static bool	ActiveAndWalkableTile (int i, int j)
static bool	AddBuriedChest (int i, int j, int contain=0, bool notNearOtherChests=false, int Style=-1, bool trySlope=false, ushort chestTileType=0)
	Attempts to place a chest and fill it with typical loot according to the style (Style ) and depth. Without any parameters, a regular, gold, or locked shadow chest will be created, depending on the depth. You can pass in an item type (contain ) and the first item in the chest will be that item. Unlike PlaceChest(int, int, ushort, bool, int), the resulting chest will be placed with the bottom right corner at the given coordinates (i , j ). In addition, if the given j coordinate isn't suitable, AddBuriedChest will search down from the given coordinate to find the first solid tile it encounters and attempt to place there. This method returns true if a chest was successfully placed, but be aware that the chest might not be exactly at the coordinates you provide. This makes further adjusting the chest contents directly difficult. A video guide can be found on the World Generation wiki page. It shows an example of running the method with the default parameters WorldGen.AddBuriedChest(x, y);. Notice how the chest style changes according to depth and how the chest is placed on the floor directly below the provided coordinates if possible. More...

	Returns true if the provided tile coordinates are within the world bounds. When dealing with random coordinates combined with addition or subtraction, there is a chance you might construct coordinates outside the bounds of the world. This will crash world generation, so it is important that you check that the coordinates are suitable before attempting to do things at those coordinates. Use this method to check if the given coordinates fall inside the world. The fluff parameter further checks that the coordinates are at least that many tiles away from the edge, which is useful for world generation actions that could affect large areas of tiles. More...

static bool	KillActuator (int i, int j)
static void	KillTile (int i, int j, bool fail=false, bool effectOnly=false, bool noItem=false)
	Attempts to destroy the tile at the provided tile coordinates.Callers can use fail , effectOnly , and noItem to dictate if the intention is to not actually kill the tile, only spawn kill tile effects, and not drop items respectively. For example, worms typically use fail: true, effectOnly: true to spawn dust indicating the worm burrowing through the ground. ModTile.KillTile(int, int, ref bool, ref bool, ref bool) and GlobalTile.KillTile(int, int, int, ref bool, ref bool, ref bool) will be called to modify those values.Note that this method will destroy a single tile and then call the tile framing code. The noItem parameter is only relevant for 1x1 tiles, not multi-tiles. The tile framing code is what triggers multi-tiles to destroy all of their remaining tiles and drop their placement item. GlobalTile.Drop(int, int, int) must be used by the caller if the intention is to prevent item drops from a multi-tile. More...

static void	OreRunner (int i, int j, double strength, int steps, ushort type)
	Similar to TileRunner(int, int, double, int, int, bool, double, double, bool, bool, int), but without many of the options. OreRunner places small splotches of the specified tile (type ) starting at the coordinates (i and j in tile coordinates). OreRunner only replaces active tiles (Tile.HasTile) that are either TileID.Sets.CanBeClearedDuringOreRunner or Main.tileMoss, making it suitable to be used even after FrameImportant tiles (Main.tileFrameImportant) exist in the world. If you have a tile that should be susceptible to being replaced when additional ores are spawned in the world, set TileID.Sets.CanBeClearedDuringOreRunner to true for that ModTile. Vanilla code only uses this method when spawning hardmode ores. This method is suitable for use in-game and in multiplayer as it both frames and syncs tile changes. More...

static int	PlaceChest (int x, int y, ushort type=21, bool notNearOtherChests=false, int style=0)
	Attempts to place a chest at the given tile coordinates. The coordinate provided (x , y ) will be the bottom left corner of the resulting chest, if the method succeeds. type is the tile type to place, and style is the tile style to place. For vanilla chests, you can count from zero starting from the left in the Tiles_21.png image after extracting the vanilla texturesto find the style you want to place. Another option is to follow the Tile IDs wiki guideto find the style. notNearOtherChests can be set to true to prevent the chest from placing if another chest exists within 25 tiles left or right and 8 tiles up or down. This method returns the chest index (the index within Main.chest) of the chest that was successfully placed or -1 if placing the chest failed. Chest placement can fail for many reasons, such as if existing tiles block the space, or if there isn't 2 suitable solid tiles directly below the intended location. See the "Try Until Success" section of the World Generation wiki guidefor an approach to using this method. See the "Placing Items in Chests" section of the World Generation wiki guidefor info on placing items in the chest. The AddBuriedChest(int, int, int, bool, int, bool, ushort) method places a chest and fills it with the default items for that chest. More...

