Ok its been about 2 years for me but could some one refresh me on how to put custom mapping on my server?

You can place mapping within your server with many ways. How-ever simply using an unmanaged system, and simply placing your codes in OnGame / FilterscriptInit is not efficient.

However, mapping is normally loaded with the gamemode / filterscript.

There are some filterscripts that allows you to create custom mapping, although the easiest method is using a map editor.
There are several which you can search for on the internet.

In the basic SAMP Map Construction after placing mapping, you can just click "show code" and add that to your gamemode or a filterscript, prefferably loaded under On(GameMode/FilterScript)Init.
Using "RemoveBuildingForPlayer" code ofcourse cannot be placed there, that should prefferable be in OnPlayerConnect.
