So my game in Java has collision detection done. Now the problem is calculating the damage the ship takes. Calculating it during the collision detection process seems to be a bad idea seeing as the ship initial lives of 3 decreases to 0 pretty quickly. This is because my collision detection is done using a for each loop.
It would seem the culprit would be the bounding box collision detection in the gameloop.
Each attack from the monsters is only suppose to take out one life from the ship.
The thing is I can only calculate the ship damage if a collision detection happens and the for each loop is the culprit that makes damage calculation goes too quick.
public class Ship extends Sprite implements KeyListener{
private int life;
public Ship(double x, double y) {
// ship life
life = 3;
}
public void setLife(int life)
{
this.life = life;
}
public int getLife()
{
return life;
}
}
public class Game extends Canvas implements KeyListener{
public void run(){
// basic game loop
// do not break out of the game loop when I change the state of the isRunning
while(!isLooping)
{
// laser check for every OneEye monsters in the ArrayList
for(GameComponent component: gameObjects){
if(component instanceof Laser)
{
((Laser) component).checkMonsterCollision(gameObjects);
}
if(component instanceof OneEyeSlashSkill)
{
((OneEyeSlashSkill) component).checkShipCollision(gameObjects);
}
}
}
}
public class OneEyeSlashSkill extends Sprite {
public void checkShipCollision(ArrayList<GameComponent> gameObjects )
{
for(GameComponent component: gameObjects)
{
if(component instanceof Ship)
{
// if collision happens
if((rectangle.intersects(((Ship) component).getRectangle())))
{
((Ship) component).setLife(((Ship) component).getLife() - 1);
// remove ship object
if(((Ship) component).getLife() == 0)
{
Game.getInstance().remove((Ship)component);
// remove the key listener associated with the ship object
Game.getInstance().removeKeyListener((KeyListener) component);
}
}
}
}
}
}
