AR框架解锁了新型的游戏玩法和用户交互。 这里有一些实用的想法可以激发您的灵感。 我们鼓励您与社区分享您自己的创作-我们将积极寻找出色的例子！
Back in 2003, Konami released the Game Boy Advance title, Boktai: The sun is in your hands. The physical cartridge included a light sensor that you needed to expose to sunlight in order to charge your in-game weapon. Now, using light estimation in mobile AR frameworks like ARCore 1.0 for Unity, it’s possible to create gameplay just like that without the need of additional hardware — giving you access to millions of users with AR-enabled devices!
早在2003年，Konami发行了Game Boy Advance游戏名称Boktai：太阳在您的手中 。 物理弹药箱包含一个光传感器，您需要将其暴露在阳光下才能为游戏中的武器充电。 现在，在AR的移动AR框架(如ARCore 1.0 for Unity)中使用光照估算，就可以像这样创建游戏玩法，而无需其他硬件-使您能够使用支持AR的设备访问数百万用户！
Today, Unity developers can bring new forms of user interaction to life leveraging not only light-estimation, but features like motion tracking and environmental understanding.
今天，Unity开发人员不仅可以利用光线估计，还可以利用运动跟踪和环境理解等功能，将新的用户交互形式带入生活。

The following are some of the features that help you get creative with AR.
以下是一些可帮助您增强AR创意的功能。
环境理解 (Environmental Understanding)
ARCore 1.0 for Unity provides a default grid that changes color for each new plane that it finds. You can easily modify the plane rendering by swapping out the TriGrid material texture.
ARCore 1.0 for Unity提供了一个默认网格，该网格会为找到的每个新飞机改变颜色。 您可以通过换出TriGrid材质轻松地修改平面渲染。

If you want to modify the rendering further, you can change a single line of code in the PlaneGrid shader, you can also change the texture to one with transparency by returning the _GridColor * col. The colors are chosen randomly from an array in TrackedPlaneVisualizer.cs, so check that out if you have specific colors you want to use.
如果要进一步修改渲染，可以在PlaneGrid着色器中更改一行代码，还可以通过返回_GridColor * col将纹理更改为具有透明性的纹理。 颜色是从TrackedPlaneVisualizer.cs中的数组中随机选择的，因此请检查是否有要使用的特定颜色。

Don’t only superimpose digital objects, modify and change the planes to give your app a unique look!
不仅要叠加数字对象，还要修改和更改平面以使您的应用具有独特的外观！
定向点 (Oriented points)
With oriented points, objects can be stuck to all different types of surfaces at any angle. You can take ARCore outside and start to liven up the world.
通过定向点，可以将对象以任何角度粘贴到所有不同类型的表面上。 您可以将ARCore带到外面，并开始生活。

Android吉祥物使用面向的特征点固定在树上。
Another unique use-case takes advantage of the way we render AR by lining up objects on either side of a wall to create an x-ray effect.
另一个独特的用例利用了我们渲染AR的方式，即将墙壁两侧的对象对齐以创建X射线效果。
Two virtual studs places on the wall then viewed from the opposite side
从墙的另一侧观察两个虚拟钉在墙上的位置
光线估算 (Light Estimation)
ARCore returns an ambient light value based on overall intensity of the pixels in the current camera frame. The SDK has special shaders that allow you to easily make any object’s shading adjust to its current environment. You can use take advantage of this to create a unique effect in which characters react to their current environment, as shown below.
ARCore根据当前相机帧中像素的整体强度返回环境光值。 SDK具有特殊的着色器，可让您轻松地将任何对象的阴影调整为适合其当前环境。 您可以利用这一点来创造独特的效果，使角色对当前环境做出React，如下所示。
The flower is sad because the ambient light-value is low.
这朵花很难过，因为环境光值低。
The flower becomes happy when the ambient light value increases.
当环境光值增加时，花朵就会变得快乐。
运动追踪 (Motion Tracking)
Motion tracking will play an increasingly important role in mobile AR apps. Imagine using proximity and motion as key drivers for minor interactions in your application, as demonstrated below.
运动跟踪将在移动AR应用程序中扮演越来越重要的角色。 想象一下，将接近度和运动用作应用程序中次要交互的关键驱动力，如下所示。
When the user gets close enough to a Cutie, it will trigger the wink animation.
当用户足够接近可爱时，它将触发眨眼动画。
Motion tracking is not limited to a small space, either. The device moves through the world understanding its own orientation and position. You can allows users to record motion paths simply drop markers behind them to retrace their path (as shown below).
运动跟踪也不限于很小的空间。 该设备在世界范围内移动，了解其自身的方向和位置。 您可以允许用户记录运动路径，只需在其后面放置标记即可追溯其路径(如下所示)。
Every meter a marker is dropped allowing a user to retrace their steps later.
每米都会放下一个标记，允许用户稍后追溯其步伐。
