Just got home a bit ago, got a chance to try to fix some opcodes. Looks like they messed with the x,y,z coordinates again. Hopefully it's not as bad as last time. Will try to post the opcodes I found in a while.
Just got home a bit ago, got a chance to try to fix some opcodes. Looks like they messed with the x,y,z coordinates again. Hopefully it's not as bad as last time. Will try to post the opcodes I found in a while.
first time i've played with seq in years, got it mostly working:
opcode id="5772" name="OP_PlayerProfile"
opcode id="60a8" name="OP_ZoneEntry"
opcode id="18cd" name="OP_NewZone"
opcode id="4788" name="OP_NpcMoveUpdate"
opcode id="2c22" name="OP_Death"
opcode id="4234" name="OP_DeleteSpawn"
opcode id="781f" name="OP_RemoveSpawn"
undo these previous changes to spawnshell.cpp and spawn.cpp:
- int16_t y = pupdate->y >> 3;
+ int16_t y = (pupdate->y + pupdate->y) >> 3;
- setPos(s->x >> 3, s->y >> 3, s->z >> 3);
+ setPos(s->x >> 3, (s->y + s->y) >> 3, s->z >> 3);
x/y/z are correct, not sure about the rest:
signed deltaZ:13; // change in z
unsigned heading:12; // heading
signed padding0020:7;
signed deltaHeading:10;// change in heading
signed x:19; // x coord
signed padding0004:3;
signed animation:10; // animation
signed deltaX:13; // change in x
signed padding0008:9;
signed deltaY:13; // change in y
signed y:19; // y coord
signed padding0001:10;
signed z:19; // z coord
signed padding0016:3;
Thanks!
I've applied the changes but I don't know if I've applied them correctly. Are you saying to change the x/y/z coordinates in every location that they show up in everquest.h? I've changed them all I think and things are mostly working. The two most obvious things I see now are that I don't see my own character and the heading, and NPCs (mobs, pets, mercs) move ok but PCs don't seem to. Is that what you expect or have I applied something incorrectly?
Again, much appreciation. I'm ok with the opcodes but those other changes really get me. Why do they change them so much from patch to patch? Isn't that a reflection of how they are passing/storing the information between the server and the client?
Any changes in the way the client decodes information have to be changed in ShowEQ too. In the previous patch, it was adding the 'y' coordinate to itself at the start of the function where it unpacks physics data -- for some reason they reverted that and only they (Sony) can say for sure why.Originally Posted by rogues
Heh, thought so. I think they're doing it to screw with us...
OP_GroundSpawn is now 56b2
Yup, I ran out of time to work on it so posted what I had.
I'm thinking just to screw with us, I can't think of any practical purpose for randomly reordering those things.Again, much appreciation.

Ok, I have other PCs moving now but they aren't in the right location. I must have messed up one of the changes above regarding player x/y/z.
I reverted the playerselfpos structure back to what it was pre-code and with the opcode changes I've made the player shows up on the map but not in the right spot. The structure appears to have changed for players but maybe not in the same way it did for npcs?
Oh, the other big spawn change I found is 0be5 for OP_ClientUpdate
No matter what I do, I get what looks like Missile Command on crack. What structs need to be changed in everquest.h? Do I change the pos structs in spawnshell.cpp?
Thanks!!

Yeah, the player pos struct is different and uses floats instead of unsigned
opcode id="142c" name="OP_MobUpdate"
opcode id="607d" name="OP_ClickObject"
got deltaX/deltaY in the right places now so movement vector lines are correct.
do heading/deltaHeading/deltaZ/animation do anything useful for seq?
signed deltaZ:13; // change in z
unsigned heading:12; // heading
signed padding0020:7;
signed deltaHeading:10;// change in heading
signed x:19; // x coord
signed padding0004:3;
signed padding0008:12;
signed deltaY:13; // change in y
signed padding0001:7;
signed deltaX:13; // change in x
signed y:19; // y coord
signed animation:10; // animation
signed z:19; // z coord
signed padding0016:3;
OP_Consider = 1184
OP_TargetMouse = 0a2d
This is what I have so far

Looks pretty good, at least from a couple minutes of use. Will give more feedback later. Really wish I could help with these struct changes.
