Hello Guys! First post here.
I'm working on a project, a game about viruses and the cardio vascular system. Essentially, I'm trying to mimic a current like effect for the blood vessels that push the player and other entities either away to the heart or into the heart.
To illustrate this I have included a very rough graphic to show the idea
Issue is, I don't know how to go about doing this, so I'm hoping one of you know how or can point me in the right direction to do this.
Thanks!
Jordan.
