it did not work for me

[householdscientist]

@Yanagi225 , Thanks , i got it ! : )

[Yanagi225]

@householdscientist 1-- is basically i = i - 1

And i++ is i = i + 1

It's just easier to do ++/-- rather than typing it out.

@WhiteBeltAcademy I think ellipse maybe easier, coz just need define the centre point and the size....? maybe other is the same logic as triangle.

[householdscientist]

i'm quite happy that i understand most of it . but could you please explain me the meaning of

" 1- - " and ""1 ++", i still didn't got it as i'm very stupid in math. thanks !

[WhiteBeltAcademy]

How would you get the same effect with ellipse?

[sharpezor]

noStroke();

triangle(ax,ay,bx,by,cx,cy);

for(int i=triangle_scale; i>=0; i=i-3)

@Shockszzbyyous first of all, sorry for my bad english!

it's because the value of ax dosn't change. if ax=centerx-i; would be in the for-loop the triangle would turn to the left and to the right with ax=centerx+i;. try it out.

hope this helps you

@Shockszzbyyous same question here!!!

[Shockszzbyyous]

why is ax=centerx; not in the loop?
