StarCraft 1.16.1 Modding: Invisible Siege Mode

Shows solution to modding problem discussed here: http://www.staredit.net/topic/18092/unread/#special
The code in the beginning shows how to make this. The exact steps are as follows:
1) modifiy the 'game_hooks.cpp' file from the general-plugin-template-project (I used the version for visual studio 2008, published by UndeadStar on github)
2) Use visual studio (in my case 2008 version), click open project & open the .sln file from the general-plugin-template-project folder
3) Press the green arrow to "Debug" --> his creates the folders Debug/patch in the general-plugin-template-project folders
4) in these new folders, you should find a .grp file
5) Use Firegraft to make a (new) mod, under the 'Plugin' tab, select 'Add', and then select & add the new .grp file.
6) Save the Firegraft mod, click the resulting Firegraft-File, and in the pop-up window, find your StarCraft exe to start the game with the mod.
