How to put IED's on the road hidden, and how to create a basic infantry ambush?

Coolinator · November 8, 2014

i want to add an ambush scene in my mission, but i don't know how to do it :(

How to put IED's on the road hidden, and how to create a basic infantry ambush?(that also works well when playing in dedicated server).

when i put the code it says: "missing )"?

Sorry try it minus the "bomb=":

"M_Mo_82mm_AT_LG" createVehicle (getPos thisTrigger);

---------- Post added at 05:44 ---------- Previous post was at 04:07 ----------

Just some fun for the ambush group.

In the trigger's onAct after the IED created vehicle:

nul = [thisTrigger, 50] execVM "ambushGroup.sqf";

In the ambushGroup.sqf file:

_area = (_this select 0);
_distance = (_this select 1);
_center = createCenter EAST;

_rndConfig = ["OIA_InfTeam", "OIA_InfSquad", "OIA_InfTeam_AT"] call BIS_fnc_selectRandom;

_pos = [(getPos _area), _distance, random(359)] call BIS_fnc_relPos;

_grp = [_pos, _center, (configfile >> "CfgGroups" >> "East" >> "OPF_F" >> "Infantry" >> (_rndConfig))] call BIS_fnc_spawnGroup;

[_grp, (getPos _area)] call BIS_fnc_taskAttack;

It will spawn a random group of a fireteam (4 men), squad (8, if I remember correctly), or an AT team (4 men), in a relative defined distance away from the trigger (exampled as 50m), in a random direction in relation to the trigger (ambush could come from any direction), they will then attack the trigger position (where the IED went off).

Thanks!! i actually just found a tutorial on how to make ambush and ieds on youtube. Still thanks for your help, really appreciate it :)

I will try ur method sounds so cool!!! by the way does this ambush works in dedicated server?

I just tested it works!!! really cool!!! but i haven't tested it in dedicated server yet.

There isn't a reason for it not too, unless I'm just too tired atm to see any possible issues with that :p.

add "&& isServer" to the condition on the triggers or you will have a lot of bombs and a lot of ambush groups. Assuming that it's a MP mission since you mentioned dedicated.

ooo thank you!! i didnt know about that!! Quick question, do i still need to add "&& isServer" for a trigger i made that grouped with a truck?

For example When the truck goes into the trigger the mission will end. So do i still need to put "&& isServer" in the condition because i play my mission on dedicated server? or it doesn't really matter i can just use "this"?

cuel · October 15, 2011

It matters mostly when you're creating stuff.

Ending the mission has local effect, so no. Everyone should run that.

An important thing to remember is that when you put down triggers in mission, they are in no sense "global" or synchronized on every machine.

Every trigger will exist locally on every machine, and conditions can be true on one machine but no the other. For example using

player in thisList

Would only be true on the machine where the player object is inside the trigger.

You know, I thought the same right after I went to bed :p.

Yea I made that mistake with a mortar script that I made up for an operation for my old unit months back, started with ~400 objects on the map (editor placed), after that script ran there were more than 3000 objects (by the time it became unplayable), all of which were being created on each of the clients (which was 25+), it got ugly fast, lol.

Is there a way i can increase the number opfor units? i wanna use this as enemy reinforments :)

Call line:

nul = [thisTrigger, 50, 5] execVM "ambushGroup.sqf";

_area = (_this select 0); 
_distance = (_this select 1); 
_numGrps = (_this select 2);
_center = createCenter EAST; 


for "_i" from 0 to (_numGrps) step 1 do {

_rndConfig = ["OIA_InfTeam", "OIA_InfSquad", "OIA_InfTeam_AT"] call BIS_fnc_selectRandom;

[_grp, (getPos _area)] call BIS_fnc_taskAttack;
};

Third parameter in call line is now the number of groups you want to come in, it randomizes the group each time, and still randomizes the position they spawn each time (take it out of the for loop if you don't want that), then are tasked to attack the central position.

