Sprites are 2D Graphic objects. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development. More info See in Glossary and a Sprite Packer A facility that packs graphics from several sprite textures tightly together within a single texture known as an atlas.
Unity provides a Sprite Packer utility to automate the process of generating atlases from the individual sprite textures. More info See in Glossary. See Importing and Setting up Sprites below for information on setting up assets as Sprites in your Unity project.
Use the Sprite Creator to create placeholder sprites in your project, so you can carry on with development without having to source or wait for graphics. The Sprite Editor lets you extract sprite graphics from a larger image and edit a number of component images within a single texture in your image editor. You could use this, for example, to keep the arms, legs and body of a character as separate elements within one image. Use it to display images as Sprites for use in both 2D and 3D scenes A Scene contains the environments and menus of your game.
Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. Use Sprite Packer to optimize the use and performance of video memory by your project. Sprites are a type of Asset Any media or data that can be used in your game or Project. An Asset may come from a file created outside of Unity, such as a 3D model, an audio file or an image. More info See in Glossary in Unity projects.
You can see them, ready to use, via the Project In Unity, you use a Project to design and develop a game. A Project stores all of the files that are related to a game, such as the Asset and Scene files.
2D Inverse Kinematics (IK)
More info See in Glossary view. See Importing for more details on this and important information about organising your Assets folder. If your project mode is set to 2D, the image you import is automatically set as a Sprite. For details on setting your project mode to 2D, see 2D or 3D Projects. Textures are often applied to the surface of a mesh to give it visual detail. Renderers in Unity are sorted by several criteria, such as their Layer order or their distance from the Camera.This package contains tools which help to determine the translated positions of a group of transforms given a desired target position using inverse kinematics IK.
This will make it easier for you to pose characters for animation or aid you in manipulating characters in real-time. This component controls and drives all of the IK solvers for this package. An IK solver without a IK manager will not work. These are the default solvers that come with the package. Choose the right solver for your particular IK problem. This is an iterative solver which generates an approximate solution for the IKs and slowly converges to a better solution the more times the algorithm is run.
Due to this an exact solution may not be reached and this solver will run to a predefined tolerance or number of runs. This is also an iterative solver which generates an approximate solution for the IKs and slowly converges to a better solution the more times the algorithm is run. You can add your own solver by extending from the class Solver2D.
Your extended class will then show up as a new solver under the solver menu in the IKManager2D component. This is the base class for all IK solvers in this package. IKManager2D will detect all classes extending this and accept it as a solver it can control. Implement or override the following methods to create your own IK solver:.
This is the class which is used to store the transforms involved in an IK chain. When a chain is set up with a target and a transform count, the solver's Initialize will populate the chain with the right transforms if valid. Use this if you do not want to use the name of the class of the Solver2D. Workflow Setup your hierarchy of Transforms for IK. Create a GameObject for IK.
Setup your individual IK solvers. The parameters specific to each solver are listed below. If desired, setup effectors for each individual IK solver. This will be useful for having IK targets in runtime. Pose your hierarchy of Transforms using effectors or pose gizmos in the SceneView. Properties: Weight This is the master weight which affects all solvers controlled by the manager. This weight will be applied to each solver's weight and will be used to blend between the results of the IK solver positions and the original positions of the Transforms affected.
Solvers This is a list of all solvers which are controlled by this IK manager. Arrange all IK solvers in this to run them in order of priority.Create and define the bones for your Sprites and their hierarchy in the Bone Editor. When building bones to for the animation of a Sprite, the first bone created is the Root bone for the bone hierarchy of that Sprite.
In Create Chain Bone mode, newly created bones are automatically parented to the previous bone in the hierarchy. In Free Bone modenew bones are parented to the currently selected bone regardless of their position in the hierarchy. If no bone is currently selected, the new bone is automatically parented to the Root bone by default.
