Precompiled Bytecode format

15 February 2013 - 12:31 AM

I need to execute Angelscript bytecode in my own Virtual Machine as I need to perform tasks as part of the execution that the AngelScript VM is incapable of. Currently, I am using SaveByteCode on the module, and then trying to parse the resultant bytecode. The problem so far is that I am unsure what the format of this bytecode is... it's not straight bytecodes going straight in.

I wrote a very simple AS script:

 

void run ()
{
	print("RUN CALLED");
}

 

 

Which results in the following output:

 

01 00 00 00 00 00 01 66 6E 03 		? ? ? ? ? ? ? f n ? 
72 75 6E 40 4E 00 00 00 00 01 		r u n @ N ? ? ? ? ? 
00 00 00 0C 3F 3C 00 3D 00 3B 		? ? ? ? ? < ? = ? ; 
04 01 3D 01 04 01 3D 02 04 01 		? ? = ? ? ? = ? ? ? 
3D 03 3F 0A 00 01 01 6F 6E 06 		= ? ? ? ? ? ? o n ? 
73 74 72 69 6E 67 00 04 01 00 		s t r i n g ? ? ? ? 
02 06 01 01 0A 01 00 00 00 01 		? ? ? ? ? ? ? ? ? ? 
72 00 00 00 00 05 61 6E 10 5F 		r ? ? ? ? ? a n ? _ 
73 74 72 69 6E 67 5F 66 61 63 		s t r i n g _ f a c

01 00 01 01 01 00 00 6F 72 01 		? ? ? ? ? ? ? o r ? 
00 00 61 6E 05 70 72 69 6E 74 		? ? a n ? p r i n t 
00 00 01 00 01 01 01 00 00 00 		? ? ? ? ? ? ? ? ? ? 
00 61 6E 07 5F 62 65 68 5F 31 		? a n ? _ b e h _ 1 
5F 00 00 00 00 00 00 6F 72 01 		_ ? ? ? ? ? ? o r ? 
00 00 6E 00 01 6E 0A 52 55 4E 		? ? n ? ? n ? R U N 
20 43 41 4C 4C 45 44 00 00 00 		  C A L L E D ? ? ? 

 

 


How would I go about loading this and other scripts? The AngelScript documentation doesn't go into detail about the specifics of precompiled bytecode, only the API side of things.
