所以我有一个叫做Cell的类,我想创建一个Cell的对象矩阵,但是我陷入了困境,这就是我到目前为止所获得的,并且它无法正常工作
如何正确执行此操作?谢谢
class GameView(context: Context?, attrs: AttributeSet?) :
View(context, attrs) {
private val COLS:Int = 7
private val ROWS: Int = 10
fun createMaze(){
//this gives me an error Type inference failed. Expected type
//mismatch:
//required:
//Array<Array<Cell>>
//found:
//Array<IntArray>
var cells: Array<Array<Cell>> = Array(COLS, {IntArray(ROWS)})
for(x in 0..COLS){
for(y in 0..ROWS){
cells[x][y] = Cell(x,y)
}
}
}
}
class Cell(var col:Int, var row: Int){
var topWall = true
var leftWall = true
var bottomWall = true
var rightWall = true
}
答案 0 :(得分:1)
您将单元格类型定义为Array<Array<Cell>>
,但初始化为Array<IntArry>
我认为只有很小的变化:
class Cell(var col:Int=0, var row: Int=0){
var topWall = true
var leftWall = true
var bottomWall = true
var rightWall = true
}
var cells: Array<Array<Cell>> = Array(COLS, {Array<Cell>(ROWS, {Cell()})})
