问题
I'm working on a project at the moment and I have been trying to change the fonts of the labels in the pyglet library to fonts that I found online but I couldn't get it to work. I tried searching online for an hour now and nothing seems to be working. Added some code for reference:
font.add_file('ZukaDoodle.ttf')
ZukaDoodle = font.load('ZukaDoodle.ttf', 16)
PlayLabel = pyglet.text.Label('Go', font_name='ZukaDoodle', font_size=100, x=window.width // 2,
y=window.height - 450, anchor_x='center', anchor_y='center',
batch=buttons_batch,
color=(0, 0, 0, 1000), width=250, height=130)

So the error is pretty simple. The loaded font-name is not ZukaDoodle, it's Zuka Doodle with a space. Here's a working executable sample:
from pyglet import *
from pyglet.gl import *
font.add_file('ZukaDoodle.ttf')
ZukaDoodle = font.load('ZukaDoodle.ttf', 16)
key = pyglet.window.key
class main(pyglet.window.Window):
def __init__ (self, width=800, height=600, fps=False, *args, **kwargs):
super(main, self).__init__(width, height, *args, **kwargs)
self.x, self.y = 0, 0
self.keys = {}
self.mouse_x = 0
self.mouse_y = 0
self.PlayLabel = pyglet.text.Label('Go', font_name='Zuka Doodle', font_size=100,
x=self.width // 2,
y=self.height - 450,
anchor_x='center', anchor_y='center',
color=(255, 0, 0, 255),
width=250, height=130)
self.alive = 1
def on_draw(self):
self.render()
def on_close(self):
self.alive = 0
def on_mouse_motion(self, x, y, dx, dy):
self.mouse_x = x
def on_key_release(self, symbol, modifiers):
try:
del self.keys[symbol]
except:
pass
def on_key_press(self, symbol, modifiers):
if symbol == key.ESCAPE: # [ESC]
self.alive = 0
self.keys[symbol] = True
def render(self):
self.clear()
self.PlayLabel.draw()
## Add stuff you want to render here.
## Preferably in the form of a batch.
self.flip()
def run(self):
while self.alive == 1:
self.render()
# -----------> This is key <----------
# This is what replaces pyglet.app.run()
# but is required for the GUI to not freeze
#
event = self.dispatch_events()
if __name__ == '__main__':
x = main()
x.run()
The key difference here is font_name='Zuka Doodle'.
Also, the alpha channel usually doesn't need to be higher than 255 since that's the max value of a colored byte, so unless you're using 16-bit color representation per channel, 255 will be the maximum value.
