MeshLibrary
继承： Resource < RefCounted < Object
Library of meshes.
描述
A library of meshes. Contains a list of Mesh resources, each with a name and ID. Each item can also include collision and navigation shapes. This resource is used in GridMap.
方法
方法说明
void clear ( )
Clears the library.
void create_item ( id: int )
Creates a new item in the library with the given ID.
You can get an unused ID from get_last_unused_item_id.
int find_item_by_name ( name: String ) const1
Returns the first item with the given name, or -1 if no item is found.
PackedInt32Array get_item_list ( ) const1
Returns the list of item IDs in use.
Mesh get_item_mesh ( id: int ) const1
Returns the item's mesh.
Transform3D get_item_mesh_transform ( id: int ) const1
Returns the transform applied to the item's mesh.
String get_item_name ( id: int ) const1
Returns the item's name.
int get_item_navigation_layers ( id: int ) const1
Returns the item's navigation layers bitmask.
NavigationMesh get_item_navigation_mesh ( id: int ) const1
Returns the item's navigation mesh.
Transform3D get_item_navigation_mesh_transform ( id: int ) const1
Returns the transform applied to the item's navigation mesh.
Texture2D get_item_preview ( id: int ) const1
When running in the editor, returns a generated item preview (a 3D rendering in isometric perspective). When used in a running project, returns the manually-defined item preview which can be set using set_item_preview. Returns an empty Texture2D if no preview was manually set in a running project.
Array get_item_shapes ( id: int ) const1
Returns an item's collision shapes.
The array consists of each Shape3D followed by its Transform3D.
int get_last_unused_item_id ( ) const1
Gets an unused ID for a new item.
void remove_item ( id: int )
Removes the item.
void set_item_mesh ( id: int, mesh: Mesh )
Sets the item's mesh.
void set_item_mesh_transform ( id: int, mesh_transform: Transform3D )
Sets the transform to apply to the item's mesh.
void set_item_name ( id: int, name: String )
Sets the item's name.
This name is shown in the editor. It can also be used to look up the item later using find_item_by_name.
void set_item_navigation_layers ( id: int, navigation_layers: int )
Sets the item's navigation layers bitmask.
void set_item_navigation_mesh ( id: int, navigation_mesh: NavigationMesh )
Sets the item's navigation mesh.
void set_item_navigation_mesh_transform ( id: int, navigation_mesh: Transform3D )
Sets the transform to apply to the item's navigation mesh.
void set_item_preview ( id: int, texture: Texture2D )
Sets a texture to use as the item's preview icon in the editor.
void set_item_shapes ( id: int, shapes: Array )
Sets an item's collision shapes.
The array should consist of Shape3D objects, each followed by a Transform3D that will be applied to it. For shapes that should not have a transform, use Transform3D.IDENTITY.
