}
}
}
}
I need to finish this program soon so help is greatly appreciated. PS code is long as I have no idea where the error is since flash doesn't want to give me the line.
The error is in this line: function Mainp() The problem is that it is located on the timeline, you cannot place constructors on the timeline. You should find the main *.as file and place that Mainp() in there, inside the class Mainp definition.

It's hard to understand what specific logic you want to implement, but it looks like you need to create an enemy only once. And it looks like the problem is: you call the Timerfood method in the onEnterFrame listeners, which itself is called many times per second according to the framerate of your app (e.g. 30 times per second).
I would suggest you to remove the call of Timerfood from the onEnterFrame method, and put it in the end of the init method.
Well, my English is not very good, but I try tell the possible reason,
the method Timerfood() is called on method onEnterFrame(), that initialize myTimer for each frame, so may be the solution is, remove this line into TimerFood() method:
var myTimer:Timer = new Timer(10000,1);
and call TimerFood() only in startgame() method.
I hope you can understand me.
I'm quite new with actionscript, and have been scrapping together a little test game to sort of get used to the language, get my feet wet. The premise behind the game is pretty average, I have a character that can move in 8 directions, can pick up several keys that are randomly placed, and open a door when he possesses a key.
The problem comes in to play with the bullet shooting. I don't know much about trigonometry, so when a key is pressed, i just use the .rotate property to turn the player. I pass the .rotate integer into my bullet class and use that to tell which direction the bullet should travel. It works perfectly for the up, down, and right movements, but when the character is facing left the bullet is created but has no velocity whatsoever, and for the life of me I cannot figure out where the error in the code is.
If someone could look over my code and help me out, I would be much appreciated. I'm sure it's something simple that I'm just missing. I know it's a bit sloppy, so if there's any other tips you want to pass on to a novice please feel free!!
Thank you so much guys.

It looks as though you're only checking for collisions when the shoot button is pressed, which would explain why it's not happening quickly. I suspect you want to run testCollisions every frame instead:
stage.addEventListener(Event.ENTER_FRAME, testCollisions);
I am creating a platformer game. However, I have encountered an error after creating a collision boundary on platform to make the player jump on the platform without dropping.
I have create a rectangle box and I export it as platForm
Here's the output of the error:
The error keep repeating itself over and over again....
TypeError: Error #1009: Cannot access a property or method of a null object reference.

It's a little difficult to see exactly what is happening without being able to run your code, but the error is saying that something within your BoyMove() method is trying to reference a property (or method) of something that is null. Having looked at the BoyMove() method, I can see that there isn't a lot there that could cause this problem. The other two candidates would be
MovieClip(parent)
or
MovieClip(this)
You are attempting to access properties of both of those MovieClips. One of them must not be initialized as you expect. I suggest you do some basic debugging on that method by commenting out the lines with MovieClip(parent) and see if you still get the error. Then try the same with the line with MovieClip(this). That should be able enough to isolate the issue.
I have object char in my stage and i controlled it with main.as but when i decided to make it char.as and to add it in main.as become the error..
