Godot vs O3DE: Pricing

Both Godot and O3DE are offered free of cost with open source licenses, enabling flexibility and a no-hidden-cost environment for developers.

Godot

Godot operates under an MIT license, providing an open-source interface. The engine allows developers to manipulate and tweak the code to meet their unique game development needs. Users own their games outright, with no licensing fees, contracts, or hidden costs. Godot’s commitment to open-source ideals fosters a cost-free and collaborative atmosphere in the game development community.

O3DE

O3DE, short for Open 3D Engine, is also an open-source game development tool. It operates under the Apache License, Version 2.0, and MIT license. This allows developers to use, modify, and distribute their creations without any charges. O3DE facilitates free and open source use entailing zero licensing costs.

Code Examples for Godot & O3DE

Godot: Automated Sprite Motion

This snippet displays an automated sprite motion for a basic game avatar in Godot. The sprite moves horizontally, reverses direction upon reaching screen edges. It requires a 2D sprite named ‘Sprite’ and an additional script file attached to it.

        extends Sprite
        var speed = 200
        var direction = 1

        func _ready():
            pass

        func _process(delta):
            var screen_width = get_viewport().size.x
            if position.x > screen_width - texture.get_width()/2:
                direction = -1
            elif position.x < texture.get_width()/2:
                direction = 1
            position.x += speed * direction * delta

O3DE: Basic AI Navigation

This snippet illustrates a basic AI character navigation in O3DE, following a navmesh. The character would follow the player if within a certain range. It is necessary to have AI framework SDK installed and AI controlled character prefab.

        #include "Core/Framework/Base/BaseComponent.h"
        #include "Core/Framework/Navigation/INavigationInterface.h"

        class AIComponent : public BaseComponent
        {
        public:
            virtual void Init() override;
            virtual void Update(float deltaTime) override;

        private:
            EntityId m_PlayerEntity;
            INavigationInterface* m_pNavigationInterface;
        };

        void AIComponent::Init()
        {
            m_pNavigationInterface = QueryNavigationInterface();
            m_PlayerEntity = QueryPlayerEntity();
        }

        void AIComponent::Update(float deltaTime)
        {
            Vector3 playerPos = m_pNavigationInterface->GetEntityPosition(m_PlayerEntity);
            Vector3 aiPos = m_pNavigationInterface->GetEntityPosition(GetOwnerEntity());

            if (Vector3::Distance(playerPos, aiPos) < 1000.0f)
            {
                m_pNavigationInterface->NavigateTo(GetOwnerEntity(), playerPos);
            }
        }
