Hi Jonathon,
Rather than trying to turn GL primitives in to an image to use with a
Sprite, you could also make a Sprite-like class for the various shapes.
This can get tricky if you want to rotate them, as you'll have to add your
own math to do that work, but as an example I'll post a simple Rectangle
class below. You can make similar classes for a variety of shapes:
class Rectangle:
def __init__(self, x, y, width, height, color=(255, 255, 255, 255),
batch=None, group=None):
self._x = x
self._y = y
self._size = [width, height]
self._color = color
self._batch = batch
self._group = group
self._vertex_list = batch.add(6, GL_TRIANGLES, group, 'v2f', 'c4B')
self._update_vertex_list()
def _update_vertex_list(self):
x = self._x
y = self._y
w, h = self._size
one = x, y
two = x + w, y
three = x + w, y + h
four = x, y + h
self._vertex_list.vertices[:] = one + two + three + three + one + four
self._vertex_list.colors[:] = self._color * 6
@property
def width(self):
return self._size[0]
@width.setter
def width(self, value):
self._size[0] = value
self._update_vertex_list()
@property
def height(self):
return self._size[1]
@height.setter
def height(self, value):
self._size[1] = value
self._update_vertex_list()
