Disable penetration of bullets/shrapnel plywood

[Fr3eMan 16]

HI all!
I'm working on a script to create a kill house, and I want to use the plywood panels of editor for create the area, and I don't want allow the bullets to pass the panels, but also if I set it as:

_pos = [_pos1,_pos2,_pos3,_pos4,_pos5];
{
    _veh = createVehicle ["Land_Shoot_House_Wall_F", _x, [], 0, "CAN_COLLIDE"];
    _veh allowDamage false;
    _veh enableSimulation false;
    _veh setDir 14.5;
}foreach _pos;

The bullets can anyway pass it and can hit the objects/unit on the other side, any suggestion?

Might be doable.

Using a hit or hitpart eventhandler on the object, hitpart EH would even return the surfaceType.

Maybe multiplicating the number of objects (may be a performance killer). Or adding invisible walls. (They may be too thick)

I try with this but dasn't work properly:

_veh addEventHandler ["HitPart", {deleteVehicle (_this select 2);}];

Try creating them as simple objects instead of vehicles, maybe.

I tried, doesn't work, create as:

_simpleVeh = createSimpleObject [_model, _position]

[Grumpy Old Man 3545]

Be more specific, what doesn't work?

Creation?

Bullet penetration?

 

Cheers

[killzone_kid 1330]

He is right, simple object retains penetration properties. Trying to stop bullet on "HitPart" also doesn't work, seems like it fires a bit too late. Changing object material is also a no go. So basically last resort - make a mod and alter object properties as you like.

In every way I try to create the object/vehicle "Land_Shoot_House_Wall_F" (plywood panels) is unable to stop the bullet/shrapnel penetration

 

 

So basically last resort - make a mod and alter object properties as you like.

 

Unfortunately, looks like the only solution...

[Guest]

Did you try to stack x objects on the same pos

[Fr3eMan 16]

Did you try to stack x objects on the same pos

 

Yes, don't work anyway.

If only we could overwrite / create new configs directly in the mission...

[b3lx 161]

So if one is to create a config for these walls to make them bulletproof what properties should be changed?

[johnnyboy 3793]

This doesn't answers b3lx's question, but another possibility for original posted problem is to add an onFired eventhandlers to units in kill house that detects the bullet and reduces the velocity by 5X or 10X.   You could also replace the projectile with a spawned SDAR projectile which is the weakest I know of.  My theory that a small enough projectile with a low velocity might not penetrate.  Someone would have to experiment with it.

 

Killhouses should be short range situations, so reduced velocity is unlikely to be noticed by players.

 

UPDATE:  I remembered "solving" this issue for my JBOY Beanbag Shotgun script.  I would replace fired projectile with SDAR bullet, and reduce its velocity and attach visible bandage object to represent the bean bag.  Originally I had problems with "bean bag" penetrating car windows and thin walls, and used this code to solve it.   In this code I have stripped out all the bean bag related code, and only kept the bullet replacement and reduced velocity parts.

_shooter addEventHandler 
["fired",
    {
        _shooter = _this select 0;
            _bulletType = _this select 4;
            _projectile = nearestObject [_this select 0, _bulletType];
             _bullet = "B_556x45_dual" createVehicle [0,0,1];  // using weak sdar underwater bullet for beanbag hit
            _pos = _projectile modelToWorld [0,0,0]; 
            _dir = getdir _projectile;
            _vel = velocity _projectile;
            _vdir = vectorDir _projectile;
            _vup = vectorUp _projectile;
            _velModelSpace = velocityModelSpace _projectile;
            _projectile setpos [0,0,0];
			// ****************************************************
			// Tweak this _bulletSpeed value until you don't get penetration on thin walls,
			// but hopefully keep the value high enough so player doesn't notice bullet drop in short range.
			// ****************************************************
			_bulletSpeed = 30;
            _velModelSpace = [_velModelSpace select 0, _bulletSpeed, _velModelSpace select 2];
            _bullet setdir _dir;
            _bullet setVectorDirAndUp [_vdir,_vup];
            _bullet setpos _pos;
            _bullet setVelocityModelSpace _velModelSpace;
    }
