Bit

Overview

Lots of things in SimAntics are represented by bit flags. If you are a programmer you may already be familiar with adding up bit numbers, if you are not, this page is for you! Think of bits like switches. If switch number 1 (bit 1) is turned on then a certain thing happens. Several switches can be on at once whilst others are off.

Example

Bit number 1 when set gives a value 0x01.
Bit number 2 when set gives a value 0x02.
Bit number 3 when set gives a value 0x04.

Turning on bits number 1 and 3 gives a value 0x05.

Turning on any bit twice doesn't change the value. The switch is on, it can't be on any more.
