使用 GIMP 轻松地设置图片透明度

由 梦想与她 提交于 2020-12-02 22:11:07
使用色键（或绿屏）技巧来设置你电脑游戏中图片的透明度。 不管你是否正在使用 Python 或 Lua 编程一个游戏或一个 APP，你都有可能在你的游戏资源中使用 PNG 图像。PNG 格式图像的一个优点是能够存储一个 alpha 通道 ，这在一个 JPEG 格式的图像中是不可能获得的。alpha 在本质上是不可见的或透明的“颜色”。alpha 是你图像 不可见 的一部分。例如，你要绘制一个甜甜圈，甜甜圈的空洞将使用 alpha 填充，你就可以看到它后面的任何东西。 一个常见的问题是如何找到一幅图像的 alpha 部分。有时你的编程框架，不管它是 Python Arcade 、 Pygame 、LÖVE，或者其它的任何东西都会检测出 alpha 通道，（在适当地调用函数后）将其作为透明处理。这意味着它将不会在 alpha 部分来渲染新的像素，而留下甜甜圈的空洞。100% 是透明的，0% 是不透明的，在功能上起到“不可见”的作用。 有些时候，你的框架与你的图像资源在 alpha 通道的位置上是不一致的（或者，alpha 通道根本就不存在），你在你想要透明度的地方却得到像素。 这篇文章描述了我所知道的最可靠的方法来解决透明度的问题。 色键 在计算机图形学中，有一些有助于确定每一个像素是如何渲染的值。色度Chrominance（或者 chroma），描述一个像素的饱和度或强度

问题 Im making a game that requires knowing how to draw a rectangle in python 3.2. I have checked lot of sources but none show exactly how to do it. Thanks! 回答1: import pygame, sys from pygame.locals import * def main(): pygame.init() DISPLAY=pygame.display.set_mode((500,400),0,32) WHITE=(255,255,255) BLUE=(0,0,255) DISPLAY.fill(WHITE) pygame.draw.rect(DISPLAY,BLUE,(200,150,100,50)) while True: for event in pygame.event.get(): if event.type==QUIT: pygame.quit() sys.exit() pygame.display.update()

Pygame snake velocity too high when the fps above 15 [duplicate]

由 泪湿孤枕 提交于 2020-11-29 11:16:16
问题 This question already has an answer here : Framerate affect the speed of the game (1 answer) Closed last month . I am having a hard time figuring the physics of speed in this snake game I made using pygame. The issue is that as soon as I set the fps to be above 15, the snake's speed increases as well. I know that this has to do with milliseconds etc which I found to work, high fps with slow speed. However at that point, I could not get the X and Y to be correct so that I can eat the apple. I

Problem with Pygame movement acceleration, platformer game [duplicate]

问题 This question already has answers here : Pygame doesn't let me use float for rect.move, but I need it (2 answers) Closed 7 days ago . When i move right using the right key, i accelerate to a max speed. When i release it, i do decelerate to a stop so that is fine. However, when moving left using the left key, and after releasing it, i continue moving at a fixed speed and then come to an abrupt stop after a short while. Any idea what could be wrong with my code? The original code is from http:/
