I used the bold version of https://fonts.google.com/specimen/Playpen+Sans/about?preview.text=score%201234
let font = asset_server.load("fonts/playpen_sans_extrabold.ttf#mesh");
commands.spawn((

Some fonts produce a Glyph2MeshError
when you attempt to load them. For example, Inter.
Other fonts, like Courier, don't seem to render at all, even though they load properly.
Hi. Thanks so much for making this library.
I was wondering, are there any plans to support Bevy 0.13?
The crate uses a global mesh cache.
It is not being cleaned up at all, resulting to polluted cache, when:
My bad... I forgot to load the regular bevy Font while upgrading to 0.12 ๐
The library possibly fails to compile on MacOS:
warning: ttf2mesh/ttf2mesh.c:54:10: fatal error: 'malloc.h' file not found
warning: #include <malloc.h>
warning: ^~~~~~~~~~
warning: 1 error generated.
There's a related stackoverflow question about malloc.h at https://stackoverflow.com/a/56463133/499839
One option would be to transpile ttfmesh.c into rust by https://c2rust.com/. That could also fix #11
Currently crate uses its own asset loader for a font.
This may be desired eventually too, but it may overlap with bevy standard loader. It could not be used, since there is no way to expose the font-bytes (needed for ttf2mesh
).
When I add in the TextMeshPlugin then any 2d text ( https://github.com/bevyengine/bevy/blob/main/examples/ui/text.rs ) disappears. I am guessing that it's just that the 2d text is getting upset by a different font loader.
It would be great if I could use your awesome 3d text and also have some 2d ui (like fps and other HUD info). Took me a little while to track this down that this was the cause.
Not sure what type of asset ends up getting loaded in this case, but Res<Assets<TextMeshFont>>::get
yields None
without #mesh
, so of course nothing would be displayed.
This is the result of me misreading the docs/examples but I feel like something should blow up or yell at me for this.
Currently, the size unit is just an arbitrary number (SizeUnit::NonStandard
) - some standardized way should be defined.
Is there any chance WASM will be supported? Thanks.
An example/
file, that would contain multiple different texts displaying the rendering result of various TextMesh
options.
