I dont know maybe problem in poorly written manual https://community.bistudio.com/wiki/Arma_3_Respawn https://community.bistudio.com/wiki/BIS_fnc_respawnTickets
I found a lot of similiar themes with no answer how to make BIS_fnc_respawnTickets work for unit not for side.
1 . in init.sqf or in server only script write [nameofunit,3,false] call BIS_fnc_respawnTickets; or try [nameofunit,3] call BIS_fnc_respawnTickets; or [nameofunit,(3,false)] call BIS_fnc_respawnTickets; or try[nameofunit,(3,true)] call BIS_fnc_respawnTickets. Actually i dont know how to do it right becouse there is no explanation in official manual or everywhere on internet how that fucntion works 2. Launch mission, die , respawn ,u still have 3 tickets, die 100 times u still have 3 tickets . I even tried killed eventhandler with [player,-1] call BIS_fnc_respawnTickets. Still no progress.
Oh . i suck again, forget to respawnTemplates[] = {"Tickets","Counter"}; in descriptin. KILL ME PLS
It wasnt a issue. it was my bad. But there is new problem. When u lost all your tickets and reconnect server u still can play. So ticket system dont have sence for separated live system (example: 3 lives perplayable unit)
