I am trying to change socials so they can be done even if the char isn't in the room. To do this I want to make two seperate functions, one that checks if the first argument after the social is a player name or if the last argument is a players name, and if that is true to go to the function that handles socials directed to chars, and if neither of them are a players name (or they are blank) then go to the function that handles socials in just one room, but I'm not sure how to get from the bool check_socials to the other functions, so if someone can write just a real brief outline for me how to do it, it would be much appreciated.

You might change the part where it cycles through the people in the room to cycling through all connected players. That might be a simple way of doing it.

Yep, did that, I had to redo the ignore part since it only checked if you were ignoring the people in the room.

Another thing I need is to remove the space at the end of an array, how can I do this?

Not sure what you mean by "space at the end of an array".

OK, I've got char *argument; which contains 'x ' and I want it to only contain x, how would I do it? I'm also wonder how to clear an array, since I am using a for statement to use the same array each time, and it seems to keep whatever was in it previously until I change it, is there any any way to clear it?

Hmmm - you are asking about pointers and it looks like you are not too sure how they work.

One possible way is this:


char * p = "x";


Here is another way:


char * pp;

 pp = malloc (100);  // allocate 100 bytes for the string
 strcpy (pp, "x");   // put "x" in it


Here is how you could "empty" it:


strcpy (pp, "");


However I would not blindly copy this code. Find a book on C and read up on how pointers work.
