以编程方式更改字体时，Libgdx外观未更新 [英] Libgdx Skin not Updating when Changing Font Programmatically
问题描述
首先，我将皮肤作为json文件加载.在文件中，我放置了两个BitmapFont定义(字体"和大字体")，并将它们实际上留为空白(我确实加载了一个虚拟的".fnt"文件以防止解析器抱怨).然后，我使用以下代码生成了两种FreeType字体:
First, I loaded the skin as a json file. In the file, I put two BitmapFont defintions ("font" and "big-font") and left them practically blank (I did load a dummy ".fnt" file to prevent the parser from complaining). I then generated two FreeType Fonts using the following code:
//start font generator
FreeTypeFontGenerator generator = new FreeTypeFontGenerator(Gdx.files.internal("fonts/button-font.ttf"));
FreeTypeFontGenerator.FreeTypeFontParameter parameters = new FreeTypeFontGenerator.FreeTypeFontParameter();
//default font (the sizes are arbitrary, since it did not work...)
parameters.size = 10;
BitmapFont defaultFont = generator.generateFont(parameters);
//big font
parameters.size = 100;
BitmapFont bigFont = generator.generateFont(parameters);
并将它们设置为皮肤字体，如下所示:
And set them as the skin fonts like so:
skin.add("font", defaultFont, BitmapFont.class);
skin.add("big-font", bigFont, BitmapFont.class);
问题在于gui(尤其是使用"font"字体的TextButton)似乎并不关心我以编程方式所做的事情，而是继续使用在json文件中设置的虚拟字体.
The problem is that the gui (particularly the TextButton, which uses the "font" font) does not seem to care about what I did programmatically and keeps using the dummy font that I've set in the json file.
我做错了什么?有没有更好的方法来集成ttf字体和json皮肤解析?
What am I doing wrong? Is there a better way to integrate ttf fonts and json skin parsing?
在此先感谢您的帮助.
推荐答案
请按照以下步骤操作:
-
首先，从TTF文件创建字体
First, create your font from a TTF file
FreeTypeFontGenerator generator = new FreeTypeFontGenerator(Gdx.files.internal("fonts/button-font.ttf"));
FreeTypeFontParameter parameter = new FreeTypeFontParameter();
parameter.size = 10;
BitmapFont defaultFont = generator.generateFont(parameter);
generator.dispose(); // don't forget to dispose to avoid memory leaks!
使用默认构造函数创建空白外观并将字体添加到外观中.
Create a blank skin using default constructor and add your font to the skin.
Skin skin = new Skin();
skin.add("font",defaultFont);
将地图集文件添加到皮肤.
Add your atlas file to your skin.
skin.addRegion(new TextureAtlas(Gdx.files.internal("mySkin.atlas")));
将您的Json文件加载到皮肤上.
Load your Json file to your skin.
skin.load(Gdx.files.internal("mySkin.json"));
然后，在您的JSON文件中，您可以引用字体"
then, in your JSON file you can reference "font"
{
font: font
}
