Arraylist hatasi icin yardim.

Merhaba arkadaslar ben basit bir uzay oyunu yapiyorum fakat bu hatanin icinden bir türlü cikamadim.

Atış hedeh ile ile karsilasinxa hata veriyor.

Carpisma sinifimda yazdığım kodda mi sikinti var.

public static boolean carpisma(Player pl,UzayGemileri ug,ArrayList<UzayGemileri> ugEkle,ArrayList<Fire> fire)
{
for(int i=0;i<ugEkle.size();i++)
{for(int j=0;j<fire.size();j++)
{
if(ugEkle.get(i).getRct().overlaps(fire.get(j).getRct()))
{
ugEkle.remove(i);// duaman gemisi siliniyor.
fire.remove(j);// mermi siliniyor.
pl.SkorSayisi(); // player puan aliyor.
}
}
}

Oyunun calistigi döngü burda.
private ArrayList<UzayGemileri> ugEkle;
private Fire f;
private ArrayList<Fire> fires;

Public SpaceWorld ()
{
f = new Fire(pl.getPlRct().x,pl.getPlRct().y-pl.getPlRct().width/2-10);
ug = new UzayGemileri(/*Gdx.graphics.getWidth()/2,Gdx.graphics.getHeight()*/);
ugEkle = new ArrayList<UzayGemileri>();
fires = new ArrayList<Fire>();
GemiEkle ();
}

public void GemiEkle()
{
gemiSayi=1;
for(int i =0;i<gemiSayi;i++)
{
ugEkle.add(new UzayGemileri());/*ug.getRct().x,ug.getRct().y+300)*/
}
}