Hey Jshock, I'm loving your script :) it's really fun using it as enemy reinforcements and ambush :) but how do I add vehicles? Like heli,tanks, ifrits? Not on random though, I don't want to spawn 3 Helis, 5 tanks at same time,you know what I mean? I just want to spawn 1 for each type of vehicle? Or at least can control how many to spawn like a parameter?

Well, do you want to spawn each vehicle in a group on the same position, or just spawn "x" number of defined vehicles in random positions around the center position?

kinda of both lol :) but either way is fine :) Edited December 1, 2014 by Coolinator

By the way quick question, What do i put in parameter, if u want no helis to spawn? do i put 0, or do leave it blank like nothing at all?

So if i dont want heli to spawn i put this?

nul = [thisTrigger, 50, 5, 0, 2, 2] execVM "ambushGroup.sqf";[

or

nul = [thisTrigger, 50, 5, 2, 2] execVM "ambushGroup.sqf";[

Yep, just input 0, that's what the if statements are for.

And just to help you understand why the above won't work, as soon as you remove an argument from the script call the indicies of the arguments (see below) will be off by one, and leave the last argument undefined, therefore, leaving you with a broken script.

//for example, taking out the "number of tanks" argument from the script call
//call line: nul = [thisTrigger, 50, 5, 2, 2] execVM "ambushGroup.sqf";
_area = (_this select 0);   // = thisTrigger
_distance = (_this select 1);   // = 50
_numGrps = (_this select 2);  // = 5
_numTanks = (_this select 3); // = 2
_numHelis = (_this select 4); // = 2
_numIfrits = (_this select 5); //will be undefined

Reading through the BIKI page on ARRAYS, may help you understand this concept.

       [_grp, (getPos _area)] call BIS_fnc_taskAttack;  
   };   
}; 

if (_numTanks > 0) then  
{ 
   for "_a" from 0 to (_numTanks) step 1 do 
   { 
       _pos = [(getPos _area), _distance, random(359)] call BIS_fnc_relPos; 
       _veh = [_pos,0,"O_MBT_02_cannon_F",_center] call BIS_fnc_spawnVehicle; 
       [_veh, (getPos _area)] call BIS_fnc_taskAttack; 
   }; 
}; 

if (_numHelis > 0) then  
{ 
   for "_b" from 0 to (_numHelis) step 1 do 
   { 
       _pos = [(getPos _area), _distance, random(359)] call BIS_fnc_relPos; 
       _veh = [_pos,0,"O_Heli_Attack_02_black_F",_center] call BIS_fnc_spawnVehicle; 
       [_veh, (getPos _area)] call BIS_fnc_taskAttack; 
   }; 
}; 

if (_numIfrits > 0) then 
{ 
   for "_c" from 0 to (_numIfrits) step 1 do 
   { 
       _typeVeh = ["O_MRAP_02_hmg_F","O_MRAP_02_gmg_F"] call BIS_fnc_selectRandom; 
       _pos = [(getPos _area), _distance, random(359)] call BIS_fnc_relPos; 
       _veh = [_pos,0,_typeVeh,_center] call BIS_fnc_spawnVehicle; 
       [_veh, (getPos _area)] call BIS_fnc_taskAttack; 
   }; 
};  

if (_numApcs > 0) then  
{ 
   for "_d" from 0 to (_numApcs) step 1 do 
   { 
       _typeVeh = ["O_APC_Tracked_02_cannon_F","O_APC_Wheeled_02_rcws_F"] call BIS_fnc_selectRandom;
_pos = [(getPos _area), _distance, random(359)] call BIS_fnc_relPos; 
       _veh = [_pos,0,_typeVeh,_center] call BIS_fnc_spawnVehicle;
       [_veh, (getPos _area)] call BIS_fnc_taskAttack; 
   }; 
};

did i do it right?

then parameter would be like this:

nul = [thisTrigger, 50, 5, 2, 2, 2, 2] execVM "ambushGroup.sqf";
