some of the variable names shown beforehand.

One thing to note from Listing The reason being that if they were not. This is just one convention of using several words in the This brings us to another matter about naming variables.

You can add many JavaScript files into the same Unity application. This is a totally personal preference and makes no difference to the compiler. Consider the script in Listing 1.

We will examine other types of variables in later sections. The keyword private forces the variable to remain hidden for use inside the JavaScript file in which it is declared. The capital makes the variable name more readable as single words are easier to read. It cannot be seen for use by other code files. When a variable becomes exposed. Although they could be placed in a variety of locations.

In this example. For more information about naming conventions. In this case. Because conventions can vary slightly between languages. The Art of Programming Mechanics one name. Note that the objScaleX variable has the keyword private at the beginning of the declaration. You'll notice that there are no variables visible.

Step 1. In the Project. Step 3. Remember to press stop when finished. The starting file is supplied on the Web site for download. Highlight Cube in the Hierarchy and look at the resize script in the Inspector at the very bottom. Press play to watch the x scale of the cube change. The objScaleX variable is private and therefore not visible in the Inspector when the cube is selected.

Attached to the cube is the script from Listing 1. Step 4. Unity Hands On JavaScript Variables In this hands-on session you will create variables of your own to modify the scale of a cube and explore the differences between private and exposed variables. In the Scene you will see a white cube. Double-click on resize. Remove the private keyword and save the file. Any value you type into the Inspector for a variable will override what you have initialized the variable within the script.

Note that the value of objScaleX has been synchronized with the code in the script file. Save the script and switch back to Unity. Unity has made it look like three separate words in the Inspector. If this occurs it is most likely because the variable is exposed and has a value set in the Inspector. The Inspector value of 0. In the Inspector. Note Remember that variable names cannot have spaces. Change the value to 0.

You will notice that the variable has become exposed. If you keep it open and just click on the Unity window to switch back it becomes quicker to edit and re-edit script files.

You only need to click back and forth between the Unity and script editor windows to move between programs. Don't forget the semicolon after the value. Change the value of objScaleX to 2. This will put the variable into editing mode. The Inspector will still have 0. Note When a variable's value is changed in the Inspector.

Your variable is still called objScaleX in the script. Just remember to save the script file before switching back to Unity. Playing at this point will give the same results as before. The cube will now become very narrow. This can quickly become confusing when you start changing variable values in the script and expect them to affect the game when nothing seems to happen. Opening the resize.

This is only for readability purposes. Unity will automatically reload any script changes you have made. Switch back to the script editor. To update the Inspector values to those in the script file. Play the application to see the cube resized to double its width. If you have closed this window. Take a look at where the value of objScaleX is being used. If at some stage you need to access the value of a variable from another JavaScript file.

The author's advice is to keep the variable private until absolutely necessary—that way you can mess around with setting its values in the code file and you don't need to keep resetting the script in the Inspector.

If you only require the value in the variable inside a single script file. It is changing the X value of the Scale in the Transform component of the GameObject the script is attached to. The full listing of the new code is shown in Listing 1. Note When you start programming it is extremely common to make typing errors and to leave out parts of code such as semicolons on the end of lines or missing brackets.

Scripting should have no font effects whatsoever. It shows up in red at the very bottom of the Unity window. Make use of this coloration and bolding to check that you have keywords spelled correctly.

From there you can fix it. Note Do not use bold in your own code. Modifications are shown in bold. If you get an error.

Game unity with holistic pdf development

Save the script. In the script. Any coloration or bolding put in by the editor is for your own readability. If you make a mistake. The Art of Programming Mechanics Step Unity will detect it and give an error message.

It is put in automatically. Change the values of these scales in the Inspector to experiment with the shape of the cube as the differing scales are changed. The assignment operator you may be more familiar with as an equal sign and the multiplication and division operators are a little different to those used in traditional math. To use values already stored in a variable you simply refer to them in the equations using their name. More complex equations can also be created.

