问题描述
我正在开发游戏，但是在处理图像时遇到一些问题.我已经加载了一些图像.加载它们并使用screen.blit()如下所示:
I'm working on a game and I have some problems working with images.I have loaded a few images . loading them and using screen.blit() was okay like below:
img1 = pygame.image.load("leaf.png")
img1 = pygame.transform.scale(img1, (25,25))
leaf = img1.get_rect()
leaf.x = random.randint(0, 570)
leaf.y = random.randint(0, 570)
但是我不知道如何在这样的if语句中删除它们:
but I don't know how to remove them in an if statement like this for example:
if count == 1:
...
尽管我可能没有办法，但我应该在图像上绘制一个矩形以使其消失.另外，我不知道如何使用screen.fill()而不希望其他图像消失.还有其他办法吗?
and I though maybe there is no way and I should draw a rectangle on the image to disappear it. Also I don't know how to use screen.fill() while I don't want the other images to get disappeared. Is there any other way?
推荐答案
您可以填充单个图像，因为它们是pygame曲面.
You can fill individual images, since they are pygame Surfaces.
首先，我要做的是在定义叶子的x/y之后将类似的内容放进去:
First, what I would do is I would put something like this after defining the leaf's x/y:
leaf.image = img1
然后，我将创建一个名为transparent的颜色变量:
Then, I would create a color variable called transparent:
transparent = (0, 0, 0, 0)
您可能知道，前3个数字代表RGB颜色值.最后一个数字是颜色的alpha(透明度)值. 0是完全不可见的.
The first 3 numbers, as you might know, represent RGB color values. The last number is the alpha (transparency) value of a color. 0 is completely invisible.
最后，我将添加以下代码以使叶子完全透明:
Finally, I would add this code to make the leaf completely transparent:
leaf.image.fill(transparent)
这将使叶子透明，而不会使窗口中的所有其他图像消失.希望这会有所帮助！
This makes the leaf transparent without making every other image in your window disappear. Hope this helped!
