APASRI TITATARN : Bots n Plots class
First touch with Python . . . .gettin to know how to draw basic shapes
Here is my first drawing in class with coding.
my sheep robot. . . funny one
My Aim about this class :
" I would like to make imageBot and furthur step would be to make it move as short animated GIF"
Homework 2nd week Assignment to make your own moving robot.
This is my CloudBot. A cloud with falling snowflakes GIF. I coded in processing with python language. Here is the code . . .
Code----
#cloud
width = 400
posx = [width/4,width/3,3*width/5,width/2,width/5,2*width/3,3.8*width/5,width/2.3]
def setup():
size(400,400)
background(255)
frameRate(12)
def draw():
noStroke()
background(179,226,228)
change= sin(frameCount*0.1)
drawcloud(change)
sx= width/2
n = frameCount
textsnow(posx,change)
saveFrame("cloudbot##.jpg")
def drawcloud(change):
print change
fluffy = change*5
fill(255)
#cloud 1 S
ellipse(1.25*width/5,0.9*height/1.8,80+fluffy,80+fluffy)
#cloud 2 M
ellipse(2*width/5,height/1.8-height/10,130+2*fluffy,120+1.5*fluffy)
#cloud 3 L
ellipse(2.7*width/5,0.95*height/1.8-height/10,120+fluffy,145+fluffy)
#cloud 4 M
ellipse(3.5*width/5,height/1.8-height/10,110+2.5*fluffy,110+2*fluffy)
#face
fill(80)
ellipse(width/3,height/2,7,7)
ellipse(2*width/3,height/2,7,7)
def textsnow(posx,change):
fill(255)
textSize(32)
i=0
while i <7:
text("*",posx[i]+change*i,height/1.8+frameCount*(i+1)/5)
i =i+1

I also made the gif version of Kaleidoscope by make 35 different images each turning 10 degree of the source image.
