sandbox

This is a simple sandbox simulation program. It has 5 materials: Stone, Sand, Water, Steam, and lava. Each of these materials acts differently.    

These objects are placed with the left click. The materials can be accessed by pressing the number keys: 1 being stone, 2 being sand, 3 being water, 4 being lava and 5 being steam. Or is accessible with a middle click, where you can hover over the partial that has the type you want and press the middle click.

The materials can all be deleted with the right click or some hotkeys. Say you want only to delete one type of material, you have to press the letter that is underneath the number of the material you want to delete, E.g. Q will delete stone, and W will delete sand. You can clear everything by pressing A.

Material	Properties	Appearance	Hotkeys
Stone	Stone is a stationary block, it can't be moved and nothing can go through it.		place: 1 delete: q
Sand	Sand is a powder that can go through anything but stone, it piles up onto of each other, making a triangle-shaped object on a flat plain.		place: 2 delete: w
Water	Water is a liquid that turns into steam when it comes in contact with lava.		place: 3 delete: e
Lava	Lava moves just like water and turns into stone in contact with water.	#ff9619	place: 4 delete: r
Steam	Steam is a gas like particle that acts like water, but it floats. It also turns into water in contact with water.	#e6e6e6	place: 5 delete: t

Some additional hotkeys activate different options

Hot Key	Effect of the press
P	Pauses the games until pressed again.
C	Enables smart-mapping, that will turn on or off the update mapping depending on the situation.
V	Turns on or off the FPS counter, in the top left corner.
B	Shows all the updates that are happening on every tick, displayed with a magenta overlay.
N	Updates the whole box, in case the update mapping fails.
M	Enables or disables update mapping, if the smart-mapping is turned off.
S	Enables or disables solid walls.

Please Note: This simulation can get some what laggy, with too much particles on the screen.
