Android使用libgdx实现模拟方向键控制角色移动的方法
本文实例讲述了Android使用libgdx实现模拟方向键控制角色移动的方法。分享给大家供大家参考，具体如下：
packagecom.demo;
importandroid.os.Bundle;
importcom.badlogic.gdx.backends.android.AndroidApplication;
//Libgdx的Texture与Sprite使用
publicclassLibgdxActivityextendsAndroidApplication{
publicvoidonCreate(Bundlebundle){
super.onCreate(bundle);
//初始化游戏屏幕，并设置是否支持GLES2.0，如果您对向下兼容没什么需要选择true即可(2.1以上)，否则选择false。
//initialize(newFirstGame(),true);
initialize(newBox2DDemo(),true);
}
}
packagecom.demo;
importcom.badlogic.gdx.Gdx;
importcom.badlogic.gdx.graphics.Texture;
importcom.badlogic.gdx.graphics.g2d.SpriteBatch;
importcom.badlogic.gdx.scenes.scene2d.Actor;
publicclassFirstActorextendsActor{
privateTexturetexture;
@Override
publicvoiddraw(SpriteBatchbatch,floatarg1){
batch.draw(texture,this.x,this.y);
}
@Override
publicActorhit(floatarg0,floatarg1){
if(x>0&&y>0&&this.height>y&&this.width>x){
returnthis;
}else{
returnnull;
}
}
@Override
publicbooleantouchDown(floatarg0,floatarg1,intarg2){
//TODOAuto-generatedmethodstub
returnfalse;
}
@Override
publicvoidtouchDragged(floatarg0,floatarg1,intarg2){
//TODOAuto-generatedmethodstub
}
@Override
publicvoidtouchUp(floatarg0,floatarg1,intarg2){
//TODOAuto-generatedmethodstub
}
publicFirstActor(Stringname){
super(name);
texture=newTexture(Gdx.files.internal("bt.png"));
this.height=texture.getHeight();
this.width=texture.getWidth();
}
}
