Member Function Documentation

blitBackAll()

void MMVManip::blitBackAll	(	std::map< v3s16, MapBlock * > *	modified_blocks,
		bool	overwrite_generated = true ) const

Writes data in VManip back to the map.

Blocks without any data in the VManip are skipped.

Note

VOXELFLAG_NO_DATA is checked per-block, not per-node. So you need to ensure that the relevant parts of m_data are initialized.

Parameters

modified_blocks	output array of touched blocks (optional)
overwrite_generated	if false, blocks marked as generate in the map are not changed

getCoveredBlocks()

)

const

Uses the flags array to determine which blocks the VManip covers, and for which of them we have any data.

Warning

requires VManip area to be block-aligned

Returns

map of blockpos -> any data?
