Someone just rocked me with a step function. I'm intrigued.

That surprised me as well.

After some thinking I came up with min and max. If, for example, I want to change direction after x==4 I can do use

    -1.5(max(x,4)-4)
    
    0    4

          \
           \

Maybe there are more tricks like that?

I am not sure if this is a step function, but I saw someone pretty much do an octagon shape to hit someone. How?

(x+1) * max(0, sign(x)) * (1-max(0, sign(x-1/sqrt(2)))) + (1+1/sqrt(2)) * (1-max(0, sign(x-1/sqrt(2)-1))) * max(0, sign(x-1/sqrt(2))) + (-x+sqrt(2)+2) * max(0, sign(x-1/sqrt(2)-1)) * (1-max(0, sign(x-sqrt(2)-1)))
