Judging from this discovery it seems possible that maybe there are more ONI file types which can have this "used physics" field. For example [[DOOR]], unknown field 0x18 ( is 0x 02|00|00|00 -> reacts on collisions, ignores gravity ). Maybe there are more files with this field ? --[[User:Loser|Loser]] 07:32, 16 August 2009 (UTC) | Judging from this discovery it seems possible that maybe there are more ONI file types which can have this "used physics" field.

:So just checking: when you set this field, the particles suddenly had collisions\gravity and such? [[User:Gumby|Gumby]] 02:31, 17 August 2009 (UTC) | |||
::Same question as Gumby. For all I know particles do not have "physics", only objects and characters have. As for other uses of this "physics type" thing: highly unlikely. I've said it before and I'll say it again: the physics system in Oni is simplistic. There's nothing that it can do more than it already does. Don't waste your time on it. [[User:Neo|Neo]] | |||

;Direction type Inaccurate vs. Cone | |||
:The Inaccurate type was designed for standard ballistic weapons which will have a cone of fire expanding out from the point of origin, therefore it works identically to the Cone type except with an additional factor, "inaccuracy". The "angle" supplied is now a base angle, which is added to by the inaccuracy setting. The "center bias" for Cone and Inaccurate emitters can be positive to pull the dispersion of particles towards the center of the vector, or negative to push them towards the edges of the cone. | |||
:The inaccuracy setting is only used if the originating character is an AI or turret. The AI's or turret's shooting skill is looked up and multiplied by the difficulty setting's weapon inaccuracy multiplier (see [[ONGS]]), then added to the base angle. With the bias taken into account, and some randomization added by the conical dispersion function, this determines the exact trajectory of the bullet coming from the gun. | |||
