Question about adding bullets to arraylists

Miles Rezak · 2016-04-22T14:28:28

So the last few days I've just been kind of polishing my game - the reason I haven't really focused on mechanics and stuff is because I couldn't get past a certain problem. A few days ago, I asked a question about rendering multiple bullets to the screen and a lot of you suggested I use ArrayLists. I tried a bunch of stuff, but that didn't exactly work (Note: I DO have prior knowledge of arraylists, so I'm not completely clueless XD). What exactly is the FORMATTING for making it work? I know there isn't a single method of doing it, but I would like some kind of sample which demonstrates an efficient technique for adding the bullet object to the arraylist, creating a rectangle at the player's coords, etc. I promise I'm not being lazy and asking for people to do it for me XD I tried all that I could but I ended up with the bullet restarting its position at the player's position whenever I press the trigger button, rather than a NEW bullet being created. I do know for a fact that my arraylist IS being updated, because I print out the size of it whenever I press the trigger button, and it updates. I know this is vague, but a vague answer is kind of what I need. I just need the concept, or the formatting for how I would go about doing it. Tl;dr : ArrayList being updated, but same bullet being reused. Thanks to whomever replies! Means a lot :D

Also, it's not really good forum etiquette to remove your questions and replace them with "[solved]". That way no-one else can benefit from the question and answer later on. When your issue is solved, reply to the thread letting other people know what the problem was. Then try to learn from the experience.

Apparently I shouldn't have even had that problem in the first place according to a few (not in a mean way at all, but it would make sense). With that rationale, why would people benefit off of a problem regarded as being 'dumb'? (My words, not anyone else's).

If my post is being down voted to oblivion because of that, here's my fix:

I screwed up my draw method. It was being called in a weird way.

Also, I've made pong. I'm confident in my abilities and look at documentation. It was a simple mistake.

Because, regardless of whether if your problem was dumb or not, other people also make mistakes.

I still makes stupid mistakes all the time, as do all other people, I would guess. There's nothing special about making stupid mistakes.

Mainly, the thing that improves with experience is your ability to troubleshoot and find the error on your own (and the ability to create some really outstanding mistakes inconceivable by most beginners).
