UIOpacity Component References

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.

Note: this component is only functional when its root node have Canvas component or RenderRoot2D component.

The method of use is as follows:


You can also set transparency by code. Example:

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