Thanks, solved

How do I anchor in middle of screen or relative (like 10% left of center)?

Actually I solve this problem with many ways, but I was curious about why "Trigger Once While True" was not working. Tnx Roccinio, forget about System Cond doesn't pick instances and Yes Guizmus, function solve all problems. Tnx all.

Ok, simple question. There is a Object, lets call it "Box", and I have some instances of this object.

When a boolean variable of the box change, I need there something happen with the box that have his variable changed.

I tryed

"|For each box            |

|Box Variable is true    | ------   Box Y set to 1000

|Trigger once while true |"

dont work, trigger once for the first instance and repeat infinite times for other objects.

"|Box Variable is true    | ------   Box Y set to 1000

|Trigger once while true |

dont work too, same effect above.

I had heard that the order of the conditions changes its effect, but I had tested for a long while and nothing happens. Tnx and sorry my english.

Ok, I'm question cause when my project was running at 10 fps (problems with scale rate), the "Every 1 second" conditions delayed so much.

I know that in Every Tick, dt will be 1 second.

But how use Every second condition or Wait X seconds action as Frame Independence?

Somebody tested with CocoonJS laucher and hit 60 FPS? Cause even the examples that come with the laucher are running at 30 fps.

Is a Tablet Sony, android 4.0. There is some objects (3-4 in screen same time) with physics, but they initial settings are immovable, only work when the character interact with them. The default FPS is 40, even if he dont move.

I'm using CocoonJS laucher. I tested a template (sprite example in the CocoonJS) and this runs too at 40 fps. Somebody use this launcher too? I'm sure that is not my device, it runs any game from the market perfectly.    

(Thanks all of you for the help. Before begin using the forum, I read every material in this site, but I'm a little late with my project, so sorry the bothering)

Sorry, I was not clear. The game I was testing is not a Tower defense, but a platform game for mobile using CocoonJS. But when I realised that +20 sprites on screen slow the performance, I wonder if it is possible to make a Tower Defense for Mobile, with so many enemies and towers firing same time (in last stages, for example) using the Construct 2 + CocoonJS.

I read the info about performance in this site and I wonder if this happens because the conversion from javascript to other language is the problem.

It is possible to make a good tower defense game on Construc 2? I'm testing a game using CocoonJS and the FPS low if is some objects in the screen. I think that is impossible to make a Kingdom Rush without lose some performance. (sorry my english)

Thank you! But how it save the game? It is safe? And the Effects are created by the community?

Hello, I'm new in this awesome tool and I can't find answers.

1?) What is the best way to save info in mobile game? I read that local storage can be cheated if the player change the file.

2?) Where find more effects to add and how install it?

(sorry my english...)
