sinking trawlers and attaching explosives.. help required (muppet)

Recommended Posts

hi there im half way through an underwater mission where the objective is to steal some sdv's, sneak into a harbour and then blow up 4 trawlers (mine layers in disguise, dastardly opfor trick!!)

how ever I cant attach anything to the trawlers or the ground underneath them (underwater)

also

the buggers don't seam to take damage! ive used everything I can think of and nothing is denting the boats

does anybody out there have any idea how to resolve these issues??

sinkable ships and underwater satchel placement? (what's the point of being an underwater demo expert if you cant do underwater demo!?)

any help is greatly appreciated

thanks in advance

There was a video I saw recently of a trawler listing to one side and everything falling off and sinking you will have to search for it. It was very well done. Here is my ghetto fabulous version:

COB_BOAT enableSimulation false;

_count = 0;
while {true} do {
_count = _count - 0.1;
COB_BOAT setPos [(getPos COB_BOAT select 0),(getPos COB_BOAT select 1),_count];
       if ((position COB_BOAT select 2) < -20) exitWith {true};
sleep 1;
};

Huh. A day of scratching my head with setVectorDirAndUp loops, and now I learn from the video that all you need in Arma 3 to sink the trawler is something on these lines:

trawler1 [url=https://community.bistudio.com/wiki/setCenterOfMass]setCenterOfMass[/url] [[-1.8, -6.5, -4.5], 60];
trawler1 [url=https://community.bistudio.com/wiki/setMass]setMass[/url] [5000000, 60];

That's pretty handy. I made a more complicated script which tries to account for faster sinking after the water reaches the deck. Also has some options for customisation. I'm not perfectly happy with it, but maybe someone finds it useful, or can suggest improvements / tweak it:

/*
Script for sinking a trawler. Save as sinkship.sqf or whatever you prefer.

Call with:
[shipname, sinkside (optional), seconds to sink (optional), smoke TRUE/FALSE (optional)] execVM "sinkship.sqf";

Or simply:
shipname execVM "sinkship.sqf"

Possible sinksides: "LEFT", "RIGHT", "LEFT FRONT", "RIGHT FRONT", "LEFT BACK", "RIGHT BACK", "RANDOM"
If sinking time is 0, it will be randomised between 60 seconds and 180 seconds
On default the sinkside is "LEFT BACK", sinking time 2 minutes, smoke emitter TRUE.

Example:
_null = [trawler1, "LEFT FRONT", 90] execVM "sinkship.sqf";
*/

// Declare private variables
private ["_ship", "_sinktime", "_sinkside", "_smokeloc", "_smoke_e", "_smoke", "_x", "_y", "_z", "_x1", "_y1", "_x2", "_y2", "_x3", "_y3", "_z1", "_z2", "_z3"];


// Fetch and validate the parameters
_ship     = [_this, 0, objNull]      call BIS_fnc_param;
_sinkside = [_this, 1, "LEFT BACK"]  call BIS_fnc_param;
_sinktime = [_this, 2, 120]          call BIS_fnc_param;

// Although it would be nice to implement damage to multiple locations, not today

// If _sinktime is 0, randomise the time between 1-3 minutes.
if (_sinktime == 0) then { _sinktime = 60 + random 120 };

if (_relativedir >= 95  && _relativedir <= 139) then { _sinkside = "RIGHT";       _attachpos = [ 4.42, -2, -6]; _uy =  1 };
if (_relativedir <= 228 && _relativedir >= 185) then { _sinkside = "LEFT BACK";   _attachpos = [-4.75, -9, -6]; _uy = -1 };
if (_relativedir >= 140 && _relativedir <= 186) then { _sinkside = "RIGHT BACK";  _attachpos = [ 4.42, -9, -6]; _uy =  1 };

_democharge = "DemoCharge_Remote_Ammo_Scripted" createVehicle getPosATL _target;

_democharge attachTo [_target, _attachpos];
_democharge setVectorDirAndUp [[0, 1, 0], [_uy, 1, 0]];

sleep 120;

if (!isNull _democharge) then
{
	_democharge setDamage 1;
	sleep 1;

	// only call for the client where the ship is local

This is incredible, never thought something like this could be possible.

