GodotEngine：用Sprite3D派生了一个Canvas3D类用于实现3D中的UI显示

Godot Engine中在3D世界显示2D的UI&＃xff0c;需要用到Viewport&＃xff0c;整个操作步骤还是有些麻烦&＃xff0c;所以我用Sprite3D派生了一个Canvas3D类用于实现3D中的UI显示

代码如下

extends Sprite3Dclass_name Canvas3Dexport var viewport_path:NodePath &＃61; "viewport"func _ready():var viewport &＃61; get_node_or_null(viewport_path)if is_instance_valid(viewport) and viewport is Viewport:self.billboard &＃61; SpatialMaterial.BILLBOARD_ENABLEDself.texture &＃61; viewport.get_texture()viewport.usage &＃61; Viewport.USAGE_2Dviewport.transparent_bg &＃61; trueviewport.render_target_v_flip &＃61; trueelse:push_error("a valid viewport should be assigned!")
