Das Tank: credits.cpp File Reference

int boxOpposite ( int boxDir )

Return a direction code which is 'opposite' the one passed in. This is used by the code which draws the credits background (box random walk). This is basically a look-up table and could possibly be made more elegant.

Definition at line 394 of file credits.cpp.

int Credits	(	gcn::OpenGLGraphics *	graphics,
		gcn::ImageFont *	font
	)

Scroll credits on the screen while displaying an interesting background. The credits file is read from disk, and displayed using a system of two 'page buffers' which are scrolled upwards, and periodically refreshed with new text and repositioned once they reach the top of the screen.

Todo:: This function reads from the disk each time the page buffers are reloaded. This should be changed to maintain a memory buffer of the entire credits file.

int creditsReadPage	(	FILE *	file,
		char *	page
	)

Read in a page of text from the credits file on disk. This function depends on the text file being formatted with newline characters at the end of each line only, and may fail if used with text files formatted on other systems (Apple, Linux, etc.)
