Making a map!

[Achilles]

I'm planning on making a game that quizes the user on the capitals and positions of South American countries (eventually all the world once I get to summer...). However, In order to ask a question the computer will randomly highlight one of the countries by making the whole country a specific unique color. Instead of making about 15 different images where each different image has a different color highlighted I was wondering if there was a way to "fill" (like paint does) a certain country.

I have a short example:

GuiCreate('Map of South America', 516, 761) 
GuiCtrlCreatePic(@ScriptDir & '\South America Map.gif', 5, 5, 506, 751) ;Image is attached
GUISetState()

Do 
    Sleep(50) 
Until GuiGetMsg() = -3

I suggest you google for floodfill dll, or flood-fill dll.

Wont that should be in Example Script forum?

No, he is asking for help.

@Piano_man

I'm not aware of a way to do that in AutoIt unfortunately.

[James]

Without the need for a special .dll and/or lots of scripting for points and paths. Its going to be very hard!

[Achilles]

I suggest you google for floodfill dll, or flood-fill dll.

Do you have any examples of how to use this .dll?

Edit: I mean with autoit, I found some people using this but I don't know how I would translate it to autoit language...

Maybe an easier way would be to prefill the areas with different colours and then change/swap the colour of the high-lighted area?

I'm not sure what you mean... Would your idea include me having a bunch of different images? 'Cause if not, then I don't know how I would prefill the areas...

[James]

Pixel Searching maybe? Its really hard to find away without images.

I only meant that you should search for floodfill and dll to find a dll which has a floodfill function.

I found this API which I would think could be the best option

floodfill API

but I haven't got ime to play with it now.

Maybe you will find something searching the forum, in particular I suggest you search for posts by Zedna about graphics and drawing because I think he is very good at this sort of thing.

I couldn't get the Floodfill api to work so I've written a dll to do floodfill. I think it will do what Piano Man wants, and could be usefule to someone else.

It has a single function

Function Fill(ctrlHandle,xcoord,ycoord,brushcol,bordercol,ffilltype)

The filltype has to be 1 at the moment untill I either fix or or find it works with 0. (Haven't tried it yet!)

1 means fill the area bordered by colour bodercol, starting at the point xcoord, ycoord, and using a brush colour of brushcol.

Here is a sample program which uses the gif in Piano Man's OP

Documentation is not my forte. To use the program have the dll in the @ScriptDir, change the colour value in the edit box (RGB) to what you want, and click in the area to be filled.

#include <GUIConstants.au3>
Const $FLOODFILLBORDER  = 0, $FLOODFILLSURFACE = 1
Opt("mousecoordmode",2)
$gg = GUICreate("floods",700,800,10,10)
$pic1 = GUICtrlCreatePic("South_America_Map.GIF",0,0, 0,0)
$ed = GUICtrlCreateEdit("ff0000",520,50,170,45)
$ed2 = GUICtrlCreateEdit("",520,100,170,45)
GUICtrlCreateLabel("Fill colour",520,25)
Guisetstate()

While 1
    $msg = GUIGetMsg()
    
    If $msg = $GUI_EVENT_CLOSE Then Exit 
    If $msg = $pic1 Then
        $fcol = Dec(GUICtrlRead($ed))
        
        $mp = MouseGetPos()
        DllCall("floodfill02.dll","int","Fill","hwnd",GUICtrlGetHandle($pic1),"int",$mp[0],"int",$mp[1],"int",$fcol,"int",0,"int",1)
        
    EndIf
    
    $mp = MouseGetPos()
    GUICtrlSetData($ed2,$mp[0] & ', ' & $mp[1])
WEnd

Any suggestions on how I can make the image refresh automatically?

EDIT: Replaced line GuiSetState() which somehow I had deleted.

Here is working sample for FloodFill without external DLL

#include <GUIConstants.au3>

Opt("mousecoordmode",2)

$gui = GuiCreate('Map of South America', 516, 761) 
$pic1 = GuiCtrlCreatePic(@ScriptDir & '\South_America_Map.gif', 5, 5, 506, 751) ;Image is attached
GUISetState()

$pic_hWnd = ControlGetHandle($gui,"",$pic1)
$pic_hdc = DLLCall("user32.dll","int","GetDC","hwnd",$pic_hWnd)

$hBrush = DllCall("gdi32.dll", "long", "CreateSolidBrush", "int", 0xFF00FF) ; fill color
$obj_orig = DLLCall("gdi32.dll","int","SelectObject","int",$pic_hdc[0],"int",$hBrush[0])

While 1
    $msg = GUIGetMsg()
    
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
    
    If $msg = $pic1 Then
        $mp = MouseGetPos()
;~         DllCall("floodfill02.dll","int","Fill","hwnd",GUICtrlGetHandle($pic1),"int",$mp[0],"int",$mp[1],"int",0xFF00FF,"int",0,"int",1)
        DllCall("gdi32.dll","int","FloodFill","int",$pic_hdc[0],"int",$mp[0],"int",$mp[1],"int",0x00) ; border color
    EndIf
WEnd

DLLCall("gdi32.dll","int","SelectObject","int",$pic_hdc[0],"int",$obj_orig[0])
DLLCall("gdi32.dll","int","DeleteObject","int",$hBrush[0])

Very good Zedna, that's much better. I couldn't work out how to do that.

Now I noticed my name in your post. Thanks for compliments martin.

GUIGetMsg() is only returning mouseevent codes (-7, -8, -11 = mousedown, mouseup, mousemove). It's not returning the control ID.
