[AS3] error help again :(

[goldleader23]

I just restructured my entire game, because it wasn't working right. I cleared up about 20 compiler errors and kept playing with stuff, but now I get this. It's been bugging me all day. I'm sure I'm just overlooking something, and there still might be a lot more work to do. Also, I'm still trying to figure out the whole "Class" thing, if anything seems off.

TypeError: Error #1009: Cannot access a property or method of a null object reference.
	at vars$cinit()
	at global$init()[C:\Documents and Settings\Me\Desktop\Breakout\Flash Stuff\vars.as:11]
	at Breakout_fla::MainTimeline/frame1()[Breakout8_fla.MainTimeline::frame1:136]

A note on organization: I have code that covers the first three frames on one layer, and code that is for each of those frames individually on another layer. It looks like the error is pointing to line 136 (if I'm reading that right), but neither layer goes up that high, which led me to think it's combining the total lines of code. That also means I have no idea where to look for that part of the error.

Sorry for the long post.

Nobody, huh?

[billowillo]

just make sure that you remove everything that is trying to acess another thing properly, those errors are always the hardest to trouble shoot. try commenting out some parts of the code until it works to help pin point it.

[Woadraiders]

The error seems pretty obvious to me.

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at vars$cinit()
at global$init()[C:\Documents and Settings\Me\Desktop\Breakout\Flash Stuff\vars.as:11]
at Breakout_fla::MainTimeline/frame1()[Brea kout8_fla.MainTimeline::frame1:136]

Notice how it says "at vars$cint()

That means when the vars class is initiated. And since you don't have a constructor, and there are no instances of the var class, it must mean as soon as it's imported or maybe even when the flash is compiled, and it doesn't have to be imported at all.

So then it's not finding blueBlock._root.pacball or whatever you wrote, it's null, it hasn't been defined yet.

And I'm not sure when or where you add to blueBlock._root. All I know is it thinks that it is null, so you need to change something. I recommend having a static Init() function or just setting those two properties. You would do either of these AFTER you make sure to add blueBlock._root.pacball.

Hopefully that helps? I don't recommend setting variables with object references straight out of the class definitions ever, just do it inside of an init function so you don't have to assume.
