Why are some of my circles disappearing and some not?

The Point of the game is to make all the circles disappear when they Collide but for some reason some circles aren't disappearing? - Thank you for your help in advance!

Collision checking function/Method

Uses the Pythgorean Theorem to measure the distance between two objects def isCollision(t1, t2):#t1 = turtle1 t2 = turtle also when a

function starts with "is" isCollision most likely it will be a Boolean of True or False a = t1.xcor()-t2.xcor()# xcor = Right -xcor = Left/ when they collide the xcor is 0 b = t1.ycor()-t2.ycor()# ycor = Right -ycor = Left/ when they collide the ycor is 0 distance = math.sqrt((a ** 2) + (b ** 2))

if distance < 30:
    return True
else:
    return False

Create class instances player = Player()# after creating a class must make an instances to call it in other words make an Object of the

class border = Border()#sub class

goal = Goal()#sub class

Draw our border border.draw_border()

create multiple goals goals = []#Creating a list of goals for count in range(6):#We are making the code repeat 6 times

goals.append(Goal())#each time the code runs it puts a goal the end 6 times

Set keyboard bindings ms.listen() ms.onkey(player.turnleft, "Left") ms.onkey(player.turnright, "Right") ms.onkey(player.increasespeed,

"Up")

speed game up ms.tracer(0.1)

main loop while True:

ms.update()
player.move()# these two are class methods
#goal.move()# the reason we copyed like we said is cause it's gunna have the exact same movements as our player!
# we want the goal to be True to in our while loop in order for the code to be excuted
for goal in goals:
    goal.move()   # Basically saying If there is a collision between the player and goal we the want the goal to "jump" / Function

in our while True loop if isCollision(player, goal): goal.jump()# baiscally saying if the goal collide's move or "jump" to other location

time.sleep(0.005)
