v0.2.0

This release was focused on improving the coding experience when creating atta projects. Six projects were created:

• Boids #29
• Tutorial #30
• Robotic Arm GA #31
• Ants #32
• Bee hive finding #33
• Game of life #36

Note: You can run any example in your browser 😃

Changelog

• Feat
  • RGBA image support with transparent background
  • cmp::Factory::getFirstClone()
  • cmp::Factory::getLastClone()
  • gfx::Drawer::clear(StringId group) - clear all objects of a specific group
• Refactor
  • Removed buggy shortcuts to start/play/pause/stop simulation
  • Only serialize components that are being used to make the .atta smaller
  • Print cmake output while building
  • Now we also have cmp::Material::setResource, to be consistent with cmp::Material::getResource
  • Quaternion methods: setEuler, getEuler, setAngle2D, getAngle2D, setAxisAngle
  • cmp::getPrototypeFactory(cmp::Entity) -> cmp::getFactory(cmp::Entity)
  • Removed logging used to debug atta
• Fix
  • Mesh combo not being shown
  • Mesh sid now is set to first mesh resource when created
  • Script sid now is set to first script when created
  • Material component imgui not showing variable names
  • Viewport name being messed up
  • Create .atta file if is doesnt exists
  • Project::onLoad was being called before project file deserialization
  • ImPlot without context
  • Now scr::ProjectScript::onLoad is called only after the components are deserialized from the .atta file
  • scr::ProjectScript::onLoad was not being called for static projects
  • Now it is possible to use literal ""_sid without being in the atta scope
  • Crash when material name is empty
  • Scripts not being loaded
  • Glad include not found
  • Web build not able to find files
  • Web wrong relationship deserialization

v0.1.0

General improvement in the codebase and handling project files. The most important changes were:

• File serializer: Refactor file serializer (.atta) to be flexible enough for future releases #13
• Atta versions: Handle atta projects with different version (ignore and open with current version or restart atta with correct version) #18
• Project web build: Should be possible to open projects with the web build #19
• Http interface: Basic HTTP interface support #15
• Image resource: Refactor image resource to be able to create/update with code #24
• Material resource: Refactor MaterialComponent to use a MaterialResource #35
• Component interface: Refactor the component module interface to be easier to use the components and entities #34

The codebase was also refactored for each module to have its own namespace and follow the same formatting style (.clang-format). Also, each module now provides an interface to be less verbose.

v0.0.3

This release should be used to open atta projects developed with the v0.0.3, as major changes will be made in v0.1.0.
