Collision inside geom

Phaser 3

Is it possible to track the collision inside the geom, and not just outside?

I want to create a circle with a ball inside, and the ball always came out from the circle and than only collide from outside.

Using Arcade Physics or the Geom stuff?

I tried with Arcade Physics in many ways.

What i want to do is to create a ball wich follow the cursor but closure the ball in a circle.

First I tried to create a circle shape geom and place a ball inside, but it didn’t work. after the ball comes outside, it couldnt go inside again.
Second I tried with a graphics circle but this one wasnt work either (not even inside and outside, I red something that the problem might be the size, but i cannot add any size to a graphic gameobjcet)

So I’m right here

I don’t see it happening with Arcade Physics (unless you can create your ‘hollow’ circle out of rectangles or circles). Try Matter, defining your shape with polygons.
