The player keeps falling down in example 1.
What do I miss?
It shouldn't be falling. Did you add Game Creator on a brand new project? Also, it's recommended that you use Unity 2018.4 LTS, which is the latest stable branch. Unity 2019.3 is not really recommended for production and is quite unstable.
oh It was my mistake. The physics setting (collision layer) has been overrided by other assets. I fixed it and works. Thanks you.
Glad to hear that :-) I'm closing the ticket then. Cheers!
