When we want to count the number of items in an iterable, that meet some condition, we can use comprehension to produce an idiomatic syntax: # Count the numbers in `range(1000)` that are even and contain the digit `9`: print (sum( 1 for x in range(1000) if x % 2 == 0 and '9' in str...

In Java, we can convert between integer values and floating-point values. Also, since every character corresponds to a number in the Unicode encoding, char types can be converted to and from the integer and floating-point types. boolean is the only primitive datatype that cannot be converted to or f...

Computed GOTO allows branching of the program according to the value of an integer expression. GOTO (label_1, label_2,... label_n) scalar-integer-expression If scalar-integer-expression is equal to 1 the program continues at statement label label_1, if it is equal to 2 it goes to label_2 and so ...

There are three MonoBehaviour methods that can be made coroutines. Start() OnBecameVisible() OnLevelWasLoaded() This can be used to create, for example, scripts that execute only when the object is visible to a camera. using UnityEngine; using System.Collections; public class RotateObje...

Usage If you have a long running operation that relies on the not-thread-safe Unity API, use Coroutines to split it over multiple frames and keep your application responsive. Coroutines also help performing expensive actions every nth frame instead of running that action each frame. Splitting Lon...

You create new ScriptableObject instances through ScriptableObject.CreateInstance<T>() T obj = ScriptableObject.CreateInstance<T>(); Where T extends ScriptableObject. Do not create ScriptableObjects by calling their constructors, ie. new ScriptableObject(). Creating ScriptableO...

Often you will get into a state where you have a partially typed command sequence in progress, but you want to abort it. You can abort it with either of the following keybindings: C-g EscEscEsc

If profiling your build shows significant time spend in Configuring Projects, the Configure on Demand option might improve your performance. You can enable Configure on Demand mode by editing $GRADLE_USER_HOME/.gradle/gradle.properties (~/.gradle/gradle.properties by default), and setting org.gradl...

VBA defines a number of string constants for special characters like: vbCr : Carriage-Return 'Same as "\r" in C style languages. vbLf : Line-Feed 'Same as "\n" in C style languages. vbCrLf : Carriage-Return & Line-Feed (a new-line in Windows) vbTab: Tab Character vbNul...

The scope of a variable in a block { ... }, begins after declaration and ends at the end of the block. If there is nested block, the inner block can hide the scope of a variable which is declared in the outer block. { int x = 100; // ^ // Scope of `x` begins here // } // ...

The border-collapse property applies only to tables (and elements displayed as display: table or inline-table) and sets whether the table borders are collapsed into a single border or detached as in standard HTML. table { border-collapse: separate; /* default */ border-spacing: 2px; /* Only w...

The default scope for a variable is the enclosing container. If outside a script, or other container then the scope is Global. To specify a scope, it is prefixed to the variable name $scope:varname like so: $foo = "Global Scope" function myFunc { $foo = "Function (local) scope&...

Giving this enumeration as Example: enum Compass { NORTH(0), EAST(90), SOUTH(180), WEST(270); private int degree; Compass(int deg){ degree = deg; } public int getDegree(){ return degree; } } In Java an enum class is like any other c...
