# Integration : Update Position
|
||
|
|
|
||
|
|
Menu Path : **Implicit > Integration : Update Position**
|
||
|
|
|
||
|
|
The **Integration : Update Position** Block updates particle positions based on their velocity. If the system uses the velocity attribute and you enable **Update Position** in the Update Context's Inspector, Unity implicitly adds this Block to the Context and hides it.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
This Block adds the particle velocity multiplied by deltaTime to the current particle position:
|
||
|
|
|
||
|
|
`position += velocity * deltaTime;`
|
||
|
|
|
||
|
|
If you disable **Update Position** in the Update Context's Inspector, the system does not change the particle **position** based on the particle's velocity attribute.
|
||
|
|
|
||
|
|
You can also add the **Integration : Update Position** Block to the Update Context manually and enable/disable it to specify when the System updates the particle position based on its velocity.
