Write another function that behaves similarly to (), but uses the former function ( draw_dashed_line) to draw the dashed curve. Start = (int(prev_line_len) // step) * stepĮnd = (int(prev_line_len + dist) // step + 1) * stepįor i in range(start, end, dash_length*2):Į = min(start - prev_line_len + dash_length, dist) Distribute the strokes along the line: def draw_dashed_line(surf, color, p1, p2, prev_line_len, dash_length=8): Compute the Euclidean distance between the points and the Unit vector that points from the beginning of the line segment to its end. The function has an additional argument prev_line_len which indicates where the line segment is within a consecutive curve. Write a function that operates similar as () but draws a dashed straight line. (surf, color, start.get(), end.get(), width) Start = origin + (slope * index * dash_length)Įnd = origin + (slope * (index + 1) * dash_length) # get back values in original tuple formatĭef draw_dashed_line(surf, color, start_pos, end_pos, width=1, dash_length=4):įor index in range(0, int(length/dash_length), 2): Return int(math.sqrt(self.x**2 + self.y**2)) Return Point((self.x/scalar, self.y/scalar)) Return Point((self.x*scalar, self.y*scalar)) Return Point((self.x - other.x, self.y - other.y)) Return Point((self.x + other.x, self.y + other.y)) I have smth similar to what I need, but how can I make it curved? Or how can I improve this to make it like, not ? import pygame I did all the work well except I failed to represent dashed and curved line with pygame. I need to draw sine and cosine waves on a coordinate system exactly like in this picture. rect ( screen, BLUE, ( start, size ), 1 ) pygame. fill ( GRAY ) for rect in rect_list : pygame. pos size = end - start, end - start screen. type = MOUSEMOTION and drawing : end = event. append ( rect ) drawing = False elif event. pos size = end - start, end - start rect = pygame. pos size = 0, 0 drawing = True elif event. type = QUIT : running = False elif event. set_mode (( 640, 240 )) start = ( 0, 0 ) size = ( 0, 0 ) drawing = False rect_list = running = True while running : for event in pygame. """Place multiple rectangles with the mouse.""" import pygame from pygame.locals import * RED = ( 255, 0, 0 ) BLUE = ( 0, 0, 255 ) GRAY = ( 127, 127, 127 ) pygame.
