I am trying to figure out how to use to loops like in dark basic pro. Practicly i am trying to create a small menu. If the user presses enter, the game will jump to the game: tag. But i can't do it using C++ and GDK. Like in DBPro i had to do something like:

+ Code Snippet

Load Image "folder/image.png",1
Paste Image 1,0,0
do
if Upkey = 1 then goto game
sync
loop

game:
'Display, camera settings
'Load what i have to load here
do
'move objects, if, w/e all sorts of stuff
sync
loop

In GDK i found no possible way of doing it.. If i load an image, and paste it before the "while(LoopGDK())" and then use dbWaitKey(); the image doesn't get paste until i press dbWaitKey... and i cannot use if or anything else unless they are in the loop. Pff any ideas on how to get around that?

You need conditions for your loop. Let's say you want the enter key to continue...

+ Code Snippet

dbPasteImage(...);
//A 'while' loop to wait until the enter/return key is pressed
while((dbLoopGDK())&&(dbReturnKey()==0)){dbSync();}

//A new loop that will do whatever else you want
while(dbLoopGDK()){
     //Your code
}

Alternately, you could use a 'do' loop.

+ Code Snippet

do{
     //Whatever you need to get done
     dbSync(); //Can't forget to refresh the screen!
     while(dbLoopGDK());
}

My site, for various stuff that I make.
