Sonic RDX Update

lol wut?

Below is a list of all sonic/metal sonic's animations. The address the current animation is stored at likes to jump around alot so posting the address would be useless (07315264 is the current offset working for me). You can use these values plus a debugger to find the assembly code in sonic.exe to make your animation swaps permanent.

Well it has been for awhile with the latest version of the super sonic hack that replaced metal sonic instead of sonic... I'm thinking the best way to do a super sonic hack would be a routine that changes "03B18DB5" to 1 when you have +50 rings and press b while in a ball, with the latest version of the super sonic hack.

tl;dr - no, it only marginally helps the quest for a true super sonic modification.

However it does allow for virtually any animation swap. You can totally remove sonic's surfer stance, or make it the default. You can even make sonic run by gliding and all that fun junk. I personally use it for making sonic do a cool flip after a homing attack.

 

I saw a few snowboarding animations that seemed a tad out of place... perhaps they're the old ones. Got a source on the originals I can compare them to?

 

ok so I found and mostly cracked the object's collision data. The way it works is pretty simple. The collision struct is loaded before the object struct. The game then takes the coordinates and creates spheres in which collision with polygons can be calculated - if an object isn't within one of these spheres then sonic will simply fall through any polygons he clips. There are also bitflags at the end of the struct that do interesting things like make the object act like water, lava, etc.

Here's the struct, its 0x24 bytes long

Struct Collision Data 0x24
Float X position; // x-location of the collision sphere's center
Float y position; // y-location of the collision sphere's center
Float z position; // z-location of the collision sphere's center
Float Spheresize; // Not sure if this is diameter or radius
Float Unknown; // has always been 0 as far as I've seen
Float Unknown; // has always been 0 as far as I've seen
Dword Objectpointer; // points to OBJECT struct
Dword Unknown; // again, always 0
Short Col flags; // is a toggle for collision?
Short Surface Flags; // These can hurt sonic, support sonic, take traction, etc

The standard collision/surface flag combination seems to be 00 00 00 00 01 00 10 80
If you apply those flags to an object that is normally non-solid, the game will calculate collision for it.


oh and just in case you're wondering, YES this does vastly improve our ability to edit levels.

 

Sorry for the double post

yes, the island is solid.

 

Yep. It can also be used to make him not float at all, or to make him use his light dash animation for running.

Any animation can be swapped for another one.

 

No not quite a level creator, I use a hodge podge array of different programs and a knowledge of the game programming to edit the levels... I really am looking to one day to make an all-in-one level editing solution, but I have to finish cracking the game all the way open first.
