[英]Python - Pygame - circular movement
I´ve the following code: 我有以下代码:
import pygame, sys, math
run = True
white = (255, 255, 255)
black = (0, 0, 0)
angle = 0
size = width, height = 800, 800
screen = pygame.display.set_mode(size)
clock = pygame.time.Clock()
screen.fill(white)
while run:
msElapsed = clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
screen.fill(white)
pygame.draw.circle(screen, black, (int(math.cos(angle) * 100), int(math.sin(angle) * 100)), 10)
pygame.display.flip()
angle += 0.05
pygame.quit()
this creates me a circle, which circles around the coordination (0, 0). 这将创建一个圆圈,该圆圈围绕坐标(0,0)旋转。
i want to move the center from (0, 0) to (100, 100). 我想将中心从(0,0)移至(100,100)。
Thank you in advance 先感谢您
Just add 100 to the x and y coordinates to adjust the center position: 只需在x和y坐标上加上100即可调整中心位置:
x = int(math.cos(angle) * 100) + 100
y = int(math.sin(angle) * 100) + 100
pygame.draw.circle(screen, black, (x, y), 10)
