Just use the Count expression.

When Enemy.count is 0, level is accomplished

For any other useful expressions, read this, I hope it will help :

You can also use the "Function" object to save all those variables in webstorage.

give it a look:

https://www.scirra.com/manual/149/function

You just need to do the following:

[Function | "savemygame"] : (save all the variables in webstorage)

Then you can use that function as an action like this:

[On tap on SaveButton] : (call "savemygame")

The action (call "savemygame) will repeat all the actions defined in the [Function | "savemygame"]

It works perfectly, but pay attention to performance, because I saw that loading my game made everything slower and I had to revert to webstorage...

***UPDATE*** I've just read that some "save" bugs were fixed on R197.

I reverted to webstorage when the last release was still R196, so I'll give a second chance to the save action , maybe those bugs were the performance killers.

You could create a "Loader layout" that will be the first layout of your project that will do the following:

[On start of layout] Load game

[On load failed] Go to 'TitleLayout' (if you play for the first time)

Also, if you save in GameLayout loading the game will bring you to that layout, but I am sure you want to make it start from the Title screen so add this condition to every eventsheet:

[On load complete] go to 'TitleLayout'

In this way you can save anywhere at anytime, just remember not to set that condition to the TitleLayout event sheet

Ashley Thank you so much for your effort in producing such new releases!

Construct2 is already powerful, and every release adds a pinch of awesomeness.

How is that possible? Enemyname.count is a specific system expression that gives you the value of the actual number of "enemy" sprites on your layout... Can you submit a .capx?

Oh right. Excellent reply volkiller730

Post your feedbacks about the new 198 release.

I found that my mobile game is way smoother even on crappy devices!

You could create an event that subtracts 1 from your variable every time an enemy gets destroyed.

Something like this: [[Enemy] On Destroyed] : |Subtract 1 from Global variable|

I've tried many solutions but it still gives the strange delayed movement.

It was meant to just try if the easiest condition worked

At this point the only possible problem is the code.

Try to do a simple "on start of layout show interstitial"
