I want to make a block different from the other ones just changing his instance variable, but I want to change the variable of a random object (instance). And I want to repeat this at the end of each level, with a function.

I want to know if I can make something to my project for always being in fullscreen, I mean without black lines.

I want to do something like when a sprite changes his animation I set his HitPoints to 20, but only when changes, not when he is with that animation. My problem is that it sets the value to 20 all the time.

You can try this:

> Turret NOT has target
     Enemy instVariable="specific value"   -> Turret acquire target Enemy
[/code:1bept8e7]

If you have "Add turret target Enemy" event, you need to remove or disable it.

Edit:

Thank you it really works, I make little changes and it works thank you a lot!!!

How I make a turret that only shoots to objects with a specific value in an instance variable?

Hey Darth, the answer is yes.

The only reason this may change in the future is if Scirra decide not to host the signalling server (used to connect machines) which I cant see happening any time soon.

In a worse case scenario you would have to set up your own signalling server (think it sells for about 20 bucks on the store here).

Ok thank you a lot for answering fast I see your projects and are very interesting .

I want to know that if I create a multiplayer game and later I export it and upload to the web, the multiplayer will still working.

I want to make a map that is divided into squares, and each square has its own properties like, trees, water, of the place.

I want to create a group of objects in the layout, like a new menu, but I don't know how to create all the objects at the same time, I mean with one "create" action.
