Detailed Description

Text using objects.

This is similar to tilemaps, in that the glyphs are loaded into object VRAM first and pointed to by the objects. Unlike tilemaps, though, variable-width fonts are possible here. The members of the surface member are used a little differently here, though. the pitch is used as an index to the current object, and width is the number of objects allowed to be used for text.

Function Documentation

void tte_init_obj	(	OBJ_ATTR *	obj,
		u32	attr0,
		u32	attr1,
		u32	attr2,
		u32	clrs,
		u32	bupofs,
		const TFont *	font,
		fnDrawg	proc
	)

Initialize text system for screen-entry fonts.

Parameters:

	obj	Destination object.
	attr0	Base obj.attr0.
	attr1	Base obj.attr1.
	attr2	Base obj.attr2.
	clrs	colors to use for the text. The palette entries used depends on attr2 and bupofs.
	bupofs	Flags for font bit-unpacking. Basically indicates pixel values (and hence palette use).
	font	Font to initialize with.
	proc	Character plotting procedure.

Note:

The TTE-obj system uses the surface differently than then rest. Be careful when modifying the surface data.

Todo:

Multi-bpp.
