Variables and Functions
Variables
Boxes that contain information. you need a different variable for each piece of information
Debug.log format
Debug.log() a variable goes inside the set of parentheses. example: Debug.log(uhr)
What is Void start
an example of function that doesn't return anything. its type is void
where do the "inner workings" of a function begin
between { and }
how do we start our variable definiton
by saying what type of box we'd like
variable formula
declaration = Initialisation
what do variables and parameters go in
parentheses
int
integer, or a whole number.
what happens to a variable given a value
it will keep the value until you give it a new one. Example: Using Unity Engine; Using System.Collections; public class: VariablesandFunctions : MonoBehaviour { Int uhr = 5; Void Start (){ Debug.log(uhr * 5); } } this line of code will multiply uhr by 5, and the console will read the value as 25 (5*5)
Name of the variable
just a name to reference it by. can literally be anything, but it can't start with a number or symbol
return
literally returns whatever goes after it. ex: Int thing(int num)
what does a function do
take the boxes that we have storing information and give us boxes back, or 'return' as it is known
what do the curly braces open and close around
the actions that are in our function
what goes inside the parentheses of a function
the data that is sent to parameters
declaration
the first part of the variable; consists of the type (In blue), and the name of the variable (case sensitive)
initialisation
the second part of the variable, where information is stored. also called the value
type
the type of variable. Ex: Integer Int
function format
type FunctionName(type parameter names);
start function format
void Start { }
what can we do with making our own functions
we can give it a specific type of box to return
what can we do with Debug.log
we can output anything to the console (including variables)
what happens when you make a new script
we're given start and update functions
Value
what the variable equals. for example, Int uhr = 5. the variable would equal five
when is the function Start called
when an object the script is attached to enters a scene
how do we end any line of code
with a semi colon. Ex: Debug.log();
what happens when you log the value of the variable, save the script, and attach it to an object
you can see it in the console in unity, and you can also see the value when you hit the play button
