I don't really understand the explanations V has given in the script can you explain it fully for me?
In a way, that is also the problem behind your request in the first post...
Relationships do not automatically develop, you as the game developer have to tell the game what happens to change any relationship.
Since the relationship system can only be created by scripts, those commands to change the relationship also have to be programmed in using script calls and possibly notetags.
That is what the description in the script is about: it tells you what script calls to use in order to change relationships during your game.
Unfortunately something like this can't be told in a step-by-step manual, because no one knows what types of relationships exist in your game.
Before we can help you understand the commands, we need to know exactly what kind of relationship you want to create first, and where in the description you have problems understanding when you try to create that relationship.
If you tell us that, then we can help you...
