Tidy Tile Mapper‎ > ‎Runtime API‎ > ‎BlockUtilities‎ > ‎


Refreshes the target BlockMap, optionally randomising the variations of the Block within.

This is a useful function when procedurally generating large levels.

If we utilize the AddBlockToMap function without refreshing upon addition, and only refresh at the end of our generation using this function, we will save valuable, delicious time.


void RefreshMap(BlockMap map, bool randomise)

Return value Description
void Sweet, emptiness.

Argument DataType Description
map BlockMap The BlockMap that you wish to refresh.
randomise bool Do you wish to randomise the variants on the Blocks within the BlockMap as you refresh the map? Useful for making nice, organic maps when procedurally-generating levels.
