Code Examples for Solar2D & Unity

Solar2D

This Solar2D snippet displays an animated sprite, useful for adding characters or visual elements to your app or game. Some assets – like ‘img_sprite.png’ and ‘spriteData’ – are required (not shown below) for the code to run properly.

-- Array to store sprite properties
local spriteData =
{
    { name="running", start=1, count=5, time=200 },
}

--  Image sheet to use with sprite
local img_sprite = graphics.newImageSheet("img_sprite.png", spriteData)
  
-- Create sprite
local sprite = display.newSprite( img_sprite, spriteData )

-- Position sprite
sprite.x = display.contentCenterX
sprite.y = display.contentCenterY

-- Play sprite
sprite:setSequence("running")
sprite:play()

Unity

This Unity code creates a sphere which moves on the roll of a dice. The script requires the addition of the ‘UnityEngine’ library for function optimization.

using System.Collections;
using UnityEngine;

public class RandomSphere : MonoBehaviour
{
    public float speed = 1f;
    private Vector3 target;

    void Start()
    {
        target = GetRandomTarget();
    }

    void FixedUpdate()
    {
        float step = speed * Time.deltaTime;
        transform.position = Vector3.MoveTowards(transform.position, target, step);

        if (Vector3.Distance(transform.position, target) < 0.001f)
        {
            target = GetRandomTarget();
        }
    }

    Vector3 GetRandomTarget()
    {
        return new Vector3(Random.Range(-10, 10), Random.Range(-10, 10), Random.Range(-10, 10));
    }
}

Unity or Solar2D: The Informed Choice

Seedbeds of innovation, Solar2D, and Unity have decisively redefined cross-platform mobile app development. Understanding nuances of each could be pivotal to your breakthrough, but which is the right fit?

The Mobile Game Dev Novice

For those dipping toes into mobile game development, the accessible, Lua-based scripting of Solar2D offers an easy entry point. The Solar2D Simulator facilitates live testing, while its vibrant community fosters collaborative learning.
