Description

Default built-in brush for painting or erasing tiles and/or gamobjects on a grid.

Default brush is meant for two things: Authoring GameObjects on a grid and authoring tiles on a grid. It can be used for both at the same time if necessary. Basically the default brush allows you to pick and paste tiles and GameObjects from one area to another.

Tiles in a tilemap are considered to be active for brush editing if a GameObject with Tilemap is currently selected. GameObjects are considered to be active for brush editing if their parent GameObject is currently selected.

For example: A new default brush with size of 2x3 is generated as a result of Scene view picking operation. The new instance contains six cells (BrushCell) and the cells are fed with tiles & GameObjects from the picking area.

Later when this brush is used in a painting operation, all the tiles and GameObjects contained in the cells are set/cloned into a new Scene position.

When creating custom brushes, it is recommended to inherit GridBrushBase by default. Inheriting GridBrush is possible when similar functionality is required, but extending it has its limits compared to base class.

It is also possible to replace the default GridBrush from the Tile Palette brush list completely by using the GridDefaultBrush attribute on one of your custom brushes and promote it to become a new default brush of the project. This is useful when higher level brush can operate as a default and protect designers from accidentally using the built-in one.

FlipFlips the brush in the given axis.
FloodFillFlood fills tiles and GameObjects starting from a given position within the selected layers.
GetCellIndexGets the index to the GridBrush.BrushCell based on the position of the BrushCell.
GetCellIndexWrapAroundGets the index to the GridBrush.BrushCell based on the position of the BrushCell. Wraps each coordinate if it is larger than the size of the GridBrush.

ResetClear all data of the brush.
RotateRotates the brush by 90 degrees in the given direction.
SetColorSets a tint color at the position in the brush.
SetMatrixSets a transform matrix at the position in the brush. This matrix is used specifically for tiles on a Tilemap and not GameObjects of the brush cell.
