Parameter Parsing
Strings may be passed into the "Parameters" input on Simple, Expert, and Minimal iTween operations.
Anatomy of an iTween Parameter
Each parameter has four elements, from left to right: The key, the assignment operator (or equals sign), the value and the punctuation (or semicolon).
-The key tells the parser which variable in the iTweenEvent to change.
-The assignment operator tells the parser that the command part is finished.
-The input is what the variable will be changed to.
-The punctuation tells the parser that the value part is finished and this parameter is complete.
Example: "name = New Tween; vectorFrom = this; vectorTo = (10, 50, 100); time = 3.5;"
Keys are case-insensitive and space-agnostic, so "name," "NAME," and "Na Me" will all have the same effect. Values are not case-insensitive, so names should be input with the actual capitalization you want. Numeric values like "float" and "vector" are space-agnostic, but lettered values are not, i.e. "name."
Punctuation at the end of the last parameter in a string is not required, but is considered a best practice.
Parser Arithmetic
For numeric values, arithmetic operations are not parsed with one exception: one single multiplication operation per value. This allows for vectors and rotators to be easily multiplied, but also works for floats and other numeric values.
Keywords
Consider that vectors, rotators, and vector2D keys can take lettered values such as "this," "current," "zero" and "one."
Example: "vectorfrom = this * 2; vectorto = one * 5;"
In this example, the from vector will be the object's current location multiplied by 2 and the to vector will be (5,5,5).
"this" OR "current" will return the object's current vector, rotator, or vector2D.
"zero" will return (0,0,0) or (0,0) for vector2D.
"one" will return (1,1,1) or (1,1) for vector2D.
Parser Grammar
Vectors, Vector2Ds, Rotators, and Linear Colors can be written with parentheses (), braces {}, brackets [] or nothing at all as long as the values are separated by commas (,).
Converting these values to string through the engine is also allowed into the parser. For example, converting a vector (9,7,8) to string will produce "X=9 Y=7 Z=8". The parser will recognize these without issue.
Linear color values can be input as 0-to-1-based RGB vectors or one of the following named colors: black, blue, cyan, green, magenta, red, white, and yellow.
Object references can be set by FName. These object reference keys include onstarttarget, onticktarget, onlooptarget, oncompletetarget, and orientationtarget. Note that the custom curve used as an EaseType cannot be set through the parser.
Variables in the Parser
Variable names may not be passed as a value because they can not be parsed from a string. In Blueprints, best practice is to use the "Format Text" node and convert your variable into text (or in some cases to string then to text) then convert the "Format Text" node's output into a string. Readings from string conversions will be understood by the parser. For C++ users, best practice is as follows:
("vectorfrom = this; vectorto = " + vectorVariable.ToString() + "; time = 5")

tickwhenpaused
Sets whether or not an actor will continue to tween even with the built-in UE4 "Pause" function enabled. Leaving this option set to "false" will respect whatever setting is currently set for the object with regards to "Tick When Paused." Setting it to true will leave it set to true on the actor for now.
Ex: Actor Move From/To, Component Rotate From/To
twp
true OR false
tickwhenpaused = true;
twp = true;

ignoretimedilation
If enabled, the tweening object will have a time dilation that is the inverse of the global dilation.
This is useful for when you use global time dilation modulation for slowdown effects or for pausing but you want the tween to function normally.
The original time dilation will be restored after the tween completes or is stopped.
Ex: Actor Move From/To, Component Rotate From/To

ot
object FName
orientationtarget = My_Character; ot = Table;
nullptr
splinecomponent
If performing a spline operation, you may use this key to specify a spline component by name. Takes an object FName as a value.
spline
object FName
splinecomponent = SplineComponent1; spline = coilSpline;
nullptr
interpolatetospline
If performing a spline operation, sets whether or not the object will interpolate from its current position/rotation to the beginning of the spline position/rotation. If disabled, the object will snap to the start spline position/rotation.
Ex: Actor Move To Spline Point, Component Rotate To Spline Point
its
true OR false
interpolatetospline = true;
its = true;
false
switchpathorientationdirection
If performing a spline operation and LoopType is pingpong/back-and-forth, this will determine whether or not the object will look back during its pong/back travel.
Ex: Actor Move To Spline Point, Component Rotate To Spline Point
its
true OR false
switchpathorientationdirection = false;
spod = false;
true
destroysplineobject
If performing a spline operation, this will destroy the actor that contains the spline component used in the operation. This should only be used when creating procedural splines using GenerateSplineFromVectorArray or GenerateSplineFromRotatorArray.
Ex: Actor Move To Spline Point, Component Rotate To Spline Point
destroysplineobject
OR destroyspline OR dso
true OR false
destroysplineobject = true;
dso = true;
false
shortestpath
Will use find the shortest path between current rotation and the target rotation. Will avoid Gimbal Lock, but will not rotate more than is necessary to reach a rotation between 0 and 359 degrees.
If disabled, 0 to 540 degrees will get you 3 full rotations; enabled will only get you one.
Ex: Actor Rotate From/To, Component Rotate From/To
short
true OR false
shortestpath = true;
short = true;
false
easetype
Determines how the object will ease in or out of its tween. See table below for more information.
ease
see table below for easetype values
easetype = easeinandoutback;
ease = ioquad;
EaseType::Linear
timerinterval
Sets the interval, in seconds, at which the tween will update.
0 will make the tween operate on the tick function. Values greater or less than 0 will operate at the designated interval.
You may add "fps" into the value to make the tween run at a fixed framerate. This works by setting timerInterval to 1 divided by the numerical value when "fps" is found in the value.
interval OR ti
1 OR 1.0 OR
1f OR 1.f
timerinterval = 0.5;
interval = 30fps;
ti = 0.016;
0
EaseTypes
With iTween, users can modulate the transform of their tweens to give them a different look. "In" refers to the beginning of the tween. "Out" refers to the end of the tween. "Ease In Quadratic" will produce a natural, slowed ease at the beginning of the tween and end more quickly. Try out different easetypes to get a feel for how they look. Generally, most users opt for "EaseInAndOutQuadratic" for single-motion tweens because it has the most natural look to it.
Values in this table are listed by the order that they are listed in the "EEaseType" enumeration.
Quadratic, Cubic, Quartic, Quintic, Circular, Sine and Exponential all perform the same type of animation more or less: a smooth push to the destination with a shorter or longer ease. Because of this, I will not be writing descriptions for them.
Note that the Elastic, Bounce, Back, Punch and Spring EaseTypes, also known as Out-Of-Bounds EaseTypes, do not currently work properly with spline operations. They won't cause crashes, but they won't look right because they work by running data through an equation. Splines only go from 0 to the specified spline "duration," so if the equation returns a negative number or a number greater than the spline's duration, the equation ends up clamped. This is being investigated for a fix, but as of now we have no announcements.
