Mesh animation

So Its like this. I wanted to make two spheres collide (something like two worlds colliding) but I ran into a problem. Only the origin point moved. I´m not skilled in animation so any help is good

Once you put them under the control of physics, they don’t care what you tell them to do.

You can create one or more pinned vertices for your cloth. Or you can push them into each other with (possibly invisible) colliders.
