swift – 在Xcode 8中为SKTileMapNode的tile添加物理

选项1：将SKNodes应用于地图上每个图块的每个位置,并根据该图块的内容和状态将适当的物理实体应用于该SKNode.

选项2：使用每个图块的位置信息将一个物理实体数组添加到SKTileMapNode,并相应地定位它们.

我想象一个重力下降,马里奥风格的平台游戏,这种地形需要物理机构的地面：

摘自苹果公司WWDC关于瓷砖和物理学的成绩单：

And you’ll note that I’m colliding with the tiles here.

And I achieve this by leveraging custom user data that we can put on
each of our tiles.

Here,I’ll show you in our tile set.

Select one of the variants here.

And you can see that we have some user data over here.

And I just have a value called edgeTile which is a Boolean,and I set
to 1.

So,in code,I’m going through the tile map in our platform demo here,
and I’m looking for all of these edge tiles.

And whenever I find one,I create some physics data to allow the
player to collide with it.

And since it is just in our tile map here,say I wanted to get over
this large wall here.

When I run the game,you’ll see that my guy can’t actually jump high
enough to get over it.

And he really wants to because that red button over there looks really
tempting.

I really want to push that thing.

So,since we’re just generating our physics data from our tiles and
our user data,all we can do is just going here and erase these tiles
and build and run our game again.

The tiles are now gone and we can now move through there.

And we didn’t have to change code or anything.

We just used the data that we pulled from the tile map to set up our
tile.

It’s that simple.

听起来很简单,但是比我的想法要大得多,弄清楚正在做什么,以及如何做.
