Function documentation

static affine_bg_pa_register_hbe_ptr bn::affine_bg_pa_register_hbe_ptr::create(affine_bg_ptr bg, const span<const affine_bg_mat_attributes>& attributes_ref)

Creates an affine_bg_pa_register_hbe_ptr which changes the attributes to commit to the first GBA register of an affine_bg_ptr.

Parameters
bg affine_bg_ptr to be modified.
attributes_ref Reference to an array of 160 affine_bg_mat_attributes objects with the attributes to commit to the first GBA register of an affine_bg_ptr in each screen horizontal line.
Returns The requested affine_bg_pa_register_hbe_ptr.

The attributes are not copied but referenced, so they should outlive affine_bg_pa_register_hbe_ptr to avoid dangling references.

static affine_bg_pa_register_hbe_ptr bn::affine_bg_pa_register_hbe_ptr::create(affine_bg_ptr bg, const span<const int16_t>& values_ref)

Creates an affine_bg_pa_register_hbe_ptr which changes the values to commit to the first GBA register of an affine_bg_ptr.

Parameters
bg affine_bg_ptr to be modified.
values_ref Reference to an array of 160 values to commit to the first GBA register of an affine_bg_ptr in each screen horizontal line.
Returns The requested affine_bg_pa_register_hbe_ptr.

The values are not copied but referenced, so they should outlive affine_bg_pa_register_hbe_ptr to avoid dangling references.
