LibGDX中的图块无法将java.lang.String转换为java.lang.Boolean

Question

I'm trying to make a function to check if a cell in Tiled can be passed, by accessing a Boolean custom property I gave each tile. This is (part of) my code.

...
public boolean isCellPassable(int column, int row, MapLayer layer) {
    boolean canPass = Boolean.valueOf((Boolean) ((TiledMapTileLayer) layer).getCell(column, row).getTile().getProperties().get("can_pass"));
    if (canPass == true) {
        return true;
    }
    else {
        return false;
    }
}

public void displayHUD(ShapeRenderer hud) {
    System.out.println(isCellPassable(0, 6, Main.level1.getLayers().get("base")));
...

And even though in the isCellPassable function I cast it to a Boolean, for some reason I still get this error ..

Exception in thread "LWJGL Application" java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Boolean

.. on the line where I set the value of canPass .

您可能应该删除对Boolean的Boolean.valueOf(String) ，并确保选择了Boolean.valueOf(String)重载。
