We don't use that info for anything, and it generates unnecessary diffs every time we bump the minor version (and CI failures if we forget to sync some files from opt-in modules (mono, text_server_fb).

|
Casts light in a 2D environment. A light is defined as a color, an energy value, a mode (see constants), and various other parameters (range and shadows-related).

<member name="range_item_cull_mask" type="int" setter="set_item_cull_mask" getter="get_item_cull_mask" default="1">
|
|
The layer mask. Only objects with a matching [member CanvasItem.light_mask] will be affected by the Light2D. See also [member shadow_item_cull_mask], which affects which objects can cast shadows.
|
|
[b]Note:[/b] [member range_item_cull_mask] is ignored by [DirectionalLight2D], which will always light a 2D node regardless of the 2D node's [member CanvasItem.light_mask].

|
</member>
|
|
<member name="shadow_filter_smooth" type="float" setter="set_shadow_smooth" getter="get_shadow_smooth" default="0.0">
|
|
Smoothing value for shadows. Higher values will result in softer shadows, at the cost of visible streaks that can appear in shadow rendering. [member shadow_filter_smooth] only has an effect if [member shadow_filter] is [constant SHADOW_FILTER_PCF5] or [constant SHADOW_FILTER_PCF13].

<member name="shadow_item_cull_mask" type="int" setter="set_item_shadow_cull_mask" getter="get_item_shadow_cull_mask" default="1">
|
|
The shadow mask. Used with [LightOccluder2D] to cast shadows. Only occluders with a matching [member CanvasItem.light_mask] will cast shadows. See also [member range_item_cull_mask], which affects which objects can [i]receive[/i] the light.

<constants>
|
|
<constant name="SHADOW_FILTER_NONE" value="0" enum="ShadowFilter">
|
|
No filter applies to the shadow map. This provides hard shadow edges and is the fastest to render. See [member shadow_filter].
|
|
</constant>
|
|
<constant name="SHADOW_FILTER_PCF5" value="1" enum="ShadowFilter">
|
|
Percentage closer filtering (5 samples) applies to the shadow map. This is slower compared to hard shadow rendering. See [member shadow_filter].
|
|
</constant>
|
|
<constant name="SHADOW_FILTER_PCF13" value="2" enum="ShadowFilter">
|
|
Percentage closer filtering (13 samples) applies to the shadow map. This is the slowest shadow filtering mode, and should be used sparingly. See [member shadow_filter].
|
|
</constant>
|
|
<constant name="BLEND_MODE_ADD" value="0" enum="BlendMode">
|
|
Adds the value of pixels corresponding to the Light2D to the values of pixels under it. This is the common behavior of a light.
|
|
</constant>
|
|
<constant name="BLEND_MODE_SUB" value="1" enum="BlendMode">
|
|
Subtracts the value of pixels corresponding to the Light2D to the values of pixels under it, resulting in inversed light effect.
|
|
</constant>
|
|
<constant name="BLEND_MODE_MIX" value="2" enum="BlendMode">
|
|
Mix the value of pixels corresponding to the Light2D to the values of pixels under it by linear interpolation.
|
|
</constant>
