Panda3d does not want me to load my font (that's in the same directory)... "OSError: Could not load font file: SatellaRegular.ttf"

Scripting Issues
#1

Greetings!

For the past few day, i have been developing a multiplayer shooter. Obviously, it needs some kind of gui. I wanted various fonts and font styles to be used so i tried to load a font and show some text with it.

However, it threw the following error at me:

OSError: Could not load font file: SatellaRegular.ttf

Amazing.
After a couple hours of scowering the internet i found absolutely nothing, so i decided to post here.

Below is a minimum reproducible example, and the font in question (though i dont think it will be of much help
The two files are in the same directory.
Minimum reproducible example:

from direct.showbase.ShowBase import ShowBase

from direct.gui.DirectGui import *
from direct.gui.OnscreenText import OnscreenText

class MyApp(ShowBase):
    def __init__(self):
        ShowBase.__init__(self)
        fontloader = loader.loadFont('SatellaRegular.ttf')
app = MyApp()
app.run()

‎

And finally the font(if you need it):
https://www.fontspace.com/get/family/9727g
*the website just opens a file dialog and downloads there

Hi, welcome to the community!

Could you share which version of Panda3D you are using, which operating system, and how you installed it?

#3

Panda version: 1.10.7
Python version: 3.8.2
Operating system: Microsoft Windows [Version 10.0.19041.685]
Installed using pip

My panda3d installations appears to be normal and executes other code perfectly well

#4

fontloader = loader.loadFont('SatellaRegular.ttf')

Name in code SatellaRegular.ttf and name file SatellaRegular-ZVVaz.ttf

do you think there is a difference?

I changed the name and booted without errors.

Still same problem, i believe that it is a problem with my installation
Here’s the full error log:

Traceback (most recent call last):
File “C:\Users\lazar\Desktop\Panda3d.py”, line 58, in
app = MyApp()
File “C:\Users\lazar\Desktop\Panda3d.py”, line 20, in init
fontloader = loader.loadFont(‘SatellaRegular-ZVVaz.ttf’)
File “C:\Users\lazar\AppData\Local\Programs\Python\Python38-32\lib\site-packages\direct\showbase\Loader.py”, line 638, in loadFont
raise IOError(message)
OSError: Could not load font file: SatellaRegular-ZVVaz.ttf

#6

And the file is located in C:\Users\lazar\Desktop\Panda3d.py, I presume?

Are there any other error messages?

Is there a particular reason why you’re using the 32-bit version of Python and Panda3D instead of the 64-bit version?

#7

Are you new to Windows? No spaces, no hyphens in the path. no, no. :stuck_out_tongue:

#8

1- Yes, it is in fact located there

2- No, this is the only error message

3- I dont remember specifically, but it had something to do with library support, and im too scared to change it now

#9

One last thing to try before I see if I can manage to install a 32-bit build of Python somewhere and see if I can replicate it. Try loading it via the full path, like so:

loader.loadFont('/c/Users/lazar/Desktop/SatellaRegular-ZVVaz.ttf')

I really do recommend using a 64-bit build. We only have the 32-bit build available for extremely old computers, and since there are so few people using it, there may be bugs that could go unnoticed.

#10

Oh God

loader.loadFont('SatellaRegular.ttf')

And change the name for the file.

SatellaRegular.ttf

Problem:

SatellaRegular - ZVVaz.ttf

In the hyphen

#11

Wait a minute, this shouldn’t be a problem, are you by any chance using some IDE?

#12

Thank you very much! I took the time to switch to 64 bit and now it works!

On another hand, i feel really bad for people with 32-bit x86 emulators

#13

All right, it may be a bug in how we created the 32-bit build of Panda. I’ll look into it. Thanks for bringing it to light!

#14

My previous installation was janky so take it with a gran of salt :sweat_smile:

#15

For the record, I’m not having any issues loading the font in an installation of 32-bit Python 3.9.1 with Panda3D 1.10.7 installed via pip.

#16

Interesting. Maybe its something else? I dont know

#17

If you want it to work, just do the following:

from panda3d.core import Filename
fontpath = Filename.fromOsSpecific("path/to/font.ttf")
font = loader.loadFont(fontpath)
