For value types, “==” and Equals() works same way : Compare two objects by VALUE
int i = 5;
int k= 5;
i == k > True
i.Equals(k) > True
For reference types, both works differently :
“==” compares REFERENCE – returns true if and only if both references point to the SAME object.
Equals method compares object by VALUE.
StringBuilder sb1 = new StringBuilder(”Mahesh”);
StringBuilder sb2 = new StringBuilder(”Mahesh”);
sb1 == sb2 > False
sb1.Equals(sb2) > True
String s1 = “zzz”;
String s2 = “zzz”;
In above case the results will be,
s1 == s2 > True
s1.Equals(s2) > True
Why? Does that mean String a Value Type?
No, String IS a Reference Type. Although string is a reference type, the equality operators (== and !=) are defined to compare the values of string objects, not references. This makes testing for string equality more intuitive. For example:
The starter kit comes as an MSI installable package. It adds a new template into Visual Studio, making it possible for you to choose File | New | Role Playing Game from the menu. This one step process initiates the creation of a new solution containing the source for a complete tile-based role playing game. In Figure 1 you can see the Solution Explorer and Class View for the created project. By viewing this screen shot you can get some sense of what is available inside the start kit. Obviously this is a fairly extensive bit of source code with lots of logic for you to digest and learn from, especially if you are new to game development.
Acquiring the Starting Kit
The downloads for the RGP Starter Kit are broken out into versions for XNA Game Studio 2.0 and 3.0. There is also a distinction between code that targets Windows and code for the XBox:
- For XNA Game Studio 3.0 Windows
- For XNA Game Studio 3.0 XBox 360
- For XNA Game Studio 2.0 Windows
- For XNA Game Studio 2.0 XBox 360
