我正在尝试使用Unity中的box collider功能，但它似乎已被弃用。
我收到消息：
//Move each wall to its edge location:
topWall.size = new Vector2 (mainCam.ScreenToWorldPoint (new Vector3 (Screen.width * 2f, 0f, 0f)).x, 1f);
topWall.center = new Vector2 (0f, mainCam.ScreenToWorldPoint (new Vector3 ( 0f, Screen.height, 0f)).y + 0.5f);
bottomWall.size = new Vector2 (mainCam.ScreenToWorldPoint (new Vector3 (Screen.width * 2, 0f, 0f)).x, 1f);
bottomWall.center = new Vector2 (0f, mainCam.ScreenToWorldPoint (new Vector3( 0f, 0f, 0f)).y - 0.5f);
leftWall.size = new Vector2(1f, mainCam.ScreenToWorldPoint(new Vector3(0f, Screen.height*2f, 0f)).y);;
leftWall.center = new Vector2(mainCam.ScreenToWorldPoint(new Vector3(0f, 0f, 0f)).x - 0.5f, 0f);
rightWall.size = new Vector2(1f, mainCam.ScreenToWorldPoint(new Vector3(0f, Screen.height*2f, 0f)).y);
rightWall.center = new Vector2(mainCam.ScreenToWorldPoint(new Vector3(Screen.width, 0f, 0f)).x + 0.5f, 0f);
//Move the players to a fixed distance from the edges of the screen:
Player01.position.x = mainCam.ScreenToWorldPoint (new Vector3 (75f, 0f, 0f)).x;
Player02.position.x = mainCam.ScreenToWorldPoint (new Vector3 (Screen.width -75f, 0f, 0f)).x;
我一直试图将Walls设置在屏幕的边缘。这是代码：
TopWall BottomWall，LeftWall，RightWall和BoxCollider2D当然都属于Item.aggregate([
{ $unwind: '$dummy'},
{ $match: {'dummy.storage': {$gt: 0}} },
{ $group: {_id: '$_id',
dummy: {$push: '$dummy'},
original_y: { $first: "$original_y" },
new_y: { $first: "$new_y" },
}},
{$project:{
original_y: 1, new_y: 1,
tallyAmount: {$sum: ["$new_y","$original_y"] }
}
},
]
)
.exec(function(err, results){
if(err)
{
console.log("Error : " + err);
return res.json ({error: "Error"});
}
else if(!(results) || results == null || results.length == 0)
{
console.log("No Results Found");
return res.json ({error: "No Results Today"});
}else{
res.send(results);
}
});
类型。
如何更改代码以避免收到此错误消息？谢谢你的帮助。

＆＃34; BoxCollider2D.center已被弃用。请改用BoxCollider2D.offset＆＃34;
替换：
topWall.center = new Vector2 (0f, mainCam.ScreenToWorldPoint (new Vector3 ( 0f, Screen.height, 0f)).y + 0.5f);
使用：
topWall.offset = new Vector2 (0f, mainCam.ScreenToWorldPoint (new Vector3 ( 0f, Screen.height, 0f)).y + 0.5f);
当然，这也会改为BottomWall，LeftWall和RightWall。
