Struct PaintMaps 

pub struct PaintMaps { /* private fields */ }

All painted masks of the running editor / game, by name.

Implementations

impl PaintMaps

pub fn global() -> &'static PaintMaps

The process-wide registry (the renderer reads masks from here).

pub fn create(&self, name: &str, width: u32, height: u32)

Creates an empty mask (all base layer) unless one exists.

pub fn exists(&self, name: &str) -> bool

Whether a mask is loaded.

pub fn load_or_create(&self, name: &str, assets: &Assets, size: u32)

Loads paint/<name>.png from the project, or creates a fresh mask.

pub fn snapshot(&self, name: &str) -> Option<([u32; 2], Vec<u8>, u64)>

(size, pixels, version) of a mask, for uploading to the GPU.

pub fn restore(&self, name: &str, size: [u32; 2], rgba: Vec<u8>) -> bool

Restores an undo snapshot, incrementing the version so the renderer uploads it again. Rejects empty/oversized images and mismatched RGBA lengths without changing the map.

pub fn version(&self, name: &str) -> u64

Current version of a mask (0 when missing).

pub fn brush( &self, name: &str, uv: [f32; 2], radius: f32, strength: f32, hardness: f32, mode: BrushMode, )

Applies one brush dab at uv (0..1). radius is in uv units, strength 0..1 per dab, hardness 0 (soft falloff) .. 1 (hard edge).

pub fn fill(&self, name: &str, layer: usize)

Fills the whole mask with one layer (a quick base coat).

pub fn save_all(&self, assets_dir: &Path) -> usize

Writes every edited mask to <assets>/paint/<name>.png. Returns how many were saved.

pub fn dirty_names(&self) -> Vec<String>

Names of masks with unsaved edits.
