set_epsilon

Sets the precision of the spring.

The level of precision used to determine when the animation has come to a rest, that is, when the amplitude of the oscillations becomes smaller than this value.

If the epsilon value is too small, the animation will take a long time to stop after the animated value has stopped visibly changing.

If the epsilon value is too large, the animation will end prematurely.

The default value is 0.001.

Parameters:

this	a spring animation
epsilon	the new value
