How do I draw a line with multiple Points?

[amstrdm]

I want to write a animate that doesn't just go from one point to the other in a straight way but goes RIGHT then UP and then RIGHT again. I found ConvexHull which should make this possible but I'm wondering if there's any better way?

what do you mean by "write a animate"?

Do you just want to draw a line with a corner? Or do you want to MoveAlongPath along that line?

I suggest you come over to Discord because it's much easier to have a conversation over there...

class rightupright(Scene):
    def construct(self):
        line = VMobject().set_points_as_corners([ORIGIN, RIGHT, RIGHT+UP, RIGHT+UP+RIGHT])
        self.play(Create(line))
        dot = Dot(point=line.get_start())
        self.add(dot)
        self.play(MoveAlongPath(dot,line), run_time=3)
        self.wait()

Thanks a lot for the reply. Sorry the formatting and phrasing was a bit messed up, I was in a hurry.

Yes thank you that's very helpful do you think there's any way to "round" the corners? I guess one way is to somehow add arcs to the corner maybe? Again I'm just wondering if there's a better way to do this. Thanks again for showing the vmobject option I wasn't aware you could use it like that.

Again I strongly suggest you come over to Discord!

class rightupright(Scene):
    def construct(self):
        line = VMobject().set_points_smoothly(
            [ORIGIN, RIGHT, RIGHT+UP, RIGHT+UP+RIGHT]
        )

        self.play(Create(line))
        dot = Dot(point=line.get_start())
        self.add(dot)
        self.play(MoveAlongPath(dot,line), run_time=3)
        self.wait()
