(libgdx小结)常见UI的使用
以下主要介绍的是Label、Image、Button的使用，用法比较固定
直接贴代码
Label
package com.example.groupactiontest;
import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.Color;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.g2d.BitmapFont;
import com.badlogic.gdx.scenes.scene2d.Stage;
import com.badlogic.gdx.scenes.scene2d.ui.Label;
import com.badlogic.gdx.scenes.scene2d.ui.Label.LabelStyle;
public class MyGame implements ApplicationListener {
Stage stage;
@Override
public void create() {
stage = new Stage();
//创建一个label
BitmapFont font = new BitmapFont(Gdx.files.internal("jd.fnt"),Gdx.files.internal("jd.png"),false);
LabelStyle style = new LabelStyle(font,font.getColor());
Label label = new Label("Hello Libgdx ", style);//第一个参数为label中的字体,第二个为label的style
label.setPosition(50 , 150);
label.setColor(Color.GREEN);
stage.addActor(label);
Gdx.input.setInputProcessor(stage);
}
@Override
public void dispose() {
}
@Override
public void pause() {
}
@Override
public void render() {
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
stage.act();
stage.draw();
}
@Override
public void resize(int arg0, int arg1) {
}
@Override
public void resume() {
}
}
Image
package com.example.groupactiontest;
import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.Color;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.TextureRegion;
import com.badlogic.gdx.scenes.scene2d.Stage;
import com.badlogic.gdx.scenes.scene2d.ui.Image;
public class MyGame implements ApplicationListener {
Stage stage;
Image image;
TextureRegion region;
Texture texture;
@Override
public void create() {
stage = new Stage();
texture = new Texture(Gdx.files.internal("potato.jpg"));
region = new TextureRegion(texture,512,0,512,512);
image = new Image(region);
image.setSize(480, 320);
image.setColor(Color.GREEN);
image.setPosition(0,0);
image.setOrigin(0, 0);
image.setRotation(45f);
stage.addActor(image);
}
@Override
public void dispose() {
// TODO Auto-generated method stub
}
@Override
public void pause() {
// TODO Auto-generated method stub
}
@Override
public void render() {
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
stage.act();
stage.draw();
}
@Override
public void resize(int arg0, int arg1) {
// TODO Auto-generated method stub
}
@Override
public void resume() {
// TODO Auto-generated method stub
}
}
Button
package com.example.groupactiontest;
import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.TextureRegion;
import com.badlogic.gdx.scenes.scene2d.Stage;
import com.badlogic.gdx.scenes.scene2d.ui.Button;
import com.badlogic.gdx.scenes.scene2d.ui.ImageButton;
import com.badlogic.gdx.scenes.scene2d.utils.TextureRegionDrawable;
public class MyGame implements ApplicationListener {
Stage stage;
Texture texture;
TextureRegion buttonUp;
TextureRegion buttonDown;
TextureRegionDrawable up;
TextureRegionDrawable down;
Button button;
@Override
public void create() {
stage = new Stage();
texture = new Texture(Gdx.files.internal("button.png"));
buttonUp = new TextureRegion(texture, 0, 0,120,120);
buttonDown = new TextureRegion(texture,120,0,120,120);
up = new TextureRegionDrawable(buttonUp);
down = new TextureRegionDrawable(buttonDown);
button = new ImageButton(up, down);
stage.addActor(button);
Gdx.input.setInputProcessor(stage);
}
@Override
public void dispose() {
// TODO Auto-generated method stub
}
@Override
public void pause() {
// TODO Auto-generated method stub
}
@Override
public void render() {
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
stage.act();
stage.draw();
}
@Override
public void resize(int arg0, int arg1) {
// TODO Auto-generated method stub
}
@Override
public void resume() {
// TODO Auto-generated method stub
}
}
