Removes a block from the targeted BlockMap.

This is an interesting function, as it behaves as a stripped-down equivalent of using the AddBlockToMap function with a null argument.

If you wish to refresh your surrounding blocks upon addition, I recommend using the AddBlockToMap function with a null argument, otherwise - 


RemoveBlockFromMap(BlockMap map, int x, int y, int depth, bool addEmptyBlock, bool destroyImmediate)

Return value Description
void Nothing but positive sentiments.

Argument DataType Description
map BlockMap The BlockMap from which this Block will be removed.
x int The x coordinate of the Block to be removed.
y     int The y coordinate of the Block to be removed.
depth int The depth (z) coordinate of the Block to be removed.
addEmptyBlock bool Should we add an empty block to the coordinate after removing the existing block?
destroyImmediateboolShould we utilize DestroyImmediate() instead of Destroy() when destroying the existing block? Useful for Editor scripting versus runtime (event) scripting.
