如何在Libgdx中获得字符串宽度? [英] How get a string width in Libgdx?

问题描述

我想知道如何获得我的字符串的宽度(以像素为单位)

I wonder know how to get the width of my string in pixels

推荐答案

BitmapFont API< 1.5.6

要确保String的宽度，请使用Font并获取String的bounds，您将要绘制.

BitmapFont API < 1.5.6

To mesure the width of a String you use your Font and get the bounds of the String, you are going to draw.

BitmapFont.getBounds(String str).width

BitmapFont API

您也可以为正确的偏移量将高度设置为.只需将宽度替换为高度即可.

You can get the height to for the right offset for drawing too. Just replace width with height.

此外，对于多行文字，请使用getMultiLineBounds(someString).width来获取边界.

In addition for multiline texts use getMultiLineBounds(someString).width to get the bounds.

BitmapFont API在1.5.7中进行了更改，因此现在有另一种获取边界的方法:

The BitmapFont API changed in 1.5.7 so there is a different way to get the bounds now:

BitmapFont.TextBounds和getBounds完成.相反，将字符串提供给GlyphLayout并使用其width和height字段获取界限.然后，您可以通过将相同的GlyphLayout传递给BitmapFont来绘制文本，这意味着这些字形不必像以前那样进行两次布局.

BitmapFont.TextBounds and getBounds are done. Instead, give the string to GlyphLayout and get the bounds using its width and height fields. You can then draw the text by passing the same GlyphLayout to BitmapFont, which means the glyphs don’t have to be laid out twice like they used to.

示例:

GlyphLayout layout = new GlyphLayout(); //dont do this every frame! Store it as member
layout.setText("meow");
float width = layout.width;// contains the width of the current set text
float height = layout.height; // contains the height of the current set text
