This Brush instances and places randomly selected Prefabs onto the target location and parents the instanced object to the paint target. Use this Brush as an example to create custom Brushes which can quickly place an assortment of GameObjects onto structured locations.

Properties

Property	Function
Perlin Scale	The factor using the Perlin noise algorithm for the random distribution of Prefabs chosen when painting.
Prefabs	Set the number of and selection of Prefabs to paint from.
	Size	Set the number of Prefabs that the Brush selects from.
	Element *	Set one of the Prefabs to select from for each entry. The number of Element entries matches the value set in Size.

Usage

First set the number of Prefabs to select from in the Prefabs property, then add Prefab Assets to the list. Adjust the Perlin Scale property to adjust the distribution of Prefabs painted onto a particular cell.

When painting with the Prefab Brush, the Prefab Brush picks from the available Prefabs based on the Perlin Scale set, and instantiate the Prefabs to the Scene.

Implementation

The Prefab Brush inherits from the Grid Brush and implements the following overrides:

• It overrides the Paint method to paint a Prefab from the Prefab selection.
• It overrides the Erase method to be able to erase the instantiated Prefabs or other GameObjects from the Scene.
