我在AndEngine中开发我几乎完成了我的游戏，但不幸的是，由于我在更新循环中检查.collides很多，偶尔会遇到低fps。我现在明白，这是问题所在，我一直试图用Box2d来改变它与理论上的物体，这正是我所需要的，但我无法抓住它！Box2d碰撞检测与阵列
基本上，我有4个数组;一个是汽车，三个是敌人。汽车从左到右驾驶，如果他们与这些敌人中的任何一个接触，则速度会有所不同。当我加载阵列时，是否必须为每辆汽车和敌人分配车身？然后我该如何检查？我是否运行for循环，然后运行isBodyContacted（carBody，iceBergBody）;'在更新中看？这有点合作！
仅供参考，装我的车：
private void loadCar() {
for (int i = 0; i < rManager.getInstance().carArray.length; i++) {
rManager.getInstance().carArray[i] = new Car(new Sprite(
rManager.getInstance().spawnPoint[i].getSpawnPos().x,
rManager.getInstance().spawnPoint[i].getSpawnPos().y,
rManager.getInstance().car_region,
engine.getVertexBufferObjectManager()) {
@Override
public boolean onAreaTouched(final TouchEvent pSceneTouchEvent,
final float pTouchAreaLocalX,
final float pTouchAreaLocalY) {
if (pSceneTouchEvent.isActionMove()
&& GameManager.getInstance().getDebugMode() == true) {
this.setPosition(pSceneTouchEvent.getX(),
pSceneTouchEvent.getY());
}
return true;
}
});
}
for (int i = 0; i < rManager.getInstance().carArray.length; i++) {
rManager.getInstance().carArray[i].getCarSprite().setScale(0.5f);
rManager.getInstance().carArray[i].getCarSprite().setAnchorCenter(
0, 0);
colourX = (randNumber(2, 9));
colourY = (randNumber(2, 9));
colourZ = (randNumber(2, 9));
colourX /= 10;
colourY /= 10;
colourZ /= 10;
rManager.getInstance().carArray[i].getCarSprite().setColor(colourZ,
colourY, colourZ);
attachChild(rManager.getInstance().carArray[i].getCarSprite());
this.registerTouchArea(rManager.getInstance().carArray[i]
.getCarSprite());
this.setTouchAreaBindingOnActionDownEnabled(true);
}
}
加载一个敌人..
void loadIceBerg() {
for (int i = 0; i < rManager.getInstance().iceBergArray.length; i++) {
rManager.getInstance().iceBergArray[i] = new IceBergEnemy(
new Sprite(randNumber(200, 700), randNumber(0, 480),
rManager.getInstance().iceBerg_region,
engine.getVertexBufferObjectManager()) {
@Override
public boolean onAreaTouched(final TouchEvent pSceneTouchEvent, final float pTouchAreaLocalX, final float pTouchAreaLocalY) {
this.setPosition(pSceneTouchEvent.getX(), pSceneTouchEvent.getY());
if (this.getY() > rManager.getInstance().camera.getHeight() - (this.getHeight()/2) || this.getY() < 0 + (this.getHeight()/2))
{
this.setPosition(200 - (pDifficultyLevel * 20),
-100);
showScore(50, " ice berg!");
this.setVisible(false);
}
if(pSceneTouchEvent.isActionUp())
{
updateScore(50);
GameManager.getInstance().updateTotalIceBergEnemiesKilled();
}
return true;
}
});
rManager.getInstance().iceBergArray[i].getIceBergSprite()
.setPosition(
rManager.getInstance().iceBergArray[i]
.getIceBergSprite().getX(),
rManager.getInstance().iceBergArray[i]
.getIceBergSprite().getY());
rManager.getInstance().iceBergArray[i].getIceBergSprite().setScale(
0.8f);
this.registerTouchArea(rManager.getInstance().iceBergArray[i]
.getIceBergSprite());
this.setTouchAreaBindingOnActionDownEnabled(true);
attachChild(rManager.getInstance().iceBergArray[i]
.getIceBergSprite());
}
}
一些碰撞！
else if (rManager.getInstance().iceBergArray[2]
.getIceBergSprite().collidesWith(
rManager.getInstance().carArray[r]
.getCarSprite())) {
rManager.getInstance().carArray[r].setCarSpeed(0f);
}
else if (rManager.getInstance().iceBergArray[3]
.getIceBergSprite().collidesWith(
rManager.getInstance().carArray[r]
.getCarSprite())) {
rManager.getInstance().carArray[r].setCarSpeed(0f);
}
else if (rManager.getInstance().iceBergArray[4]
.getIceBergSprite().collidesWith(
rManager.getInstance().carArray[r]
.getCarSprite())) {
rManager.getInstance().carArray[r].setCarSpeed(0f);
}
else if (rManager.getInstance().iceBergArray[5]
.getIceBergSprite().collidesWith(
rManager.getInstance().carArray[r]
.getCarSprite())) {
rManager.getInstance().carArray[r].setCarSpeed(0f);
}
我发现有很多教程，但似乎没有一个参考对象的数组，而这正是我需要的。如果有人可以帮助我或提供某种快速教程，那么将不胜感激。谢谢！！
