Hello,
i want to create a damage amount effect (You know, like in RPGs or MMOs where the damage amount shows up on a hit).
So my plan is to texture a plain with the damage value.

How can i make this?

One way would be
- Draw Text
- Get Image at this position
- Texture Object with this image

but i dont want to use getimage, is there another way?

Thanks.

Use a bitmap font system; those inherently tend to draw the resulting text to an image (usually through blitting rather than rendering though).
Using the built-in text functionality of DGDK, no, I don't think there's any other way than that, although you can get get a 3D coordinate's representation in screen space and just position your (normal 2D) text accordingly.

Because Oct(31) = Dec(25)

Now you can set a camera to an image and use dbSetCurrentBitmap(-Camera Number) to render directly to the camera surface. You will need to download the Unofficial Update.

+ Code Snippet

// Dark GDK - The Game Creators - www.thegamecreators.com

// whenever using Dark GDK you must ensure you include the header file
#include "DarkGDK.h"

// the main entry point for the application is this function
void DarkGDK()
{
	// create a camera image render target surface
	dbMakeCamera(1);
	dbSetCameraToImage(1, 1, 128, 480);

	// draw directly to the camera surface
	dbSetCurrentBitmap(-1);
	dbCLS(dbRGB(64, 64, 64));
	dbCenterText(64, 0, "MENU");
	dbCenterText(64, 0, "____");

	dbSetCurrentBitmap(0);
	dbDeleteCamera(1);

	dbPasteImage(1, 0, 0);

	dbWaitKey();

	// return back to windows
	return;
}
