Magic Casting Interrupted

[kjLotus]

Tried to recreate my issue. This works:
1. Create new character
2. Learn cure as WHM
3. Cast

This doesn't:
1. Create new character and logout.
2. Through SQL, unlock all jobs.
3. Through SQL, set magic skill for healing and summoning.
4. Log in, and cast as WHM or SMN.

when you say "this works" are you referring to the spells working or the act of recreating the issue working?

The spells worked for a small amount of time when creating a new character, leaning the cure spell and casting on myself.

i'll try to remember to attempt to duplicate this tonight

is it on your own private server?

[azafaraht]

Yeah, private server... My guess has always been that I made a mistake somewhere, like mass learning spells through a lua script.

GM command @addallspells doesn't really mess anything up and it adds every single spell at once

my advice, if you really want to find out easily and not make me spend forever trying to replicate it, it to put some breakpoints in the code and step through to see what it's doing

ai_char_normal.cpp, ActionMagicCasting (line 1185) is probably the best spot

if you don't know how, that's ok, i'll try to replicate it ; ;

I used the player:addSpell function, inside a NPC trigger event. That's how I learned all spells.

Thanks for advice and the location of the ActionMagicCasting. Well try now.

Funny, created another character, taru, in sandoria, as black mage. Learned Stone. Went outside with the cute little taru, couldn't finish the casting... Ok, I'll be trying the breakpoint around ActionMagicCasting and will let you know my results. Thanks kjLotus.

I want to printf from the cpp to the dsgame log. How can I achieve this so I can trace my error while casting?

[azafaraht]

I used a ShowDebug statement after each ActionMagicInterrupt call in ai_char_normal.cpp, ActionMagicCasting to find where it is determining that the cast should be interrupted.

Casting is being interrupted here:

Code: Select all

//the check for player position only occurs AFTER the cast time is up, you can move so long as x/z is the same on finish.
//furthermore, it's actually quite lenient, hence the rounding to 1 dp
if (floorf(m_PChar->m_StartActionPos.x * 10 + 0.5) / 10 != floorf(m_PChar->loc.p.x * 10 + 0.5) / 10 ||
                floorf(m_PChar->m_StartActionPos.z * 10 + 0.5) / 10 != floorf(m_PChar->loc.p.z * 10 + 0.5) / 10)
                {
                        m_PChar->pushPacket(new CMessageBasicPacket(m_PChar, m_PChar, 0, 0, 16));

                        m_ActionType = ACTION_MAGIC_INTERRUPT;
                        ActionMagicInterrupt();
                        ShowDebug("Location: %u",7);
                        return;
                }

From what I can understand, in my private server, even though I'm standing and casting, the result of the calculate states otherwise. Hence, why I can never cast.

[kjLotus]

print those numbers. printf will go straight to the DSGame console

printf("startpos x: %f startpos z: %f endpos x: %f endpos z: %f\n", floorf(m_PChar->m_StartActionPos.x * 10 + 0.5) / 10, floorf(m_PChar->loc.p.x * 10 + 0.5) / 10, floorf(m_PChar->m_StartActionPos.z * 10 + 0.5) / 10, floorf(m_PChar->loc.p.z * 10 + 0.5) / 10);

can't really think of any causes for something like this off the top of my head
