Vitaly Semenov in pro.lua

он перезаписывает файл каждый раз. А в файле не 7, потому что почему-то последний раз не сохраняется. Может close добавить?

Кто может помочь? Я изучаю raycast и псевдо трехмерное изображение, картинку из лучей я построил, а как мне выделить к примеру ребро стены?

Отпиши в личку, мимо писал псевдо3д движок

your code is not working as you want, because you dont understand how io.open works. Please, read the documentation.

In most programming languages functions for open files working same way.

lua io.open == php fopen, for example

print & write different results

1. Here different open methods: "w", "r", "a", "w+", "a+", "wb", "ab+" etc, all are different. Read about it.
2. File is the byte stream, that should be open, read/writed and C L O S E D. Read about bufferization and flush.
