unfortunately there is no direct way of giving a player money like that.
However the closest alternative would be to make a Loaded Truck come to a certain point and then self destruct. Then if you set it so that loaded trucks drop crates they will drop a crate which you can make it to always be money in the crate if you edit the crate rules on your map.
I would go into more depth and show the code but I don't have enough time as of right now.

if you need to see what i mean for sure then check my Cliff's of Asvetia map as it has trucks that come by every so often that you can destroy and I had edited the crate rules so that only a few things happen and some of those happen more often.
