PointList.setMany

An example of switching the rotation value in all points in a list, selecting the last row and using setMany:

Example before

pointList.forEach((p,i)=>{
    p.radius = conf.radius
    let isLastColumn = (i+1) % conf.cols == 0;
    let dir = isLastColumn? DOWN_DEG: RIGHT_DEG
    p.rotation =  dir
})

setMany

pointList.setMany(conf.radius, 'radius')
pointList.setMany(RIGHT_DEG, 'rotation')
pointList.setMany(false, 'hit')

let gridTools = new GridTools(pointList, 10) // 10 columns wide
let columnPointList = gridTools.getColumn(-1) // get the last column

columnPointList.setMany(DOWN_DEG, 'rotation')

setDict

pointList.setData({
    radius: conf.radius
    , rotation: RIGHT_DEG
    , hit: false
})


let gridTools = new GridTools(pointList, 10) // 10 columns wide
let columnPointList = gridTools.getColumn(-1) // get the last column

columnPointList.setMany(DOWN_DEG, 'rotation')
