Large homing missiles 2

Torpedoes combine 3 different fire modes:

1. Guided and 2. unguided modes are just the same as for my previous plane: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=531161469
------------
Here is a short instruction for cockpit actions for guided and unguided modes:
Press "2" to start tracking system. Red blinking light will appear in front of you. This should be done before any torpedo launch.
Press "3" to stop tracking computer. This should be done after attack is complete.
Press "4" to launch torpedo in guided mode. After guided torpedo is launched, use your ship pointing to designate target for torpedo. Use your frontal camera for precise guiding (Press "1" for camera view)
Press "5" to launch torpedo in unguided mode. It will fly forward and require no leading from pilot.
------------

3. Lock-On mode.
Lock-On mode is a completely new feature. It's easy, but requires a little skills and a bit of understanding of how this thing works.

Short instruction:
----------------------------------------------
Press "6" to start locking target (crosshair on target)
Press "7" to stop locking.
Press "8" to launch torpedo in "Interception" mode. Torpedo will calculate interception point and fly towards it untill impact.
Press "9" to launch torpedo in "Hook" mode. Torpedo will try to "hook" moving target to hit from forward direction.


Advanced instruction:

1. Panel Indicators:
Right Panel
--------------------------------------
Lock Stable: true/false - indicates if target locked and if lock is reliable

Ready to Go: true/false - indicates if target velocity measurement is reliable and can be used to calculate interception course. Launch torpedo when these two indicators are "true".

Target data
X, Y, Z - gps of target

Signature - this value is not an exact size of target, but it is relative to targets size. (It is a distance between 2 opposite closest free points around target.)

Distance - distance from torpedo to target.

Velocity - scalar value of targets velocity.


Left Panel
-------------------------

Can Intercept: true/false - indicates if torpedo can intercept target. It's based on current distance to target and its velocity vector. (Ship moving at 104 m/s towards you can be intercepted, ship moving at the same speed away from you can't be intercepted)

Status - current status of torpedo. Can display following values:

Locking - trying to lock target (when you press "6").

Target Locked - indicates that target is locked. If target locked successfully.

Launch - torpedo is launched.

Re-Locking - torpedo is trying to re-establish target lock. One of problems with launch is following: in the moment of detachment torpedo can not keep target in lock till the moment, it leaves bounding sphere of launching plane, cause otherwise plane will spoil target lock. So, there is a lag of 1-1.5 sec between rocket launch and momet it can re-lock target. Torpedo uses last data on target position and velocity to re-establish the lock. So, the more steady is measured target velocity, the less possibility, that you will see following indicator:

Lock is LOST! - torpedo has lost target lock. It happens mostly with small and fast targets, targets moving with acceleration, targets that are too far. This message is not an indicator of complete failure tho. Use your "laser pointer" (press "2") to try to indicate target for torpedo again. In 80-90& torpedo catches target designated by plane easily. When you see "Lock Stable: true" on the right panel, press 3 to turn off "laser pointer".

Chasing - torpedo is moving directly to target, while gathering data needed to calculate interception course.

Intercepting - torpedo is moving to calculated interception point.

FIXED - this indicates final 1-3 seconds before impact. Torpedo interception vector is fixed when it comes closer than 1.5*target signature. Otherwise trajectory will be spoiled.

Terminated - if torpedo has not hit target in 5 min and warhead has not exploded, script turns itself off to free system resources.

Tang Vel - tangential component of targets velocity (it's normal to our line of sight when we look at target)

Orth Vet - orthagonal component of targets velocity (it's collinear to our line of sight). If It's negative, target is approaching, if it's positive - target goes away.

Intercept Time - Calculated time left till impact.

Laser Pointer - X, Y, Z coordinater of object caught by pointer. Helps to understand if you can designate target for torpedo if it lost lock.
