在MS Paint上编写绘画程序 - 如何在鼠标移动事件之间进行插值？

import pygame

pygame.init()

screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption("Interpolation Example")

running = True
previous_mouse_position = None
current_mouse_position = None

def lerp(a, b, t):
    return a + (b - a) * t

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.MOUSEMOTION:
            previous_mouse_position = current_mouse_position
            current_mouse_position = event.pos

    if previous_mouse_position and current_mouse_position:
        for t in range(1, 100):
            lerp_x = lerp(previous_mouse_position[0], current_mouse_position[0], t / 100)
            lerp_y = lerp(previous_mouse_position[1], current_mouse_position[1], t / 100)
            pygame.draw.circle(screen, (255, 255, 255), (int(lerp_x), int(lerp_y)), 1)

    pygame.display.flip()

pygame.quit()
