class CPAnimationSprite(id: String, anis: Seq[CPAnimation], x: Int, y: Int, z: Int, initAniId: String, collidable: Boolean, shaders: Seq[CPShader], tags: Seq[String]) extends CPSceneObject

A scene objet tailor-made for showing animations based on CPAnimation.

This sprite allows to implement a visual scene object that has one or more animations associated with it. These animations can be controlled either by the sprite itself or from the outside. This class provides necessary implementation for update and render methods. Make sure to call super if overriding any of these methods.

There are additional methods that allow access to and the control of the animation in the sprite:

Typically, to create a moving sprite, one would override this class and implement movement logic in overridden update method (making sure to call super), as well as overriding getX, getY and getDim methods to return current coordinates and dimension. Note that in most cases, one do need to override or change render method.

Value parameters

anis

Sequence of animation. Must have at least one animation in it.

collidable

Whether or not this sprite is collidable.

id

Optional ID of the sprite.

initAniId

ID of the initial animation to play. This animation starts to play immediately.

shaders

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

tags

Optional set of organizational or grouping tags. By default, the empty set is used.

x

Initial X-coordinate.

y

Initial Y-coordinate.

Inherited methods

override def equals(obj: Any): Boolean

Compares the receiver object (this) with the argument object (that) for equivalence.

Compares the receiver object (this) with the argument object (that) for equivalence.

Any implementation of this method should be an equivalence relation:

  • It is reflexive: for any instance x of type Any, x.equals(x) should return true.
  • It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any instances x, y, and z of type Any if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override hashCode to ensure that objects which are "equal" (o1.equals(o2) returns true) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)).

Value parameters

that

the object to compare against this object for equality.

Attributes

Returns

true if the receiver object is equivalent to the argument; false otherwise.
