All you need is a class for enemy (which could extend from the same baseclass as player). With a little bit of OOP practice your loop will only have to run about 1 line of code, namely the update function of your enemies/player.
Yeah, I started looking at OOP a while after posting this, and I probably will change it soon, once I fully understand it. It would still be helpful to know what's causing this, though.

328.95 was their starting position, and then it suddenly jumps to . . . negative one million . . .
It doesn't change after that, at all.
Yep, just tried it in, good idea, no cigar though.
Damn, lol.
Probably fixed a bunch of other stuff in it, but the main problem is still there.
OH.
*slaps self*
Thanks dude, I did not think of that at all.
Bump for slow forum day?

What do you mean? I've actually drawn the enemies, and e1-e4 are their instance names.
And to stop you saying something along the lines of "You need to draw/declare them within the code", I have a slightly older version of this, with a simplified loop/array thing, and only one enemy in the
array, and it works perfectly. It's something about having the two other arrays or something else that's
messing it up.

Lots more, use google, there's also books.
Changed the fps again to try and see what's going on. In stead of what i said before, anything in hitArray does not appear at all when I run the code.
I seriously have no idea what's going on here.
Try putting all your code into something like this:
if(currentFrame == "Level 1 or w/e"){
//All your code
}That way, your code will only run for that frame.

4) It will continue to add that number. You'll want a cap for it somewhere or the number will get obscene. if(finalMovementAmount > 10){finalMovementAmount = 10;}
Yeah this is what my problem is, but it is being added somewhere. The multiplying is for deceleration when the player isn't throwing them around.
When I commented various parts out, I saw that even when I didn't have anything adding any value to moveArray, they still moved. Fast.
The same for gravity, except that's meant to happen. The trouble is, they don't stop at the ground.
I've also tried capping off both at 10, doesn't have any effect at all.
Won't really need too, since those will just be variables now, instead of elements in an array.
Eh, I didn't explain part of that well enough. There does need to be arrays since the way the rest of my code works, each enemy needs its own gravity variable, otherwise I would've made it just one.
3) If you put it at 1fps and it kind of works... why not keep it at your original fps and make the variable lower? Instead of gravity = 10, make it gravity = 2, or gravity = .1;
Also, it didn't work at 1fps, but It let me see what was going on, as at 30 it happened nearly instantly.
Since I'm not sure that you understand what's going on in my end:
Frame 1: Everything is floating in the air, where I left it on the stage.
Frame 2: Player starts to drift down normally. One enemy (e2) has completely vanished.
Frame 3: Only the player remains on screen.

Are you trying to make it so when "player" hits a cookie, the counter goes up? If that's the case, instead of
_root.cookieCounter.gotoAndPlay(2)just make a variable called cookiecount, make a dynamic textbox and give it cookiecount as a var, then put
cookiecount++;instead of the code above.
Since no one is posting, il give you the full code which when I run it, shit hits the fan.

stage.addEventListener(Event.ENTER_FRAME, stuff);There about 6 MC's there, player, e1, e2, e3, e4, and ground.
If you want anyone to apply for this, you gotta show work for what YOU can do.
I have 3 arrays, one with my Enemy MC's (e1, e2, e3, e4), one with a Gravity variable for each enemy, and one more with a movement variable for each of my enemies.
var hitArray:Array = new Array();
var moveArray:Array = new Array("0","0","0","0");
var gravArray:Array = new Array("10","10","10","10");
var i:Number;
hitArray.push(e1);
hitArray.push(e2);
hitArray.push(e3);
hitArray.push(e4);I also have a for loop, which is supposed to cycle through each enemy, and check various things.
for (i = 0; i < hitArray.length; i++) {
hitArray[i].y += gravArray[i];
hitArray[i].x += moveArray[i];
moveArray[i] *= eDecay;
if (hitArray[i].y >= ground.y) {
hitArray[i].y = ground.y;
}
if (Math.abs(player.x - hitArray[i].x) <= pRange && Math.abs(player.y - hitArray[i].y) <= pRange && hitArray[i].x >= player.x && rightAtk == true && leftAtk == false) {
moveArray[i] += atkPower * multi;
}
if (Math.abs(player.x - hitArray[i].x) <= pRange && Math.abs(player.y - hitArray[i].y) <= pRange && hitArray[i].x <= player.x && rightAtk == false && leftAtk == true) {
moveArray[i] -= atkPower * multi;
}
}The first three lines in the loop are just adding the gravity and movement values to the MC's x and y, and also decreasing the movement value. Then theres the ground code, very simple, then the attacking codes, to see if the attack button is pressed while the enemy is in range...blah blah blah.
What happens when I run this (I have other code there as well, such as for the player and keyboard inputs, but only the loop is causing trouble), All the enemies in the array vanish really quickly. After turning the FPS down to 1, I saw they're just moving off the screen really fast. I've also done some testing, and found that the problem only happens when these two lines are run:
hitArray[i].y += gravArray[i];
hitArray[i].x += moveArray[i];So yeah. Honestly, I've never really used arrays and for loops together before, so I have no fuckin idea whats going wrong.
PS: If anyone can tell me how to make it so that every time I add an enemy to hitArray, it adds one more value for it in both moveArray and gravArray? That way I can have as many things on there at once as I like, and it does it automatically. Thanks in advance.
Oh wow, hadn't checked this.
Thanks for all the responses, il start on this right now. ^^

1) What is a 'document class'. Is it special? Can't I just make any given class and call it from the timeline?
2) When do you extend MovieClip and when do you extend Sprite?
3) What's up with the import statements (import flash.events.*, etc.)?
4) Should big games have lots and lots of classes or should I try and put more code on the timeline?
I've been using Google but I'm still shaky on these details, so if you can help, I'd really appreciate it.
This is helpful
The first two I can't give a good explanation, but the last two I can.
Those import statements usually aren't necessary, but sometimes are, and are essential if you create your own class. They tell flash to import various bits of code to make it work.
Big games should probably be split up, to keep it more organised, but it is possible to do it in one place, but this isn't recommended.
Maybe.
I haven't used for loops and arrays much, how would you do that? I know you gotta make an array with all the instance names and whatnot in it, then make a for loop (for(i=0;i<total # of things;i++){//stuff}), but I don't know how to cycle through each instance name separately.
Eh, that's the way I already knew, lemme explain what I wanted.
Say there 5 boxes hovering in the air, and the ground is below them. I'd like some code to check weather ANY of them are below
if(anything.y >= ground.y)then it starts checking their instance names
if(name == obj1){then it takes appropriate action.
I know other ways of doing this, like that you posted, but They require you to put in each one individually or something, but with this you could simplify it into one code.
But now that I think about it, I'm not sure weather it would be any faster or not.
Sorry, didn't have enough space in the title to make it clearer to what I'm asking.
AS3 by the way
Quick question, is there a way to check if anything is below a certain point? Instead of if's checking for each thing individually, is there something to check if anything at all is below a certain point?
Niether of them right, of course.
We can't tell you who that is. Lurk 4chan for about 5 minutes to find out.
Especially if you're going to shoot them at some point.