I wonder if BI will ever focus on implementing physx for soldiers and smaller objects or improve the current implementation, seeing what's possible in the current state wants you beg for more.

This is fantastic work. If there was a way to find out where the damage occurred you could sink the ship from that side. So if a missile impacts on the trawlers front, the front sinks etc. Not sure how easy it is to get that information.

This should be easy to implement with BIS_fnc_relativeDirTo

Just scan for a placed satchel, call the function with the satchel and trawler as parameters and you got the relative direction where the satchel was placed.

That's pretty cool! Will totally use that sometime!

Ooh, that's why the function in the bomb planting script was returning weird stuff, I used BIS_fnc_dirTo by accident. D: Fixed it now. Thanks, everyone.

how did you call the script for placing the charge on the side of the boat?

yeah that's awesome. thanks for making that script. very cool. works great on other boats too.

How can the attach script be modified to destroy a boat? I'm trying to destroy a csat HMG boat, even with the boat set to critical damage, but the blast wont destroy it.

Any chance of using that exploding barrel script to get the demo charge to be amplified?

_barrel = _this select 0;
if (isServer) then {


           _ex = createVehicle [
               "Bo_Mk82",
               _barrel modeltoworld [0,0,1],
               [],
               0,
               "CAN_COLLIDE"
           ];
           _ex setVectorDirAndUp [[0,0,1],[0,-1,0]];
           _ex setVelocity [0,0,-1000];
          deleteVehicle _barrel;

};  

I tried to change _barrel to _boat, but it didnt do anything different.

this addEventHandler ["HandleDamage",{if ((_this select 4 ) in ["DemoCharge_Remote_Ammo"] ) then {_this execvm  "boom.sqf"}}];

I put that EH on the boat to call the boom.sqf with _boat instead of _barrel, hoping the demo charge would activate the script but it didnt blow up how I hoped.

Really? :Oo: I'd have thought that the increase in mass at the beginning would sink any other ship like a rock right away. ...actually I guess that's an appropriate sinking speed for any other vessel the game has. However, that addAction script attaches the explosive based on the size of the trawler, so there's a floating explosive somewhere nearby. You could maybe put the location setup of the latter under an if so it'll attach to the default [0, 0, 0] when it's not a trawler:

private ["_target", "_unit", "_id", "_magaz", "_sinkside", "_attachpos", "_uy", "_relativedir", "_democharge"];

_target = _this select 0;
_unit   = _this select 1;
_id     = _this select 2;
_magaz  = magazines _unit;

if(!("DemoCharge_Remote_Mag" in _magaz)) then { hint "You have no charges to place"; }

else

{

hint "Bomb planted with a two minute timer."; 
_unit removeMagazine "DemoCharge_Remote_Mag";

_target removeAction _id;

_relativedir = [_target, _unit] call BIS_fnc_relativeDirTo;

_sinkside = "RANDOM";
_attachpos = [0, 0, 0];
_uy        = -1;

if (_target isKindOf "C_Boat_Civil_04_F") then
{
	if (_relativedir <= 359 && _relativedir >= 274) then {
		_sinkside = "LEFT FRONT";  _attachpos = [-4.42,  8, -6]; _uy = -1
	}; 
	if (_relativedir >= 0   && _relativedir <= 94)  then {
		_sinkside = "RIGHT FRONT"; _attachpos = [ 4.42,  8, -6]; _uy =  1
	};

	};
};

_democharge = "DemoCharge_Remote_Ammo_Scripted" createVehicle getPosATL _target;

