How much?

ObNoDamageChain blocks this damage, but that is all it says about it.

I wanted to have a central object with smoke effects etc, but no hit taking, with a cluster of child objects to take the hits, trigger functions, and PASS DAMAGE ON TO THE PARENT.

Is the amount tiny, or do they not pass on damage to an object that lacks an inertia box? If I have to have the central object taking damage too, then I lose the effect I am trying to achieve.

in the effects object:

(obFunc (oilSmoke1 (obSmokeTrail (smkDensity .2 smkDiameter 1.5 smkOrigin -2,-1,0 smkLifetiime 0)))) (obFunc (oilSmoke2 (obSmokeTrail (smkDensity .4 smkDiameter 1.5 smkOrigin -2,-1,0 smkLifetime 0)))) (obFunc (oilSmoke3 (obSmokeTrail (smkDensity .6 smkDiameter 1.5 smkOrigin -2,-1,0 smkFire smkLifetime 0))))

in the object to take the hits:

(obDamage (obHits 10 obKillDelay 1 onDmg 2 (obExec (Name 'Lexhaust Func 'oilSmoke1)) onDmg 4 (obExec (Name 'Lexhaust Func 'oilSmoke2)) onDmg 8 (obExec (Name 'Lexhaust Func 'oilSmoke3)) onDmg 10 (obExec (Name 'engine1 Func 'EngKill)))) (plus ( phyRelDensity 0.250000 phyBoxInertia 3.800000,2.200000,0.800000 phyCG 0.000000,0.000000,0.000000 ))

Hope it helps you out Tail

In effect the OP doc is probaby more accurate now, especially the damage chain stuff.

One flaw with the crew radius concept is unarmoured seats taking hits though the rear of the fuselage. A crew radius big enough to emcompass this would also get damage from the inner wings, probably not good.

When I get time I am going to see If I can implent some kind of dodgy penatration thing, i.e the Model has a "toughness" property, and when it gets hit by a bullet, it may slow it down, but potentially not stop it. This will allow it to hit objects that are currently "Protected" by other lods.

Plus it may also allow for some interesting things with fabric bits that offer little resitance to pass the bullet with out contributing much to the damage of the whole LOD. Anything behind it would be in for a rude shock though

The damage passed to the parent is a small fraction...damage * 0.0042 was quoted by Elric.

If this is right, doing 50 hits to the child to destroy it passes up 50*0.0042 which is 0.21 hits....

5 cylinders with total destruction is about 1 hit...which would explain why I never saw the test smoke trail. The central motor had 50 hits, so 5 hits were needed to hit lvl 1 and trigger smoke.

If this is the case, I would need a motor with 9 cylinders of 30 hits each, and a central motor of 1 hit. Assuming the game actually notices fractions, and that all the damage doesn't have to happen in one go...

Is this right?

So, to put it simply.. we can't put enough damage through the chain to affect the parent engine.

So if the number .0042 is correct, each time you shoot the child in slew mode it passes 4 * .0042 = .0168 damage up to the parent. If you set the parent obHits to 1 it would take 1/.0168 = 60 hits to the child to equal one true hit to the parent.

It would seem that if the parent was set to obHits 1 and onDmg 1, that would mean it would only need 1/10th or 6 hits to reach onDmg 1.

I set up something similar, and got no joy. My big worry is in the fractions. If the game doesn't register small fractions, or if the damage passed up isn't cumulative....

If you pass up 0.1 pts each time, it may be that it is only counting whole numbers. If you hit it with something big enough to do 40 pts in one hit, then perhaps it wouldpass up enough damage to notice. This would be fine for Flak, but a little tricky for .50's.

I set up a b17 engine with 10 hits, 5 child objects with 50 hits each, and progressively shot the heel out of each child object with twin .50's. Blew all the child objects away. Base model was set to show smoke at DM1, so 1 hit should have done it. 250 hits to child objects later, and no smoke. 1 burst into the parent and it was toast.....

Either the vlaue Elric quoted is wrong, out interpretation of the effects are wrong, or the game is not doing what it should with the damage!

The 0.0045 value is the global damage modifier. This is used to scale the hit energy in Joules, into a value in the units of obHits. the damage modifier is always applied.

This was the thing I fixed. basically there were area where the damage modifier was being applied twice (i.e. 0.0045 * 0.0045 = 0.00002) this has the effect that the objects taking damge through this path would not get much damage at all. One of these paths was the damage chain, others may (or may not) have included the path that network damage went.

Damage passed up the damage chain is hardcoded. if the object is setup to not accept dammage 100% of the damage is passed to the parent, other wise only 30% is (as well as the original object taking the full 100%)

Some other areas that act a little like damage chains, but aren't are two methods of applying damage to crew. One is the Crew Radius. This means that is a object takes some damage, the crew positions are checked to see if the hit point is in the dfined crew radius. if so from memory 20% of the damage is passed to the crew position. This is also anothe rarea where the double damage modifier was being applied incorrectly, and hence crew are killed much easier now.

Also there is another point, which sounds a little sus to me, that every crew position takes 50% of any damage to the root object.

I hope that clears that up
