The using statement allows you to wrap sections of code that require connections to be closed toīe handled automatically when the block finishes. Rather, it uses the delegate field _runnable to implement theĭelegates give you a convenient way to favor composition over inheritance. Note that the class MyRunnable does not declare a run() method, as A delegate, exposed as the Impl property One interesting additional feature of Gosu is the ability to delegate the implementation of an interface to aĬlass variable using the delegate and represents keywords: Gosu classes can extend other classes and implement interfaces just like in Java, using theĮxtends and implements keywords respectively. SomeMethod( :enableLogging = true, :debug = false, SomeMethod(true, false, null, false, true) //bwah? Named arguments can be used to clarify code, so you don't end up with things like this: The for loop in Gosu allows you to iterate over both arrays and anything that implements Gosu supports the standard loop variants: for, while, do.

Var guess : String = null // Must declare the type because it can't be inferred Gosu is statically typed, but uses type inference to eliminate the vast majority of syntax overhead usually The Basics Variables and Type Declarations Check the README file for instructions or view the source.įor the truly impatient, you can evaluate some simple gosu expressions online over on the Play page.

It is noteworthy that Maven and Gradle projects do not require a local Gosu installation - the respective dependency resolution strategies will download the appropriate Gosu JARs from Maven Central.and MoreĪlternatively, a downloadable archive of simple command-line examples is available here. Run gradlew test to execute the JUnit tests contained within.

Gosu also plays nicely with Gradle - here is another simple starter project. Run mvn test to execute the JUnit tests contained within. If Maven is your thing, here is a simple starter project. If you installed the old 3.X plugin, delete the plugin and remove the Gosu SDK (File > Project Structure > SDKs), the new plugin does not need it. The plugin is hosted on the IntelliJ IDEA Plugin Repository and you can download it directly from within If this is the case and you want to experiment with new features, use the Gosu Lab IDE instead (see instructions above). Keep in mind, however, the latest new language features may not yet be supported in the IntelliJ plugin. The Gosu Plugin for IntelliJ is the recommended way to use Gosu. Just select Life from the Examples pane and run the game by pressing F5. You can try the bundled example projects like the Life game.

Now you’re equipped with the knowledge you need to use the =+ operator like a professional Python developer!Īre you interested in learning more about the Python programming language? Check out our complete How to Learn Python guide with top learning resources and online courses.There are several options to get started with Gosu depending on your needs Gosu Lab This tutorial discussed, with reference to an example, the basics of Python operators and how to use the += assignment operator. This operator is called the addition assignment operator. The += operator is an example of a Python assignment operator. The Python += operator performs an addition operator and then assigns the result of the operation to a variable. To learn more about how mathematical operators work in Python, read our beginner’s guide to Python math operators. Here are a few of the main assignment operators offered by Python: Operator You can also get membership operators, comparison operators, and identify operators in Python.Īssignment operators let you perform a mathematical function, then assign the resultant value to a variable. The Python programming language offers a range of other assignment operators. » MORE: Python Array: A Step-By-Step Guide Other Python Assignment Operators
