Hi guys! Recently, I have been planning on making a smelter, and the following thing occured to me: "What if there was a tool that could check the propreties of an element?" My idea is, an element that checks the temparature and pressure of the location it's in, and it's ctype is set by the surrounding particles. The particle can then be clicked on, and a sign will pop up. Into a text field you would then type, for example, "Temp>1273", or "Ctype=LAVA". Then, if the temparature of the particle becomes greater than 1000, or it's ctype is lava (for example 2), the particle will produce a spark, which can be accepted by a semi-conductor, eg. NSCN. This would be really useful for a smelter type save, but would also be useful in a lot of other example, for instance, controlling the pressure in a nuclear reactor, or setting of a bomb.
