Hi,

I'm trying to create a simple board using a bunch of small squares and got the error message:

Here is the code the error is complaining about:

function createBoard(width, height)
	for w = 0 to width
		for h = 0 to height
		CreateObjectBox(1, 1, 1)
		SetObjectPosition(1, 1*w, 1*h, 0)
		next h
	next w

EDIT:
Round 2

+ Code Snippet

function createBoard(width, height)
	for w = 0 to width
		for h = 0 to height
		CreateObjectBox(1+(w*h), 1, 1)
		SetObjectPosition(1+(w*h), 1*w, 1*h, 0)
		next h
	next w
endfunction

No luck!

When width = 6 and height =8 you will get exactly the same number as width = 8 and height = 6
I think you might want to use a sequential number as the object id
also createobjectbox() should be CreateObjectBox(1+(w*h), 1, 1, 1) // Requires three 1s because width, height, depth

lso createobjectbox() should be CreateObjectBox(1+(w*h), 1, 1, 1) // Requires three 1s because width, height, depth

Ok, thanks for the advice. I just started with AppGameKit and am hoping to win the e-books. It?s 1am here so I will try to fix it early in the morning. Is there a way to automatically allocate the id?

Is there a way to automatically allocate the id?

yes. see HERE.

so, you'd do something like:

+ Code Snippet

SetErrorMode(2)

// set window properties
SetWindowTitle( "boxes" )
SetWindowSize( 1280,720, 0 )

// set display properties
SetVirtualResolution( 1280,720)
SetOrientationAllowed( 1, 1, 1, 1 )
SetSyncRate( 30, 0 ) 
SetScissor( 0,0,0,0 )
UseNewDefaultFonts( 1 ) 

GLOBAL Map as Integer [4,4]
for x = 0 to 4
	for z = 0 to 4
		ThisBox = CreateObjectBox(1,Random(1,3),1)
		SetObjectPosition(ThisBox, x, 0, z)
		SetObjectColor(ThisBox,Random(128,255), Random(128,255), Random(128,255), 255)
		Map[x,z] = ThisBox
	next z
next x
	
do

    If GetRawKeyState(27) then Exit    

	if Last# + 0.1 &lt; Timer()
		SetObjectColor(Map[Random(0,4),Random(0,4)],Random(128,255), Random(128,255), Random(128,255), 255)
		Last# = Timer()
	Endif
	
    Print( ScreenFPS() )
    Sync()
loop

the idea is to let AppGameKit allocate the object IDs (my preference) but you'll need some way to reference those object IDs later.

so, if the boxes represent your map, make an array (ie, Map[4,4] ) for easy reference to those IDs.

if you want to change one of the boxes, say the box at 1,1 then the ID of that box would = Map[1,1]

this:

+ Code Snippet

	if Last# + 0.1 &lt; Timer()
		SetObjectColor(Map[Random(0,4),Random(0,4)],Random(128,255), Random(128,255), Random(128,255), 255)
		Last# = Timer()
	Endif

...finds the object id at a random location in the Map and changes its color, for example.

otherwise, do yourself a big favor and skim through the guides and the rest of the help files

+ Code Snippet

Global BOARD_SIZE as Integer

BOARD_SIZE = (BOARD_SIZE_WIDTH * BOARD_SIZE_HEIGHT)

Global boardpiece as BoardPiece[BOARD_SIZE]

error: Unexpected token "board_size", Array dimension must be an integer literal or a constant

When defining an array you can only use a literal or constant.
You can however do this;

+ Code Snippet

Global boardpiece as BoardPiece[]
boardpiece.length = BOARD_SIZE

Also I would recommend against making your type the same name as your variable. It tends to break the goto definition function within the IDE
