Hello.
I implemented a particle system based on this example. However, some of my particles remain stationary and are not moving. I’ve tried hard to figure out why, but I can’t spot it. Please assist me. My code is here: https://codesandbox.io/p/sandbox/particle-sphere-vn34qs .
It’s not that they’re not moving, they’re just stuck within the boundary constraints you’re defining between lines 218 and 235. You can see it clearly here: JSFiddle.
Thanks @Fennec . Do you have some idea how I can increase the boundary without losing the sharp definition of the sphere. I have tried increasing the boundary but the shape becomes less defined. So I suppose, ideally, the points should be able to move within the sphere but when they hit the surface, they change direction to go back inward.
Ok I’ve managed to fix it. The boundary I was defining is a cube instead of spherical hence the loss in shape. Thanks so much for the help.
