Scrolling text

The Weather Observation Name can be a long string, that doesn't fit into the 75% of the full width of a data field I allow for it, using a Tiny font size. I don't want to go any smaller or it is pretty much unreadable.

Is there a clever way to smoothly scroll a text screen within a fixed "mask" N pixels wide?

Altnerattuely I could parse the OBS name into words and scroll it at a word boundary, displaying only the set of full words that fit into the allowable window.

I have a class TextAnimation, that is something you could build on:

// Copyright (C) 2022 by Gavriel Fleischer ([email protected])

using Toybox.Lang;

class TextAnimation {
    private var mAnimationSteps as Array;
    private var mIndex as Number;
    private var mDirection as Number;

    function initialize(animationSteps as Array) {
        if (animationSteps.size() < 2) {
            throw new Lang.InvalidOptionsException("min 2 steps required");
        }
        mAnimationSteps = animationSteps;
        reset();
    }

    function reset() as Void {
        mIndex = 0;
        mDirection = 1;
    }

    function next() {
        var item = mAnimationSteps[mIndex];
        mIndex += mDirection;
        if (mDirection < 0 && mIndex < 0) {
            mDirection = -mDirection;
            mIndex = 1;
        } else if (mDirection > 0 && mIndex >= mAnimationSteps.size()) {
            mDirection = -mDirection;
            mIndex = mAnimationSteps.size() - 2;
        }
        return item;
    }
}

The way to use it:

hidden const SEARCH_ANIMATION = new TextAnimation(["+--", "-+-", "--+"]);

str = SEARCH_ANIMATION.next();
// or if needed then:
SEARCH_ANIMATION.reset();

VERY COOL! Thanks! I'll give that a try.
