HUD Angle Calculation.

The HUD angle, also known as the heads-up display angle,

is the angle between the player's point of view and the

center of the HUD. This angle is important for determining

the player's field of view and for ensuring that the HUD is

properly positioned within the player's view.

There are two common methods for calculating the HUD

angle:

1. Using the camera's field of view: The camera's field

of view is the angle of view that the camera can see. This

angle can be used to calculate the HUD angle by subtracting

the camera's field of view from 180 degrees. For example,

if the camera's field of view is 90 degrees, then the HUD

angle would be 180 90 = 90 degrees.

2. Using the player's eye position: The player's eye

position is the position of the player's eyes within the

game world. This position can be used to calculate the HUD

angle by finding the angle between the player's eye

position and the center of the HUD. This angle can be

calculated using the following formula:

HUD angle = arctan(HUD position.y eye position.y, HUD

position.x eye position.x)。

where:

HUD position is the position of the center of the HUD

in the game world.

eye position is the position of the player's eyes in

the game world.

Once the HUD angle has been calculated, it can be used

to position the HUD within the player's view. The HUD

should be positioned so that it is centered within the

player's field of view and so that it does not obstruct the

player's view of the game world.

HUD角度计算方法。

HUD角度，也称为平视显示器角度，是玩家视点与HUD中心之

间的夹角。此角度对于确定玩家的视野以及确保HUD在玩家视野中

正确定位非常重要。

有两种常见的HUD角度计算方法：

1. 利用摄像机视场，摄像机视场是摄像机能够看到的视角。此

角度可用于通过从180度中减去摄像机视场来计算HUD角度。例如，

如果摄像机视场为90度，则HUD角度将为180 90 = 90度。

2. 利用玩家眼睛位置：玩家的眼睛位置是玩家的眼睛在游戏世

界中的位置。此位置可用于通过找出玩家眼睛位置与HUD中心之间

的夹角来计算HUD角度。此夹角可使用以下公式计算：

HUD角度 = arctan(HUD位置.y 眼睛位置.y, HUD位置.x 眼睛

位置.x)。

其中：

HUD位置是HUD中心在游戏世界中的位置。

眼睛位置是玩家的眼睛在游戏世界中的位置。

HUD角度计算完成后，可用于对HUD在玩家视野中的位置进行

定位。HUD应位于玩家视野的正中心，且不应妨碍玩家对游戏世界

的视野。
