this is the part im lil confused about to add the extra ball
location=[img.size[0]/2,img.size[1]/2]
speed=[0.,0.]
blobsize=16
xs,ys=img.size[0]-blobsize,img.size[1]-blobsize
acceleration=0.05
friction = 0.993
import time
start_time=time.clock()
n_frames=0
i tried copying but it did nothing do i need to copy it and change something so
the python app dont read the same txt twice and jus do nothing?
also on the txt bellow if i add another bal somehow i dotn have to copy or
change the txt bellow do i? it should create same value for both balls?
x_bounce_factor = .8 * (1 - min(6,abs(sense_conn.delta[0])) / 9)
y_bounce_factor = .8 * (1 - min(6,abs(sense_conn.delta[1])) / 9)
if location[0]>xs:
location[0]=xs-(location[0]-xs)
speed[0]= -x_bounce_factor * speed[0]
speed[1]=0.90*speed[1]
if location[0]<0:
location[0]=-location[0]
speed[0]= -x_bounce_factor * speed[0]
speed[1]=0.90*speed[1]
if location[1]>ys:
location[1]=ys-(location[1]-ys)
speed[0]=0.90*speed[0]
speed[1]= -y_bounce_factor * speed[1]
if location[1]<0:
location[1]=-location[1]
speed[0]=0.90*speed[0]
speed[1]= -y_bounce_factor * speed[1]
im just confused on how to get the programme to add another ball into it and
keep everything the same..
i tried changing and copying some of the script but the app jus loads the whole
ball script twice and seperate ball on each.
also could you link advise any good tuturials that would help me ive read some
on the net but need more help really.
thank you for your time. .
