Unreal Engine vs Solar2D: Pricing

While the Unreal Engine employs a royalty model, charging 5{66f7997927a862c9f57ec7dffc6a2fe6d405caee7001dff533b976d48fe118b1} for revenue exceeding USD 1 million, Solar2D operates completely free, eliminating unexpected charges and royalty costs.

Unreal Engine

The pricing model of the Unreal Engine is primarily structured around royalties. Once revenue exceeds USD 1 million, Epic Games charges a 5{66f7997927a862c9f57ec7dffc6a2fe6d405caee7001dff533b976d48fe118b1} royalty fee. However, this fee is waived for games published directly on the Epic Games Store. The Unreal Engine Marketplace also fosters exchanges between creators and consumers, with content creators receiving 88{66f7997927a862c9f57ec7dffc6a2fe6d405caee7001dff533b976d48fe118b1} of generated revenues. In a move to support education, Unreal Engine is offered free of charge to schools and universities. For all users, Unreal Engine 4 was released for free, with a royalty of 5{66f7997927a862c9f57ec7dffc6a2fe6d405caee7001dff533b976d48fe118b1} charged on products earning over $3,000 per quarter.

Solar2D

Solar2D stands in stark contrast with its completely free, open-source model. It complies with an MIT license and ensures privacy, with no hidden fees or royalties involved for developers. Users are allowed to modify and distribute under the open-source license, making it economically accessible to a larger audience. This price advantage coupled with powerful APIs and a broad range of platform support keeps it a strong competitor against rival technologies.

Code Examples for Unreal Engine & Solar2D

Unreal Engine

In this Unreal Engine code snippet, we will create a simple first person shooter mechanic. Unreal Engine relies heavily on C++ and its proprietary Unreal Engine scripting language, Blueprint. Hence, knowledge of both C++ and Blueprint are prerequisites. In terms of software requirements, the Unreal Engine version used should be 4.26 or above.

    // Add this to Character's header file

    UFUNCTION()
    void Fire();

    UPROPERTY(EditAnywhere)
    UParticleSystem* MuzzleFlash;

    // Add this to Character's .cpp file

    void AYourCharacter::Fire()
    {
        if (MuzzleFlash)
        {
            UGameplayStatics::SpawnEmitterAttached(MuzzleFlash, GetMesh(), "MuzzleFlashSocket");
        }

        FHitResult Hit;
        FVector ShotDirection;
        bool bSuccess = GunTrace(Hit, ShotDirection);

        if (bSuccess)
        {
            UGameplayStatics::ApplyPointDamage(Hit.GetActor(), Damage, ShotDirection, Hit, nullptr, this, DamageType);
        }
    }

Solar2D

This Solar2D code snippet illustrates the creation of a simple physics-based bouncing ball mechanic. Solar2D uses Lua for scripting, so a preliminary understanding of Lua is necessary. No specific version requirement is needed to execute this code successfully.

    -- Include Physics engine
    local physics = require("physics")
    physics.start()

    -- Set Gravity
    physics.setGravity( 0, 9.8)

    -- Create a simple bouncing ball
    local ball = display.newCircle( 100, 100, 20)
    ball:setFillColor( 1, 0, 0)

    -- Add physics to the ball
    physics.addBody( ball, "dynamic", { bounce = 0.8, radius = 20})

    -- Create ground
    local ground = display.newRect( display.contentWidth/2, display.contentHeight, display.contentWidth, 10)

    -- Add physics to the ground
    physics.addBody( ground, "static")
