puzzle when using D3DXCreateFontIndirect
Author
Hi,everyone.
my question is when i create a 2d text,it always on the topest of all the scenes whatever the render state i use, and i create the 2d text as follows,
Author
Maybe i haven't tell the problem clearly, this is the code i do it.
When use LOGFONT struct,the text maybe cover by the lines, but use the D3DXFONT_DESC struct, the text always on the topest, how can the text be covered by the lines when i use D3DXFONT_DESC struct? because when use the LOGFONT struct two draw 2d text is slower.
thanks.
