我正在尝试使用andengine library
进行游戏。
当Sprite Enemy1Sprite
到达相机顶部时,我将其分离,抛出此异常:
java.lang.IndexOutOfBoundsException Invalid Index 12 size is 12
我必须分离
enemy1Sprite
,因为它会不断在相机外产生子弹。这是代码。
等级敌人1:
package es.uah.juegomentos;
import org.anddev.andengine.engine.handler.timer.ITimerCallback;
import org.anddev.andengine.engine.handler.timer.TimerHandler;
import org.anddev.andengine.entity.sprite.Sprite;
import org.anddev.andengine.opengl.texture.region.TextureRegion;
public class Enemy1 extends Sprite {
boolean abajo = true;
public Enemy1(TextureRegion pTextureRegion) {
super(0, 0, pTextureRegion);
this.setPosition(JuegoMentosActivity.RANDOM.nextInt(JuegoMentosActivity.CAMERA_WIDTH), -10);
TimerHandler Enemy1fire = new TimerHandler(0.75f, true, enemigo1fireCallback);
JuegoMentosActivity.getmGameScene().registerUpdateHandler(Enemy1fire);
}
@Override
protected void onManagedUpdate(float pSecondsElapsed) {
super.onManagedUpdate(pSecondsElapsed);
float y = getY();
if (y >= 275) {abajo = false;}
if (abajo) {y = y + pSecondsElapsed * 125.0f;}
else {y = y - pSecondsElapsed * 125.0f;}
this.setPosition(getX(), y);
if (getY()<-10){this.getParent().detachChild(this);}
}
ITimerCallback enemigo1fireCallback = new ITimerCallback(){
@Override
public void onTimePassed(TimerHandler pTimerHandler) {
bala1 mbala1;
mbala1 = new bala1(getX()+(64*1/2),getY()+64,JuegoMentosActivity.getMbala1Texture().getTextureRegion(),true);
JuegoMentosActivity.getmGameScene().attachChild(mbala1);
}
};
}
在现场创建新敌人:
//Creamos el sprite del enemigo uno
ITimerCallback enemigo1CreatorCallback = new ITimerCallback(){
@Override
public void onTimePassed(TimerHandler pTimerHandler) {
mEnemy1Sprite = new Enemy1(mEnemy1Texture.getTextureRegion());
mGameScene.attachChild(mEnemy1Sprite);
}
};
TimerHandler Enemy1Creator = new TimerHandler(3.0f, true, enemigo1CreatorCallback);
mGameScene.registerUpdateHandler(Enemy1Creator);
谢谢
最佳答案
您确实回答了自己的问题-Marcelo是正确的,问题不在发布的代码中,而是您在进行detachChild的地方-您需要在Update Thread上进行调用,例如
runOnUpdateThread(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
yourScene.detachChild(yourEnemySprite);
}
});
