# Block Structures

A function block consists of several elements:

1. Header
2. Sockets
3. Controls
4. Unique Name

## Header <a href="#header" id="header"></a>

Headers can be modified by double-clicking on and setting a custom name.

## Tool Tips <a href="#tool-tips" id="tool-tips"></a>

Tool-tips are shown when blocks are hovered on with mouse and display information on inner mechanics of a block.

Same rules also apply to Controls. Hovering over [Controls](#Controls) may show additional information:

## Controls <a href="#controls" id="controls"></a>

Controls are custom buttons, lists, or any kind of interactable objects that are shown inside a function block. These widgets can alter the functionality of each function block.

## Inputs Sockets <a href="#inputs-sockets" id="inputs-sockets"></a>

Data is sent to blocks through input sockets. There are usually multiple sockets in a single block.

Robust data transfer is guaranteed when sockets with same color or category are connected.

## Output Sockets <a href="#output-sockets" id="output-sockets"></a>

Results get sent away from outputs and transferred to other blocks by connecting to an input socket.