It is exactly the same as high school algebra. Relational Operators Unlike arithmetic operators that can calculate a plethora of values. First-time programmers often get these mixed up but with practice the differences become clear. Attached to the sphere is the script called grow. Note that there is already a variable added called growthRate.

The Update function continues to run over and over again while the application is playing. One equal sign means assign or place a value into a variable. In the Scene you will see a small white sphere. Modify the script to reflect the one in Listing 1. To the file add the code in Listing 1. Call it revolve. Now press play and watch as the x. This will continue until you stop playing.

Click on the Sphere in the Hierarchy. Note how the sphere grows slowly in size. Ensure that you can see the Scale part of the Transform component in the Inspector. For now. Double-click on grow. Functions will be explored in depth later. Unity Hands On Operators Step 1. Save the script and play in Unity. Unity also contains functions for all mathematical operations. Play the application. Note The parametric form for a circle is used in Listing 1. To access this information.

Sin Time. This new JavaScript file can be added to the Sphere while the grow script is still attached. The Sphere will resize slowly while moving in a circular motion. The value of Time.

Conditional statements can divert code to other parts of code or can make the same statement of code repeat over and over. These equations are based on modifying the x and y positions with cosine and sine functions and the time.

Select Sphere in the Hierarchy and check the Inspector to see that revolve is attached. Cos Time. Select revolve in the Project and drag and drop it onto the Sphere in the Hierarchy. In the Web site that opens. It is therefore a dynamic and constantly changing value. If it is not attached. They rely on Boolean algebra for making decisions on which way code should flow. Sin and Mathf. It is not expected at this early stage in learning Unity to know this type of information.

They need constructs around them to assess their value. The if-else statement was used in the logic circuit application mentioned earlier in the chapter. The simplest form of these is an if-else statement.

Holistic Game Development with Unity Conditional statements. Think of it as the type of logic you might use in deciding whether or not to wear a raincoat. Used quite a lot in simple artificial intelligence programming. We know it will stop moving when the conditional statement in Listing 1. If X were given a value of Open the fallandGrow. Update the fallandGrow. Save and play. Attached to the sphere is the script called fallandgrow. What is occurring is that the y position is constantly being reduced by 0.

Unity Hands On if-else Statements Step 1. We are now going to modify the code to make the sphere start to grow when it stops moving. As point y becomes greater than or equal to the groundLevel. Watch as the sphere moves down the screen until it stops.

The sphere will appear to fall as its y position is changed constantly by the script. Holistic Game Development with Unity Listing 1. There are several types of loop constructs. A loop is a segment of code that runs over and over again until an ending condition is met. The other programming construct that handles condition statements is a loop. Consider the code in Listing 1. The basic format of a for loop is shown in Listing 1. If the test comes back true.

After the contents of the parentheses are finished. A for loop to perform the same action as Listing 1. Enter the for loop. The second part performs a Boolean test on the value of the variable. You can also write i-- which will take one away from the variable i. This continues until the test becomes false and the loop quits.

The for loop reduces such repetitive tasks down into a few simple lines. The Art of Programming Mechanics The output from this code would be as the variable i starts with a value of 1. It would be a lot of code. Imagine printing out all the numbers between 1 and Attached to the Main Camera is the script called stackedSpheres. CreatePrimitive PrimitiveType.

Save the script and replay the application. Each sphere is created individually and its y position is changed by 1 with each new sphere. The Scene will appear empty. The stack of spheres will be replaced with a stack of cubes.

Placed the order already, hope it arrive in good condition. Nov 20, Posts: I purchased the Kindle mobi, I think version of this book from Amazon for reading on my iPad. While I have not been reading it cover to cover, what I have read, particularly the chapters on game rules and environmental mechanics, are fantastic. I can't heap enough praise on this book.

DAEvo , Dec 9, Feb 20, Posts: Nov 25, Posts: I chucked it my moneys worth and got a copy on kindle. Seems to right on the money although as with any book the stuff I already know I don't want to read but I don't want to skip just in case I miss some detail.
