file_seek

Places the read pointer to a certain position in the file.

var_nsave file_handle;

string test_str;

text test_txt
{
   layer = 25;
   pos_x = 300;
   pos_y = 275;
   font = _a4font;
   string = test_str;
   flags = visible;
}

starter seek_data()
{
   sleep (2);
   file_handle = file_open_read("test.txt"); // test.txt contains lines with these numbers: 0 1 2 3 4 5 6 7 8 9
   file_seek (file_handle, 4, 0); // skip the first 4 bytes from the beginning of the file
   file_str_read (file_handle, test_str); // test_str contains "2" (without the quotes) now
   while (key_space == 0) {wait (1);} // wait until "space" is pressed
   while (key_space == 1) {wait (1);} // wait until "space" is released
   file_seek (file_handle, 8, 1); // skip 8 bytes from the current position ("2")
   file_str_read (file_handle, test_str); // test_str contains "6" (without the quotes) now
   file_close(file_handle);
}

add_buffer

Adds a buffer to the engine file system. If the engine attempts to open a buffered file it will read the data from the buffer instead of loading the file from the hard disk again.

patch

Some drivers display a wrong animation frame when several models with the same mesh, but different animations are visible at the same time. Set patch to 1 or update your nVidia video drivers to get rid of the problem.
