Hi, I am getting nowhere with using dbText. I always get a compile error when I try to use dbText to display some text.

If I use dbText (0,0,"Hello"); this works fine but I wish to display the camera position x,y,z.

Below is my code, I am playing with the tutorials to learn so modifying as I understand things:

[// get camera x position
xval = dbCameraPositionX (0);
dbStr$ (xtext, xval);
// camera position co-ords
dbText ( 0, 0, xtext);]

The help file on Dark GDK give the commands and syntax but not sure as to the syntax:

eg: help file says - char* dbStr$ ( char* szString, int iValue )

so do I type: char* dbstr$ ( char* xtext, xval);

I have tried all ways and still get error when compiling such as:

'main.cpp(78) : error C3861: 'dbStr$': identifier not found'

or

'main.cpp(78) : error C2440: 'initializing' : cannot convert from 'int' to 'char *'

I am at alost as to print the text I want - such a simple task surely?

Regards.

Gentlemen, many thanks for your code snippets and help. I tried both and the latter one worked so not sure why the former didn't.

Will play with the former as to why it isn't working and still giving the same errors.

As said the latter does and I tried a font change and it responed.

So once again many thanks gents for putting me back on the track.

Regards

This is the problem, the examples do not work or give errors which do not make sense or is not clear from the help file syntax.

From your snippet jezza and the change of $ sign line 2:

dbStr (char* xtext, xval); - gives these errors:

error C2144: syntax error : 'char' should be preceded by ')'
error C2661: 'dbStr' : no overloaded function takes 0 arguments
error C2059: syntax error : ')'

so no idea as to why.

I upgraded Express to SP1 would Dark GDK need to be upgraded, just a thought.

cheers.

i use commands similar to :



to display camera/mouse/keypressed commands all the time

The above code will set an integer "mouseclick" to hold the values of the mouse buttons being clicked, and spritecollide holds the value of any sprite that comes into collision with "iMySprite", then we simply display the values of the Camera X, Y, Z positions, and the values of "mouseclick" and "spritecollide" using the dbText() function, obtaining its char* value by calling the dbStr() function to convert the integers "mouseclick" and "spritecollide" aswell as those returned by calling dbCameraPosition() to char* values useable by dbText()

If it ain't broke.... DONT FIX IT !!!
