libgdx 如何缩放 BitmapFont 以更改屏幕尺寸?

问题描述

我想要的是在更改屏幕尺寸时相应地更改大小的位图字体.我的意思是在我的电脑上，字体看起来相当大，但在我的手机上，它是一种难以阅读的小字体.我可以更改大小，但我希望它在所有屏幕上看起来都相似，而不是在一个屏幕上大而在另一个屏幕上小.这是我的代码，看看我必须使用什么:

What I want to have is the Bitmap Font to change in size accordingly when changing screen sizes. What I mean is on my computer, the font appears rather large, but on my phone, it is a little font that is harder to read. I could change the size, but I want it to look similar on all screens, instead of having it large on one screen and smaller on another. Here is my code to see what I have to work with:

public void render() {
    //score system
    scoreFont.setColor(1.0f, 1.0f, 1.0f, 1.0f);
    scoreBatch.begin(); 
    scoreFont.draw(scoreBatch, Long.toString(getScore()), 10, Gdx.graphics.getHeight() - 10); 
    scoreFont.setScale(3, 3);
    scoreBatch.end();
}

public void resize(int width, int height) {
    camera.viewportWidth = 450;
    camera.viewportHeight = 250;
    camera.update();
    stage.setViewport(450, 250, true);
    stage.getCamera().translate(-stage.getGutterWidth(), -stage.getGutterHeight(), 0);
}

推荐答案

这样想，你总是希望有相同的比例.

Think of it this way, you always want to have the same ratio.

例如:

500/3 = 450/x

500/3 = 450/x

x 是文本的新大小.所以你必须做一些交叉乘法.

x is the new size of your text. So you have to do some cross multiplying.

500x = 1350

500x = 1350

1350÷500 = x

1350÷500 = x

所以现在以编程方式执行此操作.

So now to do this programmatically.

public void resizeText(float width, float currentSize, float currentWidth){
    //currentWidth/currentSize = width/x
    a = width * currentSize;//450 * 3 in example above
    b = a/currentWidth;
    return b;//returns the x or the new size that your text should be
}

你还说它需要根据大小超过一定数量而改变.

Also you said that it needs to change depending on of the size is over a certain amount.

所以这是我设计的一个小东西

So here's a little thing I've devised

ApplicationType appType = Gdx.app.getType();
   if (appType == ApplicationType.Android || appType == ApplicationType.iOS) {
        screenFont.setScale(your number)
    } else { screen font.setScale(otherNum)} //if its a desktop
