Greetings! I recently made my first game thanks to GDK (woohoo!) and am looking into adding text and eventually a menu/HUD system to it. However I can't get dbText to work. The code in question looks like this:



This doesn't display at all. I think it may be hidden behind the background and sprites, but if so, how can I change this? I also tried adding it after dbSync() and calling dbCLS() afterward and it didn't change anything. Do I need to set a font before dbText will work? I'm not sure why this isn't working. Thanks for your help!

1: Try calling dbSync() TWICE followed by a dbWaitKey() or something along those lines to see it print.

Also remember if the 3d stuff is going - imparticularlly the backdrop is on - the screen gets cleared each go around... so you need to - or maybe should at least consider - writing the same stuff to the screen - to the same positions etc - each loop.

I've recently started putting GAME stuff above my sync, and print stuff below my sync - no reason - but keeps it together.

Figured it out: the text was being drawn to the background buffer before the background and sprites, so it was immediately overwritten. I wrote a little text handler that makes an image from a bitmap that you can write text to and displays it. It's not perfect, but it gives you an image of the text that can be displayed as a sprite. Just pass it a string and an image of that string will be saved as image number 90. Then you can use dbSprite() in your main loop to make it draw wherever you like.
