i am tring to debug this problem for about a week but had no luck in it.
Take a look at this image above. This is how i want the bullets to look like. shoot red lines.
Now take a look at this image above. I am tring to make my enemy boss shoot blue bullets. the blue thing you see in image is the bullet. this is the problem it is not shooting the way i want it.
i have two arraylists. 'enemyBossStore' arraylist will online hold one enemy boss. 'eBBulletStore' will hold enemy bullets.
main.java
EnemyBoss enemyBossObject;
ArrayList<EnemyBoss> enemyBossStore = new ArrayList<EnemyBoss>();
EBBullet eBBulletObject;
ArrayList<EBBullet> eBossBulletStore = new ArrayList<EBBullet>();
...
public void actionPerformed(ActionEvent e)//main game loop
{
....
levelsObject.nextLevel(enemyBossObject, enemyBossStore); //create emeny boss in this class
...
//user methods on Enemy Boss. so it can move and shoot
for(int i = 0; i < enemyBossStore.size(); i++){
enemyBossObject = (EnemyBoss)enemyBossStore.get(i);
enemyBossObject.enemyBossMove();
enemyBossObject.enemyBossShootBullet(eBBulletObject, eBossBulletStore, topMenuObject);
}
//create Enemy Boss bullets
for(int i = 0; i < eBossBulletStore.size(); i++){
eBBulletObject = (EBBullet)eBossBulletStore.get(i);
if(!eBBulletObject.getDead()){
eBBulletObject.eBBulletMove();
eBBulletObject.eBBulletWCollision();
}
else
eBossBulletStore.remove(i);
}
}
...
public void paintComponent(Graphics g)
{
...
//create Enemy Boss on level 4
if(topMenuObject.getLevel() == 4){ //test to see if its lvl 4
enemyBossObject = (EnemyBoss)enemyBossStore.get(0); //paint enemy boss
enemyBossObject.paint(g);
//paint Enemy Boss Bullet
for(int i = 0; i < eBossBulletStore.size(); i++){
eBBulletObject = (EBBullet)eBossBulletStore.get(i);
eBBulletObject.paint(g);
}
}
...
}

in level class iam creating the enmey by these two lines
EnemyBoss enemyBossObject = new EnemyBoss(600, 100);
eBossBulletStore.add(enemyBossObject);
