Need Example To Make Own Script

Hi guys, I want to build my own script but unfortunately, I'm a total noob. I already made a thread but the info wasn't enough:(
Here's what I want to ask for examples:
Using only "1.png","2.png","3.png" and "click" until stopped by user,
but
If "A.png" or "B.png" appear,
then (1) look for "5.png" at region 1,
if "5.png" is found then "click",
then "waitMultiExist" {"6.png","7.png","8.png"},
if "6.png" still appear
then repeat "waitClick"{"7.png","8.png"},
if not
then check region 2 for 5 seconds,
if "A.png"or "B.png" still appear then repeat from (1),
if "5.png" is not found but found "9.png"
then click "10.png" at region 3.
Then continue clicking "1.png","2.png","3.png" like normal,
if "11.png" is found after clicking "3.png"
then do the following:
click "11.png" then click "12.png"
if not repeat from the start (infinite loop)
