Radio waves animation

How do construct 2 could create a wave animation similar to the next image?

I've tried with this project:

dropbox.com/s/v3ni0y0gnvlcmrp/waves.capx

But it just draws it, not animate a flowing displacement of that waves.

How to solve it?

Wow, newt!

That was impressive. But actually what i'm trying to do is to draw these waves in a canvas because I have to change the degree values of the arc.

It is possible to make the animation you did in a canvas?

Check out this project:

dropbox.com/s/v3ni0y0gnvlcmrp/waves.capx

it fills the canvas, but no animation at all. Hummm...I've employed the timer wait 1 second before drawing the next arc, but it doesn't seems to work. I'm thrilled...

Thanks in advance for any help!

Updated my original to use canvas.

Let's see...

This is awesome, Newt! I'm going to study the code and try to turn it into an automated behaviour, without need of mouse click.

I'm sending you the results!

Great!

That's it, now it should be able to start automatically the animation at an appropiate rhytm so that there are several waves moving away from the border at the same pace, one each 0.25 seconds.

Now it's starting to work. I have two new questions, nevertheless, for you:

�How to implement in construct a loop that allows to create new waves always that the radius reach certain value?

And

�How it is posible that the variable values are soo high from the begginig? I have had to divide them by 100 to make them useful!

for first question: spawn every X*dt

Remember it's a wave drawn into a canvas

I've uploaded a fairly self-explictive project showing my aim.

As you can see when is executed, there is a wave advancing through the canva's white space.

I'm trying to generate several waves so that I can simulate light in an schematic way.

My objective too, is to make those waves to disappear on crushing with the red sprite. This is not easy for me, due to everything is happening inside this canvas.

Have a look on the advances made on the project. I think it's quite interesting for making tutorials afterwards:
