@hacker45(View Post) If things start getting more and more complex, like ions as you suggested, then we need more and more variables. For these you'd need two more, one negative and one positive. And these would need to be in every element they effect as well, as well as the code for the reactions they would cause.
i think it's a good idea but this has been suggested before if i'm right. this would make tpt more interresting ofcourse but i think there is a lot of recoding needed. maybe implenting positive wire pwir and negative wire nwir (not like wire more like metal so pmet or nmet could also be a name). but if you talk about all elements then every electronic needs recoding i guess. for example btry should have a positive and negative pole, and the reactions should be changed like positive spark on water makes o2 and negative makes h2o.
