Damage Sensor

[Maximized]

How about a sensor that records how much damage is done to it? This could be fun for tank wars or something like that so your guns won't work for example if the damage sensor on that gun is hurt too much

Explosives have health parameter, and you just have to configure it.

wired explosives don't output their health, they can just be set to go off when they = 0.

also the suggestion of an object that increases an output as it takes damage isn't entirely bad, then again its very easily duplicated with the explosives if the health can be output from it.
