Hi

I spent several hours yesterday trying to fix an error with one of my classes. I have a clas which handles all the resources of a game, and they are all declared as public. When a function of the same rseource class is called by another class, its meant to display the values of some of my variables. I did all the nessecary code, yet the function only picks up the default value of all the resources, which is 0, when it constantly changes throughout runtime. Does anyone have any suggestions?

Thanks

Would it be possible for you to post the code for the class in question and the function that should be getting the value of the resources?

Hi

Sure, here is the code. (Irrelivant parts have been removed.)

Public Class SenateTown
Inherits Form
Dim Resource As New Resource

Public Sub SenateTownClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Click

If Cursor.Position.X > SenateSquarePos.X And Cursor.Position.X < SenateSquarePos.X + 254 And Cursor.Position.Y > SenateSquarePos.Y And Cursor.Position.Y < SenateSquarePos.Y + 209 Then
Call Resource.OpenSMarket()
End If

End class

I assume that you're trying to find out what values were set after you called Resource.OpenMarket.

I don't know if VB allows this or not, but in most programming languages you can't have a Class (let's think of this as a blueprint) and an object(thing made from the blueprints) of the same name.

It might be better to do
Dim Resource1 As new Resource

Did you try accessing the any of the members of Resource after you called Resource.OpenMarket()?

A class is just a blueprint for making an object that you want to use, so if you want to know what is inside the new object you have to access using the object you made.

For example
Resource1.strSWeapon

If you mouse over this then you should get what was stored by Resource1; however if you mouse over any of the parts between

Public Class Resource
and
End Class

You're not going to get any useful information because that isn't the actual object. It's just the blueprint.

I found a fairly decent tutorial on the nets. It talks about making classes and using get and set to access them as well.

I hope that I was of some help.

Hi

Thankyou, I will try out your idea and look at the link.

The class SenateTown was meant to open resource.openmarket, which is a new form window showing market prices of the resource variables.

Good to hear!

Also the next time that you post code if you highlight the code that you're posting and click the CODE button, the site will format the code so that it's easy for others to read.
