现代背景的真实狙击手游戏,一定是现代的,别把时代扯远了

真实的狙击训练软件有啊~叫long range shooting simulation v2.02,你去google搜下大把种子。文件也不大，十几二十mb，但是要用虚拟光驱打开。想要真实？呵，这游戏要考虑的有：

主要因素：重力和风力

次要因素：温度，湿度，海拔，气压

而且一般都是上千米的狙击....

初次玩可能lz啥都看不懂.....因此软件有自带“classroom"部分，教授理论知识，全英文，不过高中的英语数学物理水平足矣。

一下是该游戏的一点资料

模拟的狙击枪有3 种.308的AR10、.338和.50口径主要是对单动旋转后拉枪机精确步枪Windrunner（追风者）。

使用瞄准镜是Leupold公司的Mark-1A

操作和我们使用的完全不同，有兴趣的可以研究下。

单位全部采用英制。

先对界面介绍一下，左上角几个下拉的卡片，

第一个是Range card

这个卡是在标准条件下（ 500英尺高度, 温度59°F华氏度, 78%湿度, 标准大气压）的弹道修正数据。

第二个是高度，气温，湿度卡

第三个是当前目标的说明

第四个是子弹数据

第五个是计算公式

下面CALCULATOR有附有计算机，点ON打开

修正使用键盘方向键

例如第一个

因为他给的温度和湿度都是标准条件所以就不必考虑

先测出距离，他给出目标边长12英寸

用密位线测得目标长度为0.8mil测得距离为417码

根据距离卡得知400码上升瞄具7.25moa 450码

420码则修正8moa

根据风速旗测得风速15mph

距离卡上400码的风偏修正是1.2英寸450码修正1.6英寸

算得15mph需要修正21英寸1moa在420码对应的弧长是4.4英寸

21除以4.4等于向左修正4.77moa

因为Leupold公司的Mark-1A的修正手轮一MOA只分成4分，我们只能修正到4.75MOA

试试看灰常精准，弹着在十字正中

下面是操作狙击枪的一些小知识

Minute of Angle角分法

Circle : a closed plane curve every point of which is equidistant from a fixed point within the curve .

Webster

To understand what the term “ minute of angle “ means , we first look at a circle .

在了解角分法之前，我们首先观察圆周。

There are 360 degrees in a circle.

环绕圆周一圈是360度

By definition there are 60 minutes of arc (or angle) in one degree.

按照定义60弧分是一度

1 degree = 60 minutes of arc

一度等于60弧分

360 degrees multiplied by 60 equals 21,600 minutes of angle in a complete circle .

360度乘以60等于21,600弧分呈一个完整的圆周。

Circumference = 2πR

圆周等于2πR

Where

那么

R = the radius of the circle and π=3.1416

The circumference of a circle equals 2πR.

圆周等于2πR

21,600 minutes of angle (circumference) equals 2 times (3.1416) times R

21,600角分（圆周）等于2乘以3.1416乘以R

21,600/21600=6.2832/21,600R

1=0.0002908R

For any radius (or Range) one minute equals .0002908R

对于任何半径1分度等于0.0002908R

If R equals 100 yards which is 3,600 inches, one minute at 100 yards is .0002908 × 3,600 or 1.047 inches.

如果R等于100码那么就是3600英寸，一分在100码里是0.000208×3600等于1.047英寸。

One minute of angle covers (or subtends) a distance of

一分角所包含的距离

1.047 inches at 100 yards or,

5.235 inches at 500 yards or,

10.47 inches at 1000 yards.

帮助：这个回答是6.282 6×1.047=6.282

1 minute of angle equals 1 inch at 100 yards.

1分角的弧度大约等于1英寸在100码处的长度

For practical purposes 1 minute of angle at 100 yards is rounded off to 1 inch. This value is close enough and easier to calculate for range work. Note: at extreme long ranges the 1.047” value will give more accurate results.

在实际应用中1分角在100码所对应的弧长一般四舍五入为1英寸。这个接近值对于计算比较容易对于距离计算已经足够了。注：在远距离使用1.047英寸计算将会得到更精确的计算结果。

Suppose you have your rifle zeroed for 100 yards. You now want to engage a target at 450 yards. You range card gives an elevation of 9.25 moa at 450 yards.

假设你把你的步枪在100码处归零。你现在要射击450码的目标。你的距离卡上给你的是在450码上升9.25moa。

We know that at 450 yards 1 moa equals 4.5 inches, so this tells us that you need to aim 41.6 inches (9.25×4.5) higher than your 100 yard zero point in order to hit the center of a target at 450 yards.

