intersectIgnoringLiquids

@Nullable
public static net.minecraft.util.BlockHitResult intersectIgnoringLiquids(net.minecraft.world.World world,
                                                                                   net.minecraft.util.math.BlockPos position,
                                                                                   net.minecraft.util.math.Vec3d start,
                                                                                   net.minecraft.util.math.Vec3d end)

Standard callback for raytrace(World, Vec3d, Vec3d, CollisionDetector), only checks blocks that have a bounding box and are not liquids.

Parameters:

world - the world to perform the intersection check in.

position - the 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

@Nullable
public static net.minecraft.util.BlockHitResult intersectIgnoringTransparent(net.minecraft.world.World world,
                                                                                       net.minecraft.util.math.BlockPos position,
                                                                                       net.minecraft.util.math.Vec3d start,
                                                                                       net.minecraft.util.math.Vec3d end)

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

Parameters:

world - the world to perform the intersection check in.

position - the 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.

raytrace

@Nullable
public static net.minecraft.util.HitResult raytrace(net.minecraft.world.World world,
                                                              net.minecraft.util.math.Vec3d start,
                                                              net.minecraft.util.math.Vec3d end)

Trace along the specified line, testing for collision with blocks along the way.

Uses the default intersection logic defined in intersectIgnoringLiquids(World, BlockPos, Vec3d, Vec3d).

Parameters:

world - the world to shoot the ray in.

start - the start of the line to trace.

end - the end of the line to trace.

Returns:

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

raytrace

@Nullable
public static net.minecraft.util.HitResult raytrace(net.minecraft.world.World world,
                                                              net.minecraft.util.math.Vec3d start,
                                                              net.minecraft.util.math.Vec3d end,
                                                              Raytracing.CollisionDetector callback)

Trace along the specified line, testing for collision with blocks along the way.

Parameters:

world - the world to shoot the ray in.

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.
