![]() For information on the Standard Shader properties, see documentation on Material parameters. This page describes the properties and options that are additional to the Standard Shader properties. The Standard Particle Shaders have the same set of properties as the Standard Shader (or a subset of those properties, depending on the Shader).

In the Material’s Inspector A Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. For example, you could apply a Flame Material to a Fire Particle System effect. Select the Material you want to apply the shader to. These shaders provide various particle-specific features that aren’t available with the Standard Shader A program that runs on the GPU. If (!agent.pathPending & agent.remainingDistance < 0.The Unity Standard Particle Shaders are built-in shaders that enable you to render a variety of Particle System A component that simulates fluid entities such as liquids, clouds and flames by generating and animating large numbers of small 2D images in the scene.

In the Update function, the script checks how close the agent is to the destination using the remainingDistance property. As it stands, the code cycles through the points in the sequence they occur in the array but you can easily modify this, say by using Random.Range to choose an array index at random. The GotoNextPoint function sets the destination point for the agent (which also starts it moving) and then selects the new destination that will be used on the next call. More info See in Glossary to mark the points’ positions. A GameObject’s functionality is defined by the Components attached to it. More info See in Glossary using GameObjects The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. This array can be assigned from the inspector A Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. The patrol points are supplied to the script using a public array of Transforms. The simple behaviour of the robot can be implemented using the code shown below. For example, a robot would probably just visit the points in a methodical order while a human guard might try to catch the player out by using a more random pattern. ![]() The ideal sequence of patrol points will depend on the way you want the NPCs to behave. For an office building, the key points might be the individual offices and other rooms. For example, in a maze, you might place the key patrol points at junctions and corners to ensure the agent checks every corridor. You can get a more convincing patrol pattern by keeping a set of key points that are “useful” for the NPC to pass through and visiting them in some kind of sequence. The navigation system can be used to implement this behaviour but it is slightly more involved than standard pathfinding - merely using the shortest path between two points makes for a limited and predictable patrol route. Many games feature NPCs that patrol automatically around the playing area.
