* '''val''' is an array of 2 floats. The 1st float is the start ("A") value of the interpolation, and the 2nd float is the end ("B") value.
* '''interp''' is the interpolation mode, which determines how the current value of the interpolation is computed over time, where time starts at 0.0 and ends at 1.0:
** ConstA (0 or 0x48e48e7a) - Always the Astart value.
** ConstB (1 or 0x48e48e7b) - Always the Bend value.
** Random (2 or 0x0fe111bf) - A new random value between the Astart and Bend value, refreshed every '''freq''' seconds.
** Linear (3 or 0xb7353b79) - A value between Athe start and Bend value, found by using linear interpolation.
** Sine (4 or 0x0b326f01) - A value between Athe start and Bend value, found by using sine interpolation.
** Cosine (5 or 0x498d7119) - A value between Athe start and Bend value, found by using cosine interpolation.
** Time (unused, 6) - The current time of the interpolation.
** Unused/Unknown (6)
** Step (7 or 0x0b354bd4) - The Astart value ifuntil time*'''freq''' <>= 0.5, andthen the Bend value if time >= 0.5.
* '''freq''' is the frequency of the interpolation when using Random, Linear, or Step mode.
* Either '''freq''' or '''oofreq''' determines the frequency (scale) of time for the interpolation. '''freq''' is used when the interpolation mode is either Linear or Step, and '''oofreq''' is used when the interpolation mode is either Sine or Cosine. A value of 1.0 means that the interpolation will be the same length/speed as the lifetime, a value of 2.0 means that the interpolation will be half the length/double the speed, etc. When '''freq''' is used, '''oofreq''' is set to 0, and vice versa.
* '''oofreq''' is the frequency of the interpolation when using Sine or Cosine mode.
 
The actual asset is defined by an xParEmitterPropsAsset struct, which inherits xBaseAsset ([[Object Asset]]):
Line 60 ⟶ 61:
 
* '''parSysID''' is the ID of the [[PARS|Particle System]] that the [[PARE|Particle Emitter]] should use.
* '''rate''' is how many times per second a particle is emitted.
* '''rate'''
* '''life''' is the lifetime in seconds of a particle.
* '''size_birth''' is the start size in units of a particle.
* '''size_death''' is the end size in units of a particle.
* '''color_birth''' is the start color of a particle (red, green, blue, and alpha).
* '''color_death''' is the end color of a particle (red, green, blue, and alpha).
* '''vel_scale''' is unknown/unused (all set to 0).
* '''vel_angle''' is unknown/unused (all set to 0).
* '''vel''' is unknown/unused (all set to 0).
* '''emit_limit''' is always -1.
* '''emit_limit_reset_time''' is unknown (usually set to 0 but sometimes not).
 
At the end of the xParEmitterPropsAsset is a list of [[Events#Links|Link]]s.
