Xaml game tutorial

Building and running should make the app work exactly as before. Add the Level class The Level class will contain the logic for the level. This class will need to be able to do things like trigger squares during the challenge phase of the Game and will need to also be able to contain logic like whether it is complete.

Set up your level with the following variables:. The following code shows how the solve method works:. Getting a nice baseline before diving deep into the code is usually a good idea.

Pretty pictures Project works, runs full screen, and loosely has some Metro magic going on. At this point I figured I would start getting the UI together. The game Simon has four squares that will represent a pattern. The pattern is generated and the user tries to replicate it. Easy enough, time to mockup! As soon as someone says, four squares, I think Windows logo, so I chose the Windows colors and came up with a simple game mockup that I used for designing.

Why yes, yes that mockup was created in MSPaint. Fortunately, squares are easy in XAML. So this is a little meatier section of code. On each iteration, we use the nextX and nextY to control when to move to the next line when we reach the right border and when to stop when we reach the bottom AND the right border at the same time.

In this article, we have defined the XAML used to host all the game content, and we have "painted" a checkerboard pattern on the game area, by adding WPF Rectangle controls in black and white to it. The next step will be to start adding the actual snake, as well as the food it will be eating. WPF Tutorial. Chapter introduction: In this article series, we're building a complete Snake game from scratch. Previous Next. At runtime, code in the particular platform project calls a LoadApplication method, passing to it a new instance of the App class in the.

NET Standard library. The App class constructor instantiates MainPage. LoadFromXaml initializes all the objects defined in the XAML file, connects them all together in parent-child relationships, attaches event handlers defined in code to events set in the XAML file, and sets the resultant tree of objects as the content of the page. When you compile and run this program, the Label element appears in the center of the page as the XAML suggests:.

Give the page a name, for example, HelloXamlPage :. Two files are added to the project, HelloXamlPage. Edit the HelloXamlPage.

Content :. The ContentPage. Content tags are part of the unique syntax of XAML. At first, they might appear to be invalid XML, but they are legal. The period is not a special character in XML. Content tags are called property element tags. Content is a property of ContentPage , and is generally set to a single view or a layout with child views. Normally properties become attributes in XAML, but it would be hard to set a Content attribute to a complex object.

For that reason, the property is expressed as an XML element consisting of the class name and the property name separated by a period. Now the Content property can be set between the ContentPage. Content tags, like this:. Many shortcuts exist to set the values of these properties. Some properties are basic data types: For example, the Title and Text properties are of type String , Rotation is of type Double , and IsVisible which is true by default and is set here only for illustration is of type Boolean.

For a property of any enumeration type, all you need to supply is a member name. For properties of more complex types, however, converters are used for parsing the XAML. These are classes in Xamarin. Forms that derive from TypeConverter. Many are public classes but some are not. For this particular XAML file, several of these classes play a role behind the scenes:. The ThicknessTypeConverter can handle one, two, or four numbers separated by commas.

If one number is supplied, it applies to all four sides. With two numbers, the first is left and right padding, and the second is top and bottom. Four numbers are in the order left, top, right, and bottom. The LayoutOptionsConverter can convert the names of public static fields of the LayoutOptions structure to values of type LayoutOptions.
