****PROBLEM SOLVED****
If your missile is killing enemies without hitting it as soon as it gets fired, check in the "Missile.as" file, find the "onEnterFrame()" function, and take a look at the "if" condition inside the "for...in" loop; at the end of the condition declaration there shouldn't be any ";".
Example: THIS IS WRONG
if (this.hitTest( _root.hero.enemies[i] )) // NO ";" IN THE END
{
//SOME CODE
}

sorry guys, i have a problem with the " hitTest() " function. I checked the cod a billion time, but everytime my hero ship fires a missile, the bullet appears for a millisec and vanishes, and ANY enemy is destroyed (despite of its "_x" and "_y"). Basically, the missiles are fired and make the enemy explode as soon as they're fired, without phisically hitting it.

If you loaded the downloadable source and your missiles won't hit anything, go to Control > Clear Publish Cache and Test Movie.

for some reason the this.hitTest(_root.ship) if statement won't return true... it is in the onEnterFrame function... anyone have any idea what is going wrong?

Vind777 made a very useful comment, i tried ages to figure out, that it is only working with a different instant name.

If your explosion animation is looping, and you can't figure out what's wrong, make sure your Explosion.as file is saved in the same folder as your main flash file.

Same with Markonan here, the array puts me in error. And I don't think the instance name '_root.ship' is the problem. Actually, I found an error window right beside the timeline window, "There is no property with the name 'enemy'" it says. I have little idea what it means, can somebody help?

i have this problem.. after i have added the collision between missile and enemy ship th rate of fire of hero ship change.. when the test begin it's only one missile but some enemy after it's 2 3 4.. any solution?

I get an error when I put the array into my code. When "enemies = [];" is put into my code the enemies stop spawning, bullets won't fire, and the background doesn't move like it's supposed to. I altered the gameplay slightly (ships coming from random locations, top to bottom, left to right, etc., bullets shooting all directions, and background moving with the ship instead of only horizontally) but no changes that I can think of that would alter it enough to do this. I tried it without the "enemies = [];" (and the "var enemies;" still created) and I don't have any problems whatsoever. I also tried it by doing "enemies = new Array();" but got the same issue. Any ideas?

Neither Firefox nor Internet Explorer is allowing me to download the source files. Could somebody PM me a direct link?

This tutorial is lacking in its explanation of a for... in loop. How exactly does it work? I see it's in the onEnterFrame method so for each frame does it check the entire array?

.....don't know if this is a re post or if my internet is acting up.....
short version
i need help getting the full source code, or the whole original game file: which ever it was i had before my computer bsod-ed on me. i have all i need but no file to copy the explosion from to paste into my own.
all help is great thanks
-i did right click and download the source code from multiple pages but none have the file i need

@SlayerOfPersians I almost had that problem... I accidentally put it in in a way that my second ship launching code was completely separate from the first, and was launching one each frame... I caught on when I was getting 61 enemies every two seconds instead of 1.

I don't know if anyone can help me out but, I'm getting this in my output
"256 levels of recursion were exceeded in one action list.
This is probably an infinite loop.
Further execution of actions has been disabled in this movie."
I assume it's coming from the missile because it pops that up as soon as the missile hits an enemy ship.

If i am reading the first page correctly....... this should be the apex of the Tutorial process, i'm very happy to have made it this far, just 5 hours ago i would have looked at these codes and went "WTF!?!?!", thank you Kongregate for your easy tutorials and helping out us new people who want to take a hand at game developing.

step 9 causes a memory leak. each time we make the enemy array larger, the for loop that checks if your shots hit anything takes a little but larger. if you decided to expand the game with that code, you'll start to get massive slowdown as the array reaches the ten thousands or so. any chance someone reading this can help me write a splice function to keep the array size reasonable?

Hi guys. When I try to use ._currentFrame and ._totalFrames there is an error that reads: "there is no property with this name". Help plz

can someone tell me how to insert the explosion in cs5.5? cause when i try to open the Fla file it says "Unexpected file format"

I have searched through my code a million times, and cant find any reason why my explosion animation loops constantly when I destroy an enemy. I even tried importing the kongregate explosion file + code, to no effect, so the problem obviously doesnt lie with explosion.as file. PLEASE help, its the only major problem Ive encountered so far and am unable to figure this one out on my own, ive been stuck on it for two days!

Everyone who can only shoot half their enemy ships, listen up: You're not putting all the enemy ships in the enemy array. Many of us weren't careful when we copied and pasted the Shootorial code into the onEnter function, so now we have two independent ship launching codes. Basically, if you forget to delete a certain bit of code, half of the new enemy ships are not pushed into the array and so aren't affected by missiles. To correct this, look at the source ship.as and compare it to your code under the onEnter function, specifically the part that reads "if (enemyTimer..."
I deleted a line from my ship.as to match the source, and it works without a hitch now!

Got another question, im not using the downloads with this, im making all that myself so i can learn it too, does anyone know a good animation tutorial, i looked on the web but cant find anything that seems to help/work

well i tried this and i got to the point with the explosion and now my game just flashes every few seconds, its just white and then for like 1 frame the game shows, and then goes white again, i deleted everything i had added before this and it still does it, someone PLEASE help me, ive been working for the whole day on this and i really dont want to have to start over only to make another damn mistake

For all people who have problems with missiles that don't make enemie explode: after a week I finally solved it! You have to make sure that the name of your 'ship' is exactely filled in the codes, and it must be different from the class name. So I called it 'ShipInstance' and it only worked after I filled in this:
for(var i in _root.ShipInstance.enemies)
{
if(this.hitTest( _root.ShipInstance.enemies[i] ) )
{
this.removeMovieClip();
_root.ShipInstance.enemies[i].explode();
}

@jumpking55, that's because we are trying to access to a variable array which if you remember we have it defined in the ship. it's very wise to store it there because always will be the ship instance before any missile or enemy, so we can assure that the array enemies exists. Notice that is like a path, you can say: "from the root timeline (the main one), look for the ship, then inside it, give me the array enemies". I hope this helped. :P
