Phaser Box2d Draw or Update points

[NistorCristian]

Hi,

I want to make a Box2d Sof body. I made something like that but I don't know if I'm using the right method. As you can see in the attached image there is a circle and some smaller circles to define the Soft body area. To make it purple I'm using graphics.

    graphics.clear();
    graphics.beginFill(0xFF33ff);
    graphics.drawPolygon(polygonStructure);
    graphics.endFill();

That is what I put in update function. polygonStructure is an array made with position x and y of every little circle.

What is better, to update the points of a polygon and put a graphic sprite over it or draw it like I'm doing it now?

And ... How can I do the edges more soft? Using some arc or something?

 

Thank you
