LibGdx - 从资产管理器加载json文件时出错

标签： json libgdx

我正在使用assetmanager加载皮肤，并因<table class="table table-bordered"> <?php foreach ($mag->records as $record) : ?> <tr><th style='text-align:center'>ID</th><th style='text-align:center'>DODAŁ</th><th style='text-align:center'>NAZWA</th><th style='text-align:center'>KATEGORIA</th><th style='text-align:center'>SERIAL</th><th style='text-align:center'>ILOŚĆ</th><th style='text-align:center'>DATA</th><th style='text-align:center'>GODZINA</th><th style='text-align:center' colspan='2'>AKCJA</th></tr> <?php $color = NULL; $color1 = '#99bbff'; $color2 = '#b3ccff'; $color == $color1 ? $color = $color2 : $color = $color1; echo "<tr class='active'>"; echo "<td align='center' style='background-color:" . $color . ";'>" . $record['id'] . "</td>"; echo "<td align='center' style='background-color:" . $color . ";'><a href='panel.php?page=userpanel&user=" . $record['added'] . "'>" . $record['added'] . "</a></td>"; echo "<td align='center' style='background-color:" . $color . ";'>" . $record['nazwa'] . "</td>"; echo "<td align='center' style='background-color:" . $color . ";'><a href='panel.php?page=category&cat=" . $record['kategoria'] . "'>" . $record['kategoria'] . "</a></td>"; echo "<td align='center' style='background-color:" . $color . ";'><a href='panel.php?page=editserial&sn=" . $record['sn'] . "'>" . $record['sn'] . "</a></td>"; echo "<td align='center' style='background-color:" . $color . ";'>" . $record['quantity'] . "</td>"; echo "<td align='center' style='background-color:" . $color . ";'>" . $record['data'] . "</td>"; echo "<td align='center' style='background-color:" . $color . ";'>" . $record['godzina'] . "</td>"; echo "<td align='center'><a href='panel.php?page=magazyn&action=edit&sn=" . $record['sn'] . "&nazwa=" . $record['nazwa'] . "&kategoria=" . $record['kategoria'] . "&id=" . $record['id'] . "'</a><button class='btn btn-default'>Edytuj</button></td>"; echo "<td align='center'><a href='panel.php?page=magazyn&action=delete&sn=" . $record['sn'] . "'</a><button class='btn btn-default'>Usuń</button></td>"; echo "</tr>"; endforeach; ?> </table> 而不断收到错误。我试图在我的json文件中使用此字体来创建Label样式。 我在皮肤参数中添加了字体和地图集，我在这里遗漏了什么吗？

我像这样加载我的皮肤：

There is no Bitmapfont registered with name: font_dpb_59

如您所见，我将字体添加为参数，但出现错误。不知道我做错了什么，字体是在皮肤之前加载的。

完整堆栈跟踪：

        ObjectMap<String, Object> font_map = new ObjectMap<String, Object>();
        font_map.put("font_dpb_59", font_dpb_59);
        font_map.put("font_dpm_40", font_dpm_40);
        //... some more fonts

        manager.load(skinAtlas, TextureAtlas.class);
        manager.load(menuSkin, Skin.class, new SkinLoader.SkinParameter(skinAtlas, font_map));

如果这有帮助，这是我的json文件：

编辑：

这是我加载字体的方式：

{
  "com.badlogic.gdx.graphics.Color": {
    "white": {
      "r": 1, "g": 1, "b": 1, "a": 1
    }
  },

  "com.badlogic.gdx.scenes.scene2d.ui.Label$LabelStyle": {
    "font_dpb_59": {
      "font": "font_dpb_59", "fontColor": "white"
    }
  },

  "com.badlogic.gdx.scenes.scene2d.ui.TextButton$TextButtonStyle": {
    "txt_btn_white": {
      "up": "button1",
      "down": "button1",
      "font": "font_dpb_59",
      "fontColor": "white",
      "pressedOffsetX": 1,
      "pressedOffsetY": -1 }
  },

  "com.badlogic.gdx.scenes.scene2d.ui.Button$ButtonStyle": {
    "btn_white": {
      "up": "button1" ,
      "down": "button1",
      "pressedOffsetX": 1,
      "pressedOffsetY": -1 }
  },
  "com.badlogic.gdx.scenes.scene2d.ui.ScrollPane$ScrollPaneStyle": {
    "default": { }
  },

  "com.badlogic.gdx.scenes.scene2d.ui.Window$WindowStyle": {
    "default": { "titleFont": "font_dpb_59", "titleFontColor": "white" }
  }
}

答案 0 :(得分：1)

您在此处传递到ObjectMap的对象：

ObjectMap<String, Object> font_map = new ObjectMap<String, Object>();
font_map.put("font_dpb_59", font_dpb_59);
font_map.put("font_dpm_40", font_dpm_40);

必须是BitmapFont对象，而不是String路径。要拥有BitmapFont实例，您必须已经完成加载一个实例。如果您使用AssetManager加载它们，则必须在资产管理器上调用finishLoading，然后调用get(".....", BitmapFont.class)以获取要放入对象图中的BitmapFont引用。

我原以为你这样做是因为你在运行时使用FreeTypeFontGenerator创建了BitmapFonts，所以无法从Json加载它们。但是，如果您已经提前获得了字体文件，那么您无法直接将它们放入皮肤的Json文件中：

com.badlogic.gdx.graphics.g2d.BitmapFont: {
    font_dpb_59: { file: path/to/font_dpb_59.fnt,
                   scaledSize: 12, //integer height of capital letters
                   markupEnabled: false,
                   flip : false},
}
