Create a "Wait 0 " action right before you call zorder().

How exactly do you save your variable? WebStorage?

Put all sprites on your map in a family. Then make a function you call everytime the player changed something on the map:

foreach spritefamily

ordered by spritefamily.Y ascending

Spritefamily move to top of layer

maybe you'll find them here: this.runtime.get_all_globals

I think I know the problem, but it's hard to explain for me. But I'll try.

When you touch the button, while paper is playing, construct notices the touch and sets the button's animation to rock. Now construct goes on checking for events (upper events before lower events, since it's a script language). Two events later it checks for "Animation "rocks" is playing. Since we set the animation to rocks right before, this event is also triggered and sets player back to "rocks".

I'm not 100% sure about the solution, but try this: Make A System->Wait 0 event right before changing to another Animation.

Hey,

it's really dirty what you're doing there! You can't access the global variable, cause it's stored somewhere in the runtime.

What exactly you want to do?

Maybe you can try and tell us where you're stuck. PHP and especially AJAX is not easy for beginners. Try to learn some basics and then try to get as far as you could get with the tutorial. I'll help you to fix all your problems, but I'm not willing to do other peoples work.

You could also use "Wait 0" after creation and still use a sub event.

You should check on every start of the game, if the game was played on this device before. If not, set the variables to default values.

What exactly you want to know? There a lot of things you have to know to do this. You need to learn PHP, MySQL and the AJAX technology.

How you want to make a login system without saving the data in a database? You need the database to make sure if players name/password are correct.
