Once you have the game up and running, and you have a server up, either through joining someone else's or making your own, you want to start building, right?
Bricks are always in your inventory, unlike Blockland or other games you don't have to select them, they are always there.
The bricks are divided into 10 columns by style and function:
Column one is the building blocks, from 1x1's to 32x32 bases, these are just square bricks.
Column two is regular slopes, these are a collection of sloping downward bricks.
Column three is inverted slopes, which are mostly the same as column two, except slope up instead.
Column four is arches, and contains a lot of different sizes and styles.
Column five is windows, allsorts.
Column six is wings and variated plane & boat parts.
There are hulls for boat building, as well as the traditional wings from lego planes. Also cones.
Column seven is Miscellanea #1, it contains things that range from grills, to flagpoles and transparent bricks.
Column eight is Miscellanea #2, and contains the same stuff, and castle wall bricks and spaceship parts.
Column nine is decals, and works in conjunction with alt+D, the decal menu. More on how to use these later.
Column ten is bases and roads, and is just a collection of things to build on.
These brick columns are accessible through the 1-10 keys above your a-z keys. Note that this is NOT the number pad.
Brick Columns can be cycled through by hitting the corresponding brick column's number repeatedly, or by selecting the column with its number and then using the scroll wheel to browse.
Once you have found your brick, click in the direction of a baseplate to put down the placing tool.
This shows where you will put your brick, and can be manipulated before placing using the Number Pad on the right of your keyboard. Laptop users will need to configure this (use alt+o, controls, keyboard mapping). Bricks can be anchored and placed permanently with the Enter button.
To paint bricks, you must use the "Q" button. This brings up the spraycan.
By default it is set to a boring grey, but this can be changed by hitting alt+Q, which brings up the paint palette.
To delete bricks placed, you can use the "Z" key, which brings up a hammer, or the edit staff (E key). More on the edit staff later.
