    Make a really efficient game tutorial (Efficient game, not necessarily efficient tutorial) please!

    I would suggest making the back of the health bar red so that losing health removes green and "adds red"

    This was a really good change, simplified things a lot. I have some animation that plays when the player runs into a ship. Before making Physics class simpler, The animation would sometimes spawn on ships that weren't hit at all. Some weird bug probably because things weren't always synchronized.

    Also, it helped me to change EntityA and EntityB to BulletEntity, ShipEntity, and they both extended Entity. And then myship was just entity.

    I've learned some much from these videos! Thanks RealTutsGML!

    @1:57 you could make it even simpler by just returning the intersect check expression…say:
    return enta.getBounds().intersects(entb.getBounds());

    and it actually doesn't matter if you do enta against entb or entb against enta, since its an intersection check, if a intersects b, b intersects a, as far as i've noticed

    Thanks. I'm expanding the game to be more. I'm adding bosses power ups, menus, and all kind of stuff. This was a great tutorial to start with and I've learned so much and I've gotten so much better at Java!

    How do you clear the enemies in the game after HEALTH = 0?

    I added that if health = 0 then state = menu, but then when I click play again the game is not cleared…the enemies are still in the game…. how to fix that?

    This is how mine turned out: http://imgur.com/SuqpPzT

    I used the classic 3 hearts instead of a healthbar, I've drawn and animated the sprites myself and when you die a message dialog pops up (also changed some fonts). I think it looks pretty damn good for a very simple game 😀 Though now I'll follow some tuts of someone else, since I think your code isn't very efficient, well written or well organized. You also didn't always explain what was going on (I think that's because you didn't really understand it yourself but just knew how to do it). No offence of course, I really enjoyed your series and I think it was the best one out there to start java game development.

    So here's a very big thank you +RealTutsGML !

    With very small modifications to the code in this tutorial I made this:

    It really is surprising how much a little effort in the appearance of the game makes it look so much better.

    I would like to see a small tutorial to make it more efficient w/o needing to import all that stuff all the time as you mentioned. If you already did a tutorial like that please point me to which video it is. Thanks, John

    Not sure if you still answer on this thread but if you do could you just tell me how to reset the game after you die ( go back to menu screen and how to reset the enemy count and kills). Great videos, Thanks.

    For your next tutorial, you should show how to do that cool little image faded trail like the one in your most recent video about ludem dare, the little box game thingy. (The effect that the player has coming from it when it moves). 😉

    You could make a simple help screen by using drawString(); on a new enum, like the menu without boxes, and if you needed pictures create a "Pic" class, or something, that draws from textures/animation. Or, if you needed multiple classes, you could put enums within enums. By then it would be more efficient to create an "Enum" class.

    Can you do a serious in java on a simple RPG style game like with boxes and just something very simple as that? I think it could be easily explained and also people can learn a ton from that, just an idea for your next serious maybe?

    Can you do one on delta time? So that everything that moves on the screen moves at the same speed on every computer (No matter the specs) 🙂

    I was wondering if you could do these few things before you end the series.
    1.Make the Help button work
    2.Make it that when your health runs out a losing screen with a retry button comes up
    3.this isn't that important but fix the framrate drop issue
    thanks

    could find what bullet that killed the enemy by this
    control.addremove(main.ea.get(Physics.getWhat_do_blow_up()));
    What_do_blow_up was equal to i in the collision event
