Can you move player using vector3? I don't want Teleport()

how do U move player? I do NOT want to teleport player, i want it to move smoothly from pointA to pointB.
Is there something like Move()?

PHP:

Player::setMotion();

I don't realy know how to use it. Can you demonstrate me?

And what about other entity? Like pig, creeper and stuff.

Right now entity AI is not implemented. So, you can't run a single line of code to tell the entity to move towards that point.

so what should i do?
It will be so great if you give me the code
