                                                                               net.minecraft.util.Vec3 end)

Standard callback for raytrace(World, Vec3, Vec3, CollisionDetector), only checks blocks that have a bounding box and are not liquids.

Parameters:

world - the world to perform the intersection check in.

x - the x position of the block to perform the intersection check with.

y - the y position of the block to perform the intersection check with.

z - the z position of the block to perform the intersection check with.

start - the start of the line to intersect the block with.

end - the end of the line to intersect the block with.

Returns:

hit information on the intersect, or null if there was none.

intersectIgnoringTransparent

public static net.minecraft.util.MovingObjectPosition intersectIgnoringTransparent(net.minecraft.world.World world,
                                                                                   int x,

Checks only blocks that have a bounding box and are not see-through.

Parameters:

world - the world to perform the intersection check in.

x - the x position of the block to perform the intersection check with.

y - the y position of the block to perform the intersection check with.

z - the z position of the block to perform the intersection check with.

start - the start of the line to intersect the block with.

end - the end of the line to intersect the block with.

raytrace

public static net.minecraft.util.MovingObjectPosition raytrace(net.minecraft.world.World world,
                                                               net.minecraft.util.Vec3 start,

start - the start of the line to trace.

end - the end of the line to trace.

Returns:

start - the start of the line to trace.

end - the end of the line to trace.

callback - the method to call for each potential hit to perform collision logic.

Returns:

the first detected hit, or null if there was none.
