ha, I thought I was the only one who was tinkering with it=). I've made some code that makes potions effects refreshable and non-stackable, but never got to release it. There were 2 issues, though - I could only make them dispel self within a second - immediate dispel didn't work with any order of effects, and each time such dispel used a hardcoded line from mssectype.2da appears. If there's no line or there is an immunity to it, then an empty line appears anyway. So I considered it non-suitable for the fixpack. Did you manage to avoid these? I'm too lazy to read your code thoroughly=)

I'm sorry, I ran out of time just after starting this and won't be able to get back to it for a bit.

 

@Gort: I'm not sure what you're meaning with immediate dispel didn't work - I've never had to do anything fancy to get that. Remove SecType, Immunity to String 0 seconds works to prevent strings from running when they ought not, blocking them completely I only know how to do with a mix of global effects or an attached .eff.

 

People have been messing around with this stuff since before I was born :)

 

@A64 Yes, it's all but useless, as there's abbreviated code to illustrate a walkthrough that's unwritten, sorry :help: I didn't even start on dealing with nulling everyone's second favorite .bam or what the SAY off %var% is for. I'll get back to it.

 

Didn't mean to reach for your thunder on your Real Dalestyle .exe patch by the way, Sleep is just something people've been talking about ;)

No need for apologies. Take my thunder as you like it, I am totally supportive of, and much prefer, patches that don't require smashing bits and pieces of the .exe up. ;)

For a moment I was wondering who written such an unhelpful tutorial, hee. Yes, sorry - I'd forgotten this thread existed.

 

It's been a staple technique in my Frowny Face Empire for a couple years now, and I'm not quite vain enough to assume other people aren't using it as well.

 

What's giving you trouble? For the simpler uses there are only three things you need to do.

 

Add the new secondary type to msectype.2da, sequentially. Brief/ugly/unweird code:

COPY_EXISTING msectype.2da override
 COUNT_2DA_ROWS 2 rows
 INSERT_2DA_ROW rows 2 ~ImprovedInvisibility stringdisplay~
 REPLACE ~\bstringdisplay~ @1 // @1 = ~Improved Invisibility removed~
 READ_2DA_ENTRY rows 1 2 ImprovedInvisibilityRemovalString
 SET ImprovedInvisibilitySectype = rows - 1
UNLESS ImprovedInvisibility

 

Then add in two new effects at the beginning of each extended header of each spell that's participating in this tomfoolery.

 

The first of these is a zero duration immunity to string display, preventing the "Improved Invisibility removed" string from running iff there's not already some kind of Improved Invisibility active. Set the power level to greater than what the next effect will be removing, at least for now - there are tricksier ways to do this involving external resources. Since you've just added that string to the .tlk, a

WRITE_LONG effect_offset + 0x30 * effect_number + 0x04 ImprovedInvisibilityRemovalString

needs adding under your COPY to override.

 

The second effect you add is a remove by secondary type (opcode 221, I think?). Set the highest level removed to the highest power level you need to knock off (for Improved Invisibility, that'd be seven, so you can avoid cumulativity with Mass Invisibility).

WRITE_LONG effect_offset + 0x30 * effect_number + 0x04 7

You need also to add in what the new dynamically secondary type is:

WRITE_LONG effect_offset + 0x30 * effect_number + 0x08 ImprovedInvisibilitySectype

 

The third and last step is changing the secondary type in the spell header of whichever spell you're copying to the new one you've added:

WRITE_BYTE 0x27 ImprovedInvisibilitySectype

 

And that's it, pretty much.

 

/edit

 

Actually, if you just want Improved Invisibility, skip the string display prevention entirely - that's not one of the places it'll matter, I think.

I should have been reading this earlier, but in case you are still around, Nythrun I have been unable to make this work.

 

I have tried using #101 protection from opcode (set to opcode #139) as well as #267 protection from display specific string, but none of this prevented a string from being displayed when I dispelled the sectype.

 

I have had trouble with this for years, and I hope it is me missing something rather than the engine being uncool.

A small bit of my knowledge - there is no need to update msectype.2da, secondary types seem to work perfectly with or without it (they did for).

 

Yes, they will. However it makes it harder for mods (or anything else) to find a unique secondary type to use, as it would mean scanning all games files. However, as some secondry types are hard-coded and do not appear in msectype.2da anyway...
