Methods

qi::Future<void> ALAnimationPlayerProxy::run(const std::string& path)

Runs an animation.

Parameters:

• path – Path to the animation. For further details, see: Animation Paths

Returns:

A future to cancel the animation.

Calling the method asynchronously allows to cancel the animation by canceling the future.

qi::Future<void> ALAnimationPlayerProxy::runTag(const std::string& tag)

There are two overloads of this function:

• ALAnimationPlayerProxy::runTag
• ALAnimationPlayerProxy::runTag for a specific package.

Runs an animation randomly chosen among all the animations with a specified tag.

Parameters:

• tag – Tag of animations. For further details, see: Tags

Returns:

A future to cancel the animation.

qi::Future<void> ALAnimationPlayerProxy::runTag(const std::string& path, const std::string& tag)

Runs an animation randomly chosen among all the animations, contained in a specified path, and with a specified tag.

Parameters:

• path – Path to look for the animations.
• tag – Tag of animations. For further details, see: Tags

Returns:

A future to cancel the animation.

void ALAnimationPlayerProxy::declarePathForTags(const std::string& path)

Allow using animations contained in the specified path as tagged animations.

Parameters:

• path – Path that contains tagged animations. If [posture] is in the path it will be replaced by all handled posture families (not only the current one).

void ALAnimationPlayerProxy::addTagForAnimations(const TagForAnimations& tagsToAnimations)

Associates tags to animations.

Parameters:

• tagsToAnimations – Map of tag to animations. (in C++ it’s std::map<std::string, std::vector<std::string> >)
