I get "Expression of type 'Int' cannot be indexed" when i run the following code that worked in b3d. This was nifty way to get a batch of images loaded in b3d

For i=1 To 20
NumberList[i] = LoadImage ("C:DungeonCrawlGameMap editorBmpNumbersNumber" + Str[i] + ".bmp")
Next

You need to declare the array first, and also, it must be of type TImage if you're loading Images into it.

Also, arrays are 0-based in Blitzmax (I can't remember about Blitz3D), so declaring an array with 20 elements, they will be numbered 0-19.

Strict

Global NumberList:TImage[20]

For Local i:Int = 0 To 19  ' variable 'i' will now be local to this For/Next loop only
NumberList[i] = LoadImage ("C:DungeonCrawlGameMap editorBmpNumbersNumber" + String(i) + ".bmp")
Next


Also, put "Strict" right at the top of your code. This forces you to declare all variables before using them - may seem like an inconvenience but it makes debugging a hell of a lot easier later.

Ok. I skipped posting the array declaration, but i shouldn't have since you ended up pointing out the TImage type issue that I wasn't aware of. Thanks for the tips and time to answer these questions and many more to come as I learn blitzmax.

hmm, still not working. I get an "Identifier 'Str' not found."

Global NumberList:TImage[20]

For i = 0 To 19
NumberList[i] = LoadImage ("C:DungeonCrawlGameMap editorBmpNumbersNumber" + Str[i] + ".bmp")
Next

Gfk was casting to an Int to a String, you copied his code wrong... although you don't need to cast:

NumberList[i] = LoadImage ("C:DungeonCrawlGameMap editorBmpNumbersNumber" + i + ".bmp")


Also that path looks wrong too... where are your images?

C:DungeonCrawlGameMap editorBmpNumbersNumber????

maybe it should be:
C:DungeonCrawlGameMapeditorBmpNumbersNumber
or something....

Oops. You are right. lol. The forward slash for the path were deleted when i posted. Not sure why.

And try putting the word SuperStrict at the top of your source. It will help you. Really! :-)
