But still I recommend to use local variables, since too many global variables will be very confusing

Maybe you show us your example cause Webstorage is not connected with layouts.

As far as I can see there's no possibility to do this with the normal text object. But there are a lot of plugins out there that will help you!

For example this:

Or you use one single canvas object and change its colour.

yes, it picks all instances. But when you try to get an instance variable, it uses the object with the highest UID.

Actually you "just" need to find all the things that could be created/changed during the game and reset them to default.

Commands like "reset all global variables" will help you. Or you just reload the layout.

Your first problem:

Mouse-> Cursor is over object

Second:

As far as I know it always picks the last created instance. It's always good to be precise when picking objects.

Ashley: Is it just not supported or not possible? Would it be possible with a plugin?

I don't want to download them. Currently I'm planning to have a mobile app with cocoonjs. I was wondering if it's maybe possible to already store the images in the app but load them during gameplay, when needed.

Ashley : Could you give me a hint if this is possible?

I have really huge images and it would be awesome when I could load them while the game is running and the device is offline.

When Tom postet they had about 950k downloads. They hit the million a few days ago.

When your loginpage is in HTML and not in C2, why don't you just login first and then open the index.html from c2 (Where you could also check if you're logged in).

Yes, possible.

But C2 would just be the frontend of the game. You also need backend, server and database.

Time to develop the game for a very experienced programmer approximately 1 year with 40h/week.
