The following are the usual methods you would override: RefreshTile determines which Tiles in the vicinity are updated when this Tile is added to the Tilemap. Override any required methods for your new Tile class. Handles.DrawLine(new Vector3(min.x, max.y, min.z), new Vector3(min.x, min.y, min. Create a new class inheriting from TileBase (or any useful sub-classes of TileBase, like Tile). Handles.DrawLine(new Vector3(max.x, max.y, min.z), new Vector3(min.x, max.y, min.z)) Handles.DrawLine(new Vector3(max.x, min.y, min.z), new Vector3(max.x, max.y, min.z)) Handles.DrawLine(new Vector3(min.x, min.y, min.z), new Vector3(max.x, min.y, min.z)) Scriptable Tiles are Tiles which you script which adapt to the position and conditions of the Tilemap it is placed and displays the relevant Sprite there. Draws a box on the picked starting position Var max = lineBrush.lineStart + position.size PaintPreview(grid, brushTarget, paintPos) PaintPreview(grid, brushTarget, position.min) įoreach (var point in LineBrush.GetPointsOnLine(startPos, endPos)) With scriptable brushes, you can create tiles that automatically adjust their appearance based on where they've been placed in the level, change the way a line is placed on the grid, and even apply interactive components for the user when the application is being used.

The OnPaintSceneGUI method is overridden to produce the preview of the line to be drawn between the first and second mouse clicks.

The Paint method for the LineBrush is overridden to allow the user to specify the start of a line with the first mouse click in Paint mode and draw the line with the second mouse click in Paint mode. Create a new class inheriting from TileBase (or any useful sub-classes of TileBase, like Tile).Override any required methods for your new Tile class. More info See in Glossary by specifying the start point and the end point. This allows you to create different Tiles that can help you save time and be more efficient when creating Tilemaps. It then displays the Sprite which meets its scripted requirements. LineBrush provides the ability to easily draw lines of Tiles onto the Tilemap A GameObject that allows you to quickly create 2D levels using tiles and a grid overlay. You can script Tiles to adapt to different criteria and conditions, such as its position on the Tilemap.
