Class Documentation

Edit documentation

A float updater that returns how far the unit has turned since the current turn started, in degrees, limited by how far its facing still lags behind its movement. The sign gives the side of the turn: positive when a unit that faces +Z turns toward +X. Shipped graphs use it in the Turn clip, a ParametricClipData that blends turn animations for different angles.

Turn tracking. A graph that uses a turn updater in any clip turns on turn tracking for the unit. The turn updaters are this one, TurnAngleRemainingParametricUpdater, TotalTurnAngleParametricUpdater and IsTurningParametricUpdater. Turn tracking runs on every movement update of the unit, and only while the unit moves:

• The facing of a moving unit does not snap to the direction it moves. On each update it turns toward the direction of the last movement by a share of the difference, so a change of direction takes several updates.
• When the facing is more than 10 degrees away from the direction of this update's movement, and the last turn started more than 0.25 seconds ago, the client plays the clip named Turn. Each play starts a new copy of Turn and of every clip under it.
• While the facing stays more than 10 degrees away, Turn is played again every 0.25 seconds.

Without a turn updater in the graph, the client does not play Turn by itself and the turn angles stay at 0.

The value over one turn.

1. On the update that starts the turn: the rotation of the facing in that update.
2. After that: the rotation since the turn started, but never more than the cap, which is the latest angle above 10 degrees between the facing and the direction of movement. The cap shrinks as the facing catches up, and the rotation grows, so the two meet around the middle of the turn.
3. When the value reaches the cap, the turn is marked finished.
4. Once TurnAngleRemainingParametricUpdater is 5 degrees or less, the value is only the rotation of the last update, close to 0.

Which clips follow the value. An updater on the Turn clip itself follows the live value only while its copy of Turn is the newest one and the turn is not finished. After that it keeps its last value. A turn is also finished when the unit stops moving. Updaters on clips under Turn, and on clips with other names, follow the live value on every frame. This applies to all four turn updaters.

Notes

• Shipped graphs play Turn on a track of its own, named TURN, with a lower mPriority than the full-body track. The game asks for Run again on every update while the unit moves, so a Turn clip on the track of Run is replaced on the next update.
• Each play of Turn is a new copy, so a ConditionFloatPairData hold or a kPlayOnce child under Turn starts again with each play.
