Write another function that behaves similarly to (), but uses the former function ( draw_dashed_line) to draw the dashed curve. For more details on how the thickness for edge lines grow, refer to the width notes of the () draw a straight line function. 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. Screen = need to draw sine and cosine waves on a coordinate system exactly like in this picture.
#PYGAME DRAW DASHED LINE CODE#
To try it out for yourself: copy one of the code snippets above and the code below in an empty file, change the name image to the name of the Surface you want to blit and experiment. By voting up you can indicate which examples are most useful and appropriate. (antialiased_lines_closed, RED, True, points) Here are the examples of the python api taken from open source projects. (antialiased_lines, RED, False, points)Īntialiased_lines_closed = pygame.Surface(size) (line, RED, (0, 0), (50, 50)) # Start at topleft and ends at bottomright.
#PYGAME DRAW DASHED LINE DRIVER#
(arc, RED, arc.get_rect(), 0, pi) # 0 to pi is 180° creating a half circle. Pygame Draw Dashed Line Edirol Ua 1x Driver Windows 7 Steel Panthers World At War Mega Campaign Download Game Train Simulator Indonesia Aliens Vs Predator Proper. (ellipse_filled, RED, ellipse.get_rect()) The holes is a unfortunate consequence of pygame's drawing algorithm.Įllipse size = (50, 25) # Minimize it's height so it doesn't look like a circle. (circle_filled, RED, (radius, radius), radius) (circle, RED, (radius, radius), radius, 10) # Position is the center of the circle. Example drawing a line (gamewindow, (255,0,0), (100, 100), (300, 200), 5) Here we draw a red line from (100, 100) to (300, 200) with a thickness of 5. Points = # The corner points of the polygon. (rect_filled, RED, rect_filled.get_rect()) (rect_border, RED, rect_border.get_rect(), 10) # Draw on it. Rect_border = pygame.Surface(size) # Create a Surface to draw on. The parameters of each function is explained down below at Parameters. The black color is the Surface default color and represents the part of the Surface that hasn't been drawn onto. To draw a filled antialiased shape, first use the antialiased (aa) version of the function, and then use the filled (filled) version. We'll initialize pygame and define some constants before the examples. The functions rectangle() and box() will accept any (x, y, w, h) sequence for their rect argument, though pygame.Rect pygame object for storing rectangular coordinates instances are preferred. The code below will showcase all the different functions, how they are used and how they look. It is also possible to create a custom dashed line see: import matplotlib.pyplot as plt x 1,10 y 3,6 dashes 5,2,10,5 5 points on, 2 off, 3 on, 1 off l, plt. All functions takes a Surface to draw on, a color and a position argument that's either a pygame Rect or a 2-element integer/float sequence (the will only take integers because of undefined reasons). It's convenient to define color constants in advance, making your code more readable and more beautiful. To use the module you first need to import and initialize pygame correctly and set a mode for the display. Functionĭraw a connected sequence of antialiased lines
Pygame has a module, pygame.draw, that contains functions which can draw shapes directly to a Surface.
