Map Voting is an unofficial quality of life addon which allows players to vote on the next map.

Because some custom game modes may need to manually change the map due to unique win conditions, Map Voting provides a means of checking when it is loaded and a script to call when wanting to change the map and still abide by the players’ votes.

Checking for Map Voting

Map Voting implements a uniquely named actor called MapVoting_Loaded which allows the standard trick of using the return value of [SpawnForced](<https://zdoom.org/wiki/SpawnForced>) as a means to check for another file being loaded.

This allows us to create a very easy function to return whether or not Map Voting is loaded.

function bool isMapVotingLoaded (void) {
	return SpawnForced("MapVoting_Loaded", 0, 0, 0, 0, 0);
}

Handling Map Voting

In the situation that Map Voting is loaded, a mapvote_changemap script is provided that you can execute in lieu of [Exit_Normal](<https://zdoom.org/wiki/Exit_Normal>) or ConsoleCommand("nextmap"). Below is an example of how these pieces together may all look in a script called by Rage Roboenza when one team wins and the round is over.

function bool isMapVotingLoaded (void) {
	return SpawnForced("MapVoting_Loaded", 0, 0, 0, 0, 0);
}

script "ragerobo_roundend" (void) {
	if(isMapVotingLoaded()) {
		ACS_NamedExecuteWithResult("mapvote_changemap");
	} else {
		Exit_Normal(0);
	}
}
