Unreal Engine vs Heaps: Pricing

While Unreal Engine operates with a royalty model charging 5{66f7997927a862c9f57ec7dffc6a2fe6d405caee7001dff533b976d48fe118b1} of revenues over $1 million, Heaps provides no explicit pricing details and appears to be a free resource for developers.

Unreal Engine

The Unreal Engine employs a unique pricing model that charges developers for utilizing their engine, based on the revenue they generate. Epic Games, the software’s proprietor, collects a 5{66f7997927a862c9f57ec7dffc6a2fe6d405caee7001dff533b976d48fe118b1} royalty fee off gross revenues above $1 million that any project makes. This fee is dismissed for games published directly on the Epic Games Store. Additionally, Unreal Engine is offered free for educational institutions such as schools and universities.

Heaps

Heaps does not provide any explicit pricing information, suggesting that it is a free tool for developers to use. Being more of a library than a complete game engine, its adoption and usage costs are presumably absorbed by the development process. However, it’s crucial for prospective users to undertake their research or consultation for precise details on any possible hidden costs.

Code Examples for Unreal Engine & Heaps

Unreal Engine

This Unreal Engine example will implement a day-night cycle system. It is recommended that you are familiar with Blueprints Visual Scripting and Actor class, to comprehend this code effectively.

    public class CustomSkyDome {
    UPROPERTY(EditAnywhere, float);
    UCurveFloat* SunHeightCurve;
    
    UPROPERTY(EditAnywhere, float);
    float dayLength;
    
    UFUNCTION(BlueprintImplementableEvent, meta = (DisplayName = "Day Ended"));
    void DayEnded();
    
    UFUNCTION(BlueprintImplementableEvent, meta = (DisplayName = "Night Ended"));
    void NightEnded();
    
    UFUNCTION(BlueprintCallable, Category = "Sky")
    void UpdateSun(float time);
    
    UFUNCTION(BlueprintPure, Category = "Sky")
    float GetSunHeight();
    }

Heaps

This Heaps example will create a simple sprite animation. You should have Haxe and Heaps installed for this instance to work flawlessly.

    import h2d.Sprite;
    
    class Main extends hxd.App {
        var sprite : Sprite;
        override function init() {
            sprite = new Sprite(hxd.Res.loader.get("my_texture").toTile(), s2d);
        }
        override function update(dt:Float) {
            sprite.x += dt * 100;
            if (sprite.x > s2d.width)
                sprite.x = -sprite.width;
        }
        static function main() {
            new Main();
        }
    }

Which Delivers Your Dream Game: Unreal Engine or Heaps?

Making a choice between Unreal Engine and Heaps might seem daunting, but it all narrows down to your requirements, proficiency, and your ultimate goal. Let’s dive in.

For Hardcore Developers Who Love to Experiment

If you are a hands-on developer who loves pushing boundaries with complex systems, Unreal Engine is the runtime for your imagination. From AAA games to immersive VR experiences, its powerful suite and C++ compatibility push the limits of game development. However, remember the 5{66f7997927a862c9f57ec7dffc6a2fe6d405caee7001dff533b976d48fe118b1} royalty after USD 1 million.

For Indie Developers with a Love for Community

Preferring tight-knit development communities and indie projects? Heaps has been your secret weapon all along. The Haxe-based engine gives you access to an active community. Enjoy the power behind titles like Dead Cells and Northgard, while focusing on deep storylines and game systems.

For Cross-platform Developers Needing Flexibility

Are you a cross-platform developer who prioritizes code portability? Heaps and its Haxe DNA embraces your productivity from Flash’s ashes. Combined with potential performance optimization and stability, achieving platform-independent benefits become a reality.

As a verdict, Unreal Engine captivates with powerful functionalities and vast platform support, yet it demands a higher learning curve and a royalty fee.
