sprite

问题 I'm confused why my sprite is not moving while jumping. I've checked several times and changed my code over and over with no luck. My code is below and contains 3 pages, first contain the main loop, second contain the player class and third contain some game functions. Main import pygame from player import Player import game_functions as gf import sys import time def run_game(): # Intialise the game and start the screen pygame.init() screen = pygame.display.set_mode((800, 600)) pygame.display

问题 I am working on a simple game. I created a pygame sprite which and tested it by making it move forward and rotating at a consistent speed. However, it seams to be moving left and up (where sin and cos are negative) quicker than right and down (where sin and cos are positive). I tested it without moving and just rotating and it works. Here is the code: import pygame import sys from math import cos, sin, pi from time import sleep SCREEN_WIDTH = 800 SCREEN_HEIGHT = 800 FPS = 60 pygame.init()

问题 I made a small particles application, but I was testing it and the function at the bottom has to be called "update". I thought the function name, just like variables, was just a name. I thought it didn't matter what it was named, as long as it's the same when you call it. Apparently I was wrong. It will only recognize "update". If I change the function to "move", it will throw an error. Could someone explain why it's like this? import pygame import random pygame.init() win_height=600 win

问题 I am making a game that connects a line between a 2 players. I want to make it so I can tell when an object (which is also a sprite) collides with the line. The way I thought of doing this is creating a line that acts a sprite. The line will be able to change length depending on where the players are. I'm a bit new to PyGame so I'm not too sure on what I have so far: class Line(pygame.sprite.Sprite): def __init__(self): pygame.sprite.Sprite.__init__(self) self.image = pygame.Surface([400,400]

问题 This is just a quick question regarding sprites in PyGame, I have my image loaded as in the code below, and I'm just wondering how to display the sprite in PyGame like drawing a rectangle or circle. I don't want to have it behave in anyway. I think I use a blit command, but I'm not sure and I'm not finding much online. Here's my image code for loading it. Star = pygame.image.load('WhiteStar.png').convert_alpha() You could just provide an outline for loading a sprite. I simply want to display

问题 So basically ive been hoping it would be possible to effectively turn your sprite while moving it around with W A S D . Any ideas because im certainly stumped, thanks! 回答1: See How do I rotate an image around its center using PyGame? for rotating a surface. If you want to rotate an image around a center point ( cx , cy ) you can just do that: rotated_car = pygame.transform.rotate(car, angle) window.blit(rotated_car, rotated_car.get_rect(center = (cx, cy)) Use pygame.math.Vector2 to store the

问题 This question already has answers here : Is it possible to change sprite colours in Pygame? (1 answer) Trying to make sections of sprite change colour, but whole sprite changes instead (1 answer) Closed 17 days ago . I want to change the colour of a rect dynamically during runtime. Currently set_colour is filling all of the pixels of the surface with a single colour value. This works, but an issue arises when a method like set_outline is called, which modifies the transparency of the surface.