static bool	PlaceTile (int i, int j, int Type, bool mute=false, bool forced=false, int plr=-1, int style=0)
	PlaceTile is the main way to place individual tiles while obeying anchor considerations. Most of the other PlaceX methods in the WorldGen class are called by this method. i and j are the tile coordinates. These coordinates relate to the origin of the tile, not necessarily the top left corner of the tile. Read the Basic Tile wiki guideto familiarize yourself with the concepts of Anchors and Origins. mute indicates if a sound should be made, this only applies to in-game usage as sounds are all muted during world gen. forced attempts to place the tile even if other tiles are already at the coordinates, but it is unreliable. plr does nothing except affect bathtubs. style refers to the style of the tile type provided. Styles are explained in the Basic Tile guide. PlaceTile returns a bool indicating placement success. Unfortunately, it doesn't work, don't use it. Checking the coordinates after calling PlaceTile is a good way to check if the placement was a success: if(Main.tile[x, y].type == TileID.Campfire) PlaceTile doesn't expose everything. For example, attempting to place a tile with a specific style will be ignored by many of the underlying methods. Another issue is that it is impossible to place a tile that has left and right placement orientations facing right. In these situations, you might need to manually place each tile in the multitile or use PlaceObject(int, int, int, bool, int, int, int, int) instead. WorldGen.PlaceObject requires more input. For example, placing Coral with PlaceObject means you have to manually specify the style, as the random style (TileObjectData.RandomStyleRange) choosing is a feature of PlaceTile. If called in-game, the changed tiles would need to be synced if placement is successful. See NetMessage.SendTileSquare(int, int, int, int, int, TileChangeType) for more information and examples.

AddBuriedChest()

static bool WorldGen.AddBuriedChest ( int  i, int  j, int  contain = 0, bool  notNearOtherChests = false, int  Style = -1, bool  trySlope = false, ushort  chestTileType = 0  )

static

Attempts to place a chest and fill it with typical loot according to the style (Style ) and depth. Without any parameters, a regular, gold, or locked shadow chest will be created, depending on the depth. You can pass in an item type (contain ) and the first item in the chest will be that item. Unlike PlaceChest(int, int, ushort, bool, int), the resulting chest will be placed with the bottom right corner at the given coordinates (i , j ). In addition, if the given j coordinate isn't suitable, AddBuriedChest will search down from the given coordinate to find the first solid tile it encounters and attempt to place there. This method returns true if a chest was successfully placed, but be aware that the chest might not be exactly at the coordinates you provide. This makes further adjusting the chest contents directly difficult. A video guide can be found on the World Generation wiki page. It shows an example of running the method with the default parameters WorldGen.AddBuriedChest(x, y);. Notice how the chest style changes according to depth and how the chest is placed on the floor directly below the provided coordinates if possible.

Parameters

i
j
contain
notNearOtherChests
Style
trySlope
chestTileType

Returns

Convert()

static void WorldGen.Convert ( int  i, int  j, int  conversionType, int  size = 4  )

static

Converts biome variant tiles and walls to a target biome.
Converts a 9x9 square by default, but can be adjusted with the size parameter.

For an easily-viewable usage example, refer to the code for projectile AI style 31 (used for the Clentaminator's solutions).

Parameters

i	The X coordinate of the target tile.
j	The Y coordinate of the target tile.
conversionType	The biome that you wish to convert to. See BiomeConversionID Setting this to 0 (Purity) returns affected tiles to their default states (e.g. Ebonstone, Crimstone, and Pearlstone will be converted back into normal Stone Blocks).
size	When using this method to convert tiles, a square centered on the target tile is converted into those of the target biome. This optional parameter, which defaults to 4, determines the "radius" of that square in tiles, counting outward from the central tile. Set to 0 if you only want to convert a single tile. In other cases, use this parameter wisely.

InWorld()

static bool WorldGen.InWorld ( int  x, int  y, int  fluff = 0  )

static

Returns true if the provided tile coordinates are within the world bounds. When dealing with random coordinates combined with addition or subtraction, there is a chance you might construct coordinates outside the bounds of the world. This will crash world generation, so it is important that you check that the coordinates are suitable before attempting to do things at those coordinates. Use this method to check if the given coordinates fall inside the world. The fluff parameter further checks that the coordinates are at least that many tiles away from the edge, which is useful for world generation actions that could affect large areas of tiles.

Parameters

x
y
fluff

Returns

KillTile()

static void WorldGen.KillTile ( int  i, int  j, bool  fail = false, bool  effectOnly = false, bool  noItem = false  )

static

Attempts to destroy the tile at the provided tile coordinates.Callers can use fail , effectOnly , and noItem to dictate if the intention is to not actually kill the tile, only spawn kill tile effects, and not drop items respectively. For example, worms typically use fail: true, effectOnly: true to spawn dust indicating the worm burrowing through the ground. ModTile.KillTile(int, int, ref bool, ref bool, ref bool) and GlobalTile.KillTile(int, int, int, ref bool, ref bool, ref bool) will be called to modify those values.Note that this method will destroy a single tile and then call the tile framing code. The noItem parameter is only relevant for 1x1 tiles, not multi-tiles. The tile framing code is what triggers multi-tiles to destroy all of their remaining tiles and drop their placement item. GlobalTile.Drop(int, int, int) must be used by the caller if the intention is to prevent item drops from a multi-tile.

Parameters

i
j
fail	Prevents the tile from being destroyed, but still plays a hit sound
effectOnly	Prevents the tile from being destroyed but still spawns hit dust and prevents the hit sound.
noItem	Prevents the item from dropping. Only relevant for 1x1 tiles.

