Anim
ABSTRACT
The base functor for all animations. It is not recommended you use this functor directly
PARAMETERS
| pull& | a variable-tree, that can be used to keep track of state. By convention, pull is used for variables we want to write to throughout the animation |
| push& | a variable-tree, that can be used to keep track of state. By convention, push is used for variables we want to read from throuhgout the animation |
| sentinel(t,dt,pull&,push&) | the function that is called each frame with the current time, the changei n time, and references to the user provided pull and push variables. The function should do whatever it wants with the state, and then return 0 to indicate the animation is not finished, 1 if the animation must be finished immediately, or -1 if the animation can exit, but should continue if animations that are in parallel with it are still running |
RETURN
an animation that obeys the specified behavior. Note that the animation is not run immediately when it is created.
DECLARATION
