ellipse(ax,centery,cx,by);

xD

[powerwingman]

it did not work for me

[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 !

[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.

[householdscientist]

@Yanagi225 , Thanks , i got it ! : )

How would you get the same effect with ellipse?

[householdscientist]

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

[sharpezor]

noStroke();

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

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

[Shockszzbyyous]

why is ax=centerx; not in the loop?

[TheGamingtoday]

@Shockszzbyyous same question here!!!

[einfachmoe]

@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]

not really like the arduino ide but some syntaxes are the same :)

[LIGEN5]

really great turtorial

[best123of]

Can't get this to work. Copy'd everything 1:1 and he doesn't want to take my "i". Keeps telling me that there is no "i". Tried for about half an hour now :<

[0902frank]

really helpful videos well explained. Thanks

[XtremeGamer20]

Really awesome! Except you could try this:

Change the stroke value to (0,0).

This makes it transparent, and the gradient effect looks cooler :)

[XtremeGamer20]

Never mind, I wasn't done watching the video when I commented ^_^

[somebody123321456654]

what does for stand for? why do you need it?

[dreamplanter]

wow, this was realy helpfull, I try to make different sized rectangles move back and forth together (so that it looks like they where unified) and i think with a loop that controles speed through a syntax this should be easy

but if anyone knows a way to gain this effect easier I'ld be grateful :D

[AntiCitizenOne1]

these are really helpful

thank you!
