An example of how to create rough APL sprite animations using Pagers and sequential page commands. Your mileage may vary on smoothness of transition based on other commands being executed.

spriteAnimations.js

...

let spriteCommands = [];
for (...) {
    
    ...
    
    spriteCommands.push({
        "type": "SetPage",
        "componentId": "b",
        "position": "relative",
        "value": spriteNumber,
        "delay": frameTime
    });
}

...

handlerInput.responseBuilder.addDirective({
    type: 'Alexa.Presentation.APL.ExecuteCommands',
    token: 'map',
    commands: [{
        "type": "Sequential",
        "commands": spriteCommands
    }]
});

spritePager.json

{
    "type": "Pager",
    "id": "b",
    "data": [...],
    "width": "15vh",
    "height": "100vh",
    "scrollDirection": "vertical",
    "items": [{
        "type": "Container",
        "height": "100vh",
        "width": "100vw",
        "bind": [{
            "name": "parentIndex",
            "value": "${index}"
        }],
        "items": [{
            "type": "Image",
            "backgroundColor": "#ff0000",
            "source":"${data}",
            "height": "15vh",
            "width": "15vh"
        }]
    }]
}
