Hello !
I created a simple function that aims to change the opacity of a block from 100 to 50 by using a variable.
I tested the function and there is a problem : the opacity of my block doesn’t change…
All the parts of my blocks work individually but not when I put them together…
If anyone can help me, it would be most welcome !
Here is my block:

Hi, welcome to Thunkable!
What is the starting rgba value for that group’s background color?
Just to be clear: setting the opacity for a group is only going to affect the background color of the group. It’s not going to affect the components inside the group. At least that’s my assumption based on what I know about groups. It would be nice if it did affect all embedded components.
Can you post a link to a simple project that demonstrates the issue you’re seeing?

The `Group` component has its own opacity option. Use this one not the opacity of the color.

I only see “touch opacity” and changing that doesn’t seem to do anything. Where are you seeing a group opacity property?

This code fades the background color:

Yes, this is the one. If you set the `touch opacity` to 100 then when you click on the group object it will not reveal what’s under it.
This is a new addition.

You can set it in the blocks and in the design panel as well! 🙂

Right but this is only related to a touch/click event, yes? So if you wanted to fade the opacity of a group without detecting a touch, you couldn’t.

Yes that’s what I was looking for.
Thanks a lot for your help !!!
