Let's say I want to allow players use a certain cmd every 4th map. If this command is used, there will be shown a poll (e.g. Are you happy? #Yes #No). If > playesr choose Yes a map will change to de_morehappymap. After that map I want to disable players using the cmd which shows up a poll, they are allowed to use that cmd only after 3 maps have passed since that de_morehappymap. How can I hook how many maps have passed since some certain map?
