Is it possible to amend a property value?
I'm trying to rig a spawner that will create a list. Lets say for example people who trigger the spawner. When they trigger it I want to add their name to a list. Can this be done? Can I set the text of a book to be GET + TRIGMOB?
appending to a string is easy. Writing text to a book is harder and would require scripting access to book contents.
In general, to append strings use the string substitution brackets to do something like
SETONTHIS/name/{GETONTHIS,name} {GETONTRIGMOB,name}
since it is just substituting strings before it actually parses the entire entry, you can also do things like
SETONTHIS/name/{GETONTHIS,name} : {GETONTRIGMOB,name}
if you wanted to put colons between the old and new strings, or
SETONTHIS/name/{GETONTHIS,name} ({GETONTRIGMOB,name})
to put the new string in parentheses
