# Creation Tips - Assets

## 📒<mark style="color:blue;">Asset Grouping</mark>

It is recommended to group and organize assets in the layer area based on categories or their functions after adding them to the canvas. This will make it easier for subsequent production tasks.

<mark style="color:red;">**What is the purpose of grouping?**</mark>

Firstly, it's important to understand that groups have a higher hierarchy than individual assets. Higher-level groups also have a higher hierarchy than lower-level groups. This means that adjustments made to a group will affect all the assets within it, and adjustments made to a higher-level group will affect all the lower-level groups and assets within it.

For example, when you hide the group of left-side props, the text and images within it will be hidden together. Similarly, when you hide the entire options group, the instructional text, finger pointing, and both prop groups underneath it will also be hidden.

Therefore, grouping assets appropriately:

1）Facilitates quick identification and locating of specific assets when dealing with a large number of assets. It helps in determining which part of the assets has issues.

2）Enables more efficient animation and event setup. Instead of individually setting the same animation/event on each asset, you can set it on the group, saving time and effort.

3）Facilitates screen adaptation for the entire group of assets and allows adjustments to the landscape layout. After completing the vertical layout, when transitioning to the landscape mode, select the main group and click the "Reuse vertical screen position configuration" button to apply the layout with a single click.

## 📒<mark style="color:blue;">Effect Implementation</mark>

### 1.How to create "Mirror & Reflection"?

Approach: Mirror effect is achieved by horizontal flipping, while reflection effect is achieved by vertical flipping. Adjust the scale of the corresponding layer in the appearance parameters.

1）Select the layer you want to adjust.

2）In the parameter setting area on the right side, modify the scale:

* Mirror Effect: Adjust the value of "Scale X" in the "Scale" to -1.

* Reflection Effect: Adjust the value of "Scale Y" in the "Scale" to -1.
