Root Cause

A TilemapCollider2D component is added to a Tilemap that has no tiles placed, causing the collider to compute empty bounds.

generic

中文

TilemapCollider2D 组件添加到了没有放置任何瓦片的瓦片地图上，导致碰撞体计算出空边界。

Workarounds

  1. 95% success Add at least one tile to the Tilemap using the Tile Palette or script: `tilemap.SetTile(new Vector3Int(0, 0, 0), yourTile);`. 
    Add at least one tile to the Tilemap using the Tile Palette or script: `tilemap.SetTile(new Vector3Int(0, 0, 0), yourTile);`.
  2. 90% success Remove the TilemapCollider2D component if the tilemap is meant to be empty, or use a CompositeCollider2D with a separate collider setup. 
    Remove the TilemapCollider2D component if the tilemap is meant to be empty, or use a CompositeCollider2D with a separate collider setup.

中文步骤

  1. 使用瓦片调色板或脚本在瓦片地图上至少放置一个瓦片：`tilemap.SetTile(new Vector3Int(0, 0, 0), yourTile);`。
  2. 如果瓦片地图应为空，则移除 TilemapCollider2D 组件，或使用 CompositeCollider2D 配合独立的碰撞体设置。

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Disabling and re-enabling the collider does not fix the empty bounds; the collider still has no tiles to compute from.

  2. 90% fail

    Setting the Tilemap's cell size to zero or negative values may cause other errors but not resolve the empty bounds.
