我有一个2d布尔arrray，用于映射块的位置（如果坐标为true，则块位于那里）。我试图这样做，如果你点击某处，它将该位置设置为false，因此挖掘该块。我的mapgrid的单元格大小为10，因此如果我点击（200,1000），（20,100）应该在网格中设置为false。以下是我在<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>

InputListener现在这几乎完美无缺，但是y起源仍然是左上角，我以为我正在修复这个我初始化tmp.y的方式，任何帮助都非常感激
答案 0 :(得分：0)
更改tmp.y以在取消投影后更改本地坐标
@Override
public boolean touchDragged(int screenX, int screenY, int pointer) {
tmp.x = screenX;
tmp.y = screenY;
tmp.z = 0;
cam.unproject(tmp);
grid.manipulateGrid((int)(tmp.x) / MapGrid.CELL_SIZE, (int)(tmp.y) / MapGrid.CELL_SIZE, false);
System.out.println("Clicked at: (" + tmp.x / MapGrid.CELL_SIZE + ", " + (Gdx.graphics.getHeight() - tmp.y) / MapGrid.CELL_SIZE +")");
return false;
}
