* 看了一下下面的代码，加了打印 `D` 的第一次赋值是 `nil` 接下来的第二次赋值还是 `nil`
```
local function shadow_changed()
local C = irq.main_camera_changed()
local D = w:first "make_shadow scene_changed directional_light"
local sbe = w:first "scene_bounding_changed"
if C or D or sbe then
if C then
w:extend(C, "camera:in scene:in")
else
C = irq.main_camera_entity "camera:in scene:in"
end
if D then
w:extend(D, "scene:in")
else
D = w:first "make_shadow directional_light scene:in"
end
if sbe then
w:extend(sbe, "shadow_bounding:in")
else
sbe = w:first "shadow_bounding:in"
end
return true, C, D, sbe.shadow_bounding
end
end
```
* 求指导一下怎么跑起来
