Checking if engine has been destroyed

[guyfawkestom 60]

Good Morning to all of you,

After a year without touching Arma2 I decided to come back to mission making. I surprised myself by being able to understand and write little pieces of script...

Anyway, I wanted to recreate objectives of the mission PMC05 elimination where you have to destroy engine block of armoured vehicle.

--------------------------------------------------------------------------EDIT--------------------------------------------------------------------------------

But after searching all over the forums, I did not find an answer.

Thanks to this topic : http://forums.bistudio.com/showthread.php?111384-fired-eventhandler-count-how-many-rounds-fired and [FRL]Myke, I managed to write a completely functional script for as mush vehicle as needed

In the init line of the vehicle :

0 = [this] execVM "scripts\chkmotEH.sqf" // adapt the path that you want

chkmotEH.sqf

private ["_unitsht"];
_unitsht = _this select 0; // Target vehicle - init line : 0 = [this] execVM "scripts\chkmotEH.sqf";
_unitsht setVariable ["ShotsTaken", 0]; // unit (vehicle) variablespace to store the required variables
if (isnil "gf_dmgcnt") then {
	gf_dmgcnt = { // stting up of the fonction related to handle damage, that will handle the number of hits.
private ["_unitsht","_loc","_dmgval","_shooter","_ammun"];
_unitsht = _this select 0;
_loc = _this select 1;
_dmgval = _this select 2;
_shooter = _this select 3;
_ammun = _this select 4;
if ((_loc == "motor") and // required target selection
	(_dmgval > 0.02) and  // damage value for direct hit
	(_ammun == "B_127x99_Ball_noTracer" )) // type of ammo to damage
										then { 
_unitsht setVariable ["ShotsTaken", (_unitsht getVariable "ShotsTaken") + 1];
//hint format ["%1", (_unitsht getVariable "ShotsTaken")];// hint the value of the hit stored in Shotstaken
												 if ((_unitsht getVariable "ShotsTaken") == 6) // 3 or 4 shots to call the script fx
																then 	{
		0=[_unitsht] execVM "[b]scripts\chkmotfx.sqf[/b]"; // script fx in an external script for allowing sleep, adapt the path that you want of course
																		};
												 };
				};
						};
gf_chkmotEH = _unitsht addEventHandler ["handledamage", {_this call gf_dmgcnt}]; // finally the EH setup
exit

chkmotfx.sqf

private ["_unitsht2"];
_unitsht2 = _this select 0;
hint "motor has been destroyed";
_unitsht2 setFuel 0;
_unitsht2 lock true;
_gfLogic = "logic" createvehiclelocal (getposASL _unitsht2);
_gfLogic attachTo [_unitsht2, [0,-2,0], "motor"]; 
0 = [_gfLogic,0.75,750,false,false] spawn BIS_Effects_Burn;
sleep 2;
{unassignVehicle _x} foreach crew _unitsht2;
crew _unitsht2 allowGetIn false;
{_x action ["eject", _unitsht2]} foreach crew _unitsht2;
{_x allowfleeing 1} foreach crew _unitsht2;
{_x setdamage 0.5} foreach crew _unitsht2;
{removeallweapons _x} foreach crew _unitsht2;
//{[_x,(getPos _unitsht2),100] call gf_fnc_flee} foreach crew _unitsht2;// to do
exit

With these scripts, once the M107 ammo has hit 3 or 4 times the engine block (selection name : "motor" in brdm-2), chkmotfx.sqf is triggered, smoke starts on the engine block, crew is disembarking, injured, and should flee.

Works at least in SP, I don't play MP. But feel free to tell me.

The problem of Handledamage EH is that it returns two events, for indirect and direct hit, if I caught well. So the trick was to segregate each of them. Fortunately it is more easy than segregating protain from yeast extract, so I asked also for damage value condition, making sure that only the direct Hit was used to increase the hitcount.

I'm sure there is a better way to to that, but it seem to fulfill my requirements. However, if some of you knows how to do a clean script, I'll be very eager to learn proper coding.

Thank you for your help, :)

The script has been updated, but I'd like to have any comments that could optimize the code....

Thanks,

Sounds interesting, I will try this next week after my holidays :)

Hello,

I'll be glad to here any advice on that. This script is SP oriented, so I'm not sure that it will work for MP. But I'm happy to obtain such a result. Let me know if you like it.
