Could it be that the factory is in a collection loaded with a collection proxy and the things it is trying to collide with isn’t part of this collection? Read about physics worlds [here](http://www.defold.com/manuals/collection-proxy/#_worlds).

oooh, i am having the same problem but with a game object tilemap spawned with the factory and the player\_factory that spawns the player go. they don’t seem to collide, the main node on the image is spawned with a collection proxy so for the gui to get input i had to add on the go root acquire input focus. but i have a small print on my player and it is getting messages and inputs but not collision messages, just DEBUG:SCRIPT: player getting messages hash: [animation\_done] table: 0x0240e3a83ee0 url: [game:/instance1#sprite], any help please ?

edit, i don’t know what happened but i just roll back to a yesterday commit and got it working again, have no idea what was the problem.
