virtual bool CanExplode (int i, int j)
 Whether or not the tile/wall at the given coordinates can be killed by an explosion (ie. bombs). Returns true by default; return false to stop an explosion from destroying it. More...
 
virtual bool CanPlace (int i, int j)
 Allows you to stop this tile/wall from being placed at the given coordinates. This method is called on the local client. For tiles this is also checked during block replacement, but ModTile.CanReplace(int, int, int) should be used for replace-specific logic. Return false to stop the tile/wall from being placed. Returns true by default. More...
 
virtual bool CreateDust (int i, int j, ref int type)
 Allows you to modify the default type of dust created when the tile/wall at the given coordinates is hit. Return false to stop the default dust (the type parameter) from being created. Returns true by default. The type parameter defaults to DustType. More...
 
LocalizedText CreateMapEntryName ()
 Legacy helper method for creating a localization sub-key MapEntry More...
 
virtual ushort GetMapOption (int i, int j)
 Allows you to choose which minimap entry the tile/wall at the given coordinates will use. 0 is the first entry added by AddMapEntry, 1 is the second entry, etc. Returns 0 by default. More...
 
virtual bool KillSound (int i, int j, bool fail)
 Allows you to customize which sound you want to play when the tile/wall at the given coordinates is hit. Return false to stop the game from playing its default sound for the tile/wall. Returns true by default. More...
 
virtual void ModifyLight (int i, int j, ref float r, ref float g, ref float b)
 Allows you to determine how much light this tile/wall emits.
If it is a tile, make sure you set Main.tileLighted[Type] to true in SetDefaults for this to work.
If it is a wall, it can also let you light up the block in front of this wall.
See Terraria.Graphics.Light.TileLightScanner.ApplyTileLight(Tile, int, int, ref Terraria.Utilities.FastRandom, ref Microsoft.Xna.Framework.Vector3) for vanilla tile light values to use as a reference.

virtual void PostDraw (int i, int j, SpriteBatch spriteBatch)
 Allows you to draw things in front of the tile/wall at the given coordinates. This can also be used to do things such as creating dust.Note that this method will be called for tiles even when the tile is Tile.IsTileInvisible due to Echo Coating. Use the GameContent.Drawing.TileDrawing.IsVisible(Tile) method to skip effects that shouldn't show when the tile is invisible. This method won't be called for invisible walls. More...

virtual void ModBlockType.ModifyLight ( int  i,
int  j,
ref float  r,
ref float  g,
ref float  b 
)
virtual

Allows you to determine how much light this tile/wall emits.
If it is a tile, make sure you set Main.tileLighted[Type] to true in SetDefaults for this to work.
If it is a wall, it can also let you light up the block in front of this wall.
See Terraria.Graphics.Light.TileLightScanner.ApplyTileLight(Tile, int, int, ref Terraria.Utilities.FastRandom, ref Microsoft.Xna.Framework.Vector3) for vanilla tile light values to use as a reference.
