This macro is a little more difficult to use than the previous ones, so you need to carefully familiarize yourself with its functionality.

This macro is based on a double click: in the Perfect World game, if you double-click on a character from your party, all your twins will start following him. It is important to note that if you are using the game version 1.6.2 or later, your twins will follow you even while flying and raise their altitude according to the leader of the group. However, if you have version 1.5.5 or older, this option will not be available — the twins will simply follow the ground. In this case, it is recommended to first take to the air and set the desired height, and only then activate the macro.

After logging into the game, set up all the game windows so that the icons of the party participants are located in the same areas on each window. Then, first of all, click on the character who is at the top of your group's list, as he will always be your leader.

To activate the following, double-click on the leader of the group, and your twins will immediately start moving towards him.

When setting up the macro button, choose the one that is convenient for you. Personally, I use the V button for this purpose. 

Don't forget to check the version and follow the instructions to achieve the best results.
