Concept phase

Be aware of limitation of level and engine.

  • triangle limit of a game level: ca. 520.000 (500.000 to be on save side)
  • (formerly "XSI") Mod Tool can save dae files with max. 64.000 triangles per object
  • when polygons are too tightly packed the cam will look at too many of them and glitches appear: the visible GQs (GunkQuads) limit is 8192 (2^13), higher numbers will cause render bugs and call BSL message "Exceeded max visible GQs number"; limited solutions to this:
    • decrease the gs_farclipplane_set value
    • hide objects by env_show
    • hide objects by level design
      • for example departments in a building could be quite detailed because the view at the other departments/rooms is blocked by non-transparent walls
  • The camera can look at 2049 transparent textures at once, one more and Oni crashes.
  • characters are visible only within 4099|4099|4099 and -4099|-4099|-4099 world units
  • geometry stops at ca. X=4228|Z=4228 and -4228|-4228 (height not tested)
  • chr_debug_spheres = 1 visualizes collision spheres of characters, then you can check if they fit through a new entrance


Notes on Mod Tool and Google Sketchup

Re-saving a dae file - that was originally made in Sketchup - in Mod Tool can result in a surprising change in size within Oni.

That due to a difference in the length specification.

For example Sketchup dae file has: <unit meter="0.0254000" name="inch" />
Re-saved Mod Tool dae file has: <unit meter="0.1" name="decimetre"></unit>

In that case you would need to open the new dae inside a text editor and change the length specification again.


Level import with OniSplit v0.9.82.0+

Demo files

Demo files can be downloaded here.

First put the new "OniSplit.exe" into the second "lab" folder alongside the xml files.

There's a "build.cmd" file. Those two are the important lines: 

OniSplit.exe -create:level out lab.xml
OniSplit.exe -import:pc out level3_Final.dat

The first line create the *.oni files from a master.xml file, in this case "lab.xml". If final, the oni files can be put into a new AE package.

The second line creates level archives which can be used for fast tests. They don't require you to install a package.

Instead of "nosep" you can now also use "pc" for the import. Mac does still use "sep".

If the game crashes while loading (at ca. 90% progress), be sure that the texture's x and y (pixel) dimension are power of two: 512, 256, 128, 64, etc.

If the game crashes while loading (at ca. 50-60% progress), be sure that the BINACJBOCharacters/AISA file has a player character.

If the game crashes while loading (at ca. 5-10% progress), check if all textures were inside the "out" folder.

You can extract the AKEV file to xml, then search for the TXMP array.
THIS script checks which textures are missing by comparing the AKEV*.xml with its *.oni files folder. Adapt the two paths so that it works for you. Alt + 4, insert code, then F5.

"TXMP_marker_door" and "TXMP_marker_ghost" will be missing in the demo's "out" folder.

You can add this between the other two lines in the build.cmd to prevent a crash. 

OniSplit.exe -create:txmp out env/markers/*.tga


The master xml file

File paths can be either absolute or relative.

The master xml file name determine the bsl folder name and the AKEV and ONLV file name in the output folder.


Mandatory files for level import:

  • level_environment.dae
  • level_bnv.dae
  • level_textures.tga/jpg/png
  • Character.xml or AISA with player
  • ONSK name in <Sky> (can be fake name)
  • ONLD file (for new levels; read on HERE about savegame unlocking)


XML tag content type description
<?xml version="1.0" encoding="utf-8"?> float, flag Ignore this.
<Oni> -
<Level SharedPath="..."> link The master xml file can link to other xml files, most of them are BINACJBO files. The file type gets declared inside the file, so the file name itself doesn't have to contain the type. Ergo, "BINACJBOCharacter.xml" can be given a simpler name like "Character.xml".

Some resources used by those xml files can be found in a "shared" folder. OniSplit copies textures and "physics" objects into the output folder; furniture objects will be integrate into the AKEV. Unused resources in the shared folder will be ignored. That way the final level archive / AE package contains only necessary files which saves the end-user space.

In the demo are various subfolders in shared folder: consoles, doors, furniture, triggers and turrets. Following file types comes there without their file prefixes: CONS, DOOR, TRIG, OFGA. OniSplit recognize them nonetheless.

env_shade Id Id R G B

Static objects store their Id in one of AKEV's IDXA instances.

<Model>

This tag is mandatory (it must be present to avoid errors); the model section contains one import path to the AKEV (level) geometry (*.dae) and can contain additional import paths for exceptions (*.dae).

Data from the demo: 

               <Import Path="env/lab_env.dae"/>
               <Import Path="env/lab_motorcycle.dae">
                   <Node Id="motorcycle">
                       <ScriptId>9</ScriptId>
                       <GunkFlags>NoCollision</GunkFlags>
                   </Node>
               </Import>


env_show

The motorcycle has here script id 9. You can show and hide the object with bsl command env_show whereby the second parameter means true or false. Never use 0 as id because it won't work. 

env_show 9 1
env_show 9 0

EdT demonstrates here env_show. The objects have collision.


The last original level (syndicate mountain compound) has a big satellite dish platform that can be made hidden. Obviously, such objects/areas can be made to have pathfinding too.


More possible applications of env_show
  • 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)
  • grids in front of ventilation shafts (a little door object could be an alternative)
    • at the moment this can't be done because characters can't sneak under the top edge of the opening (the characters collision spheres are too big)
  • managing object groups with trigger volumes (save multiple objects in one dae file)


Breakable glass with BSL recognition

Broken env objects can be recognized by bsl command env_broken (ID_1, ID_N). However, this whole thing requires additional code to work.

An example is the training level. Let's determine how we can set up such a thing.

First we need a trigger volume like in level 1. 

       <TRGV Id="11495">
           <Header>
               <Flags>Locked</Flags>
               <Position>-714.6615 -298 -555.2073</Position>
               <Rotation>0 0 0</Rotation>
           </Header>
           <OSD>
               <Name>tv75</Name>
               <Scripts>
                   <Entry></Entry>
                   <Inside>targets_gone</Inside>
                   <Exit></Exit>
               </Scripts>
               <Teams>255</Teams>
               <Size>400 31 270</Size>
               <TriggerVolumeId>75</TriggerVolumeId>
               <ParentId>0</ParentId>
               <Notes></Notes>
               <Flags>PlayerOnly</Flags>
           </OSD>
       </TRGV>

Now we need some BSL code. 

var int inside_target_function;

func void enter_target_function(void)
{
   dprint enter_target_function
   inside_target_function = 1;
}

func void exit_target_function(void)
{
   dprint exit_target_function
   inside_target_function = 0;
}

func void targets_are_not_gone(void)
{
	# CB: turn off the trigger volume and sleep for a second
	# so as not to cause hideous performance loss
	trigvolume_enable tv75 0
	sleep 60
	trigvolume_enable tv75 1
}

func void targets_gone(string ai_name)
{
	if(inside_target_function eq 0)
	{	
		enter_target_function() # catch other "targets_gone" functions to let them do nothing

		var int num_broken = env_broken(3001, 3018);
		# if you only one target use scheme: env_broke(3001, 3001)

		if (num_broken eq 18)
		{
			targets_are_gone();
		}
	
		if (num_broken < 18)
		{
			targets_are_not_gone(); # to set check interval to one second
		}

		exit_target_function
	}
}

func targets_are_gone
{
	trigvolume_enable tv75 0
	# [...]
}
Explanation

Player enters the TV, "targets_gone" gets