我们知道在450码1moa等于4.5英寸，因此这告诉我们你需要瞄准抬高41.6英寸(9.25×4.5) 以便你的100码归零点在450码命中目标中心。

If your scope has a quarter-minute adjustment, you would need to dial in 37 clicks (4×9.25) for a 450 yard target.

如果你的瞄准镜有四分之一分角调整器，你需要调谐37格(4×9.25)对准450码的目标。

Some scopes have 1 minute or half-minute adjustments. Others have more precise adjustments of eighth-minute clicks. Quarter-minute adjustments are precise without the tedious setting of 1/8 minute clicks. Half or one-minute adjustments are too gross for precision accuracy.

一些瞄准镜有1分度或半分度调节器。其他还有用更精确的八分之一分度调节器。四分之一分度调节器没有冗长的1/8分度调整精确。半分度或者一分度调节器又太欠缺精确。

If you think in minutes rather than inches, adjustments can be made easily. For instance, suppose out at 800 yards you are off from center about 8 inches. This is one minute at 800 yards. Make a one-minute adjustment to your elevation to be centered on the target.

如果你想在分度替代英寸，可以做出简单调整。例如，假设在800码距离中心有8英寸。这是1分弧度在800码距离的长度。在调节器上调整1分上升角度准星正好在目标上。

TEST

This is the result of a hit on a 20” diameter target at 700 yards. How many minutes do you want to increase your elevation to hit the center?

测试

这是在700码射击20英寸的结果。要命中圆心需要提升多少分度？

HELP

An answer of 1.4 to 1.43 will be correct.

Reason: you want to increase the distance by about 10” to hit the center of a 20” diameter plate.

Since 1 minute = 7 inches at 700 yards, divide 10 by 7 and you get 1.4286.

帮助

回答1.4到1.43都是正确的。

理由：你需要增加距离大约10英寸命中20英寸直径的盘子圆心。

因为1分度等于7英寸在700码的距离，用7除以10得到1.4286

The wind drift is given in inches for a 1 mph full value wind rather than in minutes-of-angle on the range card. This is to allow for more precise measurements in the field.

在距离卡上风偏是用英寸标示每1mph风速偏差而不是分角。这是为了在作战中跟精确的测量。

You will need to calculate the minutes for your windage setting once the velocity, direction and range has been determined. See the wind and Rang Card classrooms for more information.

在方向和距离已经确定的情况下，你还要计算分角的风速偏差设定速率。见风和距离卡的章节获得更多信息。

Mil Dot Ranging密位点距离修正

The mil dot reticle is the standard in tactical rifle scopes. The mil scale can be used just like a ruler to measure the height of a target. If the actual size of the target is known, then the range can be calculated using a simple formula.

密位点十字线是标准的战术步枪瞄具。有了密位刻度就像使用标尺测量目标高度一样。如果实际目标的尺寸是已知的，那么就可以用简单的公式计算出目标距离。

Modified mil dot reticle , Elevation knob , Windage knob

Put the mouse cursor over the elevation and windage knobs to see the tops.

放置指针在上升和风偏旋钮上可以看见旋钮上部。

In the simulations you will be using a modified mil dot reticle. One difference from a standard mil dot reticle is that a fifth dot takes the place of the broad posts at the edge of the field of view. This reticle is a wire with 1/4 mil dots spaced 1 milliradian apart. There are 5 mils between the center cross hairs and the center of the outside dot.

在模拟器里你会使用到改良的密位点十字线。唯一区别标准密位点十字线的是第五点代替宽广布置的视野。这个十字线是1/4密位大的细圆点隔开1个千分之一弧度画分的。从十字线中心向外各有5个密位。

In this reticle, the dots are actually more oval than round. The length of the dot is 0.25 mil .

在这个十字线里，圆点实际上比较椭圆。它的长度是0.25密位。

Size of target (yards) ×1000/Size of target in mils = Range in yards

目标尺寸（码）×1000÷目标在密位刻度的尺寸=距离（码）

A milliradian is an angular unit of measure. 1 milliradian equals one yard at 1000 yards and 1 meter at 1000 meters (see Minute of Angle for explanation ). If you know the height of the target (in yards) multiply it by 1000 and divide by the mil dot size of the target to get the range.

千分之一弧度是一个度量单位。1千分之一弧度对应1码在1000码和1米在1000米的弧长（看角分法说明）。如果你知道目标高度（单位：码）乘以 1000再除以目标在密位点上的长度就得到距离。

不过这游戏练得都是靶子，没人给你爆头，以娱乐为主的就算了吧.....
