In Cocos Creator there're three types of font assets supported: System font, Dynamic font and Bitmap font.
System font is not include in the project, it's a special asset type that only tells the platform the game is running to provide the default font from operation system (such as Windows, Mac, Android, iOS...). By default all new Labels are using system font, you can make sure it's used by checking Use System Font property from Label Component.
Import Font Asset
Currently Cocos Creator only supports TTF format for dynamic font. Just drag font file (with
.ttf extension) into Assets panel, the font asset will be imported.
Bitmap font asset has two parts:
.fnt font file and a
.png image file. You can think of
.png is a image map and
.fnt is the index to each character in the map. This file combo can be generated with specific tools, please read Bitmap font tool.
When importing Bitmap font, please make sure
.png files are dragged together into Assets panel, and they should be put into the same folder.
Imported Bitmap font asset should looks like this in Assets:
Note: to make asset loading more effective, we recommend that you create a specific folder for all your Bitmap font assets.
Using Font Asset
Font assets need Label components to render, here's how:
Create Node with Label
In Node Tree click the top left + (Create Node) button and select Create Renderer Nodes -> Node With Label, this will create a node with Label component attached in the scene.
You can also create from main menu Node -> Create Renderer Nodes -> Node With Label.
Assign Font Asset
If you create Label from menu, the label will use system font by default, you can drag your font asset from Assets panel to the
Font property field of Label component.
This will make Label renders using the font asset we just assign. You can switch the font assets any time according to the project needs. It's recommend to use system font at the prototype phase and then replace them with better looking font assets when the UI interface is more solid.
When switching font assets the other properties in Label component will stay the same. You can also check
Use System Font property any time to go back to using system font for your Label.
Create Label by Dragging Font Assets
Another shortcut method to create font asset is to drag TTF or Bitmap font asset from Assets panel to Node Tree or Scene panel. The selected font asset will be automatically assigned to the
Font property of Label component.
Bitmap font bash renderig
If the texture used by the bitmap font and the other Sprite are the same, and the bitmap font and the Sprite do not have a render object that is inserted with another texture, the bitmap font can merge the rendering batches with the Sprite. When placing a bitmap font resource, place the
.fnt file, the
.png file, and the texture file used by the Sprite in a folder, and then reference the Auto Atlas Asset to put the texture of the bitmap font and the texure used by the Sprite Into an atlas, the bitmap font bash rendering can be active in the native and WebGL environment automatically.
