[BETA/RELz/WIPz] NifSE v1.0 : IV - Oblivion

» Wed Mar 30, 2011 12:21 am

Sorry, you're right; switch what I said about NiAVObject to NiObjectNET.

Basically, here's the deal: the various nif block types derive from one another, so that every NiMaterialProperty is a type of NiProperty, which is a type of NiObjectNET, which is a type of NiObject. You can use any NiObject, NiObjectNET, or NiProperty function on it, because in addition to being a NiMaterialProperty, it is also one of those other things also. Since the name field is defined in NiObjectNET, NiMaterialProperty doesn't redefine it - it inherits that from NiObjectNET. So there is no NiMaterialPropertyGetName function - and never will be. You access that information through NiObjectNETGetName. Same for NiAVObjects (which derive from NiObjectNET), NiNodes (which derive from NiAVObject and thus from NiObjectNET), etc. etc.

Here's a tree that shows the relationships:

NiObject
- NiExtraData
  - NiBinaryExtraData
  - NiBooleanExtraData
  - NiFloatExtraData
  - NiIntegerExtraData
  - BSXFlags
  - NiStringExtraData
  - ...
- NiObjectNET
  - NiAVObject
    - NiNode
  - NiProperty
    - NiAlphaProperty
    - NiMaterialProperty
    - NiStencilProperty
    - NiTexturingProperty
    - ...
  - NiTexture
    - NiSourceTexture

Thus, every block can have NiObject functions used on them, NiNodes can have all NiNode, NiAVObject, NiObjectNET, and NiObject functions used on them, etc. NiExtraData and NiProperty are actually identical to NiObject and NiObjectNET, respectively, but it's important that only a subset of blocks derive from them (the various Ni_____ExtraData and Ni_____Property blocks all define individual features and functions).

Here's a function that goes through NIF and prints the name of each child's Material property (if any).

scn DWnifMaterialTestshort nifIDshort blockIDarray_var childarray_var childrenshort NiMaterialPropertyIDstring_var matNameBegin _GameMode ; compiler override - only necessary, for NifSE, if you're using functions that accept array arguments.    if ( !NiMaterialPropertyID ) ; if not NiMaterialProperty - effectively a doOnce since we'll set it right after this        let NiMaterialPropertyID := GetNifTypeIndex "NiMaterialProperty" ; caching this because GetNifTypeIndex is slowish        let nifID := NifOpen "something.nif" ; open a nif as read-only        let children := NiNodeGetChildren nifID ; optional blockID omitted, defaults to 0 or root        foreach child <- children ; each child is a NiAVObject of some kind            let blockID := NiAVObjectGetProperties NiMaterialPropertyID nifID (*child)            if ( blockID > -1 ) ; returns -1 if it didn't find the property                let matName := NiObjectNETGetName nifID blockID            else                let matName := "No Material"            endif            Print matName        loop    endifEnd

Does that help somewhat?

» Wed Mar 30, 2011 3:38 am

that helps, still one bit i dont understand, these two lines.

        foreach child <- children ; each child is a NiAVObject of some kind             let blockID := NiAVObjectGetProperties NiMaterialPropertyID nifID (*child)

I havent used foreach loops before....only while loops.....that may have something ot do with what i dont understand. I copied what you put there, but it stops the script dead (aka, the script stop running altogether) when it reaches the foreach loop.

» Wed Mar 30, 2011 3:37 am

Could I see NifSE.log?

» Wed Mar 30, 2011 6:03 am

Okay, i forgot to get rid of the nifopen line in yours....thats what cause the script to halt, sorry.

So its running....sort of....its saying there is a skin material on every mesh,

here is the nifse log:

Ack, sorry, typo on my part. I meant NiAVObjectGetPropertyByType not NiAVObjectGetProperties. Try switching that (same argument list).

» Wed Mar 30, 2011 10:17 am

Well that's not good... I'll have to play with that some in the morning to figure out what that is. Definitely a bug there, but hard to say exactly what since we're not getting any further messages...

» Wed Mar 30, 2011 1:06 pm

Apparently, NiAVObject::GetPropertyByType (the Niflib function) crashes if there are no properties. It shouldn't, and looking at the code I don't see why it does, but I can easily just check the size of the property list before calling that function to remove that problem. Next version (probably out tonight or tomorrow) should fix that. Gonna report that as a bug to the NifTools guys...

