清除光标所在的pygame表面的一部分

我的游戏中有一个“你得分高,输入你的名字缩写”屏幕,它有效。然后我决定我想要一个闪烁的光标,其中首字母将是,并且它将从初始的一个(x,y)开始,然后当输入时,移动到初始2(x,y)。问题是,如果你在光标绘制蓝色矩形时按下一个字母,它会将其留在屏幕上,我需要清除该区域。有没有办法做到这一点?这是我的初始输入代码和光标闪烁代码:

def update_highscores(index):

    background.fill(BLACK)

    # co-ords for inital entry

    ix = []

    ix1 = (background.get_width()/2) - 25
    ix2 = ix1 + 20
    ix3 = ix2 + 20

    ix.append(ix1)
    ix.append(ix2)
    ix.append(ix3)

    iy= 140

    inits = []
    initsurf = []

    title = "You have a high score"
    textsurface = write(title)
    background.blit(textsurface, ( (background.get_width()/2) - (textsurface.get_width()/2), 60))

    enterinits = "enter your initials"
    textsurface = write(enterinits)
    background.blit(textsurface, ( (background.get_width()/2) - (textsurface.get_width()/2), 90))

    screen.blit(background, (0, 0))
    pygame.display.flip()

    for c in range(3):
        letter = -1
        while letter == -1:
            blink_cursor(ix[c], iy)
            screen.blit(background, (0, 0))
            pygame.display.flip()
            clock.tick(25)

            letter = getkey()   
            screen.blit(background, (0, 0))
            pygame.display.flip()

        if letter <= 127:
            inits. append(chr(letter))

        elif inkey == K_RETURN:
            break

        initsurf.append(write(inits[c]))
        background.blit(initsurf[c], (ix[c], iy))
        screen.blit(background, (0, 0))
        pygame.display.flip()

    initStr = inits[0] + inits[1] + inits[2]
    highnames[index] = initStr

def blink_cursor(x,y):
    global highcursor
    highcursor +=1
    highcursor = highcursor%11

    if highcursor == 5:
        pygame.draw.rect(background, BLUE, (x, y, 20, 20), 0)
    elif highcursor == 10:
        pygame.draw.rect(background, BLACK, (x, y, 20, 20), 0)

答案 0 :(得分:0)

快速和脏:只需将highcursor设置为9并调用blink_cursor:

if letter <= 127:
        inits.append(chr(letter).upper())
        highcursor = 9
        blink_cursor(ix[c], iy)
        screen.blit(background, (0, 0))
        pygame.display.flip()

当blink_cursor首先将光标计数增加1到10时,当计数为10时,它会绘制一个黑色矩形。排序。
