Unity Utilities

Utilities to improve the C# experience in Unity: ranging from more capabilities to shorter code length!

For now, to use this library, you need to copy the repo (or download it) and build a .dll file in Visual Studio, Jetbrains Rider or any .NET IDE, to then add it to your Unity project! Alternatively, you can also copy all the scripts in your project :) Don't forget to add the UnityUtilities namespace!

OpenUPM

You can now install this as an UPM packge through OpenUPM! Here's the package page :D

Just open a terminal within your project and type:

openupm add com.amp.unityutilities

or, manually install it through the package manager like this!

C# Version

Currently frozen at #8.0 for backwards compability with Unity 2020.3 and above!

Patterns

A series of popular programming patterns, implemented in easy to use classes!

Singletons

Through the controversy of using them, here are generic, base Singleton classes to get you up and going if you need them!

Since Unity is singlethreaded, none of the following are thread safe!

• Singleton → Generic singleton class, made for MonoBehaviours.
• SingletonPersistent → Generic persistent singleton class, made for MonoBehaviours. Persists through scene reloads.
• SingletonLazy → Generic lazy singleton class, made for MonoBehaviours. Creates itself, if it doesn't exist.
• SingletonService → A newer kind of a C# (doesn't interact with Unity) Singleton, only accessible through method calls. Mainly used for services.

Coroutines

• WaitUntilAndForSecondsRealtime → Suspends the coroutine execution for the given amount of seconds using unscaled time and until the passed condition is true.
• WaitUntilOrForSecondsRealtime → Suspends the coroutine execution for the given amount of seconds using unscaled time or until the passed condition is true.
• WaitWhileAndForSecondsRealtime → Suspends the coroutine execution for the given amount of seconds using unscaled time and while the passed condition is true.
• WaitWhileOrForSecondsRealtime → Suspends the coroutine execution for the given amount of seconds using unscaled time or while the passed condition is true.

Extensions

Numerals

• Round → Rounds float and returns float; number of decimals can be specified.
• RoundToInt → Rounds float and returns int.
• Abs → Returns the absolute value (of ints and floats).
• Clamp → Clamps float or int to the supplied range.
• Map → Maps a float from the supplied range to the supplied range (for floats and ints).

Movement

• GoUp → Smoothly translates the gameobject (or transform) up at the desired speed (float).
• GoDown → Smoothly translates the gameobject (or transform) down at the desired speed (float).
• GoLeft → Smoothly translates the gameobject (or transform) left at the desired speed (float).
• GoRight → Smoothly translates the gameobject (or transform) right at the desired speed (float).
• GoForward → Smoothly translates the gameobject (or transform) forward at the desired speed (float).
• GoBackward → Smoothly translates the gameobject (or transform) backward at the desired speed (float).
• FollowMouse2D → Smoothly makes the Rigidbody2D follow the mouse position at the desired speeds (float, float).
• FollowObject2D → Smoothly makes the Rigidbody2D follow the specified object (or transform) at the desired speeds (float, float);

Vectors

• Round → Rounds Vector2, Vector3 and returns a rounded vector with the specified number of decimals.
• RoundToInt → Rounds Vector2, Vector3 and returns Vector2Int.
• Clamp → Clamps the components of the Vector3 between supplied values.
• VectorFromAngle → Returns the corresponding vector to the given angle (in degrees or radians).
• RotateByAngle → Rotates the Vector2 by the given angle (in degress or radians). This method assumes +X axis is 0 degrees/radians.
• AngleFromVector → Returns the positive angle in degrees (or radians) of given Vector2. This method assumes +X axis is 0 degrees/radians.
• TransformTo2DVector3 → Transforms Vector2 into Vector3 respecting Unity's coordinate system (so x = x, y = 0, z = y).
• ChopTo2DVector3 → Takes and returns a Vector3 respecting Unity's coordinate system (so x = x, y = 0 (or specified), z = y).
• ToVector2 → Transforms a 2-big float array to a Vector2.
• ToVector3 → Transforms a 3-big float array to a Vector3.
• ToArray → Transforms a Vector3 or Vector2 to a 3-big or 2-big float array, respectively.
• GeoDistanceTo → Calculates distance between two coordinates.

Quaternions

• AverageQuaternions → Returns the average of the Quaternions.
• AverageQuaternionsFast → Returns the average of the Quaternions, without normalizing to save on speed.
• Normalize → Normalizes the Quaternion.
• Inverse → Inverses the Quaternion.
• InverseSign → Inverses the sign of the Quaternion.
• IsClose → Checks if the Quaternion is close to the given one.
• Scale → Scales the Quaternion.

GameObject

• Print → Cleaner way of Debug.Log() with log type support
• DelayAction → Delays supplied action by specified number of seconds (float).
• IsAnimatorPlaying → Checks if the animator is currently playing an animation.
• Destroy → More elegant way of writing Destroy(gameObject).
• DestroyImmediate → More elegant way of writing DestroyImmediate(gameObject).

CustomBehaviour

• Log → Logs a message to the console with the object's name.

• LogWarning → Logs a warning to the console with the object's name.

• LogError → Logs an error to the console with the object's name.

• static Log → Logs a message to the console with the passed object's name.

• static LogWarning → Logs a warning to the console with the passed object's name.

• static LogError → Logs an error to the console with the passed object's name.

Miscelleanous

• Flip → Flips a 2-big float array, so that the values swap indexes.
