So I've made a little 2d game... The goal is to stay on the screen for as long as possible and everything runs fine, but now when I want to show the player his score I can't figure out what to do.
I want it to be like this:

while(LoopGDK())
{
score += 1;
//now I need a way too delete old text
//The print a new one with the text "score: " followed by the variable score

//rest of loop
}

I've tried dbPrint and dbText but I can't get them to show up (maybe because of background sprite?) and even if they did show up I don't know how to include a variable or delete the text again before it's printed again.

Any help?

oh on a side note, you are increasing the score once every loop, if you have 60 FPS, then you are increasing score by 60 every second, the number would be increasing very fast and it would look retarded not to mention that your FPS may get up to 1k-2k, you better make a timer and increase it by an ammount after some time

I have the same problem, i tried

dbText(x,y, dbStr$(scoreval));

And it dont work. Does not recoginize dbStr$ (even though i got it from the help file!!) Do i need to #include somthing else to get that working?

There is no dollar sign after dbStr. (Part of the help was copied from Dark Basic Pro, that's why it has sometimes unnecessary dollar signs.)

But in any case, do not use dbStr like this because it will cause a memory leak. Dark GDK functions that return strings create a new string every time they are called. You should store the returned string pointer and then delete[] it after use, which is uncomfortable. You are much better off with sprintf or sprintf_s, as recommended above by Hassan. That also gives you the possibility to include the number into a string, e.g. "The score is: %d", which would require even further hassle with dbStr.

I've not seen the sprintf command before, i'll look into it. Thanks for the help.

Thanks I got it to work but it's still drawn behind the backdrop sprite, how can I draw the text over the background?

Try using dbDrawSpritesFirst before the main loop.

GDKUtilities, a utility library for DarkGDK, avaliable here
