general information

• BINACJBOTrigger Volume.oni is level specific. (It can be found in AE/AEInstaller/vanilla/levelX_Final.dat)
• The XML code on this page is based on onisplit v0.9.61.0

BSL support

show trigger activity

debug_triggers = 1 shows tv event and what character enters, stays inside or leaves

Resetting the trigger volume

trigvolume_reset (string tv_name) resets the TV to its preset state. The primary use of this is to re-enable "entry", "inside" or "exit" calls once the TV has been triggered (only necessary if the respective trigger-only-once flags are set of course). Note that some or all the TV functions are disabled at level load, you'll have to enable them manually after resetting the TV.

Removing corpses

trigvolume_corpse (integer tv_id) removes all corpses inside the specified trigger volume.

file structure

The red and blue lines were added to the screenshot in a graphics program, not by debug_triggers. If you have an updated Oni Mac engine, the TVs can be made visible. Used BSL commands: debug_triggers = 1 chr_nocollision 0 1 chr_debug_characters = 1 chr_location 0 x y z

<?xml version="1.0" encoding="utf-8"?>
<Oni>
   <Objects>
       [...]
   </Objects>
</Oni>

[...] means at least one trigger volume. Paste all tv data into there (this includes <TRGV Id="..."> and </TRGV> tag).

BSL bugs and workarounds

String comparison bug

Trigger volumes can call bsl functions. This function can receive a string variable which contains the character name that triggered the trigger volume.

Unfortunately seems there are a bug when comparing this string parameter with another string variable in the BSL. Even if the trigger volume string and the other string are equal when you compare them in BSL it always returns false.

To reproduce the bug you can open "warehouse_level_scripts.bsl" in "EnvWarehouse" folder and replace the t65 function by this one (make a backup of the file first):

   func void t65(string ai_name)
   {
       var string testVar = "char_0";
       
       dmsg(testVar);
       dmsg("char_0");
       dmsg(ai_name);
       
       sleep(100);
       
       if(testVar eq "char_0"){
           dmsg("regular string comparison works!");
       }
       else{
           dmsg("regular string comparison failed!");
       }
       
       if(ai_name eq "char_0"){
           dmsg("trigger volume string comparison worked!");
       }
       else{
           dmsg("trigger volume string comparison failed!");
       }
       
       dprint t65
       if(d6 eq 0)
       {
           message xdoorislocked
           dprint door_is_locked
       }
   }

Load savepoint 1 in chapter 1 and move the character until the door. This function will be triggered. What is the output that you expect? "trigger volume string comparison worked!" right? Wrong it will print "trigger volume string comparison failed!" even though both string variables have the same value.

Possible workarounds

If you need to detect few characters and if all of these are from different teams you can clone the trigger volume one time for each character and call different functions one for each team. This way you make sure you know which character triggered the trigger volume since each character has a unique team and a unique trigger volume function.

Mod Tool addon

trigger volume manager

With OniTools.xsiaddon you can drag'n'drop BINACJBOTrigger Volume.oni into the viewport.

Add or remove TVs, edit position and rotation as if they were real objects. Change size by moving the polygons.

When ready, export the data as BINACJBOTrigger Volume.xml to a folder of your choice.
