Recently I’ve made an interpolation utility that works well for scale and position animation . Here it is:
github.com/plafone/EasingUtils
The code is well documented, but contact me if you have issues using it.
Looks pretty cool!
Since panda already has builtin intervals, it could be handy to have those transition modes in the default intervals, too, since they only support basic transitions like “easeIn”, “easeOut” and “easeInOut”.
