The parameter says that it takes a pointer to a character or character string.



Or something like that. Just don't reuse the buffer in the same operation.

String concatenation isn't an easy thing to do in C++ like it is in BASIC.

I've also tried to do this and what I ended up doing was create a temporary character pointer array, concatenating the necessary information onto it and then passing that into the dbText function. Not fun... so since it was just for debugging, I didn't spend a lot of time on it and just went with having the values on individual lines.


The one and only,

#include <string>

std::string tmp = "Camera: ";
tmp += camx; tmp += ", "; tmp += camy; tmp += ", "; tmp += camz;
dbText(x, y, (char *)tmp.c_str());

If you get problems, remove the (char *) in the call to dbText.

This is how I usually do it ..



Use %d for integers or %f for floats.

Hmm. I don't think those errors are coming from the code I posted, if you are using it exactly as shown. Using sprintf() in this way is pretty standard 'C' coding. Are you sure the buffer you are allocating is big enough to hold the entire string? Are you using the correct variable types to match up with the format specifiers (%d for integers, %f for floating point etc.)

If you're familiar with cout then you may find that stringstreams are a bit easier to use:



Streams are fun!
