[General] whats up with "art - orientation interpolation"

[doom_sheep]

this controls how fast units turn visually. however all numbers give weird results. google doesn't find results either.

any idea what number to use for what effect? particularly for making units turn as fast as possible.

I have no idea what this does. But fot make a unit turn faster there is another field in OE. Also there is the bone_head + unit facing trick to make it turn istantly

 

[doom_sheep]

turn rate controls the actual turning, effectively making the unit walk backwards if OI is set in a funny way. it's not what I want. I dunno what bone_head is.

 

[wc3neverdies]

The bone_head trick, if you change a model bone that is connectded to the whole body and rename it as bone_head, hten you can use the make unit face something function to make it turn istantly.

DSG said that units instantly reach the maximum rotation rate at desired facing when Orientation Interpolation is set to 0. At 1, units can instantly reach half rotation rate. Starting with 2, it becomes some kind of rotation rate acceleration/deceleration mechanic.

By the way, I think wc3neverdies is talking about the World Editor script 'Lock body-part facing', which can be used with certain nodes in models ('bone_head', 'bone_chest') to make the unit turn instantly (Likewise, turreted buildings can use 'bone_turret' to automatically aim only the turret at their target).

I suppose I would need an edited model to do this trick, then? bodypart facing also seems to require a second unit and face it constantly rather than be a one-time thing.

DSG said the same thing I did which is that no one knows what actual effects OI will have for most numbers.

The rotation rates I mentioned were measured in game by polling the unit rotation at a high frequency. I also discovered that it updated every 0.03 seconds.

that doesnt really tell me anything practical

Next to how one could measure it to try to discover in more detail how the property works. Given enough data points one could possibly find the maths that control it when it is acceleration based.

this field affects unit's visual turning only, real turning is indifferent from this
any value translates into a table's row index

where first column stands for start turning speed value;
second column for increment per tick to the turn speed;
3rd column stands for max radians turn speed, when (starting + increments*tick) >= 3rd column, it's limited with that value
and 4th dunno exactly, must be finishing turning speed decrease

i have no idea how values from editor converted into these, but obviously slow orientInterp causes disagreement with the real turn speed, allowing to move backwards, for instance
mind that's purely visual thing which has no effect on gameplay
given the last 7 values are all the same copies, there are only 8 levels for orientInterp

 

[doom_sheep]

can you edit the table?