EDIT: Of course, you yourself could do the same thing by calling NiAVObjectGetNumProperties on it before calling NiAVObjectGetPropertyByType.

» Wed Mar 30, 2011 5:21 am

Okay....this foreach thing is completely throughing my off...

How does it work? Hows does the NiAVObjectGetPropertyByType know what block it is looking at? Im assuming it is to do with the (*child) bit on the end, but what does that do?

I opened up the nif log after putting in the NiAVObjectGetNumProperties check, but it just checked the first block over and over rather then going through the other ones.....the trouble is I dont know how to tell it to look at each block.

» Wed Mar 30, 2011 9:25 am

OK, your code should look like this:

scn DWnifMaterialTestshort nifIDshort blockIDarray_var childarray_var childrenshort NiMaterialPropertyIDstring_var matNameBegin _GameMode ; compiler override - only necessary, for NifSE, if you're using functions that accept array arguments.    if eval ( !NiMaterialPropertyID ) ; if not NiMaterialProperty - effectively a doOnce since we'll set it right after this        let NiMaterialPropertyID := GetNifTypeIndex "NiMaterialProperty" ; caching this because GetNifTypeIndex is slowish        let nifID := NifOpen "something.nif" ; open a nif as read-only        let children := NiNodeGetChildren nifID ; optional blockID omitted, defaults to 0 or root        foreach child <- children ; each child is a NiAVObject of some kind            if eval ( NiAVObjectGetNumProperties nifID (*child) )                let blockID := NiAVObjectGetPropertyByType NiMaterialPropertyID nifID (*child)                if eval ( blockID > -1 ) ; returns -1 if it didn't find the property                    let matName := NiObjectNETGetName nifID blockID                else                    let matName := "No Material"                endif                Print matName            else                Print "No properties"            endif        loop    endifEnd

All (almost all) NifSE functions have the following syntax:

(returned value) NiBlockTypeGetSomething nifID [blockID](bool) NiBlockTypeSetSomething newValue nifID [blockID]

In both cases, the blockID argument is optional; it defaults to 0. The blockID refers to which block within the Nif we're talking about; 0 is the root block (always a NiNode), so when you're talking about the root, you don't need to include that argument (e.g. when you call NiNodeGetChildren nifID above, you're talking about the children of the root; other blocks can have children of their own, if they're NiNodes). In the case of our NiAVObjectGetNumProperties and NiAVObjectGetPropertyByType calls, we're not talking about the root's properties (which it could have, since NiNode derives from NiAVObject), but rather the properties of each of the children. NiNodeGetChildren returns an array of blockIDs that refer to each of the children; when we use foreach child <- children, in each loop child is a map containing { "key"::#, "value"::blockID }, and using *child is equivalent to child["value"] and thus returns the blockID for that child. The number under "key" refers to which child this is (i.e. 0 for the first one, 1 for the second one, etc.)

Does that help? You really should read up on the foreach loop; that seems to be the biggest problem here.

» Wed Mar 30, 2011 6:01 am

Yep, okay i did put it in right, just used your way of writing it and got the same results.

I copied and pasted that and it worked fine. Do you have the compiler override enabled (i.e. _GameMode instead of GameMode)?

Updated to beta 4; new save system is in place and the NiMaterialProperty and NiStencilProperty functions have been added.

This tool has fantastic potential. I had some success running Unnecessary Violence with the dummy NifScript and NifSE 1.0 b3. Dual wielding and throwing seem to work fine.

There were two problems however (haven't tested yet with b4 to see if they're already solved):
- If I saved with a weapon switched to my off-hand (in this case an ayleid battleaxe from KOTN), on game load it would always revert to the longsword mesh.
- Even after disabling Unnecessary Violence I could still see in the console that NifSE was loading meshes, for "mod 255". I think it was saving them, too. This sounds like savegame bloat if you can't get rid of the NifSE meshes a mod created by removing it from your load order.

