GridBrushBase

All brushes added must inherit from GridBrushBase. GridBrushBase provides a fixed set of APIs for painting.

public virtual void Paint(GridLayout grid, GameObject brushTarget, Vector3Int position)

Paint adds data onto the target GameObject brushTarget with the GridLayout grid at the given position. This is triggered when the Brush is activated on the grid and the Paint Tool is selected on the Palette window. Override this to implement the action desired on painting.

public virtual void Erase(GridLayout grid, GameObject brushTarget, Vector3Int position)

Erase removes data onto the target GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
See in Glossary brushTarget with the GridLayout grid at the given position. This is triggered when the Brush is activated on the grid and the Erase Tool is selected on the Palette window. Override this to implement the action desired on erasing.

public virtual void BoxFill(GridLayout grid, GameObject brushTarget, BoundsInt position)

BoxFill adds data onto the target GameObject brushTarget with the GridLayout grid onto the given bounds. This is triggered when the Brush is activated on the grid and the Box Fill Tool is selected on the Palette window. Override this to implement the action desired on filling.

public virtual void FloodFill(GridLayout grid, GameObject brushTarget, Vector3Int position)

FloodFill adds data onto the target GameObject brushTarget with the GridLayout grid starting at the given position and filling all other possible areas linked to the position. This is triggered when the Brush is activated on the grid and the Flood Fill Tool is selected on the Palette window. Override this to implement the action desired on filling.

public virtual void Rotate(RotationDirection direction)

Rotate rotates the content in the brush with the given direction based on the currently set pivot.

public virtual void Flip(FlipAxis flip)

Flip flips the content of the brush with the given axis based on the currently set pivot.

public virtual void Select(GridLayout grid, GameObject brushTarget, BoundsInt position)

Select marks a boundary on the target GameObject brushTarget with the GridLayout grid from the given bounds. This allows you to view information based on the selected boundary and move the selection with the Move Tool. This is triggered when the Brush is activated on the grid and the Select tool is selected on the Palette window. Override this to implement the action desired when selecting from a target.

public virtual void Pick(GridLayout grid, GameObject brushTarget, BoundsInt position, Vector3Int pivot)

Pick pulls data from the target GameObject brushTarget with the GridLayout grid from the given bounds and pivot position, and fills the brush with that data. This is triggered when the Brush is activated on the grid and the Pick Tool is selected on the Palette window. Override this to implement the action desired when picking from a target.

public virtual void Move(GridLayout grid, GameObject brushTarget, BoundsInt from, BoundsInt to)

Move marks the movement from the target GameObject brushTarget with the GridLayout grid from the given starting position to the given ending position. Override this to implement the action desired when moving from a target. This is triggered when the Brush is activated on the grid and the Move Tool is selected on the Palette window and the Move is performed (MouseDrag). Generally, this would be any behaviour while a Move operation from the brush is being performed.

public virtual void MoveStart(GridLayout grid, GameObject brushTarget, BoundsInt position)

MoveStart marks the start of a move from the target GameObject brushTarget with the GridLayout grid from the given bounds. This is triggered when the Brush is activated on the grid and the Move Tool is selected on the Palette window and the Move is first triggered (MouseDown). Override this to implement the action desired when starting a move from a target. Generally, this would be picking of data from the target with the given start position.

public virtual void MoveEnd(GridLayout grid, GameObject brushTarget, BoundsInt position)

MoveEnd marks the end of a move from the target GameObject brushTarget with the GridLayout grid from the given bounds. This is triggered when the Brush is activated on the grid and the Move Tool is selected on the Palette window and the Move is completed (MouseUp). Override this to implement the action desired when ending a move from a target. Generally, this would be painting of data to the target with the given end position.