If no tools are selected, the editor is in Transform mode, and a bone's Pivot, Body and Tail can be selected and transformed. Select the Create Chain Bone tool and click anywhere in the Sprite to start creating a chain of bones. Press Esc to deselect the tool. In this mode, it is easy to control entire chains of bones and their lengths and positions, as each bone is connected to each other together in a continuous chain.
The Create Free Bone tool is used to create bones that do not form a continuous chain of bones. The Free Move tool is used to detach a bone from a chain and move it independently. It will no longer be connected to the chain but will still be parented to it original parent bone.
The Parent Tool is used to change the parent of a child bone. First select the child bone, then click Parent Tool then click on the new target parent. The Split Tool splits a selected bone. First select a bone, then select the Split Tool to split the selected bone into two. This editor is where Sprite geometry is generated, and vertex weights are then assigned to the bones to deform the geometry.
Create mesh geometry created manually in the Create Vertex or Create Edge modes. From the top menu, select Create Vertex and click anywhere within the Sprite to create vertices.
Then select Create Edge and click on vertices to connect them together to form new edges. Select Split Edge and then click on an edge to split it into multiple pieces. You can create vertices and new edges directly in Selection mode as well.
While in Selection modedouble-click anywhere on the Sprite to create vertices. Hold Shift to connect a selected vertex to another to create an edge. Select the Weight modeand then select a Sprite to begin applying skin weights. Click Auto to automatically generate weights based on the Sprite's bones, which can be edited manually later.
There are two tools to edit the Weights - the Slider and the Brush. The Slider allows direct manipulation of the values of selected vertices; while the Brush tool allows you to 'paint' skin weights directly on the mesh. The weights for selected vertices can be viewed and further adjusted with the vertex inspector located at the bottom-left of the Editor window. You can preview the effect of the painted weights within the Sprite Editor. Select and hold a bone to move or rotate it. The Sprite's geometry mesh deforms according to the weights painted.
Robotic Arm with Inverse Kinematics
Releasing the bones resets them and the mesh back to their original state. The Sprite Skin component is needed for the bones to deform the Sprite mesh in the Scene.
Select and hold a bone to pivot it around its head and deform the Sprite's mesh directly in the Scene to begin animating it.
Moving selected bones together deforms the mesh across all of them. Bones that are not directly chained together can also be selected and moved together.I have run across the problem that mecanim IK gets messed up if i scale the objects. Does anybody know a work around for this problem?

In this post we show how these integrated 2D tools can help you create high-end visuals with Unity.
Highly skilled teams have been making gorgeous 2D games with Unity for years, but we wanted to enable everyone, from individual artists to large teams, to have even more 2D tools available to create great-looking games.
And many of them will be production-ready as part of Unity We created Lost Crypt using the complete suite of 2D tools. This lively scene features animation, light effects, organic terrain, shaders, and post-processing, all made natively in 2D.
It shows how teams and projects of all sizes, targeting any platform, can now get more engaging and beautiful results faster. Lost Crypt should run well on any desktop computer and we have also implemented on-screen controls with the new Input System in case you want to run it on an iOS or Android device. In our tests it ran at 30 fps on common devices like an iPhone 6S.
Download from Asset Store. The project includes all the 2D packages you need. It will then overwrite the project settings, changing rendering settings to the 2D Renderer within the Universal Render Pipeline. Once you import it, you will see the Main Scene. When you click Play you should be able to play normally using the keyboard arrows and spacebar to jump.
Original concept art. We made the project in collaboration with B2tGame. Open the Sara. If you open the file with Photoshop, you will see how we kept the different parts and layer names intact. The PSD Importer allows us to use Photoshop files directly in Unity without having to export separated Sprites and reassemble them later.
Compared to the usual Sprite-Default material, this one allows Sprites to react to 2D lighting conditions. We imported the character Normal maps in the Sprite Editor, using the Secondary Textures drop-down menu. You can add Normal and Mask maps to 2D animated characters, regular Sprites, tilemaps, and Sprite shapes. The Normal map used for the character indicates which areas of the Sprite should reflect more or less light.Search Unity.
