This group contains tools like cooling or heating. Introduced in 59.1 beta.

Heat

Description: "Heats the targeted element."

This tool doesn't produce any particles, but instead raises the ambient temperature of any particles lying beneath the cursor. By sliding the cursor while holding the mouse button, this tool works about four times as fast.

If you hold left mouse button and hold shift, it will heat up particles much faster.

Cool

Description: "Cools the targeted element."

This tool doesn't produce any particles, but instead lowers the ambient temperature of any particles lying beneath the cursor. By sliding the cursor while holding the mouse button, this tool works about four times as fast. It can also can be sped up by holding left click with it equipped and then holding shift.

Air

Description: Air, creates airflow and pressure.

This tool doesn't produce any particles, but rather raises the ambient pressure in the area beneath the cursor. By sliding the cursor around with the mouse button held, you can cause the tool to increase pressure easily four times as fast.

Vacuum

Description: "Vaccum, reduces air pressure."

This tool doesn't produce any particles, but rather lowers the ambient pressure in the area beneath the cursor.

Positive Gravity Tool

Description: "Creates a short-lasting gravity well."

Not an element, click this tool anywhere to increase gravity in the selected area, particles will thus be drawn into that area. Newtonian Gravity must be enabled for it to work. Holding Shift will make the effect stronger, while holding Ctrl will make the effect weaker.

Negative Gravity Tool

Description: "Creates a short-lasting negative gravity well."

Not an element, click this tool anywhere to decrease gravity in the selected area, particles will thus be pushed away from that area. Like PGRV, Newtonian Gravity must be enabled for it to work. Holding Shift will make the effect stronger, while holding Ctrl will make the effect weaker.

Mix Tool

Description: "Mixes particles."

A tool that mixes particles by randomly changing their locations in the area beneath the brush.

Cyclone

Description: "Cyclone, produces swirling air currents."

The swirling effect of this tool can be clearly seen when used on a mixture of gases.

Wind

Description: "Creates air movement."

A Drag tool of sort. It creates pressure/velocity- positive from behind the direction in which you are moving the cursor, and negative in the direction it is moving. This makes it able to "drag" powders and liquids. WIND can also be used to send a strong current of air at a target.

Edit Property Tool

Description: "Property Drawing Tool. Use to alter the properties of elements in the field."

When selected, an input box will instantly appear. The top contains the name of a property such as ctype or temp which is usually edited via console, the bottom box contains a value which will be set. Once you pick a property, click "OK" and then start drawing like a normal brush. Using this you can "paint" on properties. If you want to make CLNE clone DUST you would click it, select ctype on the top and type dust into the bottom. To change the life of DEUT to 1000 you would click the DEUT, type life into the top and 1000 into the bottom.

Sign

Description: "Sign. Displays text. Click on a sign to edit it or anywhere else to place a new one."

Allows you to places signs around your simulation for whatever purpose you need them for. Click on a sign to edit or delete it, or click anywhere else to place a new one.

For linking to other saves, type {c:(Save ID)|(Display text)} to link. For example:

{c:184767|Click here!}

For linking to forum threads, type {t:(Thread ID)|(Display text)} to link. The thread ID is found at the end of the URL for the thread.

For creating clickable button that generate a spark when clicked, type {b|(Display text)}. For example,

{b|Click me!}

For linking to a save search, type {s:(Search Text)|(Display Text)}. For example,

{s:user:jacob1|View my saves!}

If any of these special placeholders are used, they must be the only text in the sign. For instance, the text {b|Click me} to spawn STKM will not work.

There are also placeholders that take readings from the simulation where the sign was placed (where its base points):

• {temp} or {t} shows the temperature of any particle under the sign in degrees Celsius,
• {pres} or {p} shows the pressure under the sign,
• {aheat} or {a} shows the ambient temperature of air under the sign,
• {type} shows the type of any particle under the sign (like in the HUD),
• while {ctype}, {life}, {tmp} and {tmp2} show other particle properties.

For example, this will make the sign show DUST when its base points at DUST:

{type}

Unlike the special kind of placeholders above, these simulation-related ones you can actually combine in any way you like:

This {type} has a temperature of {temp}

... which may result in something along the lines of This Molten BRMT has a temperature of 1302.78.

Sampler

Description: "Sample an element on the screen.""

Element clicked with this tool will be chosen as the element to be drawn from button 1 (left-click). Default action set for mouse button 3 (middle-click).
