`sa` · 扩展 `NewOpcodes` · 需 CLEO + NewOpcodes
部件父节点、RpAtomic 显隐与材质。写法见 [Lua](/docs/cleo/syntax) / [Redux](/docs/cleo/syntax-redux)。
## Component
取部件的父 frame。
```text
0D74 GET_COMPONENT_PARENT_COMPONENT
in: self
out: parentComponent
```
```lua
local parent = getComponentParentComponent(comp)
```
```js
const parentComponent = Component.getParentComponent(self)
```
取部件下 RpAtomic 数量。
```text
0D75 GET_COMPONENT_NUM_OBJECTS
in: self
out: numObjects
```
```lua
local n = getComponentNumObjects(comp)
```
```js
const numObjects = Component.getNumObjects(self)
```
按索引取部件下的 atomic。用在 `if` 里。
```text
0D76 GET_COMPONENT_OBJECT
in: component, object
out: componentObject
```
```lua
if getComponentObject(comp, 0) then
end
```
```js
if (native(0x0D76, component, object)) {
}
```
## Atomic 显隐 / 材质
隐藏(1) / 显示(0) atomic（改 render flags）。
```text
0D77 HIDE_OBJECT_ATOMIC
in: objectAtomic, hide
```
```lua
hideObjectAtomic(atomic, true)
```
```js
native(0x0D77, objectAtomic, hide)
```
读 atomic 上某可见性 flag。
```text
0D78 GET_OBJECT_ATOMIC_FLAG
in: object, atomicFlag
out: state
```
```lua
local on = getObjectAtomicFlag(obj, flag)
```
```js
const state = native(0x0D78, object, atomicFlag)
```
设 / 清 atomic 可见性 flag。
```text
0D79 SET_OBJECT_ATOMIC_FLAG
in: object, atomicFlag, state
```
```lua
setObjectAtomicFlag(obj, flag, true)
```
```js
native(0x0D79, object, atomicFlag, state)
```
取 atomic geometry 材质数。用在 `if` 里。
```text
0D7A GET_OBJECT_ATOMIC_NUM_MATERIALS
in: object
out: numMaterials
```
```lua
if getObjectAtomicNumMaterials(atomic) then
end
```
```js
if (native(0x0D7A, object)) {
}
```
按材质下标取贴图指针。用在 `if` 里。
```text
0D7B GET_OBJECT_ATOMIC_MATERIAL_TEXTURE
in: object, material
out: texture
```
```lua
if getObjectAtomicMaterialTexture(atomic, 0) then
end
```
```js
if (native(0x0D7B, object, material)) {
}
```
