For example, you might display an explosion by sending particles with a fire texture out at great speed from a central point. When many of these particles are created at once and set in motion, optionally with random variations, they can create a very convincing effect. A particle is a small 2D graphic representing a small portion of something that is basically fluid or gaseous, such as a smoke cloud. This type of effect is handled much better by Particle Systems. Meshes are ideal for representing solid objects but less suited for things like flames, smoke and sparkles left by a magic spell.

See the manual chapter on GUI Scripting Guide for further details about Unity’s GUI system. These graphics are clearly very different from the kind used to detail a mesh surface but they are handled using standard Unity textures nevertheless. For example, the score display and the options menu are typical examples of game GUI. More info See in Glossary but are there to allow the player to make choices and see information. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. Think of each unique Scene file as a unique level. GUIĪ game’s graphic user interface (GUI) consists of graphics that are not used directly in the game scene A Scene contains the environments and menus of your game. See the manual page about the Sprite Editor for more information. Special techniques are available to allow these sets of images to be designed and rendered efficiently. Sprite from a 3D viewpointĪn object in a 2D game may require a set of related graphic images to represent animation frames or different states of a character. More info See in Glossary are implemented using textures applied to flat meshes that approximate the objects’ shapes. 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. In 2D games, the Sprites A 2D graphic objects. For more information about importing textures, please read the Texture Component page. More info See in Glossary or Normalmap for different types of applications in the game. The six squares form the faces of an imaginary cube that surrounds an object each face represents the view along the directions of the world axes (up, down, left, right, forward and back). Using the Import Settings, it can also be converted to a Cubemap A collection of six square textures that can represent the reflections in an environment or the skybox drawn behind your geometry. More info See in Glossary, or GUI Texture. The material can then be applied to a mesh, Particle System A component that simulates fluid entities such as liquids, clouds and flames by generating and animating large numbers of small 2D images in the scene. Once your texture has been imported, you should assign it to a Material. 32x32, 64圆4, 128x128, 256x256, etc.) Simply placing them in your project’s Assets folder is sufficient, and they will appear in the Project View. You should make your textures in dimensions that are to the power of two (e.g. They can also make use of two or more textures at a time, combining them for even greater flexibility. Shaders can implement lighting and colouring effects to simulate shiny or bumpy surfaces among many other things. More info See in Glossary to render a texture on the mesh surface. Materials use specialised graphics programs called Shaders A program that runs on the GPU. Textures are applied to objects using Materials An asset that defines how a surface should be rendered. Unity can import textures from most common image file formats.
#Unity texture packing software#
The positioning of the texture is done with the 3D modelling software that is used to create the mesh. You can think of a texture image as though it were printed on a rubber sheet that is stretched and pinned onto the mesh at appropriate positions. A texture is just a standard bitmap image that is applied over the mesh surface. Textures are often applied to the surface of a mesh to give it visual detail. More info See in Glossary geometry of an object only gives a rough approximation of the shape while most of the fine detail is supplied by Textures An image used when rendering a GameObject, Sprite, or UI element. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. Unity supports triangulated or Quadrangulated polygon meshes. Meshes make up a large part of your 3D worlds. Normally, the mesh The main graphics primitive of Unity.
