SA2 Event Viewer and splitEvent not working for certain events

[tbentham]

Hi,

Most SA2 events aren't working for me in both SA2 Event Viewer and splitEvent. Here's the error for splitEvent:

Unhandled Exception: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
   at System.ThrowHelper.ThrowArgumentOutOfRangeException(ExceptionArgument argument, ExceptionResource resource)
   at SonicRetro.SAModel.NJS_MOTION..ctor(Byte[] file, Int32 address, UInt32 imageBase, Int32 nummodels, Dictionary`2 labels, Boolean shortrot) in E:\Programs\sa_tools\SAModel\Animation.cs:line 287
   at splitEvent.Program.ReadMotionFile(String filename) in E:\Programs\sa_tools\splitEvent\Program.cs:line 239
   at splitEvent.Program.Main(String[] args) in E:\Programs\sa_tools\splitEvent\Program.cs:line 46

And the error for SA2 Event Viewer:

The following events do work in both, but they're literally the only ones:

e0000, e0100, e0105, e0109, e0118, e0124, e0131, e0200, e0206, e0211

Some patterns I noticed that may or may not be significant:

• All three story intros work.
• None of the Hero story events work except the intro.
• Tails is the only main character who does not feature in any working event.

Hope that's enough to go on.

I know exactly why this is happening, but I don't know how to fix it. These events contain shape motions with only one unique vertex array, but the parser needs at least two in order to determine the length of the vertex array. I checked how the game handles this when loading events, and it doesn't; it waits until the motion is called upon and uses the data from the model to determine the length of the array, which is not something we can do.

I did a thing so all the events should work now, tested e0002 and it works fine.

Nice! It all seems to work now.
