Making Sprite Class And Cycling Through Image Arrays
Feb 2, 2012
I am using vb.net by the way. From what I understand, Xna is not usable in visual Basic. Therefore, in order to create my characters, I defined a sprite class. Now my question is.... (I am drawing everything using a timer on the form btw by the process of invalidation.)... how do I use time to cycle through the images in an image array while the instance has no focus, and whilst the class inherits the "Control" class? Basically, how do i get these instances to act without user input? I want a character to eventually respond to user input, but I also need npcs that do not need any input in order to move themselves. Also, I need this in such a way that each instance's processes do NOT interfere with the processes of others. So that whatever timing I use does not also stall the whole window/form.

I am currently making a small flood runner like game, I completed most of it, but I can't seem to get the jump action right. I got it to jump straight up and back down again, but it doesn't work when I use a left/right arrow key with it to perform a left/right jump. The sprite goes straight up if I only press space.What I want- The sprites goes up and right or left when I press space while holding right or left.

I can't seem to find a way to get the Transparency of the character sprite to work. It always seems to take the background image of the form no matter how I tweak it.

not to use ArrayList for making my arrays in VB.NET. I would like to hear opinions about that, why shouldn't I? What is the best method for creating and manipulating array contents, dimensions etc?

Below you will find a code sample that I have dummied up to try and demonstrate the issue I am having. However, this is just a dummied up piece of code. The actual program has noting to do with STUDENTS or TEACHERS. Basically, the problem I'm having is trying to have a CLASS within another CLASS each of which contain ARRAYS that need to be dynamic in size. The sample has a CLASS called STUDENTS that can have in theory many students, the number of which are unknown to the CLASS. I need to be able to add STUDENTS to the ARRAY programmatically.
The CLASSROOM Class should also be an Array since each TEACHER will have MANY Students. There will be only 1 Teacher for a given classroom but the SCHOOL will have MANY CLASSROOMS. Again, I need to programmatically add Teachers and Students without having predefined Array sizes. The code I have listed below will NOT work but it demonstrates what I am trying to achieve. I want to be able to reference the CLASS by using something like this ...
School(iTeacherIndex).Student(iStudentIndex) = "Rick Smith"
I feel like I should be able to use ARRAYLIST in both classes but haven't been able to get it to work. I've tried DIM'ing as ARRAY and can't get that to work either.If I can get ARRAYLIST to work then I shouldn't need to worry about expanding the array via UBOUND (if it's even possible).The REAL question is "How do I have a CLASS within a CLASS, each of which has ARRAYS that need to be dynamic in nature so they can be expanded as needed? The size of the array cannot be determined ahead of time".
REMEMBER . . . the actual program has nothing to do with Students and Teachers. This was just my way of demonstrating the issue using an analogy that I thought everyone could understand. The actual Class is much more involved.I have purposely hardcoded some values just to make the sample easier to work with. This is NOT how I normally program but is just here to hopefully make things a little more clear.
Here is the sample code . . .
'***********************************************************************************
'***********************************************************************************
'***********************************************************************************
'Here is the code that is in the form - This obviously doesn't work
Private Sub TeacherTestDemo()
Dim iTeacherIndex As Byte
Dim iStudentIndex As Byte

I am making a array (unknown value) into a grid for a game of pairs (where you must get both of the cards). So far I have specified the array to a specific size of either 6, 6 10,10 or 16, 16. using a button. The selection is defined from the button as specified before
Dim NumberOfCards(Selection) As Integer
Dim NumberOfCards(Selection) As Integer
Now I have a panel box which I want to add the number of rows / columns as the array sizes which I cannot do. But also add a image specific to all of them.

