Randomizes the indexes of a rectangular region of tiles (in tile coordinates) within the specified layer. Each tile will receive a new index. New indexes are drawn from the given weightedIndexes array. An example weighted array:
[ { index: 6, weight: 4 }, // Probability of index 6 is 4 / 8 { index: 7, weight: 2 }, // Probability of index 7 would be 2 / 8 { index: 8, weight: 1.5 }, // Probability of index 8 would be 1.5 / 8 { index: 26, weight: 0.5 } // Probability of index 27 would be 0.5 / 8 ]
The probability of any index being choose is (the index's weight) / (sum of all weights). This method only modifies tile indexes and does not change collision information.

|---|---|---|---|
| weightedIndexes | Array.<object> |
An array of objects to randomly draw from during randomization. They should be in the form: { index: 0, weight: 4 } or { index: [0, 1], weight: 4 } if you wish to draw from multiple tile indexes. |
