The bind menu only offers modifiers that fit the field, so you rarely need this list to *find* one. It is here to answer "is there already something for this?" before you write your own. {% hint style="info" %} Almost every parameter listed here can itself be a binding. A clamp whose maximum comes from a difficulty setting is the normal case, not an advanced one. {% endhint %} Every modifier name below links to its full entry: what each parameter does, a worked example, and what happens in the write direction of a two-way binding.

## Numeric Applies to every numeric type: `int`, `long`, `float`, `double`, and the rest.

Modifier	What it does
Math Operation	Add, subtract, multiply, divide and the rest, against a bindable operand.
Math Expression	Evaluates an expression in which the input value is one of the variables. For when a chain of small modifiers would be less readable than one formula.
Clamp Value	Clamps between a bindable min and max.
Normalize Value	Maps a range onto 0 to 1.
Remap Range	Maps one range onto another, with optional clamping and easing.
Absolute Value	Drops the sign.
Modulus Value	The remainder against a bindable modulus.
Snap Value	Quantizes to a step, rounding, flooring, ceiling or truncating.
Evaluate Curve	Runs the value through an `AnimationCurve`. The most direct way to shape a response by hand.

## Boolean

Modifier	What it does
Invert Boolean	Negates it.
Logic Operation	AND, OR, XOR and friends against a bindable operand.
Bool Expression	Evaluates a boolean expression with the input as one of the variables.

## String

Modifier	What it does
Text Template	Builds a string from a template where the input and bindable variables are placeholders, with pipe transforms such as `{x\|upper}` and `{x\|truncate:20}`. This is the string modifier.
Change Casing	Upper, lower, title and so on.
Substring	A slice, by index and length.

{% hint style="info" %} **String Format** and **String Concat** are gone from the menu. Both are deprecated in favour of Text Template and are no longer registered, so they cannot be added to a new binding. Instances already saved in a scene or a prefab keep deserializing and running, and their row in the Inspector offers an **UPGRADE** button that converts them. {% endhint %} ## Colour

Modifier	What it does
Tint Color	Multiplies each channel by another colour.
Color Additive	Adds each channel.
Blend Color	Blends toward another colour with a blend mode and an amount.
Adjust Color	Brightness, hue and saturation.
Set Alpha	Sets, multiplies or offsets the alpha channel.
Swizzle Color	Remixes the channels, for example RGBA to BGRA.
Color Expression	A maths expression per channel, with the input as four variables.

## Vector `Vector2`, `Vector3`, `Vector4` and their integer variants, each with the modifiers that make sense for it.

Modifier	What it does
Add Vector	Component-wise addition.
Scale Vector	Component-wise multiplication.
Rotate Vector	Rotates by an angle in degrees.
Vector Magnitude	Normalizes, clamps or sets the magnitude.
Min Distance, Max Distance, Clamp Distance	Keeps the vector within a distance of a center point.
Swizzle Vector	Remixes the components.
Vector Expression	A maths expression per component.

## Timing and motion These only advance while the binding runs, so they need an update point on a proxy binding, or a repeated read on a `Bind` field. Adding one does not select an update point for you. See [Tweening and Control](/binding-system-3/pipeline/tweening.md) for the details.

Modifier	What it does
Value Delayer	Delays the value by a number of seconds.
Tween Animation	Animates toward the input value using easing functions.
Value Smoother	Follows the input smoothly using damped dynamics. No overshoot, no configuration beyond a smoothing time.
Blend To	Blends toward a target value by a factor.

Available for `float`, `Vector2`, `Vector3`, `Color` and `Quaternion`, depending on the modifier. ## Routing and conditions

Modifier	What it does
Set Value	Sets a value up the chain, ignoring the one it received.
Link To Bindable	Links this binding to another bindable value, in both directions.
Value Events	Routes the value to other bindings and to `UnityEvent`s when it matches, passing it along untouched.
Value Conditions	Tells boolean bindings and events whether the value matches, passing it along untouched.
Numeric Value Events / Conditions	The same, with numeric comparisons.
String Value Events / Conditions	The same, with pattern matching on text.

## Diagnostics and safety

Modifier	What it does
Value Logger	Logs the value flowing through the binding without changing it. Optionally to a file rather than the Console.
Null Check Modifier	Substitutes a fallback when the value is null. Reference types only.
Compound Modifier	Several modifiers presented as one.

{% hint style="success" %} **Value Logger** is often faster to reach for than a breakpoint. Drop it into a binding, watch the Console, remove it. It changes nothing about the value. {% endhint %} ## Getting these for your own types Seven of these are generic in a way Unity cannot serialize on its own: **Set Value**, **Link To Bindable**, **Value Delayer**, **Value Logger**, **Value Events**, **Value Conditions** and **Null Check**. For a type of your own, the package generates them on request.
