Phase 2: Creating a Smart Enemy

Objective: Create an Enemy that can detect the Player when it is behind them and fire a laser.

Smart Enemy in Action

The first thing I will do is create a copy of the Enemy and rename it Enemy_Smart. The next thing is to create a new script and inherent the Enemy script so I can reuse its code.

I will use RayCasthit2D to detect the Player. So I will need a radius and distance variable. Also I will set up a bool to determine if the enemy can fire.

The RayCasthit2D is setup as follows:

When the Player is detected, I will call the FireLaserUp Method

This Method will set the can fire to false and instantiate the laser. It also calls a method in the laser script and starts the cool down.

Now that the Smart Enemy script is all set, I will move to the Laser script.

I added a Method to set the Laser to a SmartLaser. This Method is called when the Laser is instantiated.

Also in the Laser script, I updated the OnTriggerEnter2D Method to detect the SmartLaser.

Let’s see this on action.

Happy Coding!!!
