I'll try it

Ruskul Have you set friction to 0 and also built a frame with 0 friction around? It is normal to lose energy when there's friction between objects

TiAm How is it in terms of performance?

Oh, I'm glad to know I'm not the only one who experienced that!

That said, on pc I found the opposite situation:

-(very)Fast simulation with asm.js

-some micro-lags with box2D web.

Thank you for your Reply

Hello!

I noticed that on my android device asm.JS causes some lag, and by lag I mean that sometimes it freezes for something like 0.1 seconds.

Instead, Box2DWeb works perfectly.

Also, I've read about a future Box2DWeb deprecation, but why removing it if it works better than asm.js on mobile?

What are your thoughts?

*Sorry for my english

*The CPU is Snapdragon800

*My app is compiled with Intel XDK

Is this what you want?

I added a pin behaviour to your exhaust so it always follows the rocket, set the gravity to 0 and removed that angle(rocket.x,rocket.y,touch.x,touch.y)+180 because it was useless.

When I told you to use that expression for your game, it was intended for making the rocket escape from you finger.

Here's the .capx [attachment=0:14nk5wda]

Just apply force at a specified angle when you touch the screen.

Angle(Rocket.X,Rocket.Y,Touch.X,Touch.Y) for moving rocket toward touch input

Angle(Rocket.X,Rocket.Y,Touch.X,Touch.Y)+180 for moving rocket in opposite direction from touch input.

Tomorrow I'll be home and if this doesn't work for you, I'll try something else

THANK YOU!

I thought that it was possible to save Dictionary's instance variables too but i was wrong, your .capx made me understand that dictionary can save Keys but not instance variables so i got around it, adapted it to my game and now it WORKS!

Tomorrow I'll be home ready for testing it! I hope it will make my day

Oh, it seems that everything is ok, if you add the buttons and test the performance, let us know

TRY THIS:

For Saving:

Use the save action whenever you want

For Loading:

Set the first layout to the one that will load data, and make it load the game on start of layout or go to a specific layout if it fails to load (when there's no save) like this:

[attachment=0:a70fgryn][/attachment:a70fgryn]

Then, it will bring you to the last place you have saved, but we don't want that. So set this condition on every event sheet:

[attachment=1:a70fgryn][/attachment:a70fgryn]

Place that condition everywhere but not in the destination layout (for example Startscreen), or it will loop.

70%??

On mobile I hope!
