Buildings giving money

[LoryGundevil]

Hello.
I was trying to make something that makes a building gives money during time like +10 gold every 10seconds OR something like +50 gold every Day Cicle.
For the first i tried using the Haunted Gold Mine Ability but it didn't work (i just edited the ability), for the second i don't really know how to do so, because i didn't find anything usefull in triggers. I never used triggers before, all i've done with them is Special Effects.
Can anyone help me with this thing please? maybe with explaination so i can start to learn something about triggers or script.

this has been asked a lot, check these:
Building income
building=income?
Income by buildings
Building that gives income

i think the last one is closest to what you are looking for
