我刚刚开始使用 LibGdx,我已经弄清楚如何使用它来居中文本。现在我在居中对齐文本时遇到了麻烦。我想知道是否有人可以提供帮助。我附上了居中代码。提前谢谢你。
package com.tutorials.game;
import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.BitmapFont;
import com.badlogic.gdx.graphics.g2d.GlyphLayout;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
public class TextDemo extends ApplicationAdapter {
SpriteBatch batch;
BitmapFont font;
String myText;
GlyphLayout layout = new GlyphLayout();
@Override
public void create () {
batch = new SpriteBatch();
font = new BitmapFont(Gdx.files.internal("myFont.fnt"));
myText = "I took one, one cause you left me\n"
+ "Two, two for my family\n"
+ "Three, three for my heartache";
layout.setText(font,myText);
}
@Override
public void render () {
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
float x = Gdx.graphics.getWidth()/2 - layout.width/2;
float y = Gdx.graphics.getHeight()/2 + layout.height/2;
batch.begin();
font.draw(batch,layout,x,y);//Center Text
batch.end();
}
最佳答案
您可以改用以下 setText() 方法并将 targetWidth 设置为屏幕宽度、Aligh.center,并将 wrap 设置为 true。此外,设置 x = 0,使文本在整个屏幕上居中。
import com.badlogic.gdx.graphics.g2d.GlyphLayout;
public void setText(BitmapFont font,
java.lang.CharSequence str,
Color color,
float targetWidth,
int halign,
boolean wrap)
更新示例:
@Override
public void create () {
batch = new SpriteBatch();
font = new BitmapFont(Gdx.files.internal("myFont.fnt"));
myText = "I took one, one cause you left me\n"
+ "Two, two for my family\n"
+ "Three, three for my heartache";
layout.setText(font,myText,Color.BLACK,Gdx.graphics.getWidth(),Align.center,true);
}
@Override
public void render () {
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
float x = 0;
float y = Gdx.graphics.getHeight()/2 + layout.height/2;
batch.begin();
font.draw(batch,layout,x,y);//Center Text
batch.end();
}
