Description

Problem of almost all heavy machinery in Arma3.
Correction of an aim scale on range works. But the bullet always does not lay down in a scale cross hairs. On each heavy machinery the bullet lays down on a miscellaneous from a cross hairs of an aim scale. Some low to the left. Some it is low in the right.
It occurs at different distances to the purpose. At distant distances it is badly visible, but too occurs. Machine-gun shots repeat a problem.
How it works in Arma3. By changing the firing range bullet hit no interface with horizontal and vertical lines, according to a laser rangefinder.

The offset axis ballistic computer AI from the optical sight AI. AI does not need a grid at the sight optics. For live players should not be such ballistic displacement axis.
Especially critical look at the displacement Slamer. To hit the target, the sight axis must be higher than the target.

Steps To Reproduce
  • Virtual arsenal
  • Garage
  • Choose test Slamer, T100 or Kuma
  • Try to shoot at a target, any distance. Correct range of a shot on a sight range finder. As you can see, correction works for range of a shot not truly. The bullet of the main tool and a machine gun gets always below the horizontal line of a viewfinder of a sight at any distance of a shot. The bullet of the main tool and a machine gun never comes nearer to the vertical line at any distance of a shot.
  • Return to Garage
  • Choose Marshall
  • Try to shoot at the purpose at any distance. Correction on a range finder works for range of firing. The bullet of the main trunk almost truly gets to a target on horizontal and vertical lines of a viewfinder of a sight. The bullet of a machine-gun trunk loses correction, leaves in left from the vertical line of a viewfinder of a sight.

I like you Lex but i dont know ,your tickets are funny. Again everything works like it should. The optics are not IN the gun they are next to it. Thats why this effect occurs more on short distances. What you actually want is a focus system that works like that: 1. Set Zeroing to e.g. 200m 2. Firecontroll gives the conversion point of projectile and aim line. 3.Scope system focuses on that point so you can use the crosshair. Make a feature request for that and i upvote,but this is the way arma optics work and i dont know how far it is possible to change. This idea of the aiming system would be usefull in other vehicles too

Ridiculously, it when laws of geometry do not work. The cross hairs in optics, glass with graphic drawing, has to carry out the role. The laser range finder will define distance to the purpose. The shooter changes range. Distance from optics to a trunk a constant. Changes only it is long trunk axes to the purpose, and it is long optics axes to the purpose, and a corner between them. The adjusted mechanics makes the amendment to the provision of a sight. It everything is tested at stands and adjusts fire on a shooting range. The mistake should not be.
Present, at you one eye is a trunk, the second eye is optics. Muscles of eyes correctly focus a look at different distances.
As in Arma3 it does not work, it is necessary for us the help of the oculist from BIS.

What you mean are binocular aiming sights used in WW2. Today you use only 1 monocular optic with an autofocus(cheaper optics but needs a computer).I dont know if it is possible to adjust the angke of a sight in arma. And normally every tanker knows that you have that difference in aiming. You btw have on the habdguns too just less.

Lex added a comment.Jul 25 2015, 3:04 AM

I explain as the trunk and a sight of targeting in the tank works. In game a divergence of optics and a trunk. The bullet never hits the mark on the center of optics. Places of hit of a shell in the concrete block (in pictures) not in the center of optics.
This divergence remains, at any distance, firing from any heavy tool in Arma3.
The bullet has to hit the mark (rupture of a bullet), in a place of the center of optics. In pictures not flight of a bullet, is a gap on the purpose.
With such divergence of optics there is every chance not to hit the mark. When the purpose at distance looks less than this concrete block in a picture.
Machine gun of the main shooter on the tank, the same divergence.
Come into a virtual arsenal of Arma3, try do some shooting from all types of heavy machinery, from the main tool, and from a machine gun of the main shooter.

It is so visible, the center of optics in the place, defeat of equipment in other place.

You dont get the point. The scope is zeroed right and the gun too. But they are in different positions, because you cant put the scope in the gun.For example just to understand : take a MXC put on a RCO use the reddot. Go close to the wall aim so the sight is slightly above the wall. When you shoot the bullet will hit the wall because your scope is higher. Same for the Tank. Like i said what you need is an autofocussing scope for the tank and at this point i dont know what the limitations of arma are. It sounds easy to make such system. It even is quite simple but there you need an onthefly adjustment of the scope.

