Gold Mine trigger

I just wanted to know to to correctly trigger goldmines, i wanted a goldmine for 1g/min, 2g/min, and 1g/15 seconds

I have no idea what you are trying to say here, like how you get gold before income or what? Idk o.0

Get a hero, find wherever the vamp is, whatever it kills items come out take it as fast as you can and sell it and you get gold and then you can start basing!

Its actually a pretty simple trigger, you just have to create a new trigger and choose the income trigger then you just set the Income and the requirements.
while setting the Income trigger it will ask you, when he is supposed to give gold. then u can simply set the time in seconds (for example 120.0 for income every 2 minutes)
As requirements you need to set the Building, which is supposed to work as goldmine

May not be 100% accurate because its out of the mind, but thats basically it.

Can you put picture i don't really understand looking to much hard without any screenshot :O
