Hey, so I defined some functions to create some custom types I've defined (2dVector and 2dButton). I've tested create2dVector() and it works out fine, but when I attempt to use create2dButton, the compiler crashes when I attempt to compile my program.

Main.dba

+ Code Snippet

#CONSTANT RGB_BLACK = RGB(0,0,0)
#CONSTANT RGB_WHITE = RGB(255,255,255)
#CONSTANT RGB_RED = RGB(255,0,0)
#CONSTANT RGB_GREEN = RGB(0,255,0)
#CONSTANT RGB_BLUE = RGB(0,0,255)


FLAG_Quit = 0
RESOLUTION_X = 800
RESOLUTION_Y = 600
RESOLUTION_DEPTH = 32

SYNC ON : SYNC RATE 30
SET Display Mode RESOLUTION_X,RESOLUTION_Y,RESOLUTION_DEPTH
SET TEXT TRANSPARENT

TYPE 2dVector
    X,Y
ENDTYPE

TYPE 2dButton
    position as 2dVector ,
    size as 2dVector ,
    caption$,
    buttonColor as DWORD ,
    textColor as DWORD
ENDTYPE

GOSUB MainMenu

MainMenu:
    REM quitButton as 2dButton = createButton(create2dVector(400,300),create2dVector(50,20),"Quit",RGB_BLUE,RGB_WHITE)
    WHILE FLAG_Quit <> 1
        CLS
        REM drawButton(quitButton)
        if inkey$()="q" then FLAG_Quit = 1
    ENDWHILE
RETURN

2D_Library.dba

+ Code Snippet

function create2dVector(posX,posY)
    newVector as 2dVector
    newVector.X = posX
    newVector.Y = posY
ENDFUNCTION newVector

Menu_Library.dba

+ Code Snippet

function createButton(Position as 2dVector ,Size as 2dVector ,Caption$, ButtonColor as DWORD , TextColor as DWORD )
    newButton as 2dButton
    newButton.position.X = Position.X - Size.X/2
    newButton.position.Y = Position.Y - Size.Y/2
    newButton.size = Size
    newButton.caption$ = Caption$
    newButton.buttonColor = ButtonColor
    newButton.textColor = TextColor
ENDFUNCTION newButton

function DrawButton( button as 2dButton )
    BOX button.position.X,button.position.Y,button.size.X,button.size.Y,button.buttonColor,button.buttonColor,button.buttonColor,button.buttonColor
    textX = button.position.X + button.size.X/2
    textY = button.position.Y + button.size.Y/2
    INK textColor,RGB_BLACK
    CENTER TEXT textX,textY,caption$
ENDFUNCTION

It could be due to the IDE combining the files in the wrong order, but as I don't have a compiler handy with me at the moment, and because you have neglected to post any indication of the error message you get, then all I can do is guess

Get the latest Matrix1Utility plug-ins (03-DEC-2010)

Well, I wasn't getting an error, just a crash report from Windows; however, I just restarted my computer to get a few updates and when I reopened my project it was working just fine.

I noticed that my code files have rearranged themselves in the compiler so I can only guess that what you said was correct. Something about the order was screwing with the compiler.

Thanks for your help

No wait, my mistake, I forgot to un-REM the line that's causing the crash.

This is the line that's causing the problem.

+ Code Snippet

quitButton as 2dButton = createButton(create2dVector(400,300),create2dVector(50,20),"Quit",RGB_BLUE,RGB_WHITE)

Here's the crash report, if it's of any help.

Try declaring the variable and assigning it a value on different lines?

I just tried that, no effect.
However, I separated the create2dVector functions and made them into variables of type 2dVector and I got the error "Both user defined type values must use the same type at line 39."

Here's my edited MainMenu subroutine.

+ Code Snippet

MainMenu:
    quitButton as 2dButton
    test1 as 2dVector
    test2 as 2dVector
    test1 = create2dVector(400,300)   'This is line 39
    test2 = create2dVector(50,20)
    quitButton = createButton(test1,test2,"Quit",RGB_BLUE,RGB_WHITE)
    WHILE FLAG_Quit <> 1
        CLS
        REM drawButton(quitButton)
        if inkey$()="q" then FLAG_Quit = 1
    ENDWHILE
RETURN

I've never seen this done before.

+ Code Snippet


TYPE 2dVector
    X,Y
ENDTYPE

Should it not be

+ Code Snippet

TYPE 2dVector
    X as integer
    Y as integer
ENDTYPE

>Edit<

Whether it should be like that or not I dunno, lol, but it doesn't seem to be causing your problem.

My other concern about your code is where you have...

+ Code Snippet

function create2dVector(posX,posY)
    newVector as 2dVector
    newVector.X = posX
    newVector.Y = posY
ENDFUNCTION newVector

I'm not sure you can declare a variable as a type and then pass it in a function like that.

Yeah, that wouldn't work. You can't pass UDT's out of functions, but you can in, so: create2dVector( newVector as 2dVector ).

For this you just make a global passing variable, for instance in my vector class and every other class:

+ Code Snippet

gosub declare_Math

position as vector3
setVector3(0,23,11) : position = _vector3

//end

// maths classes
type vector3
    x                   as float
    y                   as float
    z                   as float
endtype

declare_Math:
    global _vector3     as vector3
return

function setVector3( x as float, y as float, z as float )
    _vector3.x = x : _vector3.y = y : _vector3.z = z
endfunction

A dream is a fantasy, if you achieve that fantasy it was never a dream to begin with.
