Notes

1. I do not provide support for listen/local servers but the plugin should still work properly on them.
2. I will not help you with installing or troubleshooting problems on your part.
3. If you get errors from SourceMod itself, that is your problem, not mine.
4. MAKE SURE YOU MEET ALL THE REQUIREMENTS AND FOLLOW THE INSTALLATION GUIDE PROPERLY.

Questions You May Have

If you have any questions that aren't addressed below, feel free to message me or post on this thread.

1. How do I enable/disable the plugin in certain game modes?

You must specify the game modes in the nff_enabledgamemodes and nff_disabledgamemodes convars.

Here are some scenarios and their outcomes:

• Scenario 1

nff_gamemodetypes "0" // The plugin is enabled in all game mode types.
nff_enabledgamemodes "" // The plugin is enabled in all game modes.
nff_disabledgamemodes "coop" // The plugin is disabled in "coop" mode.

Outcome: The plugin works in every game mode except "coop" mode.

• Scenario 2

nff_gamemodetypes "1" // The plugin is enabled in every Campaign-based game mode.
nff_enabledgamemodes "coop" // The plugin is enabled in only "coop" mode.
nff_disabledgamemodes "" // The plugin is not disabled in any game modes.

Outcome: The plugin works only in "coop" mode.

• Scenario 3

nff_gamemodetypes "5" // The plugin is enabled in every Campaign-based and Survival-based game mode.
nff_enabledgamemodes "coop,versus" // The plugin is enabled in only "coop" and "versus" mode.
nff_disabledgamemodes "coop" // The plugin is disabled in "coop" mode.

Outcome: The plugin works only in "coop" mode.
