Step 12: We have given you new code! This code uses trigonometry to calculate the x and y speed for each particle.

  • From drag out Call Parameters Into Variable. This calculates and stores the x and y speed for each particle.
  • Change my_function(my_parameter1, my_parameter2) to return_trajectory(speed, angle)
  • Change my_var to speed_values. Now speed_values is storing 2 numbers. We will use those next!

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 # add other actions... stage.event_click(click)
