spawnable geometry

In Oni's last level, the platform of the big satellite dish can be spawned/deleted from BSL. Characters on it will fall down when the platform becomes deleted (tested long time ago).

If OBOA import is not allowed maybe we can add more such things with the physics.xml and then use the <ScriptId> for BSL?

Possible applications:

• grids in front of ventilation shafts (a little door object should be a good alternative here)
• ground/ceiling/objects for cutscenes that become partially destroyed
• destrucable walls like in Deus Ex 3 (trigger volume, replacing punch anim with punch-through-wall anim)

Perhaps this will help: http://oni.bungie.org/community/forum/viewtopic.php?pid=36765#p36765

In the textures.xml file you can set the environment's collision info by texture.

Also, you can add OBAN in the physics.xml file like this, though I have not fully tested this.

       <Object Name="object_Zipthing01">
           <ScriptId>71</ScriptId>
           <Geometry>M3GMZipthing01.oni</Geometry>
           <Animation>OBANZipthing01.oni</Animation>
       </Object>

If you extract the AKEV for the compound level, the big dish is part of the environment. env_show is used to show and hide the dish. However, currently, OniSplit does not support that feature.

EdT 01:11, 6 June 2012 (CEST)

Okay, i see, another thing to wait for. Will test the physics.xml a bit during weekend. paradox-01 12:08, 6 June 2012 (CEST)

breakable glass with BSL recognition

Not tested.

BSL command:

env_broken (ID_1, ID_N)

It's used in the training level and determines if glass got shot through or not. How do we set such things up?

texture exchange

Not tested.

(OBD:IDXA_AKEV_2)

BSL command supported by PC and Mac:

env_texswap ID texture

Might be useful to switch on/off static and animated textures. (News screen: running or off or smashed. Lava stream: flowing or stagnating or cooled down. Etc.)

AKEV: Akira Environment

Somehow I would like to have the AKEV and ONLV information on one page (like the sound stuff on SNDD). Let's see how this turns out.

AGQG flags - appears to be used by textures.xml <GunkFlags> (just some or all of them ?)

DoorFrame (invisible quad that uses the TXMP_DOOR_FRAME texture)

Ghost (pathfinding volume separator, see AKVA etc)

(Copied from hex page. Is this still up to date ?)

Triangles

Many quads are in fact triangles: the last two vertices have the same PNTA and TXCA entries, and the ARGB color is (255, 205, 205, 205) (80% gray, 100% opaque). There is also a flag specifying that.

Ghost, StairsUp, StairsDown

These flags are used for BNV adjacencies, see AKAA. Stairs up/down are used instead of Ghost when the quad is placed at the bottom/top of the stairs. These quads are not visibile. The script variable env_show_ghostgqs is intended to control the visibility of such quads but it requires "debug" level files.

There are a couple of ghost quads that aren't referenced from AKAA. It's likely that those quads are useless.

DoorFrame

This appears to be another type of "ghost" quad (its visibility is controlled by the same env_show_ghostgqs variable). Sometimes it is used together with the Ghost flag but not always. Only the door frames that also have the Ghost flag are used as adjacencies so it's unclear if the rest of the door frames serve any purpose. In fact it appears that this flag has no effect other than making the quad invisible.

Stairs

This is applied to the invisible ramp quad that covers the stairs. In general this flag is also applied to the visible stairs geometry but there are some exceptions (errors? see level 19 stairs).

NoOcclusion

This flag tells the octtree raycaster to ignore the quad when doing ray/quad intersections. This is tipically used for small quads that are unlikely to affect the overall environment visibility.

ProjectionBit

These 2 flags can be 00, 01, 10 and 11. That means the values 0,1,2 and 3 which have the following meanings:

• 0 - No projection plane specified. One can be computed if needed. Never used in files, may slow down the game if used.
• 1 - Project quad on XY plane.
• 2 - Project quad on XZ plane.
• 3 - Project quad on YZ plane.

The projection plane is used to determine if a point is in a quad (this point is usually the result of an intersection between a ray and the quad plane).

