Api changes and other compatibility notes from previous version

cocos 0.6.4

This is the first release supporting pyglet 1.3+

Imports in cocos library are more specific, so user code that were doing from cocos.somemodule import * may fail to find some symbols. To fix that user code, add explicit exports as needed.

MapColliders classes changed API to be more useful and clear.

• RectMapCollider moved to his own module, mapcolliders.
• RectMapCollider was renamed to RectMapWithPropsCollider.
• The new RectMapCollider handles a simpler collision case, when all tiles are solid: now no need to set cells properties to signal a cell border should not be walked over.
• TmxObjectMapCollider now handles AABB collision with any TmxObject that can be loaded.

Rect.intersects() now it only intersects if some interior points overlaps.

Removed Scene methods push_all_handlers() and remove_all_handlers().

In ScrollingManager two methods have been renamed, the old name is still valid but will be removed in the future:

• pixel_from_screen() -> screen_to_world()
• pixel_to_screen() -> world_to_screen()
