+# ESCBackground
+
+**Extends:** [TextureRect](../TextureRect)
+
+## Description
+
+ESCBackground's purpose is to display a background image and receive input
+events on the background. More precisely, the TextureRect under ESCBackground
+does not receive events itself - if it did, it would also eat all events like
+hotspot focusing and such. Instead, we set the TextureRect mouse filter to
+MOUSE_FILTER_IGNORE, and we use an Area2D node to receive the input events.
+
+If ESCBackground doesn't contain a texture, it is important that its rect_size
+is set over the whole scene, because its rect_size is then used to create the
+Area2D node under it. If the rect_size is wrongly set, the background may
+receive no input.
+
+## Property Descriptions
+
+### esc\_script
+
+```gdscript
+export var esc_script = ""
+```
+
+The ESC script connected to this background
+
+## Method Descriptions
+
+### manage\_input
+
+```gdscript
+func manage_input(_viewport, event, _shape_idx) -> void
+```
+
+Manage inputs reaching the Area2D and emit the events to the input manager
+TODO: Don't change private variables here, use an event for BUTTON_WHEEL
+
+#### Parameters
+- _viewport: (not used)
+- event: Event received
+- _shape_idx: (not used)
+
+### get\_full\_area\_rect2
+
+```gdscript
+func get_full_area_rect2() -> Rect2
+```
+
+Calculate the actual area taken by this background depending on its
+Texture or set size
+**Returns** The correct area size
