Using custom fonts with the NDK

Hi. I'm developing a simple game with the NDK and would like to know if anyone knows how i can load a custom font to the playbook to use in my game. I've tried copying it with the rest of the resources and loading it from there, but when I try to load the font with the "FT_New_Face" function I get an error, and the error code that it returns is 1. I tried with different fonts ( ttf and otf ) and the result is always the same. Does anyone know how i can solve this, or even if this is possible? Thanks.

Re: Using custom fonts with the NDK

Just to confirm, I tried using bbutil_load_font() and bbutil_render_text() with my packaged TTF fonts and get "Error loading font."

Re: Using custom fonts with the NDK

Hey superdirt.

 

I suspect you did not specify a proper path to your ttf/otf. How does your bar-descriptor source look like for your font asset?

 

And what path do you specify for bbutil_load_font?

Re: Using custom fonts with the NDK

Hi dtomilovskiy

 

In my case, I loaded the font as a normal resource. In my bar-descriptor.xml file, the reference to the font is as follows:

    <asset path="resources/BPdotsSquare.otf">BPdotsSquare.otf</asset>

 

and the line of code i'm using to load the font is this one:

        _font = bbutil_load_font("/app/native/BPdotsSquare.otf", 15, dpi);

 

After calling the bbutil_load_font function, I get the error that superdirt described "Error loading font.". I dug a little inside the bbutil_load_font function, and the point where it fails is when calling the FT_New_Face function.

 

I don't know if this is relevant or not, but I'm trying to run this on the Simulator.

Re: Using custom fonts with the NDK

Line in bar-descriptor:

 

<asset path="BILLH___.TTF">BILLH___.TTF</asset>

 

Code for loading:

 

	fontbig = bbutil_load_font("/app/native/BILLH___.TTF", 35, dpi);

 

 This gives me the error:

Error loading font /app/native/BILLH___.TTF

Re: Using custom fonts with the NDK

I found the problem on my end, a typo. The path should contain no leading "/":

 

"app/native/BILLH___.TTF"

Re: Using custom fonts with the NDK

After seeing your post I checked my code and had the same typo.

 

Thanks for the insight  Smiley Happy
