Development

Debugging Scripts

• DetectLeaks - a simple GUI script for displaying the amount of objects currently loaded by type
• DebugConsole - A script to allow scrolling feedback from your scripts.
• DebuggerX - A simple javascript singleton that allows you to send debug to the console or the GUI
• DrawArrow - builds upon Debug.DrawRay() to add arrowheads at the tip
• Profiler - a simple c# script for profiling the performance of scripts, based on tags
• Reporter - a simple delayed action system info script that could be used for support purposes
• UUnit - a Simple xUnit framework that can be run inside Unity.
• SharpUnit - a unit testing framework adapted from UUnit but written in C#. Can also be run inside Unity3D.
• NUnit - de-facto standard for unit testing in .NET

Performance Scripts

• StaticPerformanceOptimization - A script that optimizes performance statically based on the users graphics card by dropping terrain resolution and quality settings
• SpriteManager - A script that allows many independently-moving 2D sprites to be drawn using a single draw call. This is particularly useful to increase iPhone performance.
• CombineSkinnedMeshes - A Script that allows to combine multiple skinned meshes to just one SkinnedMeshRenderer. Useful for Avatar System!
• SkinMeshCombineUtility - Script to work with CombineSkinnedMeshes.
• CombineChildrenBones - Similar to MeshMerger, this script combines MeshFilter meshes into a single skinned mesh and then tracks transform changes

Character Controller Scripts

• A* Pathfinding - An A* pathfinding-system for out-of-the-box pathfinding in Unity.
• AimDownSights - An expansion script for the FPSWalker that smoothly animates aiming down the sights of an attached gun model.
• Biped Parts Finder - Editor script for search simplification of parts of a biped body.
• Click To Move - Moves an object towards the mouse position when the Left Mouse Button is clicked
• ClickCharacterController - Uses Locomotion to move a character to the point the Left Mouse button is clicked
• DoubleJumpController - A hack for the 2d gameplay tutorial character controller script, it allows the character to make a second jump when jumping, or make a little jump when falling.
• Finite State Machine - A simple Finite State Machine framework to control NPCs.
• Force2D - Constrain a GameObject to move in two dimensions.
• FPSWalkerEnhanced - Adds features to standard FPSWalker, such as sliding down slopes, falling damage, and walk/run modes
• Gesture_Recognizer - A math based gesture recognition script.
• GridMove - A controller for character movement typically seen in old-school 2D RPGs and strategy games.
• HeadLookController - A component that can be used to make a character look towards a specified point in space, smoothly turning towards it with for example the eyes, head, upper body, or whatever is specified.
• JCar - A car using wheel colliders.
• KeyCombo - A class that can be used to detect fighting-game style combos.
• LookAtMouse - Cause an object to rotate toward the cursor, along the y axis.
• Pathfinding - [Old] A pathfinding-system using raycasting to avoid obstacles
• PhysicsFPSWalker - Another physics based fps walker script.
• RigidbodyFPSWalker - An physics based FPS walker that works with rigidbodies and thus is affected by forces, joints or other rigidbodies
• SeekSteer - A class that can be used to move an object to follow a loose path of waypoints
• ShipControls - Place this script on a RigidBody for 2D spaceship controls like OverWhelmed Arena.
• SimpleTankController - A script that emulates simple tank movement.
• VariableSpeedFPSwalker - An FPS walker script having different speeds for walking forward, strafing, and back-pedalling.
• WaypointMaster - Implementation of A* algorithm, based on waypoints.

Animation Controllers

• AniMate - Script to quickly and easily create animations/tweens of almost any value and including eased, rigidbody and rotation animation.
• iTween - Focusing on the established solutions and frameworks of projects such as TweenLite, Tweener, and other tweening systems, iTween is a battle-tested solution for streamlining production in the Unity3D environment.
• MoveObject - Basic functions for when you just need to move something from point A to point B, or rotate by a given number of degrees, without anything fancy.
• Tween - An adaptation of the Tweener class of FLASH for unity.
• AnimationStepSync - Repositions object after animation ends - useful for positioning via animations.
