killed entity reward, have code, need to convert to a function

[ililedie]

have this code that I made by myself but I don't want to repeat so many lines for each type of entity, tried to transform the code into a function but... I suffer from serious skill issue. Can someone give me sample code from this? I need to have as "variables" the random amount of money ex. (random number from 1 and 4) and the type of entity ex. (pig), so that I can call the function on an entity death event like

on death:
  if victim is a pig:
    function reward(pig, 1 and 4)

the code I did is this, working obviously

on death:
  if victim is a pig:
    if damage was caused by void:
      if {author::%victim%} is set:
        set {_1} to a random number between 1 and 4
        add {_1} to balance of "%{author::%victim%}%" parsed as player
        send "%{_1}%" to "%{author::%victim%}%" parsed as player
        clear {author::%victim%}
