These elements generally don't fit into any other category, and have special properties.

Eraser

Erases particles.

This is used to delete particles on the screen. It is the default action set for button 2 (right-click). To erase signs or walls, you must use the sign tool or the wall eraser, respectively and obviously.

Clone

Solid. Duplicates any particles it touches.

Clone fills the empty spaces around it with its ctype element. If no ctype is set (when you first create the CLNE), it will pick a particles that is touching it.. You can also draw over CLNE with another element to set its CTYPE.

Photons can pass through all types of CLNE (and BCLN) particles.

Void

Hole. Will drain away any particles

Void deletes any particles that fall into it, similarly to to the edge of the screen. However, it cannot delete solid particles, even if they are pushed into it with piston.

One relatively unknown feature of VOID is that if you set its CTYPE to an element, it will only destroy that element. However, this can only be done with PROP or the console, you cannot draw over it like CLNE.

Diamond

Diamond, Indestructible.

Normally can't be destroyed, even with things that destroy everything else, like BOMB. It will only be destroyed if it gets pushed off the screen, is inside a wall that absorbs solids, or is overwritten with another element by DRAY. DMND is commonly used to contain high temperature, high pressure, or other destructive elements. However, it should only be used as a last resort, because there are many, more creative ways, to contain destructive elements.

Vacuum

Vacuum, sucks in other particles and heats up.'

Vacuume acts the same as VOID, except it creates negative pressure, and also heats up as it sucks in particles.

Air Vent

Air vent, creates pressure and pushes other particles away.

Generates pressure

Stickman

Stickman. Don't kill him! control with the arrow keys

Use the left and right arrow keys to move, up to jump, and down to shoot particles. You can change the element that you shoot by touching some of it with your head, but you can't select solids. If STKM goes through gravity wall, it will get rocket boots. EHOLE removed them

Stickman are hurt by heat above 51.85C (325K) or below 29.15C (244K). They are alsot damaged by extreme pressure.? They are also hurt by certain elements, regardless of the heat: -VIRS -ACID -AMTR -URAN -PLUT -NEUT and by elements that destroy all particles: VOID, VACU, PVOD, BHOL, BOMB (only if the middle of the head is inside the blast) PLNT will restore STKM's health

Only one STKM can be on the screen at a time, and if it dies, it will reapear at the SPWN pixel. There can normally only be one pixel of SPWN on the screen at a time, and it is created when you place a STKM (the "STKM" menu item actually creates SPWN!)

Converter

Solid, converts everything into the particle if first touches.

CONV converts all the particles that touch it into its ctype element. If no ctype is set, it will be set to the first element that it touches. You can also set the ctype manually by drawing over it with the element.

Breakable Clone

Breakable Clone.

Like CLNE, but breaks under high temperatures or pressures. While "broken" it can move around while still creating more of the element, and will disappear after 1000 frames.

Portal-IN

Portal IN. Particles go in here. Also has temperature dependent channels. (same as WIFI)

PRTI absorbs falling particles like void, except the particles will come out of PRTO particles on the same temperature channel. If there are no connected PRTOs, some particles can be stored in the portal until it is full and will not accept any more.

Portal OUT

Portal OUT. Particles come out here. Also has temperature dependent channels. (same as WIFI)"

Particles that fall into a PRTI will come out of PRTOs on the same temperature channel. If there is more than one PRTO, more particles will come out of the ones with lower #s.?

Second Stickman [STK2]

Second stickman. Don't kill him! Control with wasd.

The same as STKM, except has a different name, different controls, and different color legs. Since STK2 uses W and S as controls, you have to hold ctrl to save stamps or change the gravity mode.

Spawned from SPWN2, the only 5 letter long element name. SPWN2 is the same as SPWN, except for STK2.

Tron

Smart particles. Travels win straight lines and avoids obstacles. Grows with time.

Move around the screen and tries to avoid bumping into things. When created, they are a random color. Each "one" consists of a line of same-colored particles, where each one is successively darker. If they reach a dead end and can't turn around, they crash and die.

Black Hole

Black hole. Sucks in particles using gravity (requires Newtonian)

Similar to VAC, except it uses gravity instead of pressure to suck in particles.

White Hole

White hole. pushes other particles using gravity (requires Newtonian Gravity)

similar to vent,except it uses gravity instead of pressure to suck in particles.

Fighter

Fighter. Tries to kill stickmen. You must first give it an element to kill him with.";

Similar to stickman, except not controllable and has a different shaped head. There can also be more than one on the screen at a time. They will follow STKM and SKT2, and try to kill them by shooting particles at them. (they must still pick them up with their head like STK though.)

There is no specific SPAWN element for FIGH, but they can be created with CLNE, etc.
