I'm trying to make this short game. The player no longer moves- when move is selected nothing happens it just says "move east". when I type "look at" object it returns no description. Objects have descriptions written in them to be printed when look at is typed... So I have no idea what is going on. In teaching myself how to use this - my goal was to make an object in the laboratory in a container (called Conservatory) which can be taken and then "switched on" once it is in your inventory. When it is switched on the parent is removed from your inventory and a new object is placed in your inventory. The idea was that you are turning this object into another object. In the game the player is meant to get a pebble and eventually turn it in to a coin using a spell which turns the switch on. But I can't test because now it seems nothing works.

And do I have to construct the inventory system? I thought it was built in? It should just be coded in that Tab brings up inventory list and inventory is an object in player. Anyways I have a lot to learn, but I can't test anything cause it just doesn't respond in play test. I probably did one small thing which has crashed the whole game or something.

If your code it not too long, and from the sounds of it, it isn't, yet....
Just post it here and someone can help you find the simple error...

What's the code you've got so far? I think people might be more able to point out where it's going wrong if we could see what you've got.

You say Inventory is an object in player… I assume that means that you're creating a separate inventory system, rather than using the built-in one?
I've got a couple of guesses what the problem might be, but without seeing your actual code, I can't offer any practical advice.

first, make a new game, and see if quest works fine, or if it's still messed up, then try removing quest and re-download and re-install it, and see if it then works, or not, let us know what happens.

If you don't see your inventory, check your settings. If you're using the online editor, it's somewhere in the game tabs. You're on your own if you use the offline.

There are tutorial videos for Quest on Youtube. They are very short and simple. But, they includes making exits and looking at things.
