Compile REPEAT

REPEAT is a compile-time loop that can be used to generate code. It is useful for generating repetitive code, like scoreboard trees, and for generating code based on arrays and iterators.

REPEAT has several different forms, depending on the type of loop you want to create.

Integer Range

Repeats the code from min to max inclusive. Incrementing by 1 or -1 based on the provided range.

If as is provided, the variable will be assigned to the current value of the loop.

REPEAT (min:int, max:int) [as <variable name>] {
    <...>
}
Examples

Basic

Code
REPEAT (1, 3) {
    say Hello, world!
}
Output
say Hello, world!
say Hello, world!
say Hello, world!

With as

Code
REPEAT (1, 3) as i {
    say Loop <%i%>
}
Output
say Loop 1
say Loop 2
say Loop 3

Float Range

Repeats the code from min to max inclusive. Incrementing by increment.

If as is provided, the variable will be assigned to the current value of the loop.

REPEAT (min:float, max:float, increment:float) [as <variable name>] {
    <...>
}
Examples

Basic

Code
REPEAT (0, 1.5, 0.5) {
    say Hello, world!
}
Output
say Hello, world!
say Hello, world!
say Hello, world!
say Hello, world!

With as

Code
REPEAT (0, 1.5, 0.5) as i {
    say Loop <%i%>
}
Output
say Loop 0
say Loop 0.5
say Loop 1.0
say Loop 1.5

JS Array

Repeats the code for each value in the provided array.

If as is provided, the variable will be assigned to the current value of the loop.

REPEAT (array:Array) [as <variable name>] {
    <...>
}
Examples

Basic

Code
REPEAT ([1,2,7,9]) {
    say Hello, world!
}
Output
say Hello, world!
say Hello, world!
say Hello, world!
say Hello, world!

With as

Code
REPEAT ([1,2,7,9]) as i {
    say Looped <%i%>
}
Output
say Looped 1
say Looped 2
say Looped 7
say Looped 9

JS Iterator

Repeats the code for each value in the provided iterator.

If as is provided, the variable will be assigned to the current value of the loop.

REPEAT (iterator:() => Iterator) [as <variable name>] {
    <...>
}
Examples

Basic

Code
REPEAT (store.iterator) {
    say Hello, world!
}
Output
say Hello, world!
say Hello, world!
say Hello, world!
say Hello, world!

With as

Code
REPEAT (function*() { yield 1; yield 2; yield 7; yield 9; }) as i {
    say Looped <%i%>
}
Output
say Looped 1
say Looped 2
say Looped 7
say Looped 9

Object Desctructuring

Repeats the code for each key, value pair in the provided object.

REPEAT (<object>) [as <variable name>, <variable name>] {
    <...>
}
Examples
Code
REPEAT ({a: 1, b: 2, c: 7, d: 9}) as key, value {
    say <%key%> = <%value%>
}
Output
say a = 1
say b = 2
say c = 7
say d = 9