Gabba: the unnecessary loading is why those functions that UV uses are deprecated. NifSE has absolutely no way of knowing if they're still necessary or not, so it keeps them. The bloating should not be very serious, however - not very much data is saved per mesh. Frankly, I don't particularly wish to continue to support those functions, and writing some kind of utility to instruct NifSE to forget about them does not strike me as a particularly worthwhile use of my time. I've already "wasted" enough time as it is making sure that I haven't completely broken those functions.

As for the load issues, that's... it actually sounds like a UV problem, not a NifSE problem. I'm not certain. Would you mind including NifSE.log (after a game session that includes both a save and a load, preferably)? I know on my end, I can save meshes created by those deprecated functions and load them up correctly (though if you call a deprecated function [or NifOpen or NiNodeCopyChild] on a NifSE-modified mesh, it won't load correctly in beta 3 - that's why I rewrote things for beta 4, since going forward that situation becomes more and more likely).

I've reinstalled UV and NifSE b4, and reverted to a save before I installed it and NifSE b3. But I haven't been able to reproduce the bug. This time items loaded fine, but testing conditions were not exactly the same: I've uninstalled Knights of the 9, and this time the weapons I used were either from vanilla or OOO. Maybe the problem was related to the Knights.bsa? I've read in the DR6 thread that NifSE has had problems loading from bsas.

In any case I'm done testing this for now: UV has several other bugs besides what I described, it conflicts with my hotkey mod, and so on. Too bad since it's really close to integrating well in the game world; hopefully Hex will return soon with a new version!

Beta 3 fixed all of the problems you read about in the DR thread. Was the weapon a longsword before you started?

Beta 3 fixed all of the problems you read about in the DR thread. Was the weapon a longsword before you started?

Good to know that the problems are fixed. I'm not sure I understand your question so I'm gonna summarize everything (I missed some details in my descriptions above):

Test #1:
- Installed: UV, NifSE b3, OBSE 20b4 or b5
- I cleaned the UV esp, which removed a few identical to master records
- When switching a (two-handed) Ayleid Battleaxe from Knights of the Nine to off-hand, and saving and exiting the game, on next load it would have the same name, but with the mesh/texture of a vanilla elven (long?)sword (sorry, I was mistaken when I said plain longsword above).

Test #2:
- Installed: UV, NifSE b4, OBSE20b5
- I reverted to the original (non-cleaned) UV esp, just in case.
- Tried to reproduce the bug with some single-handed weapons I had on hand (from vanilla and OOO), but this time loading/saving worked fine.

Too many parameters changed to make the test conclusive, I know, but the game was crashing way too often, and I got tired of testing. If someone wants to take it up and do more test, he has my blessing.

Yeah, there's basically no way from my end for the type of weapon to change. That sounds like UV replaces your weapon with a special weapon whose mesh it updates to match whatever you had before (except with the handedness changed), and whose default mesh is the Elven Longsword. For some reason, it seems the change to that weapon (from the default Elven Longsword to battleaxe) wasn't saved, but that's not a NifSE thing.

OK, beta 5's up. I'm strongly considering releasing v1.0 final as exactly what's in beta 5 after some testing by you guys, because there've been an insane number of things added and the obvious things left on my to-do list are going to take longer. Please speak up if you have any requests that you'd like to see happen sooner rather than later!

Also, I finally updated the CS Wiki with documentation for all of the new functions. Ugh, that's so tedious.

Um, unfortunately don't have the time to test anything, but stumbled upon a commands that sounds interesting: Does http://cs.elderscrolls.com/constwiki/index.php/NiNodeCopyChild allow to copy stuff (or even the whole thing) from one nif to another?

If so: :intergalactic:
:twirl:

It does. For example, http://img.photobucket.com/albums/v238/DragoonWraith/Oblivion/NifSE/ScreenShot8.png is a picture of my assistant showing off a NifSE-made combination of Steel Dagger scaled to half size and translated 20 units on the Y axis, and the Wooden Rod model I made for Magickal Arsenal way back when.

Topic's a bit dusty, but I've got a question and an idea. What is the chance that EGM files for NIFs can be injected forcefully? Like if you have a piece of headwear that's assigned to the Head or Tail slot and you made an EGM for it, can Oblivion be forced to read that data and conformulate that mesh to match the head shape?
