[FEATURE REQUEST] Getting interpolation type by String

Issue details

Requesting for feature addition to get interpolation instance by interpolation name.

Sometimes I’d like to be able to get an interpolation type from, for example, a text file. The Interpolation class doesn’t feature a method to get an instance of Interpolation via String input. Current workaround would be something like

private Interpolation getInterpolationByName(String name) {
    try {

        Field field = Interpolation.class.getField(name);
        return (Interpolation) field.get(Interpolation.class);

    } catch (NoSuchFieldException | IllegalAccessException ex) {
        ex.printStackTrace();
        return Interpolation.linear;
    }
}

This is a feature request for a static function in the Interpolation class, that returns the appropriate instance of a built in interpolation type.

Version of LibGDX and/or relevant dependencies

I’d suggest to use a map, populate it with the interpolations you need (using reflection or anything else). IMO this is application level code, it doesn’t need to be in libgdx.

You can grab this for now. Might be handy to have in core also. https://github.com/rockbite/talos/blob/bd668638f1ed197c6c1fa00fb7c37e0d7241aed4/runtimes/talos-libgdx/src/com/rockbite/tools/talos/runtime/utils/InterpolationMappings.java
