file_text_open_read

This function opens the text file with the indicated filename for reading only, returning the unique id of the file that which should be stored in a variable as it will be used for all further actions to do with that file.

In the case of an error, the function will return -1. However, in some cases where the file could not be loaded (like an invalid filename being passed), the function may still return a file ID, in which case the return value of the file closing function will be false.

NOTE You can only have a maximum of 32 files open at any one time. You should also always close files when finished as this writes the information and frees the memory associated with the file.

语法:

file_text_open_read(fname);

返回:

Text File ID or -1

例子:

file = file_text_open_read(working_directory + "level.txt");

这将从与游戏相同的目录中打开“level.txt”，并将文件 ID 存储在变量“ file”中。
