[VisibleOnScreenEnabler3D] contains a box-shaped region of 3D space and a target node. The target node will be automatically enabled (via its [member Node.process_mode] property) when any part of this region becomes visible on the screen, and automatically disabled otherwise. This can for example be used to activate enemies only when the player approaches them.
|
|
See [VisibleOnScreenNotifier3D] if you only want to be notified when the region is visible on screen.
|
|
[b]Note:[/b] [VisibleOnScreenEnabler3D] uses an approximate heuristic that doesn't take walls and other occlusion into account, unless occlusion culling is used. It also won't function unless [member Node3D.visible] is set to [code]true[/code].

<member name="enable_mode" type="int" setter="set_enable_mode" getter="get_enable_mode" enum="VisibleOnScreenEnabler3D.EnableMode" default="0">
|
|
Determines how the target node is enabled. Corresponds to [enum Node.ProcessMode]. When the node is disabled, it always uses [constant Node.PROCESS_MODE_DISABLED].

<member name="enable_node_path" type="NodePath" setter="set_enable_node_path" getter="get_enable_node_path" default="NodePath("..")">
|
|
The path to the target node, relative to the [VisibleOnScreenEnabler3D]. The target node is cached; it's only assigned when setting this property (if the [VisibleOnScreenEnabler3D] is inside the scene tree) and every time the [VisibleOnScreenEnabler3D] enters the scene tree. If the path is empty, no node will be affected. If the path is invalid, an error is also generated.
