I am a complete noob to dark gdk and I know you can print strings on the screen. So all I want to do is just print the camera position and angle because in the game i'm making i want it to do something when you go through a door. Like

if (dbcamerapositionX > ____){

play sequence ___

}

something like that. Help Please.

I had a lot of trouble with this but I managed to sort of figure something out.

So to print the camera position you'd first need to make the proper variables



x = dbCameraPositionX();

y = dbCameraPositionY();

z = dbCameraPositionZ();

Then you'd need to make it into a string.





char CameraPositionXString[5];

sprintf(CameraPositionXString, "%s", x);

char ThingToPrint[25] = "X = ";

strcat(ThingToPrint, CameraPositionXString);

The if this doesn't work, try using %d instead of %s

Then you have to print it

[/code]
dbText (10, 10, CameraPositionXString);
[code]
I didn't run this but it should work.

The regular float convertion (shouldn't it be float x = __ but nvm)x = dbcamerapositionX works fine thank you but i dont get the string convertion.

Also all it does is print (null)

Why not just use dbStr()?

It will convert a float or an int to a string.

Example:

+ Code Snippet

float foo = 3;
dbText(0, 0, dbStr(foo));

Or if you want to combine everything into one string and not use dbStr(), use printf() like the puppy of kosh.

Example:

+ Code Snippet

float x = 5, y = 10, z = 20;
int i = 100;
char sz_str[256];
sprintf(sz_str, "X = %f\r\nY = %f\r\nZ = %f\r\nI = %d", x, y, z, i);
dbText(0, 0, sz_str);

You can search google for everything that sprintf() can convert to a string. For example, it will replace the first '%d' in the format string with the double or integer form of the first parameter.

#ifdef _DEBUG
FixBugs(All);
#endif

ok this is making me more confused heres a print of my code like don't just rewrite it i just want to show you like what I have so far

+ Code Snippet

float fCameraAngleX = 0.0f;
	float fCameraAngleY = 90.0f;
	float x = dbCameraPositionX();
	float y = dbCameraPositionY();
	float z = dbCameraPositionZ();
	char CameraPositionXString[5];
	char ThingToPrint[25] = "X = ";
	char strTemp[256];

	while( LoopGDK () ){

        // Print the fps And poly count
		sprintf( strTemp, "Frame Rate : %d ", dbScreenFPS ( ) );
		dbText( 10, 0, strTemp);
		dbText ( 10, 30, dbStr(dbStatistic ( 1 ) ) );

		// Print camera angle
		sprintf(CameraPositionXString, "%s", x);
		strcat(ThingToPrint, CameraPositionXString);
		dbText (10, 15, CameraPositionXString);

and that is so far it it gets messed up and says that i have an error with windows (it crashes) and it gives me an error support message thing.
