LOS Through Vehicles

Hi,

it has to do with current CPU power (ie, there is not enough in PCs or Macs). Do a search on LOS and vehicles or something like that. It has been discussed extensively before.

It is amazing what you can learn from a good book...

Yup, even CloseCombat gets it right there! wink.gif

Seriously, something that needs to be adressed but that was pretty much ignored by everybody is the fact that LOS from vehicles is too low. It is thus impossible to achieve a perfect hull-down position 'cos your blind TC won't see anything across the ridge...Even the gunner won't shoot sometimes because he is blind or his eyes were ripped off and put a bit lower on the vehicle...

But we'll have to wait for a patch or maybe CM2 for all these "details".

yup this one has been coverd too death

Steve and Charles and BTS know all about this and we have been told it was a conscious decision based on the inability of consumer level cpu to accruataly keep track of LOS of and LOF of units that are moving during the minute of the turn in a 3D environment.

and yes it should be addressed

Indeed, vehicle-blocking LOS is a CPU issue. However it goes deeper than that. It's also an AI issue. What should a tank do when its LOS to a target is suddenly blocked by a friendly? Should it move? Where? What if it might move into a spot where a new enemy gets a shot at it? Is it worth it? What if it doesn't even know about an enemy that has an LOS to the new location, but you as the player suspect that one is out there? Then is it worth moving? Should it move off the road and maybe get bogged down? Is that worth it? Should it wait until the friendly obstructor moves out of the way? But what if the obstructor ends up not moving after all, because of damage or some other reason, and the time spent waiting is wasted? And of course all this doesn't even touch the issue of "but my tank gun is higher than the sihouette of the nonturreted vehicle in front of it, so can't I get a hull-down status firing over the heads of my StuG buddies?" Which is then countered by people who want to be able to shoot through that StuG to get at the tank behind it, and maybe kill both in one shot, and other assorted minutiae.

In short, we'd be putting a heavy burden on the TacAI to "handle the situation intelligently" and I can promise you one thing: gamers will bitch and moan if the TacAI handles this even one percent less than perfectly. And yet, being an AI, of course it cannot handle it perfectly. So given the fact that it could potentially be a CPU hog, and that the solution would be less than perfect anyway, we decided not to have (nonburning) vehicles block LOS.

Panzer-Leader - I don't know what you're referring to. Hull-down works perfectly well in CM.

Charles, what I'm talking about is that LOS sometimes isn't right from the TC's perspective. I don't know where LOS is calculated from in a vehicle but certainly it isn't calculated from the TC's head...I've got a very obvious picture about this that I sent to CEO. He agreed.

I don't know why, somehow this issue has never been discussed on this board(did an extensive search...)

PL - it's calculated (roughly) from the level of a vehicle's main gun. Otherwise you'd get situations where you could see but not shoot. The proper term for this is "turret down" (not "hull down") and is not simulated in CM.

Well this is confusing. If the shooting arc is unobstructed, even if there is no direct LOS from the main gun I should be able to shoot if my TC has LOS to a target. It still looks like being a compromise but being able to see the target and unable to shoot is very unlikely. What is the picture you have in mind? projectiles do follow ballistic trajectories, certainly I do not need to have LOS from the main gun to be able to shoot a target.

Ummmmmmmm, BUT you gunner wont be able to see the target with his optics if its behind a hill???

So what you are suggesting is that tanks should be able to indirect fire using the TC as the spotter? smile.gif

This is something that was actually discussed some time ago, but it was considered a fairly uncommon practice from all accounts I believe.....

Indeed, at least for Area Target. I do not expect pinpoint precision as the gunner has no optics available for the shot but the TC could provide angle and distance. I am no expert on this but I do not see why not, especially against fortifications/buildings, or barrage fire.

Seahawk,

PanzerLeader was referring to a term known as "turret down" where a tank is almost totally shielded from view by a terrain feature. Only the very top of the turret, or sometimes only the commander standing up in the turret, is visible to the enemy. This allows the tank to spot enemies, but (for the most part) not be fired upon. Of course, its own gun is blocked by the same terrain feature so it really can't fire back from this position (a couple of degrees of angle, at most, won't allow lobbing shells over the obstruction - at least not for direct fire).

The more common position is "hull down", where the body (hull) of the tank is obstructed from view and fire, but the turret and gun are high up enough to be "clear". This means the turret can be hit by enemy fire, but the tank is able to shoot, and its silhouette is much smaller than usual since the hull is protected. You can do this in Combat Mission.

I guess having a LOS for the TC and a LOS for the gunner would tax the CPU alot (okay folks, we just doubled ALL AFV LOS calculations). That would also affect the AI also I would guess. The AI would have to determine if it wants to creep up the hill and risk being shot, etc.

Maybe when everyone has dual CPU's running at 2 GHz, then EVERYTHING (kitchen sink included) will be there.

PS: My prediction is that CM will be THE greatest game released this year, bar none. It will take all awards from all places. Anxiously (wow did I spell that! biggrin.gif) waiting for CM to appear in the mail.
