Question

移动部分一直在底部 如何在Python模式下处理图像？我尝试了一切，没有关于PyProcessing的教程。请帮忙我尝试的另一种方式是：如果keyPressed（39）:( 39是右箭头键是ASCII）（然后是什么）

def setup():
    global back, canvash, canvasw, cornerpointx, cornerpointy
    global invader, invaderx, invadery, invaderw, invaderh
    global ship, shipx, shipy, shipw, shiph
    global beam, beamw, beamh

    shipy = 0
    shipx = 0
    canvasw = 800
    canvash = 800
    shipw = 100
    shiph = 100
    shipx = 0
    shipy = 0
    beamw = 50
    beamh = 900
    invaderw = 50
    invaderh = 50
    size( canvasw,canvash )
    back = loadImage( "back.png" )
    ship = loadImage( "ship.png" )
    invader = loadImage( "alien.png" )

def draw():
    global back, canvash, canvasw, cornerpointx, cornerpointy
    global invader, invaderx, invadery, invaderw, invaderh
    global ship, shipx, shipy, shipw, shiph
    global beam, beamw, beamh

    background = image(back, 0, 0, canvasw, canvash)
    image(ship, shipx, shipy, shipw, shiph)
    image(invader, 100, 350, invaderw, invaderh)

def keyPressed():
    global back, canvash, canvasw, cornerpointx, cornerpointy
    global invader, invaderx, invadery, invaderw, invaderh
    global ship, shipx, shipy, shipw, shiph
    global beam, beamw, beamh

    if key == CODED:
        if keyPressed == LEFT:
            shipx = shipx + 10

Answer 1

要检测箭头键，您必须检查keyCode，而不是keyPressed，所以试试这个：

if keyCode == LEFT:
    shipx = shipx + 10

此外，我不知道您是否需要执行这些步骤，但对于我的测试，if key == CODED不是必需的，我必须将setup()中的变量声明移到顶部该程序（对于图像，首先将它们设置为无，然后在loadImage()中调用setup()）
