Flash support is completely broken now

[missingno]

I know Unity has stopped supporting Flash, but I still have a project to finish with it and I updated to NGUI 3 and now Flash is broken.

It doesn't even compile, I was able to get it to compile and run in the Editor by hacking around a few things using #if UNITY_FLASH statements, but now when trying to build I get errors about being unable to resolve T in NGUITools. Obviously T is and always has been used in NGUITools so I'm unsure as to what changed and why it suddenly doesn't work.

ArenMook or anyone else have any ideas ?

[missingno]

I've gotten some progress, I was able to solve the previous error by replacing one of the generic functions in NGUITools with multiple versions for each type that was needed.

However now I am getting the following in EventDelegate anywhere either .Target or .Method is used:

1. /Temp/StagingArea/Data/ConvertedDotNetCode/global/EventDelegate.as(81): col: 153 Error: Access of possibly undefined property Method through a reference with static type Function.

1. /Temp/StagingArea/Data/ConvertedDotNetCode/global/EventDelegate.as(81): col: 153 Error: Access of possibly undefined property Target through a reference with static type Function.

Is anyone able to help me ?

Reflection is not supported in Flash, which is why there is no reflection support defined up at the top of the file for flash platforms. Sounds like I need to do another pass with the flash platform targeted though.

[missingno]

thanks for the quick response, any idea on a time frame for that ?

I'm on a deadline and I need to have a Flash build. I've just been trying to make workarounds for flash the last couple days hoping to at least get it running and this is the last step. I tried just simply commenting out the .Target and .Method references and it then compiles, builds and runs (albeit with a few oddities, likely due to not setting some things in EventDelegate, but the point was to see if any other problems appeared).

[ArenMook]

Try this file.

[missingno]

almost, only getting the following now:

1. /EventDelegate.as(89): col: 22 Error: Call to a possibly undefined method Object_Equals_Object through a reference with static type Function.

[ArenMook]

Line 89 is a bracket for me. Which code is it referring to?

[missingno]

It's line 89 in the converted AS code, in the C# code it is line 114 (i believe).

Lines 111 - 120 in C#

1.                 if (obj is Callback)
2.                 {
3.                         Callback callback = obj as Callback;
4.                         if (callback.Equals(mCachedCallback)) return true;
5. #if REFLECTION_SUPPORT
6.                         return (mTarget == callback.Target && string.Equals(mMethodName, GetMethodName(callback)));
7. #else
8.                         return false;
9. #endif
10.                 }

converts to lines 87 - 90 in AS:

1. if ($obj is Function) {
2.         var $callback: Function = $obj as Function;
3.         return $callback.Object_Equals_Object(this.EventDelegate$mCachedCallback$);
4. }

[ArenMook]

Ah, another fail on the Flash side stemming from the shoddy code conversion. Try this function.

1.         public override bool Equals (object obj)
2.         {
3.                 if (obj == null)
4.                 {
5.                         return !isValid;
6.                 }
7.  
8.                 if (obj is Callback)
9.                 {
10.                         Callback callback = obj as Callback;
11. #if UNITY_FLASH
12.                         return (callback == mCachedCallback);
13. #elif REFLECTION_SUPPORT
14.                         if (callback.Equals(mCachedCallback)) return true;
15.                         return (mTarget == callback.Target && string.Equals(mMethodName, GetMethodName(callback)));
16. #else
17.                         return callback.Equals(mCachedCallback);
18. #endif
19.                 }
20.                
21.                 if (obj is EventDelegate)
22.                 {
23.                         EventDelegate del = obj as EventDelegate;
24.                         return (mTarget == del.mTarget && string.Equals(mMethodName, del.mMethodName));
25.                 }
26.                 return false;
27.         }

That did it Thank's for the very quick and active work on this.

Now that it's building I can get to work on finding and fixing the problems that don't seem to make any logical sense when using unity flash ...
