Prevent damage building temporarily

[SoloZone 1]

Hi All, I am creating a MP sandbox. I have a SQF that creates 6 Land Towers. Which will be destroyed later once a trigger is satisfied. Below is how I set the towers Handle Damage to indestructible. It works, no issue there.

for [{_x=1},{_x<=_z},{_x=_x+1}] do

{

_tower = createVehicle ["Land_Cargo_Tower_V1_F", getpos start, [], 0, "CAN_COLLIDE"];

_tower addEventHandler ["HandleDamage", {false}];

_tower SetVehicleVarName (towerarray select _y);

_tower call compile format["%1 = _this ; PublicVariable ""%1""",towerarray select _y];

alltowers = alltowers + [_tower];publicvariable "alltowers";

_y=_y+1;

sleep 1;

};

Later in the game I have a player Addaction when they find an object, which allows them to remove the HandleDamage. Well it does that too...in another script tied to the addaction.

_matchtower addEventHandler ["HandleDamage", {_this select 2}];

_matchtower setdamage .75;

Here is where its getting fishy and doesn't work. The building is now @ .75, in the below section I hint the damage and its .75 until I shoot a rocket at the building. Once I hit the building it gets reset to 0 and becomes indestructible again?????

while {alive _matchtower} do

{

_tdamage = getdammage _matchtower;

FOCK_GHint = parseText format ["%1 Damage %2",_matchtower,_tdamage];publicVariable "FOCK_GHint";hint FOCK_GHint;

sleep 1;

};

some background, the first code, only Dedicated is creating the buildings, not sure if this matters.. by thought I'd add.

Any help in my concept would be greatly appreciated.

Ummm, use allowDamage instead of a HandleDamage EH?

[SoloZone 1]

Thanks jshock, tried that and its still the same? I thought I did try that before..

[jshock 513]

So the following idea doesn't work?(psuedo):

_tower allowDamage false;

//some action
_obj addAction ["Allow tower damage",{whateverTower allowDamage true; whateverTower setDamage 0.75;}];

[SoloZone 1]

exactly.. its the weirdest. The only difference is the addaction runs a script. This script determines the tower is nearest to the player and then does the allow damage true; setdamage 0.75

I know the script is kicking off cause the action will reduce the damage to .75 (I hint it to see) and I take a shot at it and it brings it back to 0 and won't allow damage.

you have to cancel damage protection on the same PC you set it

[SoloZone 1]

when I create the towers(6) and assigning allowdamage to false, im using if (!IsServer) exitWith {}; so I am assuming only the Server initiates it. When the player uses the action and it kicks off the script, it too is if (!IsServer) exitWith {}; so only the server would be executing the cancel damage...

I have always struggled with this (ie Server vs dedicated vs local).. so bear with me.

Your script needs to be running on the server for it to be executed on the server. Adding !isServer will not make your client script magically run on the server, it will run on the client until if (!IsServer) exitWith {}; then it will just exit.

allowDamage is remotely executable, so you can use BIS_fnc_MP (to ensure it's ran on the server), so when you create your towers:

fnc_allowDamage =
{
(_this select 0) allowDamage (_this select 1);
};

[[_tower,false],"fnc_allowDamage",false,false,false] call BIS_fnc_MP;

//in action code
[[_tower,true],"fnc_allowDamage",false,false,false] call BIS_fnc_MP;
_tower setDamage 0.75;

Why make function if allowDamage is already supported by remote exec config https://community.bistudio.com/wiki/CfgRemoteExecCommands

[[whateverTower, false], "allowDamage", false] call BIS_fnc_MP; 

is enough.

Ugh, I'm just out of it today, that's what I meant to do, but must have gotten sidetracked in my head while writing this out :p.

Gents. thanks this is working. I understand that the action script is a local event, but adding the BIS_MP and only allowing Server to action the call does it. Wow. Learning everyday. Thanks again.

To answer to your original code problem..

Later in the game I have a player Addaction when they find an object, which allows them to remove the HandleDamage. Well it does that too...in another script tied to the addaction.

_matchtower addEventHandler ["HandleDamage", {_this select 2}];

_matchtower setdamage .75;

You are not removing your HandleDamage EH but instead starting another. You need to use the EH ID passed back from the original to remove it.

example..

{
_tower = createVehicle [ "Land_Cargo_Tower_V1_F", getPosATL start, [], 0, "CAN_COLLIDE"];
_EHID = _tower addEventHandler [ "HandleDamage", { 0 } ];
_tower setVariable [ "EHID", _EHID, true ];
[ _tower, _x ] call BIS_fnc_objectVar;
alltowers pushBack _tower;
}forEach towerarray;
publicVariable "alltowers";


//Switch off
_EHID = _matchtower getVariable "EHID";
_matchtower removeEventHandler [ "HanldeDamage", _EHID ];
_matchtower setdamage .75;
