to install: add the whole atlis_tanding.altis folder from the .rar file into your mission folder, if you are trying to export a mission to multiplayer you have to copy the folder from missions to mpmissions , the arma 3 editor export to mp is broken !) so that it turns blue when you go to select it in multiplayer, also the respawn system wont work if it is not lan multiplayer (the description.ext file with respawn = "base" in missions folder) once you copied the folder to your missions folder example (C:\Users\jg\Documents\Arma 3 - Other Profiles\namus\mpmissions\a53.Altis) in there you need to open altis_landing.altis folder and copy the Init_respawn.sqf and AI_respawn.sqf files from that folder and paste them into your mission folder again where you just placed this folder you extracted, in this example into the a53.altis folder as well as leave them in the altis_landing.altis folder you copied from)
before you copy this mission to a multiplayer mission folder thus turning it into a mpmission, you have to set up the respawns by adding this line into the initialization of any ai unit on the map you placed in the editor and want that unit to respawn!
_nil = [this, 7, 1, "spawnMarker", "operationMarker", "Operation", "start"] execvm "Init_respawn.sqf";
you have to match/edit the "marker" name of the marker with the initialization line you entered into the ai unit you want to respawn, ill just use one marker for endless enemies and leave the default:
spawnmarker
then in the initialization line edit it to match what you labeled the marker where you want the ai's to respawn
in this example it is already spawnmarker
so that's where they will all respawn if you add that line into the intitilization when creating the ai unit in editor
you can change the "operation" with "attack" which is what i did, they don't respawn with same loadout its the default rifleman one if that's what you placed the unit, you can change the number 7 by however many times you want that ai to respawn there at the marker you placed and the number 1 in the line above to however long you want the ai to wait before respawning.
also if anyone knows how to disable smoke grenades tell me
place a marker and call it respawn_west then in description.ext type
respawn = "BASE"; respawndelay = 3; corpseManagerMode = 1; corpseLimit = 1; corpseRemovalMinTime = 1; //seconds corpseRemovalMaxTime = 2; //seconds
this will remove dead bodies and allow the player to respawn (only works when hostin lan mission by copyin mission folder over to mpmissions from missions after savin, you cannot edit it then)
