MeshInstance2D

繼承： Node2D < CanvasItem < Node < Object

用於在 2D 中顯示 Mesh 的節點。

說明

Node used for displaying a Mesh in 2D. This can be faster to render compared to displaying a Sprite2D node with large transparent areas, especially if the node takes up a lot of space on screen at high viewport resolutions. This is because using a mesh designed to fit the sprite's opaque areas will reduce GPU fill rate utilization (at the cost of increased vertex processing utilization).

When a Mesh has to be instantiated more than thousands of times close to each other, consider using a MultiMesh in a MultiMeshInstance2D instead.

A MeshInstance2D can be created from an existing Sprite2D via a tool in the editor toolbar. Select the Sprite2D node, then choose Sprite2D > Convert to MeshInstance2D at the top of the 2D editor viewport.
