guys really, plz help :)

I can now bitblt, cept I am new to arrays and keyboard input. First of all, I REALY need to know how to use key input to do things efficiently, all of VBs defualt things SUCK. Isnt there a getsynckey api? Also, if I make a type for tiles, how would I assign each tile a value then be able to retrieve that value?
the type looks like this:

Code:

---

Type tiles as integer
  x as integer
  y as integer
  tv as integer 'tile value..like lava, etc.
end type

---

how would I assign each tile a value and then recall it?

Code:

---

dim tile(maxtilesvar) as integer

---

I want it to basically say if it is the tile(0) then assign or view its tv, x, and y.
Also where is a good place to learn about text saving? DON'T FORGET HELP WITH KEY input is desired! THANKS GUYS

About the keys:
To test which keys has been pressed, use the KeyDown event of your main form.
If you want to know more about it, just create a new VB project with an empty form. In the form's code you place:

VB Code:

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
 
  Debug.Print "KeyCode: " & KeyCode & ", Shift: " & Shift
 
End Sub

In the immediate window, you'll see which keys has been pressed and which shift mask it has (shift = 1, ctrl = 2, alt = 4).
Look at the KeyCodeConstants and ShiftConstants in the object browser (press F2 in the VB IDE to access it).

About the tiles:
I would suggest you to name the user defined type 'tile', since one variable will hold information of only one tile. There's no need to store the X and Y in the tile, since it can be retrieved by the array index. If you are only interested in the type of a tile (the tv value), there's no need to use a user defined type, but this way you can store other information as well, like resistance. (It's a lot harder to move around in a swamp than on grass plains, for example.)

Dimension the tile array like this:

Code:

---

Dim Tiles(tileCountX - 1, tileCountY - 1) As Tile

---

Important note: Normally, the lowest index of an array is 0, so if you want an array of n elements, you should give it the dimension n-1 ! I admit this behaviour is indesirable, but you have to live with it.

To fill the tiles, you can do something like this:

VB Code:

For x = 0 to tileCountX - 1
        For y = 0 to tileCountY - 1
            Tiles(x, y).tv = value   'The source can be anything: another array, a text file, etc...
        Next y
    Next x

You can retrieve the tile value the same way: value = Tiles(x, y).tv

Another tip: install a copy of MSDN on your machine, if you haven't done so yet.

Good luck!

It is certainly strange behavior. C++ arrays are defined with the number of elements, then run from 0 to numElements - 1.

What if you use
Option Base 1
?

I think this sets the array base to be 1

It does, but then you get used to using base one, and thats just strange =).
