useflashpunk / FlashPunk

A free ActionScript 3 library designed for developing 2D Flash games. It provides you with a fast, clean framework to prototype and develop your games in. This means that most of the dirty work (timestep, animation, input, and collision to name a few) is already coded for you and ready to go, giving you more time and energy to concentrate on the design and testing of your game.

Code errors report #59

While I was using flash punk in FDT5, it generated an error report which cause I can build the project. Here is the error report.

So I took a look at these. The first two are objections to calling "return updateBuffer()" from in a function with return type void. However, since the updateBuffer() method also has return type void, I think it's legal, if perhaps inelegant. It would be easy enough to separate out the function call and the return statement, if we wanted to.

I don't understand the Hitbox issues. All the calls are to list.update(), where list is a MaskList object (inherited from Mask). The MaskList class has an update method (overriding the empty version in Mask), so it seems like it should be fine. The only thing I can think of is the fact that update() has the protected access type, but since both Hitbox and MaskList are subtypes of Mask (where the update method is declared) it seems like either one should be able to call it on the other.

All the rest are complaining about types. The two in Input are semi-legit. They're about the implicit conversion of integers to Booleans (where anything non-zero is treated as true). That could be tightened up with a cast or a the addition of "!= 0". The rest are bogus. Class objects are pretty weird, and the program doesn't seem to understand that given some variable X holding a class, "new X" will have a different type than X did.

I'm running into this as well using the latest FDT5. I've submitted pull requests for the Input.as and Mask inheritence issues and will see if I can help with any workarounds on the others. I'll see if I can pull down a Flash Builder trial to see if the same errors come up. (eg. is this a Mac only issue, an FDT5 only issue or even an issue with the latest Flex SDK)

I don't have any of the mentioned issues, I use latest Flex SDK 4.6, under Win 7 on FlashDevelop. This seems to be something relating to, as erikyuzwa said, either FDT or MacOSX.
