In this example I am creating a function to react when a console command is called, just as you normally do when creating a plugin. In this case, we want to block the "amx_aimwatch" command from being called after 3 times so we return PLUGIN_HANDLED in the blocker plugin. Console commands hit the list of plugins in order as listed in plugins.ini so as long as we place the blocker plugin before the plugin containing the function then we can prevent it from reaching the function plugin.