OreRunner()

static void WorldGen.OreRunner ( int  i, int  j, double  strength, int  steps, ushort  type  )

static

Similar to TileRunner(int, int, double, int, int, bool, double, double, bool, bool, int), but without many of the options. OreRunner places small splotches of the specified tile (type ) starting at the coordinates (i and j in tile coordinates). OreRunner only replaces active tiles (Tile.HasTile) that are either TileID.Sets.CanBeClearedDuringOreRunner or Main.tileMoss, making it suitable to be used even after FrameImportant tiles (Main.tileFrameImportant) exist in the world. If you have a tile that should be susceptible to being replaced when additional ores are spawned in the world, set TileID.Sets.CanBeClearedDuringOreRunner to true for that ModTile. Vanilla code only uses this method when spawning hardmode ores. This method is suitable for use in-game and in multiplayer as it both frames and syncs tile changes.

Parameters

i
j
strength
steps
type

PlaceChest()

static int WorldGen.PlaceChest ( int  x, int  y, ushort  type = 21, bool  notNearOtherChests = false, int  style = 0  )

static

Attempts to place a chest at the given tile coordinates. The coordinate provided (x , y ) will be the bottom left corner of the resulting chest, if the method succeeds. type is the tile type to place, and style is the tile style to place. For vanilla chests, you can count from zero starting from the left in the Tiles_21.png image after extracting the vanilla texturesto find the style you want to place. Another option is to follow the Tile IDs wiki guideto find the style. notNearOtherChests can be set to true to prevent the chest from placing if another chest exists within 25 tiles left or right and 8 tiles up or down. This method returns the chest index (the index within Main.chest) of the chest that was successfully placed or -1 if placing the chest failed. Chest placement can fail for many reasons, such as if existing tiles block the space, or if there isn't 2 suitable solid tiles directly below the intended location. See the "Try Until Success" section of the World Generation wiki guidefor an approach to using this method. See the "Placing Items in Chests" section of the World Generation wiki guidefor info on placing items in the chest. The AddBuriedChest(int, int, int, bool, int, bool, ushort) method places a chest and fills it with the default items for that chest.

Parameters

x
y
type
notNearOtherChests
style

Returns

PlaceSmallPile()

static bool WorldGen.PlaceSmallPile ( int  i, int  j, int  X, int  Y, ushort  type = 185  )

static

Places TileID.SmallPiles tiles. This tile is special and doesn't follow the normal style rules and won't place with PlaceTile. i and j are the coordinates. X and Y are the count and row indexes of the specific tile in the texture file. Indexes count from left to right and start at 0. So for example the Sapphire Stash would have Y=1 (second row) and X=21 (22nd 2x1 tile).

Parameters

i
j
X
Y
type

Returns

PlaceTile()

static bool WorldGen.PlaceTile ( int  i, int  j, int  Type, bool  mute = false, bool  forced = false, int  plr = -1, int  style = 0  )

static

PlaceTile is the main way to place individual tiles while obeying anchor considerations. Most of the other PlaceX methods in the WorldGen class are called by this method. i and j are the tile coordinates. These coordinates relate to the origin of the tile, not necessarily the top left corner of the tile. Read the Basic Tile wiki guideto familiarize yourself with the concepts of Anchors and Origins. mute indicates if a sound should be made, this only applies to in-game usage as sounds are all muted during world gen. forced attempts to place the tile even if other tiles are already at the coordinates, but it is unreliable. plr does nothing except affect bathtubs. style refers to the style of the tile type provided. Styles are explained in the Basic Tile guide. PlaceTile returns a bool indicating placement success. Unfortunately, it doesn't work, don't use it. Checking the coordinates after calling PlaceTile is a good way to check if the placement was a success: if(Main.tile[x, y].type == TileID.Campfire) PlaceTile doesn't expose everything. For example, attempting to place a tile with a specific style will be ignored by many of the underlying methods. Another issue is that it is impossible to place a tile that has left and right placement orientations facing right. In these situations, you might need to manually place each tile in the multitile or use PlaceObject(int, int, int, bool, int, int, int, int) instead. WorldGen.PlaceObject requires more input. For example, placing Coral with PlaceObject means you have to manually specify the style, as the random style (TileObjectData.RandomStyleRange) choosing is a feature of PlaceTile. If called in-game, the changed tiles would need to be synced if placement is successful. See NetMessage.SendTileSquare(int, int, int, int, int, TileChangeType) for more information and examples.

Parameters

i
j
Type
mute
forced
plr
style

Returns

RandomWorldPoint()

static Point WorldGen.RandomWorldPoint ( int  top = 0, int  right = 0, int  bottom = 0, int  left = 0  )

static

Generates a random tile coordinate within the world bounds. The optional parameters define additional padding, avoiding the edges or defining a target area. Point point = WorldGen.RandomWorldPoint((int)Main.worldSurface, 40, 500, 60) is equivalent to

int x = WorldGen.genRand.Next(60, Main.maxTilesX - 40); int y = WorldGen.genRand.Next((int)Main.worldSurface, Main.maxTilesY - 500);

Parameters

top
right
bottom
left

Returns
