/**
|
|
* Sets collision on a range of tiles in a layer whose index is between the specified `start` and
|
|
* `stop` (inclusive). Calling this with a start value of 10 and a stop value of 14 would set
|
|
* collision for tiles 10, 11, 12, 13 and 14. The `collides` parameter controls if collision will be
|
|
* enabled (true) or disabled (false).

* @function Phaser.Tilemaps.Components.SetCollisionBetween
|
|
* @private
|
|
* @since 3.0.0
|
|
*
|
|
* @param {integer} start - The first index of the tile to be set for collision.
|
|
* @param {integer} stop - The last index of the tile to be set for collision.
|
|
* @param {boolean} [collides=true] - If true it will enable collision. If false it will clear collision.
|
|
* @param {boolean} [recalculateFaces=true] - Whether or not to recalculate the tile faces after the update.
|
|
* @param {Phaser.Tilemaps.LayerData} layer - The Tilemap Layer to act upon.
|
|
* @param {boolean} [updateLayer=true] - If true, updates the current tiles on the layer. Set to
|
|
* false if no tiles have been placed for significant performance boost.
