- Descriptors sets are now independent from a set index. Camera matrices for example can be bound to set index 1 for the batching system but index 2 for compute shaders.
- Truly global descriptors sets (misc data, textures and light data) are now manually bound to a global static class that allows retrieval of these sets to be bound whenever in the middle end.
- Predefined descriptor set layouts (but not truly global such as camera data, materials and font) have their layouts predefined in a class and used for descriptor set initialization within the middle end. The sets themselves are allocated using these layouts (also accessible globally).
- Descriptor sets that are more flexible with their bindings such as render graph resources are introspected from shaders and not predefined at all (though their types are recorded in SHGraphicsPredefinedData to avoid magic numbers when binding descriptor sets in some systems).
- Systems now have fixed mappings for descriptors used in shaders and these are defined in SHGraphicsPredefinedData. Batching for example has 3 fixed descriptors: Static global bound at 0, camera data bound at 1, materials bound at 2.
- Viewports no longer contain renderers and renderers no longer contain render graphs. The graphics system only has 1 render graph and subpasses can have both viewports and renderers bound to them to have options for viewport/scissor and camera settings.
- Light data is now bound before every compute system.
- There is only 1 render graph in the entire system and contains only 6 nodes: G-Buffer pass (with lighting compute pass), debug draw with depth, debug draw, screen space pass, dummy pass for transition to input attachment for imGui and lastly the imGui pass for rendering editor to swapchain.
- All Shaders now take in a single projection matrix. The type of projection matrix is dependent on the SHRenderer projection type.
- SHGraphicsSystem now only has a single render graph.
- SHGlobalDescriptorSets now store a descriptor set for static global data and a handle to the lighting system. Functions to bind their descriptor sets are also available.
- Font desc set layout is added back into SHPredefinedData because while its possible to introspect the layouts from the shaders, the layouts is required beforehand to generate the font objects
- SHRenderers and SHViewport are now 2 separate entities, both passable to SHSubpass to be contained and used to set viewport/scissor and send camera matrices to shaders.
- SHRenderer descriptor sets are now updated separately from the binding. They happen directly before the render graph executes.
- AI now keeps track of last waypoint he has seen player at and heads there in an attempt to chase him down
- AI can be made to reverse his chase/patrol path by running around him
- The scene with the AI fix is called "MainGameWithAIFixed"
- Changed the input check in the jump function from a GetKeyDown() / GetKeyUp() to a GetKey() / !GetKey()
- This makes jumping a lot more responsive
- This also means holding the jump button causes the raccoon to "bunny hop" until jump button is released
