Agbrs Agb Versions Save

Added

• .abs() on Vector2D and Rect

Fixed

• InfiniteScrolledMap can now scroll more than 1 tile in a single frame without corrupting.

Added

• Added .priority(), .set_priority() and .is_visible() to RegularMap, AffineMap and InfiniteScrolledMap.
• Replaced .show() and .hide() with .set_visible()in RegularMap, AffineMap and InfiniteScrolledMap.
• Added .into_inner() to InfiniteScrolledMap to get the map back once you are done using it in the InfiniteScrolledMap.
• Added .hflip(), .vflip(), .priority(), .position() to ObjectUnmanaged and Object.
• An abstraction over hblank DMA to allow for cool effects like gradients and circular windows. See the dma_effect* examples.
• Expermental and incomplete support for MIDI files with agb-tracker.
• Fixnum now implements num::Num from the num crate.
• Default implementations for RandomNumberGenerator, InitOnce and RawMutex.

Changed

• A few functions which previously accepted a Vector<u16> now accept an impl Into<Vector2D<u16>> instead.

Added

• You can now use include_aseprite and include_background_gfx to include files from the out directory using the $OUT_DIR token (thanks @screenshakes)
• Added .pause() and .resume() methods to SoundChannels to let you pause and resume from where you left off.

Added

• There is now a multiboot feature which you can use to easily make multiboot ROMs.
• Can now set palette on a TileSetting struct.

Changed

• You no longer need the gba.ld or gba_mb.ld files in your repository. You should delete these when upgrading.

Fixed

• Multiboot builds now work on mgba.
• Fixed inaccuracy in cosine implementation caused by accidentally multiplying correction term by zero.

Fixed

• Fixed the build on docs.rs.

Added

• New tracker for playing XM files (see the agb-tracker crate).
• You can now declare where looping sound channels should restart.
• Fixnums now have constructors from_f32 and from_f64. This is mainly useful if using agb-fixnum outside of the Game Boy Advance e.g. in build scripts or macros.
• New option when loading a background to automatically deduplicate tiles.
• Methods on tile_setting to toggle its hflip and vflip status.

Changed

• Sound channel panning and volume options are now Num<i16, 8> rather than Num<i16, 4> for improved precision and sound quality.
• Due to dependency changes, agb-gbafix is now released under MPL rather than GPL.
• include_background_gfx! now produces tile sets and tile settings directly.

Fixed

• 256-colour backgrounds are better supported.
• Mono looping samples will now correctly play to the end if it doesn't perfectly align with a buffer boundry and short samples now also loop correctly.
• Fixed a bug in bitmap4 that caused setting pixels to be always incorrect.

A post GMTK update! The key feature being that there is no need for the binutils and agb can be used with only nightly rust.

Added

• New include_palette macro for including every colour in an image as a u16 slice.
• New object based text renderer.

Changed

• Changed the default template game.
• DynamicSprite has a new API which changes the constructor and adds a set_pixel and clear methods.
• You no longer need to install arm-none-eabi-binutils. In order to write games using agb, you now only need to install rust nightly.
• 10% performance improvement with the software mixer.

Fixed

• Compile error if you tried to import a larger sprite which uses more than 15 colours between frames.

Added

• You can now import aseprite files directly (in addition to the already supported png and bmp files) when importing background tiles.
• New additional unmanaged object API for interacting with a more straightforward manner with the underlying hardware.

Changed

• Importing background tiles has been improved. You no longer need to use include_gfx! with the toml file. Instead, use include_background_gfx. See the documentation for usage.
• The hashmap implementation is now it its own crate, agb-hashmap. There is no change in API, but you can now use this for interop between non-agb code and agb code
• Moved the existing object API to be the OamManaged API. The old names persist with deprecated notices on them.

Added

• Added custom gbafix implementation which can take the elf file produced by cargo build directly, removing the need for the objcopy step.

Changed

• Made Vector2D::new a const function.
• The template now uses rust 2021 edition by default.
• All objects which should only be created once now have the correct lifetimes to only allow one to exist.
• Template now uses codegen-units=1 to workaround bug in nightly.
• Allocator is no longer interrupt safe.
• Soundness issues with interrupts resolved which makes them unsafe and require the closure to be static (breaking change).

Fixed

• Alpha channel is now considered by include_gfx!() even when transparent_colour is absent.
• 256 colour backgrounds are now correctly rendered (breaking change).
• The #[agb::entry] macro now reports errors better.
• Added the shstrtab section to the linker to ensure that agb builds with lld.

Added

• Added missed implementations of regular() and affine() to Tiled1 which made Tiled1 impossible to use.

Changed

• Text renderer can now be re-used which is useful for rpg style character/word at a time text boxes.
• Audio now automatically uses interrupts, so you can remove the setup_interrupt_handler or after_vblank calls to the mixer.
• If a vblank happens outside of wait_for_vblank, then next call will immediately return.

Fixed

• Zero volume now plays no sound.
• Fixed issue where volume was incorrect for volumes which were powers of 2.