Lex added a comment.Jul 25 2015, 3:03 PM

There is a term - zero adjustment of the line of a sight of the tank. It allows to synchronize the difficult mechanism of a sight. Synchronization of the line of the channel of a trunk of a gun with the line of the channel of the center of optics (viewfinder) is made. After these actions, the difficult device of an aiming changes a trim in a sight prism, constantly combines the line of the channel of a trunk with an optics cross hairs.
The sight of the shooter of the tank is the difficult device intended for an exact aiming.
Changing range of firing the bullet falls below or above the horizontal line
sight cross hairs. If the device is adjusted truly, the bullet is not lower or higher than lines of the horizon in optics. If the device is adjusted truly, the prism will change a trim on range and will displace a viewfinder to the left or in the right, considering distance to the purpose, a trunk axis corner to the purpose and an optics axis corner to the purpose.
The optics in the tank, is the computer system of devices for an accurate shot. It not simply the field-glass inserted into a tower.

You when read this text, at you that, the left eye at the beginning of a line, and right in the right, in the middle of the line? Try to incline the head to the left and to the right. What is still worse? Or all of you still can read?
It is also the principle of zero adjustment of the line of a sight of the tank.

There is no active lead correction in vehicles FCS, so everything is working right here, ticket can be closed.

Lex added a comment.Jul 26 2015, 11:58 AM

Reconsider pictures. The bullet never comes to the purpose on the horizontal line of a viewfinder (the distance to the purpose is kept and range of a shot is adjusted).
The bullet never comes to the purpose on the vertical line of a viewfinder. For what then the viewfinder reference point if the aim tag is not a reference point is necessary.
http://stroybat.ucoz.ru/raznoe/Gun/1.jpg
In a picture the maximum distance for a shot from the tank. The position of the tank is open. The viewfinder is aimed at a tower, got below a tower. Considering a curve viewfinder, I put a viewfinder above and to the right from the center of a tower I get to a tower. And if the tank is not completely visible and where there will be time for adjustment fire from a position?

Lex what the guy means is thats not a bug. So this ticket needs to be closed. when you want such feature like that auto adjusting scope -> Feature Request

Its not meant to be mean but this is how the rules in Bugtrackers are.

Cool or not?

There is nothinh like you mean no time to aim or you dont know where to lead. There for you have the Virtual Garage. And i think you are not 13 like some people in Arma so you can use the Virtual Garage to learn your vehicle properly.

Or create unit in editor and add this allowdamage false - and your unit will be undestructable and you can learn how to use tank FCS on move, firing to mobile targets

Lex added a comment.Jul 26 2015, 12:19 PM

Such function in the tank is not present, what to twist a viewfinder in left, to the right, in top and down during fight. It works automatically and is put in a sight, is regulated at the tank exit in the conveyor.
In fact even the manual choice of range of a shot in the modern tank it will automatically coordinate a viewfinder with a trunk type of a charge and ballistics.
Tanks where had no calculator, the viewfinder had the saturated graphic table for an aiming, determination of distance, anticipation of fire on a moving target and many other things.

I really dont understant what youre mean, but this function may be implemented in " Initialization " field, while creating untis in editor

Lex added a comment.Jul 26 2015, 12:56 PM

It is more similar to a mistake, or a defect, and demands correction.
On each tank the size of an error of deviation of a viewfinder of the shooter is constant, but at each tank the direction of a divergence the individual.
Such mistake is not present for example on Marshall.

This is working as in real. Deal with it.

Lex added a comment.Jul 26 2015, 1:15 PM

I do not see any reality in it. You consider presence of such mistakes at game attractive?

THIS IS SIMULATOR, ITS NOT MISTAKE, IT IS LIKE IN REAL. THIS IS NOT ARCADE GAME LIKE BATTLEFIELD OR MEDAL OF HONOR. DEAL WITH IT OR SIMPLY STOP PLAYING, IT WILL NEVER BE CHANGED

In what a charm to feign a curve shot? It does not work so in realistic model.

Not a bug

Its not a bug. In any modern tank range is not calculated utomaticly, you need to lase the target, THEN range correction is done.

Lex added a comment.Nov 11 2016, 7:02 PM

Its not a bug. In any modern tank range is not calculated utomaticly, you need to lase the target, THEN range correction is done.

Put infantry of AT on 2500 meters from the tank. Try that that to generate to include AUTO and to shoot.
At you it won't turn out to include AUTO for firing at infantry or at the building. There is no button of inclusion of AUTO. The maximum distance of 1900 meters on the optical center. Everything that further than 1900 meters, to shoot as will turn out.

Well, this is easy fixable (RHS have done same as ACE) - player should be able to lase everything, just like laser designator work for now, Bohemia try to implement this. Lasing target (ground, building, infatry, vehicle) and measured range is putted into FCS, then correction for range should be taken. No need for squares (vanilla target lock signature) on screen, player will know where he is aiming to.

