Question

#python oop referencing attributes in objects
# problem is the angle function in my class.
import random
class people():

def __init__(self,x,y,size_of_other_team):
self.x=x
self.y=y
self.target = random.randint(0,size_of_other_team) # choose a random guy from other team

def angle(self, other_teams_x, other_teams_y): # get angle between this guy and his target
dx = other_teams_x[self.target]-self.x
dy = other_teams_y[self.target]-self.y
theta = math.atan(dy/dx)
return(theta)

def move(self):
self.x+=1

red_guys = 10
blue_guys = 10
red_x=[]
red_y=[]
red=[] # objects list
for i in range(red_guys):
red_x.append(random.randint(0,100))
red_y.append(random.randint(0,100))
red_person = people(red_x[i],red_y[i],blue_guys)
red.append(red_person)

blue_x=[]
blue_y=[]
blue=[] # object list
for i in range (blue_guys):
blue_x.append(random.randint(0,100))
blue_y.append(random.randint(0,100))
blue_person = people(blue_x[i],blue_y[i],red_guys)
blue.append(blue_person)

a=0
while a < 9999:
for i in red:
i.move()
print(i.angle(blue.x,blue,y)) ## i want to get the angle between each red guy and his chosen blue target
## problem is here blue.x doesnt work like i want.
#i want blue.x to = ALL blue x's
## DO NOT USE THE BLUE_X LIST. i want to reference x and y from the objects

Answer 1

You can change the code to something like this

Earlier

print(i.angle(blue.x, blue.y))

My suggestion,

print(i.angle([x for b.x in blue],[y for b.y in blue]))

Here blue is a list of people object. angle requires list as argument.

So we give list like mentioned above.

Hope this is what you require.

Regards.
