A sequence input that produces a float. A sequence input is a small value object that a sequence action reads, and that some actions also write. Inputs nest: a combined input takes two other inputs as operands, and an input that reads a property of an object takes an object input that finds the object. There are inputs for a float, an int, a bool, a string, a vector, a color, a single object, a list of objects, an attachment, the particle effect of a UI element, and inputs that create an object.

Reading. A read either returns a value or fails. No input caches a result: every read evaluates the whole chain of inputs again from its sources. An action that reads an input on every update re-evaluates the chain on every update. Actions such as SequenceActionLerpFloat fail when a read of one of their inputs fails.

Writing. An action that changes a value, such as SequenceActionLerpFloat, writes each new value through its output input. A write either succeeds or fails. An input that cannot be written fails every write.

Forms.

Form Classes Read Write
Constant SeqInputConst* Returns the stored value. SeqInputConstFloat replaces the stored value.
Object property by slot SeqInputVarCameraFov, SeqInputVarCameraNearClip, SeqInputVarCameraFarClip, SeqInputVarCameraZoom, SeqInputVarAttachment, SeqInputVarUiVfx Reads a property of the object in the Source slot. Writes that property on the object.
Object property by object input SeqInputVarPosition, SeqInputVarOrientation Reads a property of the object that Object returns. SeqInputVarPosition writes the position.
Object property over a list SeqInputLightColor, SeqInputLightIntensityScale, SeqInputLightHdrScale, SeqInputPointLightRadius, SeqInputMaterialParamFloat, SeqInputMaterialParamColor, SeqInputObjectEnabled Reads the property from the first object in Objects that has it. Fails if no object has it. Writes the property on every object in Objects that has it.
Combined SeqInputCombinedFloat, SeqInputCombinedVector, SeqInputCombinedColor and the classes based on them Applies Operation to the reads of LeftSource and RightSource. SeqInputCombinedFloat fails every write.
Object SeqInputSelectorObject, SeqInputGameEntityObject, SeqInputMapPlaceableReferenceObject, SeqInputNearestGameEntityByTagObject, SeqInputGameEntityTagObjectArray Returns one object or a list of objects. None.
Create SeqInputCreateCamera, SeqInputCreateZoomableCamera, SeqInputCreateEffectEmitter, SeqInputCreateSound Creates a new object when SequenceActionCreateObject runs. None.

Objects and slots. A sequence refers to objects through slots. A SequenceObjectSelector names a slot, and the code that starts the sequence puts objects into the slots. SeqInputSelectorObject returns the object in its slot, and the inputs with a Source property read their slot directly. An input fails when its slot is empty.

Objects provide features: a position and orientation, a camera, a camera zoom, a light, sequence material values, an enabled state and attachment. An input that asks an object for a feature that the object does not provide fails.

Operation. The combined inputs read Operation as follows.

Value Name Float result Vector and color result
0 Add LeftSource + RightSource LeftSource + RightSource, per component
1 Subtract LeftSource - RightSource LeftSource - RightSource, per component
2 Multiply LeftSource * RightSource No value
3 Divide LeftSource / RightSource. A divisor of 0 is not checked. No value
other None No value No value

For "No value", the read reports success and writes no result, so the action keeps the value that it held before the read.

Defaults of the create inputs. When one of these input properties is unset, the create inputs fill it with a constant input:

Property Value
Position, orientation (0, 0, 0)
fov 50
nearClip 50
farClip 10000
Zoom 600
EnableOnStart, 0xcae95eff true
scale 1
StartAudioEvent an empty string

SeqInputCreateSound.EndAudioEvent has no default. If it is unset, no end event is posted.
