Step 13: Now we will use the stored speed information to set the fireworks moving!
- In GRAPHICS, from drag out Set x Speed indented inside the loop.
- Change sprite to p. Change 5 to speed_values[0].
- Your code should look like this: p.set_x_speed(speed_values[0])
- This uses the first stored number that we calculated to set the horizonal speed of each particle!

def return_trajectory(speed, angle):
radians = math.radians(angle)
x_velocity = speed * math.cos(radians)
y_velocity = speed * math.sin(radians)
return (x_velocity, y_velocity)
stage.set_background_color("black")
amount = 10
speed = 5
color_list = ["purple", "yellow", "red"]
stage.disable_all_walls()
def click():
x = stage.click_x()
y = stage.click_y()
particle_list = []
for color in color_list:
for counter in range(amount):
sprite = codesters.Circle(x, y, 10, color)
particle_list.append(sprite)
angle = 0
for count, p in enumerate(particle_list):
count += 1
speed_values = return_trajectory(speed, angle)
# add other actions...
stage.event_click(click)
