This .oxp reduces the masslock radius of a ship according to its mass.

Ship name	Mass	Masslock radius (r=mass*0.02+17000)
Adder         	16 t	17 km
Gecko        	25 t	17.5 km
Sidewinder	25 t	17.5 km
Viper        	34 t	17.7 km
Mamba         	36 t	17.7 km
Moray        	51 t	18 km
Cobra Mk I	52 t	18 km
Fer-de-Lance	53 t	18 km
Asp          	76 t	18.5 km
Krait       	93 t	19 km
Boa           	182 t	20.5 km
Cobra Mk III	215 t	21 km
Boa2         	216 t	21 km
Python      	267 t	22 km
Anaconda	438 t	26 km

You can't use Torus drive in combat situations due to red alert, regardless of these distances!

The Torus drive will turn off when a new ship arrives into scanner range but you can re-engage the Torus drive until your alert level is green.

Ships over masslock range are marked with a darker yellow 'lollipop' in green alert.

Torus will turn off when there are asteroids, buoys, cargo boxes or mines on a collision course (to slow down in time and help prevent an impact).


Do not unzip the .oxz file, just move into the AddOns folder of your Oolite installation.
