2.1 animation
| (require qtops/qualities/animation) | package: qtops |
The animation quality provides a thing with a list of animations the ability to execute them on a schedule. Typically, animations are triggered by scheduling them within the thing’s universe.
NOTE: things with the animation quality are assumed to exist within a universe.
procedure
(animations t) → procedure?
t : procedure? (animations) → list?
Returns a procedure which follows the second form, where the list is of the format described in set-animations!.
procedure
(set-animations! t) → procedure?
t : procedure? (set-animations! A) → void A : list?
Returns a procedure for t which accepts one argument, a list. Each item on the list is expected to take the following format:
(list symbol integer integer)
Where the symbol is a procedure that t has, that will be called when t’s animate procedure is called, the first integer is the frequency (in moments, a concept from the time quality.), and the second integer is the % chance of the procedure actually being called.
Alternatively, either or both integers can be a procedure, as long as those procedures return integers.
