# You can configure all individual animations.
# Available settings are the same for all of them.

#
# Niri supports two animation types: easing and spring.
# You can set properties for only ONE of them.
#
# Easing has the following settings:
# - duration-ms sets the duration of the animation in milliseconds.
# - curve sets the easing curve. Currently, available curves
# are "ease-out-cubic" and "ease-out-expo".
#
# Spring animations work better with touchpad gestures, because they
# take into account the velocity of your fingers as you release the swipe.
# The parameters are less obvious and generally should be tuned
# with trial and error. Notably, you cannot directly set the duration.
# You can use this app to help visualize how the spring parameters
# change the animation: https://flathub.org/apps/app.drey.Elastic
#
# A spring animation is configured like this:
# - (leaf "spring" { damping-ratio=1.0; stiffness=1000; epsilon=0.0001; })
#
# The damping ratio goes from 0.1 to 10.0 and has the following properties:
# - below 1.0: underdamped spring, will oscillate in the end.
# - above 1.0: overdamped spring, won't oscillate.
# - 1.0: critically damped spring, comes to rest in minimum possible time
# without oscillations.
#
# However, even with damping ratio = 1.0 the spring animation may oscillate
# if "launched" with enough velocity from a touchpad swipe.
#
# Lower stiffness will result in a slower animation more prone to oscillation.
#
# Set epsilon to a lower value if the animation "jumps" in the end.
#
# The spring mass is hardcoded to 1.0 and cannot be changed. Instead, change
# stiffness proportionally. E.g. increasing mass by 2x is the same as
# decreasing stiffness by 2x.
# Animation when switching workspaces up and down,
