即使我定义了名称“delta_scroll”，也没有定义它？

Question

so I am trying to make my enemy not scroll with my camera when it moves left and right

I someone helped me make a function to stop my enemy from scrolling all it suppose to do is not make my enemy scroll example vid

def onscroll(enemying, delta_scroll): 
    for enemys in enemying:
        enemys.position = (enemys.position[0] - delta_scroll, enemys.position[1])

then on my main loop I called that function so my enemy doesnt scroll with my screen

    # camera left and right movement
    if playerman.y < 250:
        playerman.y += 1
        for enemys in enemying:
            enemys.y += delta_scroll

but for some reason I keep getting the same error

name 'delta_scroll' is not defined

Quick tip- there are a TON of pg.image.load("myImg.png") commands. here is a better way of doing it:

standingright = []
for i in range(1, 16):
    imgPath = "d"+str(i)+".png"
    img = pg.image.load(imgPath)
    standingright.append(img)

This is a much more concise way of loading the images. It will result in the exact same list of images in the exact same order, but I thought I would mention it to you because it will make your code much neater.

About the issue at hand: I searched your code for mentions of delta_scroll, and found it being used, but never defined. Also I saw you defined the function "onscroll", but never used it. Are you getting these two mixed up perhaps?
