Wired Defusable C4 (E2)

[Rad Hazard]

Here's something else I made in my spare time.

My step-brother gave me the idea when he wanted me to make him a wired bomb that exploded after a certain time. I played around a bit more after I finished and came up with this:

There are three types: (I only showed one in the video, others are the same except for the additions.)
Normal: Normal C4 I showed in the video. Can be defused after activated. Can be turned on with "arm" button, but can't be turned on again.
Sticky: Same as normal, but has a grabber on the bottom. Grabber can be activated/deactivated by "arm" button.
Indicator: Same as normal. Has 3 hud indicators that display time left, defusal time left, and whether or not it's defused.

Info:
Detonation time on all three is 60s
Time to defuse on all three is 10s
Defusal time is automatically 1/6th of the detonation time.
The beep and light go faster and faster as detonation time approaches

Here's my E2 code. (Yes, I know that it could definately be optimised)

@name Defusable Timer
@inputs Time On Defuse
@outputs TimeLeft Boom DefuseLeft Defused Beep
@persist A B On2

interval(100)
if (On) {
    On2 = 1
}

if (Time) {
    if (On2 & !Defused) {
        if (!A) {
            A = Time
        } else {
            A = A - 0.1
            TimeLeft = A
        }
        if (B <= 0) {
            B = 9 * (TimeLeft / Time)
            Beep = 1
        } else {
            B = B - 1
            Beep = 0
        }
    } else {
        TimeLeft = Time
        A = Time
    }
} else {
    TimeLeft = 0
    A = 0
}

if (Defuse) {
    DefuseLeft = DefuseLeft - (60 / Time)
    if (DefuseLeft <= 0) {
        Defused = 1
    } else {
        Defused = 0
    }
} else {
    DefuseLeft = 100
}

if (A <= 0 & On2 & !Defused) {
    Boom = 1
} else {
    Boom = 0
}

Cool

You should add a HUD indicator to it that sticks a progress bar on your screen showing diffusal progress.

Actually, the indicater version already has that. I didn't show it in the video because sorce recorder wasn't playing nice and i got bunch of lua errors when I spawned it.
