Buttons and Functions

🎯 Is a Button a Function?

Yes! Every time you create a button on your HUD, you’re also creating a function associated with it. Let’s break it down step by step:

---

🧱 Creating a Function from a Button

1. In Second Life, create a prim that will serve as your button.

2. Give it a clear and structured name, like: button_texture_1, button_color_blue, etc.

3. Then, go to your creation panel (HUD).

4. In the panel, you'll see a list of buttons on the left side of the screen.

5. Click the button name.

✅ Done! A function with the same name as the button is automatically created, ready to be configured with any desired action.

🧠 Types of Functions

For advanced users, the system offers two types of functions:

---

🔗 Associative Function

This is the most common type. It is directly linked to a button or event, meaning:

• The function name is identical to the button (or event) name.

• Whenever the button is clicked, the system checks if a function with that name exists.

• If it does, the function is executed automatically.

🔄 It’s the fastest way to connect a button to an action.

🧩 Auxiliary Function

This one is for technical users who prefer modular logic.

Auxiliary functions are not directly linked to a button, but rather to other functions or actions. They are useful for:

• Executing repetitive tasks

• Saving memory

• Making updates easier

🧪 Example:

You want to change the color of 50 different objects using separate buttons. Instead of repeating the same block of actions 50 times, you can:

1. Create an auxiliary function containing the color change logic.

2. In each button, use the Active Function action to call the auxiliary function.

Result: if you want to change the behavior later, you only need to edit the auxiliary function — much simpler and more efficient.

🧠 Summary:

Function Type	Linked to Button/Events?	Ideal For
Associative Function	✅ Yes	Simple and direct actions
Auxiliary Function	❌ No	Complex and reusable logic
