Method Details

generateRandomDirection

public static BlockPos generateRandomDirection(RandomSource pRandom,
 int pHorizontalDistance,
 int pVerticalDistance)

Gets a random position within a certain distance.

generateRandomDirectionWithinRadians

@Nullable
public static BlockPos generateRandomDirectionWithinRadians(RandomSource pRandom,
 int pMaxHorizontalDifference,
 int pYRange,
 int pY,
 double pX,
 double pZ,
 double pMaxAngleDelta)

Parameters:

pMaxHorizontalDifference - The maximum value in x and z, in absolute value , that could be returned.

pYRange - The range plus or minus the y position to be chosen

pY - The target y position

pX - The x offset to the target position

pZ - The z offset to the target position

pMaxAngleDelta - The maximum variance of the returned angle, from the base angle being a vector from (0, 0) to (x, z).

Returns:

a random (x, y, z) coordinate by picking a point (x, z), adding a random angle, up to a difference of maxAngleDelta. The y position is randomly chosen from the range [y - yRange, y + yRange]. Will be null if the chosen coordinate is outside a distance of maxHorizontalDistance from the origin.

moveUpOutOfSolid

public static BlockPos moveUpOutOfSolid(BlockPos pPos,
 int pMaxY,
 Predicate<BlockPos> pPosPredicate)

Returns:

the highest above position that is within the provided conditions

moveUpToAboveSolid

public static BlockPos moveUpToAboveSolid(BlockPos pPos,
 int pAboveSolidAmount,
 int pMaxY,
 Predicate<BlockPos> pPosPredicate)

Finds a position above based on the conditions. After it finds the position once, it will continue to move up until aboveSolidAmount is reached or the position is no longer valid

generateRandomPos

@Nullable
public static Vec3 generateRandomPos(PathfinderMob pMob,
 Supplier<BlockPos> pPosSupplier)

generateRandomPos

@Nullable
public static Vec3 generateRandomPos(Supplier<BlockPos> pPosSupplier,
 ToDoubleFunction<BlockPos> pToDoubleFunction)

Tries 10 times to maximize the return value of the position to double function based on the supplied position

generateRandomPosTowardDirection

public static BlockPos generateRandomPosTowardDirection(PathfinderMob pMob,
 int pRange,
 RandomSource pRandom,
 BlockPos pPos)

Returns:

a random position within range, only if the mob is currently restricted
