Wurst goes 1.29 and beyond

As the new patch has hit earlier in April, we have implemented the necessary changes to support it in our toolchain, while still keeping backwards compatibility alive.

Increased maximum class instances to 32768 to match new array sizes in 1.29+

to 32768 to match new array sizes in 1.29+ The new common.j and blizzard.j are now supplied by default

are now supplied by default Implemented vararg function parameters - functions that take a variable amount of parameters of a certain type.

- functions that take a variable amount of parameters of a certain type. VSCode highlighting has been improved to match the language documentation, recognizing punctuation and operators

has been improved to match the language documentation, recognizing punctuation and operators Deprecation warnings now also show for variables

Fixed two unusual exceptions related to extended unicode characters

Implemented additional natives for compiletime such as timers, triggers, rects and more, enabling those to be used in unit tests.

Modified standard units get printed into WurstExportedObjects again, for easier transfer to generated objects

again, for easier transfer to generated objects The operator precedence of or in Wursts Jass parsing is now correct

Standard Library

Merged over 10 awesome pull requests regarding object editing, damage detection and the new Blz natives

regarding object editing, damage detection and the new Blz natives Extension function wrappers for the new natives, such as effect.setColor and item.setName have been added

and have been added Packages affected by the new 24 player capability, such as Colors , have been updated accordingly

, have been updated accordingly Fixed and unit tested several issues with typecasting and error handling

Variable Argument Functions

Wurst now supports a limited variant of variable argument functions. Variable arguments can only be iterated over and not directly accessed, neither the amount.

Declaration:

function sum(vararg int ints) var result = 0 for i in ints result += i print(result.toString())

Usage:

sum(1,2,3,4) sum(14,22) sum(23,52,5234,5,5)

Several functions in the standard library are now implemented via varargs, and as such, offer variable argument functionality, for example id-lists for object editing and groups:

@compiletime function genBuilder() new UnitObjDefinition('buil', 'hfoo') ..setNormalAbilities(asList(ID_FIREBALL, ID_FIRE_NOVA)) ..setStructuresBuilt(asList(ID_GUARD_TOWER, ID_CANNON_TOWER)) init CreateGroup().addUnit(u1, u2, u3)

Additionally asList is now available to inline create LinkedLists of elements

asList("This", "will", "be", "a", "list") asList(75., 125., 175.).add(250., 375.) asList(players[0], players[1], players[2], players[3])

Protips

Want to be most efficient with wurst? Under the ‘Protip’ slogan we will regularly feature ways or products to improve your workflow:

Use Vector Tuples Instead of working with either locations, which leak and shouldn’t be used, or x and y coordinates, which doubles the amount of code you have to write and the amount of mistakes you can make, Wurst provides vec2 and vec3 vector tuples which, unlike classes, don’t have an identity and therefore are translated with zero overhead. This means you get the speed of using coordinates directly, but the comfort of class-like syntax and functionality.

Some common uses:

// Event response getSpellTargetPos() // instead of GetSpellTargetX/Y getOrderPos() // instead of GetOrderPointX/Y getOrderTargetPos() // instead of GetWidgetX(GetOrderTarget()) etc. // As class member, e.g. position, velocity class A vec2 position // Angle between points & Polar projection function onEvent() let casterPos = GetTriggerUnit().getPos() let angl = casterPos.angleTo(getSpellTargetPos()) flashEffect(Objects.impaleTargetDust, casterPos.polarOffset(angl, 256.))

You will notice that many extension functions also expect vector tuples as arguments, making them even more seamless to use.

VSCode extension: vscode-icons Adds meaningful icons to the folder tree view, improving visual recognition and fidelity. Wurst code files don’t get recognized yet, but most other files do, which helps to distinguish them.
