Introduction
Pattern scripts is special kind of expressions that returns 1 or 0.
Pattern scripts are used to determine availability of some functionality or event, checks for special conditions.
Pattern scripts can check for very wide range of conditions (gametime, special parms of entities, infoportions etc.).
Example of things controlled by pattern scripts:
- Enemy appearance (some enemies are only active at night, some only at day etc.)
- Gamemodels damage masks (checks if could be damaged by certain weapon)
- Checking if trigger could be touched
Example of how pattern script looks like:
// this script check if its a night or if there is an enemy within 300 units night | enemy<300>.found
// this scripts check if gametime is between 12 and 14 hours hour =><= 12 14
// this script check if it's fullmoon night or raining (night & fullmoon) | raining

| 1 | ( ) | ( expression ) | Expression |
| 2 | & | x & y | Logical 'And' |

| 4 | = | x = y | Equal |
| 5 | != | x != y | Not equal |
| 6 | > | x > y | Greater |
| 7 | >= | x >= y | Greater or equal |
| 8 | < | x < y | Lesser |
| 9 | <= | x <= y | Lesser or equal |
| 10 | not | x & not y | Logical Not |
| 11 | >< | x >< start end | x > start And x < end |
| 12 | =>< | x =>< start end | x >= start And x < end |
| 13 | ><= | x ><= start end | x > start And x <= end |
| 14 | =><= | x =><= start end | x >= start And x <= end |
Functions
