Source code	zEntTrigger.h

This asset defines an entry for a trigger, a volume of space which can detect what happens within it and send events to other assets accordingly.

The triggers have their own position coordinates below, but they use the Position values in the Placeable header as the pivot point for rotation (rotation is done as if that point was the origin). Apparently, all 3 trigger types can be rotated this way.

Format

Triggers are entity assets, so they start with their 0x54 byte header, then are followed by:

Offset	Type	Variable	Description
0x54	struct (size: 0x30)	p
0x54	Vector3	Trigger Position 0
0x60	Vector3	Trigger Position 1
0x6C	Vector3	Trigger Position 2
0x78	Vector3	Trigger Position 3
0x84	Vector3	direction	Usually (0, -0, 1)
0x90	int	flags	Usually 0.
Events
0x94	Event[numberOfEvents]	Events

• Trigger types (offset 0x09):
  • 0 - Box
  • 1 - Sphere
  • 2 - Cylinder (unused)
  • 3 - Sphere (unused, seems to be the same as used Sphere)

• Trigger Position 0
  • Box - Front, Bottom, Left sides of box (absolute coordinates)
  • Sphere - Center (X, Y, Z) (absolute coordinates)
  • Cylinder - Bottom? (X, Y, Z) (absolute coordinates)
• Trigger Position 1
  • Box - Back, Top, Right sides of box (absolute coordinates)
  • Sphere - X is the sphere's radius. Y and Z are always 0.
  • Cylinder - X is the cylinder's radius. Y is the cylinder's height. Z is probably always 0.
• Trigger Position 2
  • Box - Three seemingly random values in the range of 0xCDCDCDB7 to 0xCDCDCDDA. The meaning of this vector is unknown and is probably unused.
  • Sphere - Always (0, 0, 0)
  • Cylinder - Probably always (0, 0, 0)
• Trigger Position 3
  • Box - Three seemingly random values in the range of 0xCDCDCDB7 to 0xCDCDCDDA. The meaning of this vector is unknown and is probably unused.
  • Sphere - Always (0, 0, 0)
  • Cylinder - Probably always (0, 0, 0)
