Need some help getting characters to follow each other correctly

[Petr]

In the original version (first from the top), I found out that line 302 does it. The frame synchronization is done by Move_Team. I think that on line 302, the target location will be somehow wrong. It doesn't distinguish where the movement is going and places the frame the same way as line 297 - but line 297 it is used in case the characters are always going in the same direction, if I understand it correctly.
I don't know how you could sharpen 4 directions of movement with a single mathematical determination of the frame in the source image at the end of the _PutImage command on line 302.
