# setModeWeaponWithStartPosition(_:endPosition:resistiveStrength:)

Sets the mode to provide feedback when the user depresses the trigger between the start and the end positions.

```
func setModeWeaponWithStartPosition(_ startPosition: Float, endPosition: Float, resistiveStrength: Float)
```

## Parameters

`startPosition`

The effect’s start position. A value between `0` and `1` , where `0` is the minimum and `1` is the maximum trigger depression.

`endPosition`

The effect’s end position. A value between `0` and `1` , where `0` is the minimum and `1` is the maximum trigger depression. This value must be greater than `startPosition`.

`resistiveStrength`

The strength of the effect. A value between `0` and `1`, where `0` is the minimum or off value, and `1` is the maximum strength.

## Discussion

When the user depresses the trigger beyond the value of the end position, it stops providing feedback, giving the user a sense of release, similar to pulling a weapon trigger.
