Pixel is a really simple programming language for the mobile pixel 3 lamborghini background. You might even say it’s stupid easy. That’s why this tutorial is only ten minutes long.
In this post, we’ll be teaching you everything you need to know about the Pixel programming language in just ten minutes. You might wonder why an entire blog post on a programming language can be condensed into just ten minutes of reading – well, because it’s so simple! In fact, some people may go so far as to call it ‘stupid easy’.
1. Learn the basics of Pixel
Pixel doesn’t require any huge setup – it’s simple to get started with. All you need to know before you can begin programming in Pixel is:
• A simple variable name is letters, numbers, and underscores. The first character must be a letter or an underscore.
If you want to write a variable named my_variable , for example, your code would look like this: var _my_variable = 5; . This is pretty similar to how other programming languages work, really.
2. Start creating variables with ‘var’
You can use the special variable var to create variables in your program: var my_variable = 5; . The ‘var’ keyword tells the compiler that you want to create a variable.
However, this won’t actually do anything useful (yet) – we need to actually assign a value to it.
3. Assign values to your variables
You can assign values to variables with the assignment operator: = . So if you want to assign the value of 5 to a variable named my_variable , you’d write var _my_variable = 5; . You could also write var _my_variable = var myvar = 5; , if you wanted. In general, it’s best to put each line on its own line in your code – it helps keep things organized and makes them easier to read!
4. Store data in arrays
You can store multiple values in a single variable by putting them inside of an array. You create an array by listing the values you want to include inside the array, separated by commas. For example: var _arr = [1, 2, 3]; .
Now _arr contains three values – 1, 2 and 3.
5. Store data in objects
But what if you want to store more than just numbers? Well, then you’d use objects! Objects are like arrays, except they can store strings as well as numbers. Objects look a lot like arrays – but instead of using commas ( , ) to separate their values, they use colons ( : ).
Note that you don’t need commas inside of strings ( ” , ” ) – they are already separated by whitespace!
For example, here’s how to create an object: var _obj = { fruit : ” grapes “, color : ” green “, }; .
Accessing values is simple – just use the dot operator. For example, if you wanted to access the color of the object in your program, you’d write _obj.color ; . You can also add new values to objects with the variable assignment operator: _obj.food = ‘grapes’; .
6. Check if something is true or false
You can check whether a value is true or false with an if statement. The general format for an if statement looks like this: if ( some_thing ) { some_thing } .
After the if statement, you can specify things. In the above example, you’d write if ( _obj.color == “green” ) { _obj.color = “yellow”; } . This would set the color of your object to yellow if its value is ‘green’.
7. Loop through a list of values
You can loop through a list of values with an ‘for’ statement – which looks like this: for ( var i = 0; i < [list_of_values]; i++ ) { … } . The ‘var’ in this code tells the compiler that you want to create a variable.
In this example, the loop would check to see if the value of i is equal to 0 – which you would write as var i = 0; . If so, it will increase by 1. If it’s not equal to zero, then it will continue checking and incrementing until it reaches the end of the list (i.e., until i equals [list_of_values] ). This also means that you could add more stuff after your variable declaration (since you don’t have to declare it again each time).
8. Move through a list of values
You can also use an ‘for’ statement to move through a list of values. Instead of incrementing the value of i each time, you could change it whenever you want. Here’s an example: for ( var i = 0; i < [list_of_values]; i++ ) { _obj.color = “blue”; } . This would set the color of your object to blue whenever you reach the end of the list – that’s what this line is doing: _obj.color = “blue”; . You can also use a second for loop here: for ( var i = 0; i < [list_of_values]; i++ ) { _obj.
