# orient_to_velocity

Orient the particle by setting its axisY to the velocity’s current direction.

## Declaration

```swift
void orient_to_velocity()
```

## Discussion

Discussion Adding this node will cause a float3 axisY attribute to be added, if one doesn’t already exist. note:  note: Reads from element state float3 velocity, if it exists note: Writes to element state float3 axisY