Also SABOT round have limited effective range, HEAT rounds same as HE-F can be fired longer, you need to take this in consideration (Bohemia) I can share good info about tanks available now in gaem (or its equivalents in real life).

HE and HEAT are slower round so their trajectory is much higher and shorter than the SABOT ones.
For long shots SABOT is better.
About effective range 2.5km frontal hit on kuma is not deadly. Side shot about 3km.

Lex this ticket is closed due to not a bug.
I try to explain the problem.
There are different lines.

  1. Trajectory of the ammo
  2. Line of aim of the barrell
  3. Optical line

What you mean by the zero on the crosshair is the optical line. Thats not where the barrell is aiming at. But its parallel. That means the correction is always the same 40 to 50 cm (maybe more i didnt measure it exactly). So on short distance you have to account that on log distance not really. Its the same with rifle scopes that are high. When shooting on short distance you have to aim higher. If the correction has to be made left or right depends on the construction of the tank, so where the visor is reletavly to the cannon. If you ask wha there is no horizontal correction, because it would be 1 more part with a huge amount of technology. In the current state you have visor and barrell parallel on the same controls. The correction would need the visor to change that angle horizontally depending on the distance.

BTW the youtube video with the Marshall shows the exact same problem. All hits were about 20cm left. Like the barrell is 20cm left of the visor.

In the first seconds of video - axis offset ballistic computer AI,
for an explosive charge HE, T-100 on. Centre sight arrow above the target. But AI is on target. Keeping sight position, your shot is off target.

https://youtu.be/2SHxhEWiyQw
How it works ?
AI gunner is ballistic eyes on the target?
In 99,9% AI arrow hits the target.
tank gunner player has no ballistic correction optics, optical center does not match with ballistics barrel in most situations. The only factor drawing and the brightness of the green square to the target.
Manual adjustment of shooting distance does not correct ballistics shot to the center of the sight optics. Correction takes place relative to the horizontal line of sight optics.
When the tank is not smooth, with a slope of the hull to the left or right arrow frame optical sight and the commander will also have a slope. The reason for the absence of angular stabilization optics. tank gunner player has no reference points on the lens for precise shots are usually necessary to make a few shots, to their own adjustments. To speak in this case about the shooting at a moving target does not make sense. You do not have any reference points in the sight and ballistic capture no purpose.
The tanks used games mesh sighting frame scopes modern tank with onboard ballistic computer, the capture and target tracking. Implemented all only arrow AI, no implementation for the player hand.

Personnel at the end of the video clip show -
The total lack of inclusion AUTO correction distance for a shot discontinuous in the infantry.
Laser lights drone did not help to do it.

The Barrels of the Kuma and slammer are left of the gunner scope and the Barrell of the T100 is left.
The Crews on tanks can work with such corrections, because they use 1 Tank all the time.
AI does it Players do it. I mean Kuma and Slammer goe 0.5m down and left , T100 0,5m right and down. Thats it
The firecomputer against Infanty is some thing different. I would prefer to higher the max manual range for that maybe on 2.5 km

The Hit with the marshall was still left of the marker

If there is a ballistic computer on board:

  • On board there are semi-automatic ballistics
  • Optical sight gunner and tank commander

set up at the site. Lead ballistic barrel in the optical axis zero sight.

  • All the other amendments to the optics on the sighting frame with a wide range of scales on the angle correction of sight.

If there is a ballistic computer on board:

  • Optical sight gunner and tank commander

set up at the site. Lead ballistic barrel in the optical axis zero sight.

  • Frame in the optical sight, such as is now in the game. No frame with a wide range of scales on the angle correction of sight.

The game is not old-fashioned tanks. For this reason, a request for the correct operation of the ballistic computer. This function should be in a modern tank and not a substitution of this function, the ability to perform calculations AI ballistic computer.

If you want to calculate ballistics version as on the old tanks, ask add to "the DLC Tank" old tank samples.
I even agree if they both versions of ballistics in the game. Let this filling depends on the difficulty level of the game.

What I wanted to say - this is implemented in RHS mods. In the video you will see how the correction of the barrel after the determination of the distance to the goal. Correction is depending on the type of the bullet\the distance\the design of the tank. This is what is called correction of "0" when in the ballistic computer takes into account the design features of the tank. The location of the barrel relative to the sight arrow is taken into account and it adjusts the stem along the horizontal and vertical marks in the optical sight. In case of correct estimation of the distance the bullet aims at the center of the sight, is the main calibration , which are all the tanks in the world.
