This script furthers your laziness.
Feature 1: Installed missile data display
When you change the currently installed missile, it displays data about that missile type in the subtitle.
(yes, it would be helpful if you had subtitles enabled in your game options)

WHAT data is displayed and in which order is controlled by the script's text file.
X3:TC: t\7073-L044.xml
X3:AP: addon\t\7073-L044.xml
You want the missile name on the right of the line? Set it's sort order number to 40 or so.
Want the "dumbfire" tag shown as the first thing? Set the sort order to 1.
Want no missile name displayed at all? Set it to 0.
Want more spacing?
Add more spacing.
It's a text file...
How often the script checks up on the installed missile and for how long the subtitle stays on screen... those values can also be edited there.
The available data fields are explained in the text file but I'll explain the ones you get with the installation default. (and see in the screenshot)
3 / 1063
You have 3 of these missiles in the cargo bay and you need to fire 1063 missiles to destroy your current target - assuming all hits.
Wasp Missile
The name of the missile.
If the current target is within the missile's max range, it is shown in green, otherwise in red.
560 m/s
The missile's speed.
If the missile is 15 % faster than the current target, it's shown in green.
If it's slower than the current target, it's shown in red.
These percentages can be changed in the text file.
18 km (target +11 km)
Two displays for the same thing.
18km is the missile's nominal range.
You can also see that my target is 6.88 km away. That means the missile's reach = target +11 km.
That way you can see how "in range" the missile actually is.
Dmg 8x 1000 (D 8000)
Two displays for the missile damage.
For personal use I'd probaby disable one of them.
in range
Somewhat redundant given that the display colour of the missile name already tells you that but if you want it spelled out... there it is.
SWARM
This is a swarm missile.
These missile tags are read from the engine directly.
Other tags would be FF (friend foe recognition), PROX, Manually detonated... the usual suspects.
Feature 2: Targeted missile data display
If you target a missile in space (maybe because it's incoming to your ship) the same display is given.
If does not automatically target any missiles.
The comparison stats of the target ship are now... those of your ship, regardless of where the missile is going.
So... if the display tells you that there is one missile required to destroy the target... you should do something about it. Real quicklike.
Same goes for the missile range or speed display.
If the speed is listed in red, your ship is faster than the missile.
You could just fly away.
If the missile is out of range well... it's not going to reach you .
