(Name): [Read-Write]
- add_key(time, new_value, sub_frame=0.000000, time_unit=SequenceTimeUnit.DISPLAY_RATE, interpolation=MovieSceneKeyInterpolation.AUTO) MovieSceneScriptingDoubleKey ¶
Add a key to this channel. This initializes a new key and returns a reference to it.
- Parameters:
time (FrameNumber) – The frame this key should go on. Respects TimeUnit to determine if it is a display rate frame or a tick resolution frame.
new_value (double) – The value that this key should be created with.
sub_frame (float) – Optional [0-1) clamped sub-frame to put this key on. Ignored if TimeUnit is set to Tick Resolution.
time_unit (SequenceTimeUnit) – Is the specified InTime in Display Rate frames or Tick Resolution.
interpolation (MovieSceneKeyInterpolation) – Interpolation method the key should use.
- Returns:
The key that was created with the specified values at the specified time.
- Return type:
- compute_effective_range() SequencerScriptingRange ¶
Compute the effective range of this channel, for example, the extents of its key times
- Returns:
A range that represents the greatest range of times occupied by this channel, in the sequence’s frame resolution
- Return type:
- evaluate_keys(range, frame_rate) Array[double] ¶
Gets baked keys in this channel.
- Parameters:
range (SequencerScriptingRange) –
frame_rate (FrameRate) –
- Returns:
An array of double’s contained by this channel. Returns baked keys in the specified range.
- Return type:
Array[double]
- get_default() double ¶
Get this channel’s default value that will be used when no keys are present. Only a valid value when HasDefault() returns true.
- Return type:
double
- get_keys() Array[MovieSceneScriptingKey] ¶
Gets all of the keys in this channel.
- Returns:
An array of UMovieSceneScriptingDoubleKey’s contained by this channel. Returns all keys even if clipped by the owning section’s boundaries or outside of the current sequence play range.
- Return type:
- get_num_keys() int32 ¶
Returns number of keys in this channel.
- Return type:
int32
- get_post_infinity_extrapolation() RichCurveExtrapolation ¶
- Returns:
Gets the Post-infinity extrapolation state. See ERichCurveExtrapolation for more detail.
- Return type:
- get_pre_infinity_extrapolation() RichCurveExtrapolation ¶
- Returns:
Gets the Pre-infinity extrapolation state. See ERichCurveExtrapolation for more detail.
- Return type:
- remove_default() None ¶
Remove this channel’s default value causing the channel to have no effect where no keys are present
- remove_key(key) None ¶
Removes the specified key. Does nothing if the key is not specified or the key belongs to another channel.
- Parameters:
key (MovieSceneScriptingKey) –
- set_default(default_value) None ¶
Set this channel’s default value that should be used when no keys are present. Sets bHasDefaultValue to true automatically.
- Parameters:
default_value (double) –
- set_post_infinity_extrapolation(extrapolation) None ¶
Sets the Post-infinity extrapolation state. See ERichCurveExtrapolation for more detail.
- Parameters:
extrapolation (RichCurveExtrapolation) – The new extrapolation mode this key should use for evaluating after this key.
- set_pre_infinity_extrapolation(extrapolation) None ¶
Sets the Pre-infinity extrapolation state. See ERichCurveExtrapolation for more detail.
- Parameters:
extrapolation (RichCurveExtrapolation) – The new extrapolation mode this key should use for evaluating before this key.
