Source Mod Installers

^{Extra thanks to User:Garry Newman for relaying the basics of a mod installer.}

For this, you need NSIS and HM NIS Edit.

Use the following code where:

• ##MODNAME## is the Mod name.
• ##MODVERSION## is the installer's release version.
• ##MODTEAM## is the Mod's team.
• ##MODURL## is the Mod's website.
• ##MODDIR## is the Mod's root directory (i.e. cstrike).
• ##INSTICO## is the location on the local computer where the icon for the installer executable is.
• ##DESKICO## is the location on the local computer where the icon for the desktop icon for the game is.
• ##FILE1## is the first file you wish to install in the mod folder.
• ##FILE2## is the second file you wish to install in the mod folder.
• ##FILEX## is the last file you wish to install in the mod folder.

Note:To automate the FILE1-FILEX list, use the NSIS Script Wizard in HM NIS Edit, then copy the list to your setup.nsi.

Note:You might want to be sure to include a ZIP-compressed version of the mod as a download. This will make certain people who do not like third-party setup files will be able to get the mod.

Code from setup.nsi
