Code Examples for Solar2D & Defold

Solar2D

This code snippet illustrates creating a basic Starfield parallax in Solar2D. Using a system timer, it generates a dynamic, visually appealing effect that can be incorporated into a multitude of games.

-- Starfield Generator
local stars = {}
for i=1, 50 do
    stars[i] = display.newCircle( math.random(display.contentWidth), math.random(display.contentHeight), math.random(1, 3) )
    stars[i].speed = math.random(50, 200)/100
end

local function moveStars(event)
    for i=1,#stars do
        stars[i].y = stars[i].y + stars[i].speed
        if (stars[i].y > display.contentHeight) then 
            stars[i]:translate( 0, -display.contentHeight )
            stars[i].x = math.random(display.contentWidth)
        end
    end
end

Runtime:addEventListener( "enterFrame", moveStars )

Defold

This Defold code snippet demonstrates character movement control. It allows you to integrate keyboard controls into a 2D game scenario, facilitating multi-directional movement for game characters.

-- Character Movement Controls
local function character_movement()
    if go.input.is_pressed('up') then
        go.set(".", "position.y", go.get(".", "position.y") + speed)
    elseif go.input.is_pressed('down') then
        go.set(".", "position.y", go.get(".", "position.y") - speed)
    elseif go.input.is_pressed('left') then
        go.set(".", "position.x", go.get(".", "position.x") - speed)
    elseif go.input.is_pressed('right') then
        go.set(".", "position.x", go.get(".", "position.x") + speed)
    end
end

local function init()
    input.set(mapping) -- Assuming "mapping" is previously defined based on user preferences/key mapping
end

local function update()
    character_movement()
end

These examples represent more advanced use scenarios, and may require additional setup and understanding of Solar2D and Defold’s input handling mechanics to work effectively.

Which is Mightier: Solar2D or Defold?

After unearthing a motherlode of features, let’s dissect them for key audiences and serve the verdict on Solar2D versus Defold.

The Newcomer Developer

Breaking the barrier of gaps and lapses is Solar2D. Live Builds, immediate app updates over local networks, and an instant-update Simulator all allow beginners to iterate quickly and fearlessly. The open-source MIT license and free usage removes financial deterrents. Single code base and Lua scripting adds to cost and time efficiency, while ease of learning trumps competitors.

The Game Jam Squadron

Defold steals the limelight for rapid game development challenges. Offering slick features such as a built-in code editor, debugger, profiler, scene, and UI editors, it is a veritable combat knife. Ease of use, coupled with rich technical documentation, facilitates crafting bite-sized games in crunch times.

The Advanced Creator

For seasoned veterans aiming for the stars and beyond, both Solar2D and Defold promise powerful results. However, if the battlefield tilts between mobile applications, Solar2D with its vast range of platforms win the day.

Whether you’re the new kid on the block or a seasoned campaigner, your best friend in arms becomes evident. Solar2D trumps for newcomers, while for game jam enthusiasts, Defold emerges victorious. If you’re coding mobile apps, Solar2D should be your weapon of choice.
