Kengine 5.0

This release comes with a ZIP file containing the entire source code, including its putils submodule. This makes it easier for people not used to working with Git submodules to download the entire source code.

Changelog

Major changes

• Improved reflection API
• Removed load/save functionality

"System Entity' model

• Systems are now represented by Entities with "function Components"
• Datapackets have been replaced by "function Components"
• This lets systems be queried and extended by users (by adding new "function Components" or any other type of components, e.g. for profiling)

"Type Entities"

• Replaced ComponentFunctions with "meta Components", attached to type Entities

Minor changes

Behaviors

• OpenGL sprites and text are now drawn upright

• Editor windows are named according to NameComponent

Components

• Replaced ModelLoaderComponent with ModelDataComponent

• Grouped parameters in InputComponent callbacks
• loop field in AnimationComponent
• Add pitch, yaw and roll to PhysicsComponent
• Replace PhysicsComponent::kinematic with KinematicComponent
• Light constants are now set in LightComponents instead of through global adjustables
• TextureModelComponent now stores the file name, is not used in combination with ModelComponent
• Updated putils::Point API

Misc

• Replaced putils_for_each_type macro with a function

Optimizations

• Added LuaTableComponent to separate responsibility from LuaComponent and have it not be tied to sol
• Optimized for empty components (no memory allocation)

Fixes

• Fixed ImGuiAdjustableSystem not loading colors properly
• Fixed crash in OpenGLSystem when requesting the Entity::ID for pixel in y == 0
• Fixed camera orientation in OpenGLSystem