I'm making a custom class that mocks the System.Drawing.Rectangle class because the Rectangle class doesn't have a name property. I need a name property because I am adding all of my rectangles to a collection and I need a little more info stored than just their locale and size. So I changed the _onPaint event but nothing is working out when I run the program?
Public Class Rectanglar : Inherits UserControl
Public BackgroundColor As Color = Color.Blue

This section of code is part of a much larger program.However, I can't seem to find the problem with this error.Error: Object reference not set to an instance of an object.[code]I'm using this array inside of a class form to maintain the memory of a computer player in a rock, paper, scissors game. There are two computer players involved; thus, the need for a unique instance of each array for each player.I'm struggling with this program and all of my errors are gone until I try to run the main form.I can link more code if needed.

Is it possible for one class to access an array of values within another class as a readonly property of the second class? All of the examples and references on class properties imply that one can only retrieve one value by calling a class' property.

EDIT: SI have a web service which uses a class of functions in order to return data used in various business processes (via InfoPath). One of the functions takes a given SQLCommand object and executes it into a SQLDataReader. Now depending on the SQL command text used this may return one or many rows of one or many columns. So what is the best class for this function to return bearing in mind it needs to be serialized by the web service.
My existing code is:
Dim array As New ArrayList

I have 2 arrays. One is an array of images other an array of numbers. The images are card faces, (Card(i)), the integers are the corresponding values of the cards (Value(i)). I want to associate the card face with a corresponding value. However, everytime I do what I think is correct, I get an error stating that I cant convert an image to an integer and visa versa.

I am trying to use several Class arrays to hold values that I will cycle through at a later point to perform some calculations. I need to change the array sizes to fit the data as it is entered. I am using one procedure to set the first element of each array and then a separate procedure to pass the additional values as they are entered.
Until my last attempt at changing my code, my StartBalance sub seemed to work, I could step through and see the values assigned to the class arrays in the code block. However, when it moved on to the Transaction sub, it did not recognize that the first set of values were set, the array shows zero values for index 1.
I have gone through several changes trying different ideas from reading blogs and articles, but I guess I am not understanding how these work. I even used the class arrays directly instead of the Property procedures to see if I would get a different result, but I do not.
I believe I must be approaching this incorrectly and though I can find dozens of examples of setting class variables and even a couple on using arrays as class variable, I can not find any that show how to then pass values to those arrays.
Public Class Statement
Private _tranDate(1) As Date
Private _amount(1) As Double

I have an app that loads a jpg into a picyure box, then updates exif data in exifworks classThe problem is that when I save the image(from image used for picture box) or class (to save exif data) then try to delete, sometimes I get success, others it won't allow delet I have gone to the trouble of using gc.collect, do events, put the delete in a timer & wait for the delete before continuing & still get the problem

I was wondering if it was possible to make an array of a class. I made a class called creatures (for a game of course) and wanted to make an array of that class. So I tried "public creature() as new creatures", and it had a problem with using an array with new. Is there a way around this. All I am using the class for is variables. i.e.: in my class all i have is dim health, defense

I'm making a blackjack game for class. It's been better programming in VB than it has in C#, but I don't know how to link button subs (BTN_Deal_Click or BTN_Deal; I can't decide which one will work) to one another. For example, after the code in BTN_Deal has been run, the program is supposed to wait for the user to click either the Hit or the Stand button.

I haven't quote grasped this whole "class" concept yet, but I'm working on it. When following the instructions below, the "test" portion of this code: "test.variable". It has an underlined error that says that "test" is not declared. If I remove the "test" word then the ".variable" shows not declared. I'm using Visual Studios 8 if that makes any difference. I have a pre-existing variable in a project that I would like to monitor for changes.
Re: Detect variable change.
Make your variable a class with an event.
Make your class:
VB.NET Syntax (Toggle Plain Text)
Public Class myVar
Private mValue As Integer
Public Event VariableChanged(ByVal mvalue As Integer)

I Use the following code to detect if a sprite should be going up or down and the response
If (pos.Y + 100) >= Sprite.BottomY Then
Going_up = True
pos.Y = Sprite.BottomY - 130
End If
[Code]...
but it's pretty terrible. It only works when the sprite starts at the top, and when I want to change the BottomY and TopY, it just starts glitching. What is a better to detect if the sprite should be going up or down?
