barrage of bullets in shooting games. (For example Progear, Psyvariar,
Gigawing2, G DARIUS, XEVIOUS, ...) This module parses and executes
BulletML scripts in Python. All data structures in it are
-renderer-agnostic.
+renderer-agnostic. A sample renderer for Pygame is included. The full
+API documentation is contained in its Python docstrings.
In addition to the standard BulletML XML format, this module supports
-an equivalent YAML format. See bulletml.bulletyaml for more details.

-Finally, three simple collision routines are provided:
-bulletml.overlaps for stationary circles, bulletml.collides for moving
-circles, and bulletml.collides_all for one moving circle against many
-moving circles.

+routines are provided, bulletml.overlaps for stationary circles and
+bulletml.collides for moving circles.

Basic Usage:
from bulletml import Bullet, BulletML
- doc = Bulletml.BulletML.FromDocument(open("test.xml", "rU"))
+
+ doc = BulletML.FromDocument(open("test.xml", "rU"))
player = ... # On your own here, but it needs x and y fields.
rank = 0.5 # Player difficulty, 0 to 1
+
bullet = Bullet.FromDocument(doc, x, y, target=player, rank=rank)
bullets = [bullet]
...
for bullet in bullets:
- bullets.extend(bullet.step())
+ bullets.extend(bullet.step()) # step() returns new Bullets
...
For drawing, you're on your own, but Bullet instances have a number of
from bulletml.impl import Bullet
from bulletml.collision import overlaps, collides, collides_all
-VERSION = (2,)
+VERSION = (3,)
VERSION_STRING = ".".join(map(str, VERSION))
__all__ = ["VERSION", "VERSION_STRING", "Bullet", "BulletML",
"overlaps", "collides", "collides_all"]
