Class RandomBrush

This Brush helps to place random Tiles onto a Tilemap. Use this as an example to create brushes which store specific data per brush and to make brushes which randomize behaviour.

public class RandomBrush : GridBrush

Fields

addToRandomTiles

A flag to determine if picking will add to existing RandomTileSets

Declaration
public bool addToRandomTiles
Field Value
Type Description
Boolean

pickRandomTiles

A flag to determine if picking will add new RandomTileSets

Declaration
public bool pickRandomTiles
Field Value
Type Description
Boolean

randomTileSets

An array of RandomTileSets to choose from when randomizing

Declaration
public RandomBrush.RandomTileSet[] randomTileSets
Field Value
Type Description
RandomBrush.RandomTileSet[]

randomTileSetSize

The size of a RandomTileSet

Declaration
public Vector3Int randomTileSetSize
Field Value
Type Description

Methods

Paint(GridLayout, GameObject, Vector3Int)

Paints RandomTileSets into a given position within the selected layers. The RandomBrush overrides this to provide randomized painting functionality.

Declaration
public override void Paint(GridLayout grid, GameObject brushTarget, Vector3Int position)
Parameters
Type Name Description
GridLayout grid

Grid used for layout.
GameObject brushTarget

Target of the paint operation. By default the currently selected GameObject.
Vector3Int position

The coordinates of the cell to paint data to.

Pick(GridLayout, GameObject, BoundsInt, Vector3Int)

Picks RandomTileSets given the coordinates of the cells. The RandomBrush overrides this to provide picking functionality for RandomTileSets.

Declaration
public override void Pick(GridLayout gridLayout, GameObject brushTarget, BoundsInt bounds, Vector3Int pickStart)
Parameters
Type Name Description
GridLayout gridLayout

Grid to pick data from.
GameObject brushTarget

Target of the picking operation. By default the currently selected GameObject.
BoundsInt bounds

The coordinates of the cells to paint data from.
Vector3Int pickStart

Pivot of the picking brush.
