Runescape Script Question

hi, im kinda new to sythe (so if this is in the wrong section please tell me) and i have a question about Runescape Scripts. I use alot of diferent scripts myself and when you look at the script it says something like
NewRSTILE (2300,2100)
I know that those are X Y coordinates and that they refer to ground tiles. But
how do you find the ground tiles while ingame. I've tried looking through actual runescape (www.runescape.com) and that wont help at all. I've tried RS bot
(which i use alot) and Debug Ground, Debug Object ect. it gives me numbers like 2300 but that wouldnt work in a script would it?. I need to know how you can find the X Y coordinates on Runescape with a client...or something idc just as long as it works...Im trying to create a first script...and i wanna first make a script that just starts somewhere and clicks a nearby tile then stops... (just to c if the script works.) IDK how to find the X Y coordinates and all those clue scroll things are degrees and N S E W ect. and those dont help at all...

please help,
