[英]PyGame Invalid Position For Blit
I am creating a small level designer in Python (using PyGame).我正在用 Python 创建一个小型关卡设计师(使用 PyGame)。 The program is supposed to just let you place down an image, change between images, export to a PNG file, and export image path and coordinates to where it was place in a text document.
该程序应该只是让您放置图像,在图像之间切换,导出为 PNG 文件,并将图像路径和坐标导出到文本文档中的位置。 I have gotten all of these components to work, but I am stuck with one last component, and that is reading the text document back into PyGame, and re-placing all of the images in the correct places with the correct sprites.
我已经让所有这些组件都可以工作了,但我仍然坚持使用最后一个组件,那就是将文本文档读回 PyGame,并使用正确的精灵将所有图像重新放置在正确的位置。
The way that I have it currently (Which has been rewritten and Almost works ) produces an error whenever I try to read from one of my exported files.每当我尝试从导出的文件之一读取时,我目前拥有它的方式(已被重写并且几乎可以正常工作)会产生错误。
The error of course is:错误当然是:
stamped_surface.blit(image, (xcrds, ycrds))
TypeError: invalid destination position for blit
Here is my code:这是我的代码:

This program has a file system and certain controls to make things happen, so here they are:这个程序有一个文件系统和某些控制来使事情发生,所以它们是:
ESC KEY - Auto Exports Program For Reference And Quits Program ESC KEY - 自动导出程序供参考并退出程序
S Key - Saves Surface as PNG file. S 键 - 将 Surface 保存为 PNG 文件。
N Key - Prompts User to select new sprite to use N 键 - 提示用户选择要使用的新精灵
E Key - Exports Image To PNG with file prompt E 键 - 使用文件提示将图像导出为 PNG
O Key - Opens File With Coordinate data and image path data. O 键 - 打开带有坐标数据和图像路径数据的文件。

A Few things you should know: This program auto-saves every file position to the file that contains Coords and Image Paths.您应该知道的几件事: 该程序会自动将每个文件位置保存到包含坐标和图像路径的文件中。
The file system is relatively simple to work out by looking at the code, but if you need some assistance, please ask.通过查看代码,文件系统相对简单,但如果您需要一些帮助,请询问。
blits((source, dest, area), ...)) -> (Rect, ...) you are missing out the destination. blits((source, dest, area), ...)) -> (Rect, ...) 你错过了目的地。 Read here

And if you are making use of coordinates then use square brackets [x-co,y-co] like this:如果您使用坐标,则使用方括号 [x-co,y-co] 如下:
block.blit(image,[0,0])
