The Callbacks in the Trace() function is a table that contains named functions. Cuberite will call
individual functions from that table for the events that occur on the line - hitting a block, going out of
valid world data etc. The following table lists all the available callbacks. If the callback function is
not defined, Cuberite skips it. Each function can return a bool value, if it returns true, the tracing is
aborted and Trace() returns false.</p>

<table><tr><th>Name</th><th>Parameters</th><th>Notes</th></tr>
<tr><td>OnNextBlock</td><td>BlockX, BlockY, BlockZ, BlockType, BlockMeta, EntryFace</td>
	<td>Called when the ray hits a new valid block. The block type and meta is given. EntryFace is one of the
	BLOCK_FACE_ constants indicating which "side" of the block got hit by the ray.</td></tr>
<tr><td>OnNextBlockNoData</td><td>BlockX, BlockY, BlockZ, EntryFace</td>
	<td>Called when the ray hits a new block, but the block is in an unloaded chunk - no valid data is
	available. Only the coords and the entry face are given.</td></tr>
<tr><td>OnOutOfWorld</td><td>X, Y, Z</td>
	<td>Called when the ray goes outside of the world (Y-wise); the coords specify the exact exit point. Note
	that for other paths than lines (considered for future implementations) the path may leave the world and
	go back in again later, in such a case this callback is followed by OnIntoWorld() and further
	OnNextBlock() calls.</td></tr>
<tr><td>OnIntoWorld</td><td>X, Y, Z</td>
	<td>Called when the ray enters the world (Y-wise); the coords specify the exact entry point.</td></tr>
<tr><td>OnNoMoreHits</td><td>&nbsp;</td>
	<td>Called when the path is sure not to hit any more blocks. This is the final callback, no more
	callbacks are called after this function. Unlike the other callbacks, this function doesn't have a return
	value.</td></tr>
<tr><td>OnNoChunk</td><td>&nbsp;</td>
	<td>Called when the ray enters a chunk that is not loaded. This usually means that the tracing is aborted.
	Unlike the other callbacks, this function doesn't have a return value.</td></tr>
