would it be possible to show a version of this tutorial with you being able to die? maybe even give us hit points or lives.

TypeError: Error #2007: Parameter hitTestObject must be non-null.
at flash.display::DisplayObject/_hitTest()
at flash.display::DisplayObject/hitTestObject()
at bullet/loop()

If you get this error it means you just forgot to extend the hitArea layer to frame 15

Mine is working, but with two issues:

1. The stinger from the 2nd frame is displayed, whereas I expected the STOP command to cause the stinger from the 1st frame to appear. The stinger from the 2nd frame has started disintegrating, so it doesn’t look intact.

2. When a Stinger enters the stage, everything goes jumpy, in slow motion. As soon as all stinger’s are gone, it speeds up again. Wah!

Any suggestions?

For those getting error 2007, even mike answered that in a post, the author of the tutorial says in Step 1: “Now goto your hitBox layer and right click on frame 15 and select “Insert Frame”.” You probably forgot to add it.

The best beginner’s AS3 game tutorial ever.

I like it, at this point in the tut the game is starting to take some serious shape.

I’m having one problem, and I’m still researching to see how to fix it. My “stingers” are animated with a rocket thrust on the back. But when I put the stop(); line in it stops this animation. So I’m currently trying to figure out how to make this animation play until the ship takes a hit. As soon as I figure out how to solve this I’ll come back and post something.

it seems whenever i add the gotoAndPlay(”destroyed”); code i get the error TypeError: Error #2007: Parameter hitTestObject must be non-null.
at flash.display::DisplayObject/_hitTest()
at flash.display::DisplayObject/hitTestObject()
at bullet/loop()

but if i remove the gotoandplay the error doesn’t please help me regarding this situation

I’m getting the same error

TypeError: Error #2007: Parameter hitTestObject must be non-null.
at flash.display::DisplayObject/flash.display:DisplayObject::_hitTest()
at flash.display::DisplayObject/hitTestObject()
at com.asgamer.basics1::LaserBlue/::loop()

I noticed this happens either when I shoot multiply enemies, or if I get hit and end up blowing up an enemy at the same time. In addition is slows down the animation.

Meet and Sepiantum : I had the same error, then realized it must be saying Null because the hitbox goes away. I figured this out because I noticed that the error only happens after you shoot the ship as it’s being destroyed. To get rid of the error, you have to make sure teh hitbox keyframes extend to the end of the animation. However, this introduces the bug as said above where you can keep destroying the same ship over and over - it replays the destroyed animation. I haven’t read the last tutorial yet so I dunno how to fix it but I’m off to read it now!

Thanks for the tuts!

Hey,
Thanks for the awesome tutorial!!!
For some reason, my version of this game is running very slowly,
especially when the number of stars is above 20.
The version on this page runs much faster on the same machine.
Any ideas why?

Thanks!
