Cocos Game Engine vs. Unity: Difference, Pros, and Cons

Cocos game engine specializes in 2D mobile game development, whereas Unity is ideal for cross-platform 2D and 3D games. Game engines overall provide tools and spaces needed to create, run and export video games, but differ in specialization regarding the tools and features. The community size and target users vary depending on engine toolsets as well. Cocos is lightweight with a more coding-based workflow, so it’s ideal for experienced mobile devs. Unity has scripting tools and supports visual scripting, making it usable by both beginners and experienced devs that want to go into VR/AR games.

Keep reading for detailed explanations of which engine is better for game development (in general and for 2D specifically), which is ideal for beginners, their relative system requirements, and the pros and cons of using each engine.

Which is better for game development: Cocos Engine vs. Unity?

Cocos engine, also known as Cocos Creator, is better for lightweight, 2D mobile game development, while Unity is better for complex, 3D and cross-platform game development. Cocos is open-source with a varied toolset that gives experienced programmers finer control but the tools aren’t as advanced as Unity’s. The table below goes into aspects to consider when choosing between Cocos and Unity, including their performance and prototyping use.

Performance refers to the engines’ runtime, resource use and scalability. Cocos is ideal for 2D mobile games like Clash of Kings, producing small builds that allow it to run even on low-end devices. Unity is optimized for 3D and complex projects so it needs more advanced hardware, but heavier builds require this anyway.

Unity comes with efficient editing tools, and the drag-and-drop interface reduces the need to code, so it’s easy to put prototypes together visually and experiment with ideas. Cocos has fewer visual tools and its logic needs to be written via scripting languages, but since it’s lightweight, it’s ideal for small projects and fine-tuning coding skills.

Unity has a large community that contributes to tutorials, plugins and to Asset marketplace, which is a useful resource when starting out. Users are able to download full scene packs for specific genres without starting from scratch. Cocos’s community is smaller but focused on tweaking the engine source code since it’s open-source. The Cocos community is strongest in mobile and Asian-based markets. Using both Cocos and Unity to take advantage of each set of assets and features is possible but needs to be done with Cocos2d-x. Cocos2d is the predecessor to Cocos Creator, and is an open-source framework rather than an engine.

Cocos2d is less complex to integrate Unity in at the code level since it’s more modular than Cocos Creator. Devs are able to do so via Unity Ads SDK wrappers (for monetization) or port rendering modules. Scripts still need to be rewritten when devs want to export their code since Cocos and Unity use different scripting languages. To just export Unity assets or scenes into Cocos Creator, tools like Unity2Cocos are available.

Which is better for 2D games: Cocos Engine or Unity?

Cocos engine is better for 2D games, specifically mobile games, as the primary focus is on 2D game development, so it’s not slowed down by additional 3D features. Unity comes with tools for both 2D and 3D development, so even though the toolset is useful, the engine strains both hardware and budget.

Cocos is optimized for mobile so the runtime, which is how the game runs on devices, is smaller. 2D mobile games need to be quick to pick up and start so this is important to consider. Unity has a larger runtime, meaning games take up more storage and memory, which isn’t ideal on mobile since it results in lag and long loading times.

The development process on Cocos and Unity for mobile games varies due to their asset availability and physics engines. Unity’s large asset store comes with ready-made sprites, sounds and tools to speed up development. Unity’s physics engines include Box2D and PhysX for both 2D and 3D capabilities as well.

Cocos doesn’t have a large asset store, so devs need to build or source the assets on their own, but the open-source framework gives more flexibility to build in custom pipelines. Cocos uses Box2D as well as Chipmunk physics libraries, both of which are efficient for use in 2D games.

What kinds of games are created using Cocos and Unity?

Cocos is used to create 2D mobile games as it’s optimized for titles like Badlands that run smoothly on phones and tablets. Cross-platform 2D and 3D games are created using Unity instead, since it supports games running on PC, consoles and VR/AR.

Casual games that are lightweight and quick to pick up such as slot and casino games are built via Cocos due to its sprite-based efficiency. Sprite-based games are games with 2D animations and images for characters, such as AFK Arena. AFK uses 2D sprites for characters and their attack animations which is lighter on mobile than 3D animations.

Unity’s toolset gives leeway for both casual games, like Monument Valley, and large-scale AAA RPGs like Genshin Impact. The runtime of the engine is heavier as a result so it’s not as efficient for 2D mobile game development. Unity is instead ideal for platformers like Ori and the Blind Forest, which is a hybrid 2D and 3D game since it has tools for both sprite animation and 3D assets.

Which is better for beginners: Cocos vs Unity?

Unity is better for beginners as it comes with beginner-friendly visual tools and a large community. The asset store and tutorials online help ease beginners into using the engine, even though the varied toolset has advanced and complex features. Cocos is ideal for coders that want finer control and freedom since it’s open-source. Beginners that want to start with coding in game development are liable to go for Cocos instead.

Unity’s toolset includes an editor and drag-and-drop tools for visual scripting, which reduce the need for code. Users are able to drag in assets and add logic without programming, and the assets, (including sounds, shaders, and textures) are available in the Unity Asset store. The engine itself is complex, so it leans toward being overwhelming for complete beginners. Unity has tutorials on how to use its tools and UI to negate this, and the community is large and supportive, with plugins and forums to ease beginners into game development.

Cocos is lightweight with small runtimes and is open-source, and Cocos Creator’s visual editor is similar to Unity’s, easing onboarding for beginners. The overall use still requires more coding knowledge than needed when starting with Unity so beginners with no programming experience might struggle. Cocos’s community is comparatively small and centered in Asia, but their open-source contributions offer flexibility to devs. For beginners who prefer coding over visual tools, Cocos is recommended. The key takeaway is that Unity is easier to learn than Cocos.

Unity is easier to use as well since it lets beginners drag in sprites and add physics immediately. The workflow is streamlined, but there are advanced features that beginners might not need, like 3D rendering and AR/ VR. Cocos is efficient for 2D games but inconvenient when users lack coding skills even though Cocos Creator improves the usability.

What are the system requirements for Cocos vs Unity?

The system requirements for Cocos are a minimum Windows 7 OS with 4 GB RAM and any GPU that supports OpenGL. Unity needs a minimum Windows 10 OS with 8 GB RAM and a GPU capable of DX10+. A detailed overview of the minimum system requirements of Cocos and Unity (which runs on Linux as well) is provided below.

Cocos needs less demanding hardware and is able to run on lower-end PCs compared with Unity. The engine runtime is smaller as a result, whereas Unity might cause lag and performance delay on hardware not up to speed. Unity comes with licensing tiers, varying depending on Personal and Enterprise use, whereas Cocos is free and open-source.

What are the pros and cons of Cocos vs Unity?

The pros and cons of Cocos and Unity stem from their licensing fees, toolsets and community size. Cocos is lightweight and fully free and open-source so it’s ideal for 2D mobile game development and for devs on a budget, but the toolset is more limited. The table below provides an overview of the pros and cons of Cocos.

Unity’s toolset is more varied compared to Cocos, and beginner-friendly with the drag-and-drop tools but the UI and overall engine can overwhelm complete beginners. The pros and cons of Unity are laid out in the table below.
