Hello!

I've come up with an idea for a new element - Positrons, abbreviated as POSI. I've also coded a prototype version of this element which is available from Pastebin, link at the bottom of this post (it may require adjustments and minor bug fixes, but from my testing, it's generally functional and does everything it's supposed to).

This energy-type element is the anti-particle of ELEC, and will counteract it in many different ways. Here are some of its properties:

• Most importantly, it can cancel electric sparks. I know that PROT already does this, however the problem with it is that it only "disrupts" the sparks. You need to apply a large amount of PROT to remove them, otherwise you end up with a huge mess in the conductor, generating endless spark loops, which is doing the opposite of what it should do - remove sparks. With POSI, on the other hand, one particle kills a single spark. It gets removed immediately, not just disrupted, so the other sparks in the conducting material don't get messed up. I think this gives much more desirable results.

• It annihilates with ELEC, generating energy in the form of heat and radiation (PHOT). When a positron and electron meet, they cancel each other out (with a nice flash effect), creating two very hot photons scattered in opposite directions. Perhaps not very useful, but could be considered a new route for producing light and heat.

• Just like ELEC, it slowly charges EXOT, but instead of the coloured oscillating it gets black & white oscillations. When charged to the max, the EXOT explodes, releasing a burst of pressure, as well as a supercharged, superheated form of AMTR that will sweep across the screen, eating any matter it comes in contact with (apart from the indestructable elements, that is). Could be used for making "antimatter bombs" and alike. 

• Also, POSI will "erase" any ELEC activity on EXOT, and vice-versa. Only when the effect of the predecessor is removed, it starts its own charging process.

• Similarly to PROT fusion, 2 particles of POSI can fuse into a particle of AMTR, when collided at higher velocities (suggested by Alt-Factorial).
  

Other less significant properties: It will clear the effect of ELEC on LCRY.

I also wanted to create a rarely occuring "positronium" state in which a POSI and ELEC orbited around each other, eventually annihilating, but this turned out to be too buggy and it lacked any purpose besides looking kinda cool.

Due to the fact that creating this element involved slightly changing the code of some other elements, I have posted the new codes of these elements as well, with the changed parts marked by being put between /*NEW*/ tags:

POSI.cpp

AMTR.cpp

ELEC.cpp 

EMBR.cpp

EXOT.cpp

SPRK.cpp

I do realise these kinds of things are best done by doing a pull request, but I didn't feel like setting up an account just for this (I will do that the next time, if there will be a next time). Hope this isn't much of an inconvenience.

This is all I could come up with, but any additions or elaborations are welcome. I thought if the devs don't like the idea, someone might like to use it in a mod.

 I added your suggestion, now you can fuse POSI into AMTR at high velocities.

(I totally didn't just look up the code from PROT or anything...)
