Operation

Perform a single operation on 2 variables, or just numbers directly, example:

Let’s say a is 10, therefore this operation means 10 + 5
result will then be 15

• +
  Addition

• -
  Subtraction

• *
  Multiplication

• /
  Division

• //
  Integer division, like division but it will round down the results

• %
  Modulo operation, like division but it returns the remainder

• ^
  Power / exponentiation

• Sqrt
  Square root

• ==
  Check if the 2 variables are equal to each other
  Returns 1 or 0 / true or false

• Not
  Logical not, check if the 2 variables are not equal to each other
  Returns 1 or 0 / true or false

• And
  Logical AND gate
  Inputs and output are boolean

• <
  Less than, check if the first variable is less than the second variable
  Returns 1 or 0 / true or false

• >
  Less than equal, check if the first variable is less than equal the second variable
  Returns 1 or 0 / true or false

• >=
  Greater than, check if the first variable is greater than the second variable
  Returns 1 or 0 / true or false

• >=
  Greater than, check if the first variable is greater than the second variable
  Returns 1 or 0 / true or false

• log
  Logarithm, return the exponent given the base and the result

• log 10
  Logarithm in base 10

• abs
  Absolute number

• floor
  Floor , Round down the specified number

• ceil
  Ceiling , Round up the specified number

• or
  Bitwise or

• b-and
  Bitwise and

• XOR
  Bitwise XOR

• flip
  Bitwise flip

• max
  return the largest number out of the 2 number

• min
  return the smallest number out of the 2 number

• angle
  Angle of vector in degrees,usually used like: Angle = ((x1-x2) (y1-y2))
  internally the code does:
  ang1 = atan2(a,b) * 180/π (convert into degrees)
  result = { if ang1 < 0 = (ang1 + 360), otherwise = (ang1) }
  where a is the first variable and b is the second

• angle diff
  Absolute distance between to angles in degrees, usually used like: angdiff = (ang1)(ang2)
  innternally the code does:
  a = a % 360
  b = b % 360
  d1 = (a - b + 360) % 360
  d2 = (b - a + 360) % 360
  result = min(d1, d2)
  where a is the first variable and b is the second

• len
  Length of vector, usually used like: len = ((x1-x2) (y1-y2)).
  internally the code does:
  result = √ (a a + b b)
  where a is the first variable and b is the secondnoise

• noise
  2d simplex
  takes 2 value as coordinates and outputs a value from -1 to 1
  unlike rand, noise is detemernistic, which means a pair of coordinates will always outputs the same result
  for more information to how it internally works check https://github.com/Anuken/Arc/blob/master/arc-core/src/arc/util/noise/Simplex.java the "raw2d" function/method

• rand
  generate a random float in range of 0 to the specified value

• sin
  Sin, in degrees

• cos
  Cos, in degrees

• tan
  Tan, in degrees

• asin
  Asin, in degrees

• atan
  Atan, in degrees

• atan
  Atan, in degrees

Lookup

Look up an item/liquid/unit/block type by ID.
Total counts of each type can be accessed with:
@unitcount / @itemCount / @liquidCount / @blockCount, which is :
56 / 22 / 11 / 254 (as of v146), respectively, they are a constant.
For the inverse operation, sensor @id of the object
Example:

This operation is looking up item with an id of 1, which is lead, thereforeresultwill then be@lead, acontent name, which can be used for things like sensor :

lead_countis now a variable containing number of lead invault1
Lookup are usually used with anincrementing variable
Lists of IDs can be found in theAppendix

Pack Color

Packs RGBA color into a single number, is usually used with draw col and control color
Since it's a single number it can be stored to 1 address on cells/banks, instead of 4 addresses with the usual RGBA, making reading and writing a lot easier too.

RGBA is their respective color, can also be directly written with a number, value is from 0 (dimmest) to 1 (brightest) You can unpack a Packed color by dividing it by %00000001, this will return 32-bit unsigned integer, 8 bits for each value, example : a 255,255,255,255 color when unpacked will return 4294967295, which is the maximum value of 32-bit unsigned integer, converting it to binary will return 11111111111111111111111111111111 ( 8 bit for each value ), by using the bit shift right operation and bitwise and operation you can extract each color value.

Wait

Wait the specified number of seconds, in other words, pausing the processor for that amount of seconds

Stop

Completely stops the processor from running, cannot be resumed in any way other than rebuilding or refreshing the code, to pause a processor disable it instead using control enable

End

End the process, when a processor run this line it will go back to 0 as if it reach the end of the instruction, similar to jump always 0

Jump

Jump to a line number on the processor with a condition
if condition are true jump to the specified line, if false does not jump (continuing to instruction below it

• ==
  Check if the 2 variables are equal to each other

• Not
  Logical not, check if the 2 variables are not equal to each other

• <
  Less than, check if the first variable is less than the second variable

• <=
  Less than equal, check if the first variable is less than equal the second variable

• >
  Less than equal, check if the first variable is less than equal the second variable

• >=
  Greater than equal, check if the first variable is greater than equal the second variable

• ===
  Strict equal, usually used to check for null, example:
  0 null is true, while 0 = null is false

• Always
  Always jump regardless
