Thanks for help and suggestions, will try those. ......May I ask what version of Cocos Creator you are using? Maybe I'm wrong, but i think there could be an issue with 1.4.2, like, i open up my other game, and I try to preview in Google Chrome, and get a blank page with the below message:
There's nothing in scene to preview. Add something to the scene now!
I've tried to open another game, and try to import tmx into tmx renderer component, preview in firefox browser, and still it doesn't show up....... Very confusing...........God Bless.....
