Android неправильное поведение обнаружения столкновений с движущимися видами

Question

Привет android Инженеры У меня проблема с моей игрой android. Игра состоит в том, чтобы иметь элементы управления xbox, которые выбирают / перемещают объекты на экране. Идея состоит в том, чтобы перемещать изображение указателя на экране, пока оно не включится. Затем мой нужный объект нажмите некоторую кнопку выбора "x", чтобы перетащить этот объект с изображением указателя и поместить его (мой объект) в указанное c место

его перетаскивание, но с помощью элементов управления не трогайте

проблема в том, что столкновение не работает правильно для всех объектов .. фактически работает для 2 или 3, затем не работает

я использовал следующий код для перемещения изображения указателя

 private fun functionUp() {

    val paramsTop = cursorLayout.layoutParams as RelativeLayout.LayoutParams
    paramsTop.bottomMargin += 60
    cursorLayout.layoutParams = paramsTop
    cursorLayout.invalidate()
    getXY(cursorLayout)
}

private fun functionDown() {
    val paramsBottom = cursorLayout.layoutParams as RelativeLayout.LayoutParams
    paramsBottom.bottomMargin -= 60
    cursorLayout.layoutParams = paramsBottom
    cursorLayout.invalidate()
}

private fun functionLeft() {
    val paramsLeft = cursorLayout.layoutParams as RelativeLayout.LayoutParams
    paramsLeft.leftMargin -= 60
    cursorLayout.layoutParams = paramsLeft
    cursorLayout.invalidate()
}

private fun functionRight() {
    val paramsRight = cursorLayout.layoutParams as RelativeLayout.LayoutParams
    paramsRight.leftMargin += 60
    cursorLayout.layoutParams = paramsRight
    cursorLayout.invalidate()
}

и для обнаружения столкновений

 private fun checkCollision(v1: View, v2: View): Boolean {
    val R1 = Rect(v1.left, v1.top, v1.right, v1.bottom)
    val R2 = Rect(v2.left, v2.top, v2.right, v2.bottom)
    return R1.intersect(R2)
}

и проверки на столкновение

private fun functionSelect() {
        when {
            checkCollision(cursor, wordOne) -> {
                wordOne.backgroundTintList =
                    ContextCompat.getColorStateList(requireContext(), R.color.terquaz)
                if (wordOne.parent != null)
                    (wordOne.parent as ViewGroup).removeView(wordOne)
                cursorLayout.addView(wordOne)
            }
            checkCollision(cursor, wordTwo) -> {
                wordTwo.backgroundTintList =
                    ContextCompat.getColorStateList(requireContext(), R.color.terquaz)
                if (wordTwo.parent != null)
                    (wordTwo.parent as ViewGroup).removeView(wordTwo)
                cursorLayout.addView(wordTwo)
            }
            checkCollision(cursor, wordThree) -> {
                wordThree.backgroundTintList =
                    ContextCompat.getColorStateList(requireContext(), R.color.terquaz)
                if (wordThree.parent != null)
                    (wordThree.parent as ViewGroup).removeView(wordThree)
                cursorLayout.addView(wordThree)

            }
            checkCollision(cursor, wordFour) -> {
                wordFour.backgroundTintList =
                    ContextCompat.getColorStateList(requireContext(), R.color.terquaz)
                if (wordFour.parent != null)
                    (wordFour.parent as ViewGroup).removeView(wordFour)
                cursorLayout.addView(wordFour)
            }
            checkCollision(cursor, wordFive) -> {
                wordFive.backgroundTintList =
                    ContextCompat.getColorStateList(requireContext(), R.color.terquaz)
                if (wordFive.parent != null)
                    (wordFive.parent as ViewGroup).removeView(wordFive)
                cursorLayout.addView(wordFive)
            }

Answer 1

Я выяснил проблему ... это было в методе обнаружения столкновений в android, поэтому gitHitRecArea не работал, если представления не в том же макете (и это мое предположение), но когда я использовал view.getGlobalVisibleRect, тогда rect1.intersect(rect2)

это работает как шарм !!

только что опубликовал его на случай, если кто-нибудь столкнется с такой же проблемой
