Fonts can be created or imported for use in either the GUI Text or the Text Mesh ComponentsA functional part of a GameObject. A GameObject can contain any number of components. Unity has many built-in components, and you can create your own by writing scripts that inherit from MonoBehaviour. More info
See in Glossary.
To add a font to your project you need to place the font file in your Assets folder. Unity will then automatically import it. Supported Font formats are TrueType Fonts (.ttf files) and OpenType Fonts (.otf files).
To change the Size of the font, highlight it in the Project ViewA view that shows the contents of your Assets folder (Project tab) More info
See in Glossary and you have a number of options in the Import Settings in the InspectorA Unity window that displays information about the currently selected GameObject, Asset or Project Settings, alowing you to inspect and edit the values. More info
See in Glossary.
|Font Size||The size of the font, based on the sizes set in any word processor.|
|Rendering modeA Standard Shader Material parameter that allows you to choose whether the object uses transparency, and if so, which type of blending mode to use. More info
See in Glossary
|The font renderingThe process of drawing graphics to the screen (or to a render texture). By default, the main camera in Unity renders its view to the screen. More info
See in Glossary mode, which tells Unity how to apply smoothing to the glyphs.
|Character||The character set of the font to import into the font texture|
|Setting this mode to Dynamic causes Unity to embed the font data itself and render font glyphs at runtime (see below).|
Import Settings specific to dynamic fonts
|Include Font Data||This setting controls the packaging of the font when used with Dynamic font property. When selected the TTF is included in the output of the build. When not selected it is assumed that the end user will have the font already installed on their machine. Note that fonts are subject to copyright and you should only include fonts that you have licensed or created for yourself.|
|Font Names||A list of fallback fonts to use when fonts or characters are not available (see below).|
After you import the font, you can expand the font in Project View to see that it has auto-generated some assets. Two assets are created during import: “font material” and “font texture”. Unlike many applications you might be familiar with, fonts in Unity are converted into textures, and the glyphs that you display are rendered using textured quadsA primitive object that resembles a plane but its edges are only one unit long, it uses only 4 vertices, and the surface is oriented in the XY plane of the local coordinate space. More info
See in Glossary. Adjusting the font size effectively changes how many pixelsThe smallest unit in a computer image. Pixel size depends on your screen resolution. Pixel lighting is calculated at every screen pixel. More info
See in Glossary are used for each glyph in this generated texture. Text MeshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info
See in Glossary assets are 3d geometry textured with these auto-generated font textures. You will want to vary the size of the font to make these assets look crisp.
When you set the Characters drop-down in the Import Settings to Dynamic, Unity will not pre-generate a texture with all font characters. Instead, it will use the FreeType font rendering engine to create the texture on the fly. This has the advantage that it can save in download size and texture memory, especially when you are using a font which is commonly included in user systems, so you don’t have to include the font data, or when you need to support asian languages or large font sizes (which would make the font textures very large using normal font textures).
When Unity tries to render text with a dynamic font, but it cannot find the font (because Include Font Data was not selected, and the font is not installed on the user machine), or the font does not include the requested glyph (like when trying to render text in east Asian scripts using a latin font, or when using styled bold/italic text), then it will try each of the fonts listed in the Font Names field, to see if it can find a font matching the font name in the project (with font data included) or installed on the user machine which has the requested glyph. If none of the listed fallback fonts are present and have the requested glyph, Unity will fall back to a hard-coded global list of fallback fonts, which contains various international fonts commonly installed on the current runtime platform.
Note that some target platforms (WebGL, some consoles) do not have OS default fonts Unity can access for rendering text. For those platforms, Include Font Data will be ignored, and font data will always be included. All fonts to be used as fallbacks must be included in the project, so if you need to render international text or bold/italic versions of a font, you need to add a font file which has the required characters to the project, and set up that font in the Font Names list of other fonts which should use it as fallbacks. If the fonts are set up correctly, the fallback fonts will be listed in the Font Importer inspector, as References to other fonts in project.
