## Description

Changes the center of mass of an object smoothly during the given time (in seconds). A time of zero (or using the alternative syntax) means an immediate change.

## Syntax

### Syntax 1

```sqf
myObject setCenterOfMass [centerOfMass, time]
```

**Parameters:**

- `myObject`: [Object](../topics/Object.md)
- `centerOfMass`: [PositionRelative](../topics/Position.md#positionrelative) - relative to the model centre
- `time`: [Number](../topics/Number.md) - transition time, 0 for instant center of mass transfer

**Returns:** [Nothing](../topics/Nothing.md)

### Syntax 2

```sqf
myObject setCenterOfMass centerOfMass
```

**Parameters:**

- `myObject`: [Object](../topics/Object.md)
- `centerOfMass`: [PositionRelative](../topics/Position.md#positionrelative) - relative to the model centre

**Returns:** [Nothing](../topics/Nothing.md)

## Examples

### Example 1

```sqf
myObject setCenterOfMass [[0,-1,0], 0.5];
```

### Example 2

```sqf
myObject setCenterOfMass [0,-1,0];
```
