A little confused with COD4's grenade kill radius

Just how large is the kill radius for COD4? Does 300 damage cover all of the 6.5m radius.. Or is it just the center of the blast, and anything further does 75 damage?

If the latter, just how large is the center of the blast that does 300 damage?


Oh and correct me if I'm wrong but..

WaW's frag grenade does 300 damage in the center of the blast, and farther from that up to 4.4m it does 100 damage.. and after 4.4m it does 10 damage?

P.S. You are my bro, bro.

Goes from 300 down to 75 I think it would be directly proportional.

PS: Welcome and read forum rules.

But how large is the blast kill radius of 300?

PS: Is Den Kirson really serious about the "You are my bro, bro" thing?

[bradqqqqq]

I really dont have 10,036 posts.

I would assume the radius is right where it says "throwback" on it. I may be wrong den might be in the middle of making a mw2 chart.

PS: Yes he is, but you wont be banned or anything for not having it.

Actually I believe the chart means that CoD4 grenads do 300 in the center and 75 damage at 6.5M range. Anything between would presumably be based on the range with damage calculated on a linear slope.

If I'm reading it right you take no damage outside of 6.5M He didn't list the range where the grenade does 100 damage. If it's linear, and my math's right, (both are possibly spotty assumptions) then the CoD4 grenade does 100 damage at about 5.777...M without Sonic Boom. With Sonic Boom the kill radious becomes 6.3555...M, very close to the outer edge and even at the edge damage becomes 93.75.

Then again that's probably rounded up, though I don't know if the rounding step would be done before or after range, I'm sort of assuming that Sonic Boom's multiplier is added last, after range rather than before and that rounding is the final step, but who knows. If the rounding happens before that could alter the kill radius to 6.361209964M (Using a spreadsheet, hence lots of decimal places.)

I'm curious if damage is just based purely on the player's origin or the nearest hitbox kinda think. I suspect the origin, such that if you get behind a corner just enough to put the 'nade out of view then you live, even though your arm and nearly half your body would be in the blast. Most FPS's simplify explosions like that. Either way it's very very close to the edge and if you somehow manage to be in the range to just get hurt you'll be left with only 6 or 7 health.

Anyway, either my math and/or understanding of this could be wrong so...

I think the kill radius is a little bigger than the throw back radius in both MW's. Otherwise it would be almost trivially easy to always throw them back. (Though I think it might be a little harder in MW2 online, SP seemed pretty easy, though.)

In other words I'm fairly certain I've been killed many times when it didn't say throw back. (Aggrivatingly sometimes after I could have thrown it back, but didn't react fast enough and then it rolled just out of reach.)

It would be amusing if you could attempt to throw back semtex only to have it stuck to your hand. hehe

[mannon]

I think it's too late for the bro bro thing, bro. But it's all good, at least you RTFMed.

[bradqqqqq]

I said the throw back radius is the 300 damage thing.

[mannon]

OH, well no. The 300 thing is the dead center of the explosion. Which probably isn't even possible unless player origins are on the ground instead of body/head, but I think the origin is litereally at the camera's location. Could be tested using 'nades and a small drop or low wall or something.

[bradqqqqq]

Thats almost what I meant but whatever.

I think I missed out on the huge post count because I was too literal in my interpretation of the aptitude test.

I made a few posts, and then put it in my first new thread later, but didn't get my little star until I posted like 25 times.

Anyway, I'm almost positive it's the shortest distance to any of your hit boxes. Head would be too far in most cases where the grenade's on the ground.

[mannon]

Not when it does some 300 damage at point blank, and no humans are 5.777 meters tall. ;p Remember, meters not feet, that's a pretty decent range with a diameter over 11.5 meters wide. Your height would only let you stand horizontally slightly closer before being caught in the kill zone, though if you can climb up on top of things it might help more.

As for the bro, bro thing... I dunno. I had posted before, but not registered my email addy. So then I verified my email and I did it on my first thread. It's all good, though.

[dchoi41]

I mean to say it didn't go into my first post, but rather into the first thread I started myself.

As for grenades, I believe I recall Den saying that it hitscans to any exposed part of your body, so being partially behind cover doesn't protect you. If that's the case, I can't imagine them doing the distance check to some other part of your body to determine the damage.

Since the grenade indicator in MW2 is still at 250, it is likely that both the Frag still has a 256 inch blast radius.

Damage is 300 only at the very center of the blast, and gradually decreases to 75 at the very edge.
The MW2 Frag looks to have a blast damage of... around 175 to 150 at the center, 25 at the edge.
It also has a direct impact damage of 15.

While I can't see it in MW2, it probably works exactly the same as WaW and COD4. Debug Mode shows a series of hitscan lines emitting from the center of the blast to any body parts to which it has direct line of "sight".

The Frag Grenade sends out a series of hitscans to the player model's torso and extremities, if any body part is exposed to the detonation, it will hit the that body part and deliver damage based on whichever limb was closest.

PS: I do the post count bump manually, so it may take a while for me to see it.

Ahhh very cool! I'm actually quite glad to know that it's not just based on the player origin like some older games. I always disliked that method, in fact it was very abusable. You could literally hide just behind a thin pole. As long as you couldn't see the 'nade you were safe. O,o

No wonder blast shield is so good. Hell if blast shield is 0.45 instead of 0.65 then even a point blank grenade is survivable. You could just sit on it like an egg. Unless they use Danger Close, of course, and then you're screwed.

So the Frag Grenade for COD4 pretty much kills everything from the center of the blast to right to the edge then?

and my god.. have you really posted 10 Mill?

You joined today and posted 10000 already.

Do not question the Den, for his power is awesome within his domain. ;p