GridIgnore

Appears to be unused. Its likely purpose is to mark quads that don't count as obstacles in the pathfinding grid.

Danger

Appears to be unused. Its likely purpose is to create danger areas in the pathfinding grids. Usually there's a trigger volume nearby that hurts/kills the character. This quads are always invisible.

Invisible

Invisible quads have a couple of different uses:

• block player access to some parts of the environment
• stairs ramp
• collision geometry (used by some "complex" furniture)
• danger quads (see above)
• some other apparently useless quads

Furniture

Set for all quads that belong to a furniture object. It doesn't appear to be used. It is also redundant since all the furniture quads have an object id.

NoDecals

Prevents the creation of decals on the quad. Set for door quads because the decals would disappear when the door opens. That's why shooting a door doesn't leave a mark.

Impassable

Probably used by forcefields and end of level boundaries (like in state archive level).

import

• Import doesn't work with empty skybox tag; <Sky>clear</Sky> helps here. (Or maybe onisplit just wants a name and doesn't care if the resource really exists?)
• triangle limit: ca. 520.000 (500.000 to be on save side)
• visible GQs: ca. 16.000, sooner or later higher numbers will cause render bugs and call BSL message "Exceeded max visible GQs number"

links to free texture resources

• various game textures
• skies and objects of the solar system
• skies
• skies
• CG Textures for 3D
• to be expanded

ideas to test out

None at the moment.

ideas that has been tested

sky dome - it's a fail

sky box

sky dome

Maybe it's possible to create a very big sphere or dome that covers the entire level (and let Oni's skybox unused). If it's doable it could avoid ugly lines of the skybox coming from OpenGL rendering.

Update: 12 June 2012

New issues appeared that need to take care about:

• brightness:

The brightness can be somewhat influenced by BSL commands like with gl_fog_..., gs_farclipplane and must be set adequately.

• texture size:

The dome seen in the screenshot has a texture size of 512x512 and hence looks quite pixelated.

The problem might be solved by splitting the dome into sectors and giving each sector its own texture.

gl_fog_start=.99999

test level over HERE

Update: 14 June 2012

• texture boarder and distortions:

Texture boarders have darker pixels so the UV must not reach them. Also after splitting the textures inside the editor there will be little distortions but they are still noticeable enough to make the sky look odd. Fine-tuning the UVs didn't really help.

• The gs_farclipplane max value makes the size of the dome quite limited: I think that the max radius here is somewhere between 2500 and 5000 world units.

I consider this as a fail. Oni would need bigger view range and a texture support of 2096x2096.

ideas for onisplit

Neo might update OniSplit so that it is searching specific strings in object names of a dae level file.

Cutscene cams

• string "cutsceneN" (e.g. cutscene231) -> OBAN

Doors

• string "door*" (e.g. doorBlastDoorMX2000) -> DOOR + BINACJBODoor + OBAN
  • but if the string is "door*cloneN" then the DOOR and OBAN creation gets skipped (e.g. doorBlastDoorMX2000clone3), only class name, rotation and position get written into BINACJBODoor

Animated objects

• string "*_BeforeAnim": that's first static object with collision data (e.g. BlueCar1_BeforeAnim)
• string "*_InAnim": that's the animated cutscene object (e.g. BlueCar1_InAnim)
• string "*_AfterAnim": that's the second static object with collision data (e.g BlueCar1_AfterAnim)

Fake-destructible objects

• string "*_BeforeAnim": that's first static object with collision data (e.g. ConcreteWall2_BeforeAnim)
• string "*_FragmentN": that's the group of animated cutscene objects (fragments of the static object) (e.g. ConcreteWall2_Frag5)
• string "*_ColFragN": that's the group of static objects with collision data (e.g. ConcreteWall2_ColFrag5)
• string "*_NoColFragN": that's the group of static objects without character collision (e.g. ConcreteWall2_NoColFrag5)
  NoColFrag would be useful if the fragments are quite numerous and small and hence would pose a problem to the pathfinding
