NetLogo LevelSpace报错：已执行reset-ticks仍提示未启动滴答计数器

正在学习使用NetLogo的LevelSpace扩展，被调用的FlockingModified.nlogo本身无任何错误，现有三段代码分别存在以下问题：

1. A段代码问题 #

能运行但无法改变id_world，达不到预期效果：

to setup
    ls:reset
    ca
    ls:create-interactive-models number_worlds "FlockingModified.nlogo"
    ls:ask ls:models [ setup ]
    reset-ticks
end

to go
    clear-all
    ls:ask ls:models [ go ]
    let number_centroids [count centroids] ls:of ls:models
    let x_centroids [ListXCentroids] ls:of ls:models
    let y_centroids [ListYCentroids] ls:of ls:models
    let heading_centroids [ListHeadingCentroids] ls:of ls:models
  
    foreach ls:models[
        i -> let id_world i
        let number_centroid item id_world number_centroids
        let xcoords item id_world x_centroids
        let ycoords item id_world y_centroids
        let headings item id_world heading_centroids
        loop [
            if number_centroid = 0 [stop]
            create-turtles 1 [
                set color 15 + 10 * id_world
                setxy last xcoords last ycoords
                set heading last headings
        ]
        ;this is a home made pop, equivalent to java pop
        set xcoords but-last xcoords
        set ycoords but-last ycoords
        set headings but-last headings
        set number_centroid number_centroid - 1
    ]
    
    tick
end

2. loop版本代码问题 #

无法执行到set models but-last models语句：

loop[
    if empty? models [stop]
    let id_world last models
    let number_centroid item id_world number_centroids
    let xcoords item id_world x_centroids
    let ycoords item id_world y_centroids
    let headings item id_world heading_centroids
    loop [
        if number_centroid = 0 [stop]
        create-turtles 1 [
            set color 15 + 10 * id_world
            last xcoords last ycoords
            set heading last headings
        ]
        ;this is a home made pop, equivalent to java pop
        set xcoords but-last xcoords
        set ycoords but-last ycoords
        set headings but-last headings
        set number_centroid number_centroid - 1
    ]
    ;;it never gets to here
    set models but-last models
]

3. while版本代码问题 #

功能符合预期，但仅在首次tick后抛出错误：

The tick counter has not been started yet. Use RESET-TICKS. error while observer running TICK called by procedure GO called by Button 'go'

代码：

let models ls:models
while [not empty? models] [
    let id_world last models
    let number_centroid item id_world number_centroids
    let xcoords item id_world x_centroids
    let ycoords item id_world y_centroids
    let headings item id_world heading_centroids
    while[number_centroid > 0] [
        create-turtles 1 [
            set color 15 + 10 * id_world
            setxy last xcoords last ycoords
            set heading last headings
        ]
        ;this is a home made pop, equivalent to java pop
        set xcoords but-last xcoords
        set ycoords but-last ycoords
        set headings but-last headings
        set number_centroid number_centroid - 1
    ]
    set models but-last models
]
