Ready Sonic help?

Hi there, I was experimenting with Ready Sonic dissasembely earlier only to be stumped when trying to add new objects... the reason being I have never seen an object index like this. I can only assume it is based on those new fangled dissasembelys that i absolutely hate as they seem to overcomplicate everything!!! Can anybody explain to me how it works and how I would go about adding new objects to the object index?


just incase you dont know what I am on about here is the offending file....

I don't like them much either, but they aren't that complicated.


When you see:





ptr_SonicPlayer: dc.l SonicPlayer ; $01


ptr_Obj02: dc.l ObjectFall


ptr_Obj03: dc.l ObjectFall


ptr_Obj04: dc.l ObjectFall



the equivalent in the 2005 disassembly is




dc.l Obj01, ObjectFall, ObjectFall, ObjectFall



Each pointer (those ptr things) is an address of the rom, and each id is equivalent to the number of the object, so when you read:



id_Obj06: equ ((ptr_SonicPlayer-Obj_Index)/4)+1



it's really an equation: the ID of the object can now be called "id_Obj06", and its value equals the address of the pointer minus the address of the beginning of the object pointer list, divided by 4 (because it's a long), plus 1 because there's no object 0 (when the engine finds a 0 at the object's address, it skips it).


With that method, rather than using the "number" of the object, you can use its id, which is supposedly easier to remember, or at least easier to find in the list. It also makes it easier to reorganize the list if necessary, although for this to work properly you'd need to use those IDs everywhere in the disassembly and in the object layout files.


So to add more objects, add more entries to those lists using the same format.

 

Thank you, that worked a treat - my next problem apearas that even though i have a firesheild it dosnt display. More research required me thinks !!!

 

ReadySonic is based on the Sonic 1 SVN disassembly. Sorry to disappoint anyone.

 

Does anybody know if the guy that made this would be willing to do a version based on the 2005 dissasembely? I think it would be most usefull.

 

I think you should just get used to using the newer SVN dissasembely, rather than ask someone else to do a lot of work on something outdated.


OR just use the old dissasembely that you're used too. The bugs fixed in Ready Sonic aren't too noticeable anyway.

 

I know, I am just being lazy !!! I should really - maybe its time to get cracking on my sonic 2 hack instead.
