Fri 4/29 Chapter 10 Exercise

4. Define a mechanic for a trap that harms a character when it detects the character’s
presence and then must wait for a period before it can detect another
character. Document the condition that triggers the trap (the nature of the sensing
mechanism), the character attribute(s) that change when the trap is triggered, and
the length of the reset wait period. Incorporate one or more nonuniform random
numbers to determine the amount of damage done and explain how they are computed.
Indicate what states the trap may be in and what causes it to change from state to state.
Include a vulnerability in the sensing mechanism that could either
(a) set off the trap without harming a character or (b) allow a character to move
within range of the trap’s sensor mechanism without setting it off. (For example, a
pressure-sensor in the fl oor would not go off if the character weighed less than a
certain amount.) Propose a means by which a clever player could exploit this vulnerability to avoid the trap.

The trap is a Magnetic trap. The magnetic trap detects any metals within 7yards or 21ft. Once within range the trap triggers its powerful magnetic field to strip the person of all metal objects including weapons. Once the trap picks up an object it resets leaving a 5sec window before it completely resets. The magnetic force of the trap will inflict 

15% of the players health. The damage is only inflicted if an object is stripped from the player. 15% Damage per item taken away. A huge rise in temperature can cause a malfunction with the trap completely disabling the trap. The temperatures will need to exceed 125 degrees. The outer ring in the picture is the detection range of the magnetic trap. The inner ring is the range in which the magnet can strip you of your weapon and inflict damage. 
(Ignore the labels that say radiation)
The character could just toss a metal device into the detection range to trigger the trap and leaves the player a 5sec window to get past the trap. He/she could also use an item that exceeds 125 degrees to cause a malfunction in the magnetic trap completely disabling it. There is no way to avoid the trigger or the trap once within range. The player can only trick and force a trigger to get by it or disable it all together with something really hot.
