/**
|
|
* Sets collision on the given tile or tiles within a layer by index. You can pass in either a
|
|
* single numeric index or an array of indexes: [2, 3, 15, 20]. The `collides` parameter controls if
|
|
* collision will be enabled (true) or disabled (false).

* @private

* @since 3.0.0
|
|
*
|
|
* @param {(integer|array)} indexes - Either a single tile index, or an array of tile indexes.
|
|
* @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 - If true, updates the current tiles on the layer. Set to
|
|
* false if no tiles have been placed for significant performance boost.
