Unity即将到来的2D工具

孙广东 2015.7.5
看了一下对功能介绍的视频，确实功能强大。
但是需要***在youtube上观看，所以就下载下来了，可以浏览一下：

Release Notes

TileMap	Description	Issues #	Videos/Demos
Tile Animation	Tiles can be animated with a simple loop of sprites. Animations can be set by * Location - The tile at (x, y) will play the animation * Tile Type - All tiles painted with the same sprite will play the animation The priority order for rendering tile map animations: 1. Location 2. Tile Type 3. Tile (Renders the original sprite painted if there is no animation)	#31
Brush Flip	Allows you to flip sprites across the X and Y axis and paint the sprites onto the tile map. The following keys have been bound: * x: Flips sprites horizontally * y: Flips sprites vertically	#26
Undo	Undo all changes to the tile map
Tile Transform API	Position, Rotation, Scale functions have been added to set the transform for tiles in the tile map
SmartSprite	Description	Issues #	Videos/Demos
Curved Edges	Edges can be tessellated as spline with point rotation support	#37	Video
Delete Points	Delete points directly from scene view by selecting it and pressing Delete on Windows. (fn+Delete on Mac).
Physics2D	Description	Issues #	Videos/Demos
Relative Joint	Keeps two Rigidbody2D at their relative orientation using configurable maximum linear/angular forces (Uses Box2Ds b2MotorJoint)		Video
Fixed Joint	Rigidly connects two Rigidbody2D together at their anchor points (Uses Box2Ds b2WeldJoint)		Video
Target Joint	The joint attempts to move a Rigidbody2D to a specific target position (Uses Box2Ds b2MouseJoint)		Video
Friction Joint	Applies both force and torque to reduce both the linear and angular velocities to zero (Uses Box2Ds b2FrictionJoint)		Video
Buoyancy Effector	Applies forces to simulate buoyancy, fluid-flow and fluid drag.		Video
Use Collider Mass	New Rigidbody2D.useColliderMass property calculates the mass of the Rigidbody2D from the total mass of all colliders. Each collider mass is its Density x Area.		Video
All Joints	Breakable joints using BreakForce/BreakTorque. New properties to expose current reaction-force/torque that use the current fixed time-ste		Video
All Joints	Auto-Configure Connected-Anchor		Video
Distance Joint & Spring Joint	Auto-configure Distance		Video
Slider Joint	Auto-Configure Angle		Video
Skew	Description	Issues #	Videos/Demos
Skew with RectTransform	2D Images now supports skewing via RectTransform	#47
Masking	Description	Issues #	Videos/Demos
Workflow improvements	* Masks can affect multiple layers * Masks will affect only the layers they are selected for * Masks will automatically be rendered at the correct order based on the layers they are affecting * Masks and Mask-ables have a new editor icon that will help in visualising the entire setup	#39
Under the hood	* Moved all masking code to new component * Dedicated inspector for masking component
9-Slice	Description	Issues #	Videos/Demos
Collider Support	2D colliders do not auto resize when SpriteRenderer is in 9 slice mode. User needs to attach the ‘Tile Collider’ component for 2D colliders to resize in 9 slice mode

New Demos

Tile Map
Pixel Perfect Demo

Known Issues

No component icons for RelativeJoint2D, FixedJoint2D, TargetJoint2D, FrictionJoint2D or BuoyancyEffector2D
Maskable sprites does not work within a prefab.
SmartSprite splines may 'loop' around itself under various circumstances which creates poorly tessellated edges.
SmartSprite's edge handle is not on the line if the edge is curved
SmartSprite's polygon collider may not match curved edges perfect