_democharge attachTo [_target, _attachpos];
_democharge setVectorDirAndUp [[0, 1, 0], [_uy, 1, 0]];

sleep 120;

if (!isNull _democharge) then
{
	_democharge setDamage 1;
	sleep 1;

	// only call for the client where the ship is local
	// maybe put this under an if as well?
	[[[_target, _sinkside], { [_this select 0, _this select 1] execVM "sinkship.sqf" } ], "BIS_fnc_spawn", _target] spawn BIS_fnc_MP;
}

};

How can the attach script be modified to destroy a boat? I'm trying to destroy a csat HMG boat, even with the boat set to critical damage, but the blast wont destroy it.

Edit: Maybe it was because of it attaching a long way off the boat in the way I mentioned above? If not, you could just put _target setDamage 1; after the last sleep.

it does sink it rather quick, but it does sink like the trawler does, usually back end down first the times i tried it. Only thing is once it's at the bottom, the waves cause them to go nuts.

Guys,

do you think is possible to create a Tutorial to how to do these stuff?

I didn't find anything usefull about Sinking boats in Arma 3 on line.

Especially for noobs like me.

Thanks,

Tapparella

Great to see, is it considered !alive once sunk in terms of trigger conditions?

Hi there,

script is awesome in SP, but having some problems with MP execution.

I have this script here

_smAttachMine = getMarkerPos "smAttachMineTwo";
drugShip = "C_Boat_Civil_04_F" createVehicle _smAttachMine;

I'm using the following for the addAction

_attachCharge = [[drugShip,["Place Explosive Charge",{[drugShip,player,0] execVM "scripts\attach_charge.sqf"}]],"addAction",true,true,false] call BIS_fnc_MP;

my problem is the error message shows drugShip as undefined for the pass through to the execVM.

If I define as a publicVariable like below, the adddAction doesn't execute attach_charge.

_smAttachMine = getMarkerPos "smAttachMineTwo";
drugShip = "C_Boat_Civil_04_F" createVehicle _smAttachMine;

Any thoughts?

Great Script and thanks to everyone for contributing. 

 

I do have one problem with it in that it doesn't appear to work on a dedicated server environment. The status of the ship changes to !alive, that part is fine, all the sexy animations of it sinking are missing. 

 

I've attached a video showing the issues - skip to 3:00 to see the charges go off;

Any suggestions?

Hello, sorry for  coment on this old post. I was trying to make the trawler sink to a charge explosion, using Magirot sripts, but there is not attachtTo.sqf scrip availabe, so  I tried with EoV script:

/*

EtV_ChargeCheck =

};
//=======================
EtVInitialized = true;

I  put this addActionthis addAction ["Place Explosive Charge", "EtV.sqf"];on the trawler object's init. . I couldnt make it work.  Please i someone could check what I m doing wrong, I will be gratefull.

I made it!!!!!!  

I used sabotage.sqf by Malak

Spoiler

_object = _this select 0;
player playMove "advepercmstpsnonwrfldnon_putdown";

sleep 15;
_timeleft = 20;

while {true} do {

// 5 minutes counter
hintsilent format ["Charge Explode in :%1", [((_timeleft)/60)+.01,"HH:MM"] call bis_fnc_timetostring];

if (_timeleft < 1) exitWith{};
  _timeleft = _timeleft -1;
sleep 1;


};
"M_Mo_82mm_AT" createvehicle getpos _object;
{_x setdamage 1} foreach crew _object + [_object];

Now the problem is that  it seems that player has unlimited charges,  like if doesn t take in account soldier inventary ,  beside there s no charge animation as in the next video:

This is the first time that I made a scripting thing work, I knew, I didn´t write a line of code, but still,  I m very happy!
If someone could help me whit this issues, thanks in advance.

EDIT: More!!! I solved it...Magirot addaction is Attach_Charge.sqf. Now works like a charm...Tried MP and works too!

If anyone want to try, here{s the sample mission:
