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

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. Default value is zero.
y: Initial Y-coordinate. Default value is zero.
z: Initial Z-index. Default value is zero.

Concrete methods

Changes the currently playing animation.

Value parameters

finish: Whether or not to finish the current animation before changing to the given one. If false current animation will stop immediately and the next frame will play the new animation. The default value is true.
id: ID of the new animation to change to. Note that this animation should have been passed into the constructor of this sprite.
reset: Whether or not to reset() the animation before it is played. Default value is true.

Checks whether this sprite contains given animation.

Value parameters

id: ID of the animation to check.

Attributes

Gets current dimension (width and height) of this object.

Attributes

Definition Classes: CPSceneObject
Source: CPAnimationSprite.scala

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 and monitor callbacks. Note that unlike update and monitor 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. The order in which scene objects are called is undefined.

Note that generally this callback should not modify scene object state (which should be done in either update or monitor callbacks.

Default implementation is no-op.

Resets current animation by calling its CPAnimation.reset method.

Attributes

Rewinds this sprite by changing to initial animation.

Value parameters

finish: Whether or not to finish the current animation before changing to the initial one. If false current animation will stop immediately and the next frame will play the initial animation. The default value is true.
reset: Whether or not to reset the initial animation. Default value is true.

Attributes

Sets or removes the callback on key frame change.

Value parameters

f: Key frame change callback function that takes CPAnimation and CPSceneObjectContext as its parameters. Use None to remove previously set callback.
id: ID of animation.

Attributes

Source: CPAnimationSprite.scala

Splices in given animation. Current animation will be stopped, put on hold and the spliced in animation will play. After it is finished the algorithm will revert back to the stored animation.

Value parameters

finish: Whether or not to finish the current animation before the spliced in one starts. If false current animation will stop immediately and the next frame will play the spliced in animation. The default value is true.
id: ID of the animation to splice in. Note that this animation should have been passed into the constructor of this sprite.
reset: Whether or not to reset() spliced in animation before it is played. Default value is true.

Attributes

Source: CPAnimationSprite.scala

Called to update the internal state of this scene object. This callback is called each frame on every object in the scene and it is called before any render callback. Note that all scene object will receive this callback before first render callback. The order in which scene objects are called is undefined.

Default implementation is no-op. No rendering should be done in this callback.

Inherited methods

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.

Called after all scene objects have been updated but before any of them were rendered. It allows, for example, to rearrange UI sprites on the screen after all of them had a chance to update their dimensions but before they are actually rendered on the screen. Essentially, it provides for "post-update, pre-render" notification. The order in which scene objects are called is undefined.

Note that in most cases one should not override this callback. It is only meant for the use cases when one needs to be notified when all scene objects to be updated but before any of them are rendered. Default implementation is no-op. No rendering should be done in this callback.

Default implementation is no-op.

Value parameters

ctx: Frame context. This context provides bulk of functionality that a scene object can do in a game, e.g. interact with other scene objects, check collisions, read input events and manage input focus, add or remove scene objects, add new and switch between scenes, etc.
