spawning a group with a trigger

[craptakular 1]

I have been watching this video series to teach me how to spawn units and groups based on a trigger.

This works in the editor but in his videos he says this won't work for multiplayer? :confused:

I have the following script that I call via the trigger andf it works, but will it work in MP? IF not, where do I read to make it work?

//////////////////////////////////////////////////////////////////

//Groups can be found here: http://community.bistudio.com/wiki/Ambient_Combat_Manager_-_Group_types
//The script below spawns a single group and tells them to follow a single waypoint.

_TakGroup1 = [(getMarkerPos "spawnpoint1"), EAST, (ConfigFIle >> "CfgGroups" >> "EAST" >>"BIS_TK" >> "Infantry" >> "TK_InfantrySquad")] call BIS_fnc_spawnGroup;

_wp1 = _TakGroup1 addWaypoint [(getmarkerpos "wp1a"), 0];
_wp1 setwaypointtype "MOVE";
_wp1 setwaypointstatements ["True", ""];

_wp2 = _TakGroup1 addWaypoint [(getmarkerpos "wp1b"), 0];
_wp2 setwaypointtype "MOVE";
_wp2 setwaypointstatements ["True", ""];

_wp3 = _TakGroup1 addWaypoint [(getmarkerpos "wp1c"), 0];
_wp3 setwaypointtype "SAD";
_wp3 setwaypointstatements ["True", ""];

Secondly, is it possible to minimise the amount of code and have multiple groups use the same waypoints without duplicating 9 lines of code each time?

I have search the forum, I apologies if this question is so stupid but we all started somewhere :D

Well at least your second question is easy to answer: yes, it is possible.

Using a finite array consisting of markernames will allow you to cycle through it with a forEach.

// Example
_markers = ["wp1a", "wp1b", "wp1c"]; // etc...
_waypoints = [];
_currWp = objNull;
_TakGroup1 = [(getMarkerPos "spawnpoint1"), EAST, (ConfigFIle >> "CfgGroups" >> "EAST" >>"BIS_TK" >> "Infantry" >> "TK_InfantrySquad")] call BIS_fnc_spawnGroup; 

{
   _currWp = _TakGroup1 addWaypoint [(getmarkerpos _x), 0];
   _currWp setwaypointtype "MOVE";
   _currWp setwaypointstatements ["True", ""]; 

   _waypoints set [count _waypoints, _currWp];
} forEach _markers;

After the loop is done, all your waypoints references are stored in the _waypoints-array (_wp1 = _waypoints select 0, _wp2 = _waypoints select 1, etc).

Okay the only problem I see here concerning MP is this script would be executed on all clients once the trigger gets activated, spawning several groups.

So you would want to limit this i.e. using a

if (isServer) then {execVM "spawnGroup.sqf";}

in the activation field of your trigger. But it should suffice to wrap the if-statement around the content of the act.-field you already have.

I didn't try it so I don't know if my hunches are correct, so you should test it with a MP mission :D

After reading up a bit more I think this should be the right code for it to work in multiplayer:

//Groups can be found here: http://community.bistudio.com/wiki/Ambient_Combat_Manager_-_Group_types
//The script below spawns a single group and tells them to follow a single waypoint.

if (!isServer) exitwith {};

_TakGroup1 = [(getMarkerPos "spawnpoint1"), EAST, (ConfigFIle >> "CfgGroups" >> "EAST" >>"BIS_TK" >> "Infantry" >> "TK_InfantrySquad")] call BIS_fnc_spawnGroup;

_wp1 = _TakGroup1 addWaypoint [(getmarkerpos "wp1a"), 0];
_wp1 setwaypointtype "MOVE";
_wp1 setwaypointstatements ["True", ""];

_wp2 = _TakGroup1 addWaypoint [(getmarkerpos "wp1b"), 0];
_wp2 setwaypointtype "MOVE";
_wp2 setwaypointstatements ["True", ""];

_wp3 = _TakGroup1 addWaypoint [(getmarkerpos "wp1c"), 0];
_wp3 setwaypointtype "SAD";
_wp3 setwaypointstatements ["True", ""];

Could someone confirm this is now correct?

Look at the lower end of my post, as we are concordant with using the if-statement, it should be alright in MP :)

Thanks matey, I didn't see you post before! doh. I will test it, forgot about Foreach and loops :p
