Abstract view do draw sprites

Concrete views are specific for each back-end. View can also be used to implements camera and other fun things.

Introduced properties

abstract fun draw_sprite(s: Sprite)

scene2d :: View :: draw_sprite

Draw a specific sprite on the view

Redefined properties

redef type SELF: View

scene2d $ View :: SELF

Type of this instance, automatically specialized in every class

All properties

fun !=(other: nullable Object): Bool

core :: Object :: !=

fun ==(other: nullable Object): Bool

core :: Object :: ==

Have self and other the same value?

intern fun output_class_name

core :: Object :: output_class_name

Display class name on stdout (debug only).
fun serialization_hash: Int

core :: Object :: serialization_hash

Hash value use for serialization
intern fun sys: Sys

core :: Object :: sys

# View can also be used to implements camera and other fun things.
interface View
	# Draw a specific sprite on the view
	#
	# This method must be implemented for each specific view.
	# A traditional way of implementation is to use a double-dispatch mechanism
	#
