Introduction
Pattern scripts is special kind of expressions that returns 1 or 0 used to determine availability of some functionality or event. This scripts can check for very wide range of conditions (gametime, special parms of entities, infoportions etc.).
Usage examples:
- 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
Basic syntax:
// 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
Operators
| # | Operator | Example | Description |
|---|---|---|---|
| 1 | ( ) | ( expression ) | Expression |
| 2 | & | x & y | Logical 'And' |
| 3 | | | x | y | Logical 'Or' |
| 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
Set of functions is determined by pattern implementation. There is two pattern implementations as of yet.
GenericPattern
This is generic appearance pattern. It used on enemies appearance, zone appearance.
| # | Operator | Description |
|---|---|---|
| true | Always returns 1 | |
| false | Always returns 0 | |
| entity.field | ||
| target<name>.field | ||
| enemy<radius>.field | ||
| sid<name>.field |
GamemodelHitPattern
| # | Operator | Description |
|---|---|---|
| true | Always returns 1 | |
| false | Always returns 0 | |
| pushonly | System word. Allows to push object but not destroy. This should be the first operator in expression if used. | |
| tag_tagname | Returns 1 if model tag closest to hit position matches this tag. Otherwise 0. | |
