# Blocks
|
|
|
|
Blocks are Nodes that define the behavior of a [Context](Contexts.md). You can create and reorder Blocks within a Context and, when Unity plays a visual effect, Blocks execute from top to bottom.
|
|
|
|
|
|
|
|
You can use Blocks for many purposes, from simple value storage (for example, a random Color) to high-level complex operations such as Noise Turbulence, Forces, or Collisions.
|
|
|
|
## Adding Blocks
|
|
|
|
To add a Block to a Context, either:
|
|
|
|
* Right click the Context and select **Create Block** from the context menu.
|
|
* With the cursor above a Context, press the spacebar.
|
|
|
|
**Note**: Unity places the Block that you create at the closest position to the cursor. Use this behavior to place Blocks in the correct position.
|
|
|
|
## Manipulating Blocks
|
|
|
|
Blocks are essentially Nodes that have a different workflow logic. Blocks are always stacked within a container, called a [Context](Contexts.md) and their workflow logic connects vertically without visible links.
|
|
|
|
* To move a Block, click the Block's header and drag it to another compatible Context.
|
|
|
|
* To reorder a Block, click click the Block's header and drag it to a different position in the same Context.
|
|
|
|
* You can also cut, copy, paste, and duplicate Blocks. To do this:
|
|
* Right click on the Bode and select the command from the context menu.
|
|
* Select the Block and use the following Keyboard shortcuts:
|
|
* On Windows
|
|
* **Copy**: Ctrl+C.
|
|
* **Cut**: Ctrl+X.
|
|
* **Paste**: Ctrl+V.
|
|
* **Duplicate**: Ctrl+D.
|
|
* On OSX
|
|
* **Copy**: Cmd+C.
|
|
* **Cut**: Cmd+X.
|
|
* **Paste**: Cmd+V.
|
|
* **Duplicate**: Cmd+D.
|
|
|
|
* To disable a Block, disable the checkbox to the right of the Block's header. This requires you to recompile the graph.
|
|
|
|
## Configuring Blocks
|
|
|
|
To change the way that the Block looks and behaves, adjust the Block's [Settings](GraphLogicAndPhilosophy.md#settings) in the Node UI or the Inspector.
|
|
|
|
For example, if, in the Inspector, you change the Composition Settings of a **Set Velocity** Block from **Overwrite** to **Blend**, this changes the title of the Node to **Blend Velocity** and adds a **Blend** property to the Node UI.
