Integration : Update Position

Menu Path : Implicit > Integration : Update Position

The Integration : Update Position Block updates particle positions based on their velocity.

Note: 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. If you add your own Integration : Update Position Block too, Unity updates positions twice.

Unity adds a Update Position Block when you enable Update Position in the Update Context's Inspector.

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.

Manually adding the Update Position Block lets you manually enable or disable it.
