Functions

move (direction, moveDelay, movePlayer)

Tries to move the block to a specified direction. Move delay and the option to move the player can be passed, too.

Parameters:

direction string The direction to move the block to.
moveDelay number The delay of how long it takes to the block to be able to be moved again. By default 100 (ms).
movePlayer boolean Is the player also moved? By default false.

Returns:

boolean

Usage:

```
block.move("right")
```
```
block.move("right", 200, true)
```

teleportto (xpos, ypos, removecurrentblock, removetargetspot)

Teleports the block to the given relative position. NOTE: This is only client-side, meaning this function will only work on the person's client who touched the block.

Parameters:

xpos int The amount to move the block among the x-axis.
ypos int The amount to move the block among the y-axis.
removecurrentblock boolean If the original block should be deleted upon a successful teleportation. True by default.
removetargetspot boolean If true, the teleporting block teleports to its specified location and deletes the block if its spot is taken up. False by default.

Returns:

boolean

Usage:

block.teleportto(0, -7, false, true)

teleporttopos (xpos, ypos, removecurrentblock, removetargetspot)

Teleports the block to the given absolute position. NOTE: This is only client-side, meaning this function will only work on the person's client who touched the block.

Parameters:

xpos int The x-position to teleport the block to.
ypos int The y-position to teleport the block to.
removecurrentblock boolean If the original block should be deleted upon a successful teleportation. True by default.
removetargetspot boolean If true, the teleporting block teleports to its specified location and deletes the block if its spot is taken up. False by default.

Returns:

boolean

Usage:

block.teleporttopos(0, -7, false, true)

bulkteleportto (removecurrentblock, removetargetspot, ...)

Teleports the block to multiple positions. NOTE: This is only client-side, meaning this function will only work on the person's client who touched the block.

This is equivalent to calling block.teleportto() multiple times, but in a cleaner and more performant way.

Parameters:

removecurrentblock boolean If the original block should be deleted upon a successful teleportation. True by default.
removetargetspot boolean If true, the teleporting block teleports to its specified location and deletes the block if its spot is taken up. False by default.
... vararg You may pass any number of pairs of xpos and ypos, or you may instead (or additionally) pass a call to tovararg() as the final argument.

Returns:

array

Usage:

block.bulkteleportto(false, true, 0, -7, 0, -8, 1, -8, 0, -8)

block.bulkteleportto(false, true, tovararg({{x = 0, y = -7}, {x = 0, y = -8}, {x = 1, y = -8}, {x = 1, y = -7}}))

vanish (time, vanishduration)

Makes the block vanish and reappear later. The vanish delay can be passed.

Parameters:

time int The amount of time until vanishing. Vanishes instantly by default.
vanishduration int The amount of time it takes for the block to reappear after being vanished. 2000 by default.

explode (damage, vel, recovery)

Makes the block explode, damaging the player in the process.

Parameters:

damage int The amount of damage done to the player. By default 1.
vel number The strength of the impact that pushes the player. By default 0.3.
recovery number The number of seconds the player takes to recover. By default 2.5.

Usage:

block.explode(3, 1.1)

hurtplayer (damage, vel, recovery, checkRecovery)

Makes the block hurt the player by a specific amount and with a specified velocity.

Parameters:

damage int The amount of damage done to the player. By default 1.
vel number The strength of the impact that pushes the player. By default 0.3.
recovery number The number of seconds the player takes to recover. By default 2.5.
checkRecovery boolean Prevents pushing the player if they have invulnerability received by recovering from damage. By default true.

Usage:

block.hurtplayer(3, 1.1)

crumble (particles, damageModifier, damageThreshold)

Calculates crumble damage to the block depending on the player's velocity. Causes the block's health to drop and shatters the block if it goes to zero or below.

Parameters:

particles boolean Whatever to show particles when damage. By default true.
damageModifier number Modifier used to calculate the velocity to damage. By default 100.
damageThreshold number The threshold for how high the damage has to be to damage this block. By default 7.

strength number The strength of the player pulling/pushing effect of the black hole. By default 1.
offsetx int How many blocks away to the right does the black hole spawn? By default 0.
offsety int How many blocks away downwards does the black hole spawn? By default 0.
speedx int How fast does the black hole move to right? By default 0.
speedy int How fast does the black hole move downwards? By default 0.

Usage:

block.blackhole(9900, 1, 0, 0, 0, 0)

getblock (x, y, keepPlayerReference)

Finds another block by given coordinates. A player reference can be passed.

Parameters:

x int How many blocks to the right the wanted block is?
y int How many blocks downwards the wanted block is?
keepPlayerReference boolean Is the player reference kept? By default false.

setmetadata (key, value)

Sets a metadata with a specified key-value pair to the block.

getmetadata (key, defaultValue)

Gets a block metadata value with the specified key.

Parameters:

defaultValue The value to return if the searched key does not exists. By default no specific value is returned.

Returns:

Returns the key's value. Returns defaultValue instead if the key isn't found.

Usage:

```
block.getmetadata("coins", 0)
```

block.getmetadata("block name", "unnamed")

Fields

health

Current health of the block. The block is shattered if its health goes to zero or below.

paused

Is the block paused? Paused blocks can't move or change into different blocks.

canmove

Can the block be moved

xpos

The absolute x-position of the block.

ypos

The absolute y-position of the block.

onBreak

The event handler for block break. This event may be cancelled to prevent the block from breaking.

Provides the broken block, the side from which it was broken, and the reason; the reason may be either a Projectile, a Player (which may also be a LocalPlayer), or nil

Usage:

game.level.getBlockAt(5, 7).onBreak.addListener(function(event)
    event.cancelled = true --Prevents the block from breaking

    local block = tolua(event.block)
    local side = tolua(event.side)
    local reason = tolua(event.reason)

    if tolua(instanceof(reason, Projectile)) then --Checks if an item was used to break the block
        local shooter = tolua(reason.shooter)
        if tolua(instanceof(shooter, LocalPlayer)) then --Checks if the shooter is the local player
            shooter.hurt()
