|---|---|
| animationId | Property = animationId {int} Loop id returned by Animation.start |
| begin | APIProperty = begin {Object} Values to start the animation with |
| callbacks | APIProperty = callbacks {Object} An object with start, eachStep and done properties whose values are functions to be call during the animation. They are passed the current computed value as argument. |
| duration | APIProperty = duration {int} duration of the tween (number of steps) |
| easing | APIProperty: easing
{ |
| finish | APIProperty = finish {Object} Values to finish the animation with |
| minFrameRate | APIProperty = minFrameRate {Number} The minimum framerate for animations in frames per second. After each step, the time spent in the animation is compared to the calculated time at this frame rate. If the animation runs longer than the calculated time, the next step is skipped. Default is 30. |
| playing | Property = playing {Boolean} Tells if the easing is currently playing |
| startTime | Property = startTime {Number} The timestamp of the first execution step. Used for skipping frames |
| time | Property = time {int} Step counter |
