UIOpacity Component References

The UIOpacity Component records a transparency modification flag for the node, which is used to influence all the render nodes inside its sub tree. Normally it's used on a non render nodes, otherwise its opacity will be multiplied with the render component's opacity. The render nodes can set transparency individually by setting the alpha channel of color.

The method of use is as follows:


You can also set transparency by code. Example:

const opacityComp = this.getComponent(UIOpacity);
opacityComp.opacity = 157;

To use UIOpacity, please refer to the UIOpacity API documentation and the Opacity scene of the test-cases-3d project.