The default font asset is a dynamic font which is set up to use Arial. If Unity can’t find the Arial font on your computer (for example, if you don’t have it installed), it will fall back to a font bundled with Unity called Liberation Sans.
Liberation Sans looks like Arial, but it does not include bold or italic font styles, and only has a basic Latin character set - so styled text or non-latin characters may fall back to other fonts or fail to render. It does however have a license which allows it to be included in player builds.
To create a custom font select ‘Create->custom font’ from the project window. This will add a custom font asset to your project library.
The Ascii Start Offset field is a decimal that defines the Ascii index you would like to begin your Character Rects index from. For example, if your Ascii Start Offset is set to 0 then the capital letter A will be at index 65 but if the Ascii Start Offset is set to 65 then the letter A will be at index 0. You can consult the Ascii Table here but you should bear in mind that custom font uses the decimal ascii numbering system.
Tracking can be set to modify how close each character will be to the next character on the same line and Line spacing can be set to define how close each line will be to the next.
To create a font material you will need to import your font as a texture then apply that texture to a material, then drag your font material onto the Default Material section.
The Character Rects section is where each character of your font is defined.
The Size field is for defining how many characters are in your font.
Within each Element there is an index field for the ascii index of the character. This will be an integer that represents the character in this element.
To work out the UV values you need to figure out how your characters are positioned on a scale of 0 to 1. You divide 1 by the number of characters on a dimension. For example if you have a font and the image dimensions on it are 256x128, 4 characters across, 2 down (so 64x64), then UV width will be 0.25 and UV height will be 0.5.
For UV X and Y, it’s just a matter of deciding which character you want and multiplying the width or height value times the column/row of the letter.
Vert size is based on the pixel size of the characters e.g. your characters are each 128x128, putting 128 and –128 into the Vert Width and Height will give properly proportioned letters. Vert Y must be negative.
Advance will be the desired horizontal distance from the origin of this character to the origin of the next character in pixels. It is multiplied by Tracking when calculating the actual distance.
Unity has full unicode support. Unicode text allows you to display German, French, Danish or Japanese characters that are usually not supported in an ASCII character set. You can also enter a lot of different special purpose characters like arrow signs or the option key sign, if your font supports it.
To use unicode characters, choose either Unicode or Dynamic from the Characters drop-down in the Import Settings. You can now display unicode characters with this font. If you are using a GUIText or Text MeshA Mesh component that displays a Text string More info
See in Glossary, you can enter unicode characters into the Component’s TextA non-interactive piece of text to the user. This can be used to provide captions or labels for other GUI controls or to display instructions or other text. More info
See in Glossary field in the Inspector.
You can also use unicode characters if you want to set the displayed text from scripting. The C# compiler fully supports Unicode based scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info
See in Glossary. You have to save your scripts with UTF–16 encoding. Now you can add unicode characters to a string in your script and they will display as expected in UnityGUI, a GUIText, or a Text Mesh.
Note that surrogate pairs are not supported.
There are different ways to change the color of your displayed font, depending on how the font is used.
If you are using a GUIText or a Text Mesh, you can change its color by using a custom MaterialAn asset that defines how a surface should be rendered, by including references to the Textures it uses, tiling information, Color tints and more. The available options for a Material depend on which Shader the Material is using. More info
See in Glossary for the font. In the Project View, click on Create > Material, and select and set up the newly created Material in the Inspector. Make sure you assign the texture from the font asset to the material. If you use the built-in GUI/Text Shader shader for the font material, you can choose the color in the Text Color property of the material.
If you are using UnityGUI scripting to display your font, you have much more control over the font’s color under different circumstances. To change the font’s color, you create a GUISkin from Assets > Create > GUI Skin, and define the color for the specific control state, e.g. Label > Normal > Text Color. For more details, please read the GUI Skin page.
