auto-move a players focus to center on their token

greetings! I am new to API scripting and am looking for some help. I would like an API script that will move the players focus when their token is moved without moving everyone else's focus, and without moving the GM's focus.  I understand that this should be doable with the ping() command, though getting it to function correctly is eluding me.  I would like to use this as a "slave" to the GM. I am using Roll20 to run my maps on the tv i have laid onto our game table. I have the "player" account running on the tv. I ultimately would like to be able to move the player token as a GM, and the player screen automatically update to be centered on the new location of the token. I also only want it to do so for the player's token. So I don't want it to re-center every time I move an enemy token. is this possible?

I think I figured it out shortly after I posted this. Here is the script I have that is working. I just listed the playerID so it only moves the "map" player. I haven't tested it on different maps yet, though I think it should work similar. My next step will be to make it work for any player so that if I move their character token, their focus automatically follows.  on("change:token",function(obj){         if(obj.get("controlledby")=="-NGILJxHysRtPTUC8ZsQ"){             sendPing(obj.get("left"),obj.get("top"),obj.get("pageid"),"-NGILJxHysRtPTUC8ZsQ",true,"-NGILJxHysRtPTUC8ZsQ");         } });

Here's a script that uses a command to pull all controlling players to a token when used: <a href="https://app.roll20.net/forum/post/7846802/api-to-move-slash-ping-specific-players-not-all-of-them/?pageforid=7846802#post-7846802" rel="nofollow">https://app.roll20.net/forum/post/7846802/api-to-move-slash-ping-specific-players-not-all-of-them/?pageforid=7846802#post-7846802</a> You can probably use it to modify if you want a version that automatically pings when a token is moved.&nbsp;&nbsp;

Ping Buddy is a script that can do all of this and more. It can automatically ping to a given token, a player's own token, follow a token as it moves, and more besides. Demo Video
