Struct EffectGraph 

Source 
pub struct EffectGraph {
    pub header: EffectHeader,
    pub properties: Vec<PropertyDef>,
    pub texture_slots: Vec<TextureSlotDef>,
    pub nodes: Vec<GraphNode>,
    pub stacks: Vec<GraphStack>,
    pub links: Vec<GraphLink>,
    pub next_id: u32,
}
Expand description

The semantic graph: header, properties, nodes, stacks, and links.

Plus the monotonic id allocator. Diff-friendly and layout-free.

Fields§

§header: EffectHeader§properties: Vec<PropertyDef>§texture_slots: Vec<TextureSlotDef>

Host-supplied texture slots, ordered by sampling index.

Referenced by ImageBinding::Slot via stable SlotId and filled per-instance by the host game through bevy_hanabi::EffectMaterial. Asset-bound images are pinned on their source node and do not appear here. Empty for an effect with no host-supplied textures.

§nodes: Vec<GraphNode>§stacks: Vec<GraphStack>§links: Vec<GraphLink>§next_id: u32

Next id to hand out; only ever increases. Ids are never recycled so that links and persisted layout stay valid across edits and reloads.

Implementations§

Source§

impl EffectGraph

Source

pub fn empty() -> Self

An empty graph with a default header.

A placeholder for documents whose graph is not yet populated (e.g. a legacy EffectAsset opened before the import path exists). Carries no nodes, stacks, links, or properties.

Source

pub fn alloc_node_id(&mut self) -> NodeId

Mint a fresh, never-before-used NodeId.

Source

pub fn alloc_stack_id(&mut self) -> StackId

Mint a fresh, never-before-used StackId.

Drawn from the same counter as node ids so the two id spaces never collide.

Source

pub fn alloc_property_id(&mut self) -> PropertyId

Mint a fresh, never-before-used PropertyId.

Drawn from the same counter as node and stack ids so the three id spaces never collide.

Source

pub fn alloc_slot_id(&mut self) -> SlotId

Mint a fresh, never-before-used SlotId.

Drawn from the same counter as node, stack, and property ids so the four id spaces never collide.

Source

pub fn node(&self, id: NodeId) -> Option<&GraphNode>

Source

pub fn node_mut(&mut self, id: NodeId) -> Option<&mut GraphNode>

Source

pub fn stack(&self, group: ModifierGroup) -> Option<&GraphStack>

Source

pub fn property(&self, id: PropertyId) -> Option<&PropertyDef>

Source

pub fn texture_slot(&self, id: SlotId) -> Option<&TextureSlotDef>

Source

pub fn texture_slot_index(&self, id: SlotId) -> Option<usize>

Sampling index of a texture slot (its position in texture_slots), by id.
