two ways
there is 2 ways you can make hero get money when they creep, but it depends on what you mean by creeps, do you mean in a regular melee map or in a somthing like a tower defence. if you mean in a regular melee map then you find the creep under the object editor click unit tab, neutrual hostile, click on the creep that you have placed on ur map, scroll down on his properties till you find somthin called gold bounty award, fill them in. There is three different one because it works like having dice so if you want a creep to just give 100 gold then ljust fill in the one just put 100 leave the other two at 0.
or
If you ment for like a tower defence or a dota or somthin then you want to go under trigger editor start a new trigger make it look like this:
event - elapsed game time is 2 seconds
condition -
action - player - turn gives bounty on for player "that the creeps are on"
then you have to give that unit the bounty amount you want like i said in the other one.
