Is there an extra #include < > needed for using certain commands in DarkGDK?? I'm trying to use dbText to display x,y,z camera coords on the screen. I have a variable CPX representing the camera X location. Using dbStr$(CPX) in the dbText command returns the following error: 'dbStr$': identifier not found. Yet it's listed in the DarkGDK help file?



Thanks.

remove the "$" so its dbStr() instead of dbStr$().

Wow thanks. But how was I supposed to know that when the .chm example lists Str$()?

Thanks again.

DBPro documentation. They left some of it in there. They didn't do a wonderful job with it.

Also, you might try using sprintf to print variables. Check it out:


The advantage here is that you can label the text output. That %f stands for a float, though you can have %c for a char, %d (or %i) for an int.



Experiment!

$ (ding) isn't a valid character for an identifier in C/C++. The only valid characters are 0-9, a-z, A-Z, @ and _. A numeric value cannot be used as the first character.
