Creating a class and accessing new objects within the class

I have create a somewhat simple class, in a seperate class file from my main form and program class called InGameObject.

class InGameObject
{

string name;
int xCord, yCord;

public InGameObject(string Name, int XCord, int YCord){
name = Name;
xCord = XCord;
yCord = YCord;
}

public InGameObject() {
InGameObject HomeButton = new InGameObject();
HomeButton.name = "HomeButton";
HomeButton.xCord = 30;
HomeButton.yCord = 200;
}

private void GotoObjectLocation(int x, int y){
}
}

However, I can't seem to access the net new object, HomeButon, outside of the class. i know I am missing something really simple in regards to the constructor.

Can you please assist.

Tks

You should define HomeButton as a public variable on the class level and set it a value in the constructor . You better name this variable buttonHome as capital letters are used for class names and not for methods or variables.

Hello, you meant this?

class InGameObject
    {

        string name;
        int xCord, yCord;

        public InGameObject(string Name, int XCord, int YCord){
            name = Name;
            xCord = XCord;
            yCord = YCord;
        }

       public InGameObject() {
        name = "HomeButton";
        xCord = 30;
        yCord = 200;        
        }
        
        private void GotoObjectLocation(int x, int y){       
        }
 }

Open in new window

Then outside your class, example in your form:

public MyForm()
{
       InGameObject HomeButton = new InGameObject();
}

Open in new window

You are creating a local copy of the object within the object itself. Create the object externally. Ref: hongjun's post.

Will give it a try. Do I create the instance of the new object within the Main Method of the application? I have a lot of new objects to create for that class so looking for the best option.

Thanks

My comment on https://www.experts-exchange.com/questions/27398561/Creating-a-class-and-accessing-new-objects-within-the-class.html#36973923 will be good enough.

//Default constructor
InGameObject oDefault = new InGameObject();
Console.WriteLine(oDefault.Name);

//Overloaded constructor
InGameObject oOverloaded1 = new InGameObject("myname1", 1, 1);
Console.WriteLine(oOverloaded1.Name);

//Overloaded constructor
InGameObject oOverloaded2 = new InGameObject("myname2", 1, 1);
Console.WriteLine(oOverloaded2.Name);

Open in new window
