Type cast int to string

TileNumbers are stored in an array (TileNumber[0. 0] = 1), And are used To Print the map.
To avoid using a lengthy Select Case statement, I am trying To convert the integer value
from the TileNumber array To a String And use String concantenation To draw the image To
the screen as follows. I am getting the error message "Unable to convert from 'String' to
'TImage'"


Images are loaded as follows
Local Tile1 = LoadImage("Incbin::grassTile.bmp")
Local Tile2 = LoadImage("Incbin::rockTile.bmp")
Local Tile3 = LoadImage("Incbin::sandTile.bmp")


The screen is printed using the following loop.
For x = 0 To 24
For y = 0 To 17
Number = Int TileNumber[x, y]
TileString = String(Number)
DrawImage "Tile"+TileString, x*32, y*32
Next
Next

Tile1 is a variable name.

You can't do something like MyVar$ = "Tile" + "1"
and then
DrawImage MyVar

You can refer to a variable with the name, but you can't 'build up' a variable string that points to that variable.

Tile1 is a pointer to a location memory, while "Tile1" is a string variable, and points to a different memory location.

What you can, is something like:
- rename your tiles like tile1.png, tile2.png,...,tileN.png
- make a loop to load the tiles in an array of images:
for n = 1 to num_of_tiles
arr(n) = loadimage("tile" + n + ".png")
next

- then you can access to it from within a loop:
for n = 1 to num_of_tiles
drawimage arr(n),x,y
next

Hope it helps,

Either load the images into an array or put them into one large bitmap and use that as an animimage.

What they mean is:

Local Tile:TImage[3]
Tile[0] = LoadImage("Incbin::grassTile.bmp")
Tile[1] = LoadImage("Incbin::rockTile.bmp")
Tile[2] = LoadImage("Incbin::sandTile.bmp")

For x = 0 To 24
  For y = 0 To 17
    DrawImage Tile[TileNumber[x, y]], x*32, y*32
  Next
Next 

I think what they mean is string parsing into variable names, which is only possible in script languages.

If he really wanted he could use a hashtable, someone made one in blitzmax.
