Add push out of custom obstacles feature in "rex_pushoutsolid" behavior.
Try this new version.
Ah man, you are a star! Thank you so much!
But I'd request couple more modifications. One is small: pushing out at slightly different angle - what this would do it would let player keep on moving even when is pressing against solid. This would improve the gameplay a lot. And second, if you'd be able to add "mass" to it, so bigger mass pushes objects with smaller mass harder, that would be insane!
