It shouldn't be a problem either way, as you can see running these two
variants in the cocos/test directory
import cocos
cocos.director.director.init()
cocos.sprite.Sprite("car.png")
cocos.tiles.load_tmx("road-map.tmx")
or
cocos.director.director.init()
sprite = cocos.sprite.Sprite("car.png")
cocos.tiles.load_tmx("road-map.tmx")
There's the possibility that the combination of resources loaded in
"untitled.png" and "untitled.tmx" be problematic.
To be more specific theres a need to know:
- which pyglet version (changeset if from repo, there are changes in
texture atlas there)
- which cocos version (sha1 if from repo)
- representative samples of "untitled.png", "untitled.tmx" and any
resource used in the .tmx
