CPLabelSprite

class CPLabelSprite(id: String, x: Int, y: Int, z: Int, font: CPFont, text: String, fg: CPColor, bg: Option[CPColor], skin: (CPPixel, Int, Int) => CPPixel, collidable: Boolean, shaders: Seq[CPShader]) extends CPSceneObject

Scene object tailor-made for rendering text labels.

This sprite accepts text and the font along with skinning function and renders this text at the given XY-coordinates. Text of the label can change dynamically. Note that the dimension of the sprite is changing along with the change of the label's text.

Sprites

CosPlay provides number of built-in sprites. A sprite is a scene objects, visible or off-screen, that is custom designed for a particular use case. Built-in sprites provide concrete implementations for the abstract methods in the base CPSceneObject class. Most non-trivial games will use combination of the built-in sprites and their own ones. Here's the list of the built-in sprites:

Value parameters:
bg

Optional background color. Default value is None.

collidable

Whether or not this sprite provides collision shape. Default value is false.

fg

Foreground color.

font

Font to use for label.

id

Optional ID of this sprite.

shaders

Optional sequence of shaders for this sprite. Default value is an empty sequence.

skin

Skinning function. The function takes an existing pixel, its X and Y coordinate and return a new pixel. Default value is the function that returns the same pixel.

text

Label text.

x

X-coordinate of the top-left corner of the label.

y

Y-coordinate of the top-left corner of the label.

z

Z-index at which to render the label.

Example:

See CPTextInputExample class for the example of using labels and text input.

override def render(ctx: CPSceneObjectContext): Unit

Called to render this scene object. Only visible and in camera frame objects will receive this callback. This callback is called on scene object after all scene objects received update callback. Note that unlike update callbacks and shaders that are called for all scene objects on each frame, this callback is only called for scene objects that are visible and, at least partially, in camera frame.

override val getX: Int

Gets current X-coordinate of this object within dimensions of its scene. Note that returned value is allowed to be outside scene's dimension (e.g. negative value). In such cases, the clipping of the scene rendering will result in showing only portion or none of the object.
