As you might recall, Unity provides us an AI pathfinder that allows our game objects to move towards a direction while avoiding obstacles.
Attacking and Stunning Enemy
To be able to create an AI movement for our enemy, we need to add the Nav Mesh Agent component to our Knight game object. Under the bake tab, just hit bake to create the NavMesh. At this point, the next thing we need to do is create the script that allows the enemy to chase us. An important thing that we have to do to make sure that the code works is that we have to add the Player tag to our character to make sure that we grab the GameObject.
Right now the Knight would run in circle around us. But how do we get it to do an attack animation? The first thing we need to do is attach a capsule collider component onto our knight game object and made these settings:. The logic for this is similar to what we seen in the Survival Shooter. So now the Knight will start the attack animation. You might notice that nothing happens to the player. Currently, we have a Capsule Collider that will allow us to detect when the enemy is within striking range.
The next thing we need to do is figure out if the enemy touches the player. Unlike the previous collider which is a trigger, this one will actually be to detect when the enemy collides with the player. Make sure that we attach the body mesh that our Knight uses to our Mesh Collider. Before we move on to writing the code for when the Knight attacks the player, we have to add an event in the player animation.
We want to edit our Attack1 animation clip from the Brute Warrior Mecanim pack.Concrete hatch autocad
While selecting our Knight Animator Controllerclick on Attack1 in the Animator and the select the Animation tab to open it. According to this helpful postwe should just duplicate the animation clip.
To do this, I dragged out the Animation tab and docked it pretty much anywhere else in the window, like so:. Select our Knight object in the game hierarchy and then you can notice that back in the animation tab, the play button is clickable now. Playing the animation, I believe that triggering our event at frame 16 would be the best point to see if we should damage the player.
Drag that event to frame From under the Inspector we can select a function from the scripts attached to play.
Play the game and look at the console for the logs to see when the knight gets within attacking zone, when he bumps into the player, and when he successfully hits the player. Initially, I thought it would be simply applying the Nav Mesh Agent like we did in the Survivor Shooter game, however, when I started thinking about attack animations, things became more complicated and I spent a lot of time trying to figure out how to damage the player ONLY during the attack animation.
Game Development Stack Exchange is a question and answer site for professional and independent game developers. It only takes a minute to sign up. When my character swings their sword, every enemy within a radius takes damage. I want to make sure that melee attacks only damage enemies the player is facing. Compare the direction your character is facing with the direction to the enemy. The dot product of vector A and vector B divided by the magnitude of vector B will tell you the projection of A onto B.
If you're using normalized vectors, you can skip the division. The results can be interpreted as follows:. Decide if you want the sword slash to be single target or hit all enemies in a cone in the direction you are facing. More details: A melee attack is simply in game mechanics terms a ranged attack with a short range. There are generally two kinds of attacks, a single target attack where you only damage one enemy at most and AoE where you damage multiple foes every character within the range of the area of effect.
In your case, I think you headed in the right direction. Checking the distance.Revelation 20 1 3
Now you need to check the angle between your character and that enemy and compare it to the angle you are facing. Clearly, distance from the player is not the only important factor. There's also the enemies' direction. If you know the position vector of the player p and that of the enemy eyou can observe by a basic trigonometric identity that.
You then filter down the list of enemies, first by whether they're in the radius, then further by whether the angle to them is within the angle of the attack. Everything left gets hit. There are many ways to achieve this.
Here's one way, which should be easy to make work with your existing code.Unity AI Tutorial : Enemy Attack
Create a Transform and make it a child of your player character. Position it where the attack lands and then add it as a public Transform of the PlayerAttack script. Let's call it attackPositionTransform.
Now in your MeleeAttack function, you can compare the position of the attackPositionTransform with the target. Just make a circle collider to check when an object enters your attack radius, then use foreach to access all the objects near you:. Now you have a list with everthing close to you, and you can just use the dot product to check back stabs, and add a effect like stun.
To do the damage, you can just make a box collider, and size it to your needs. This will be the hit area. If the collider intersects with one of all damage candidates, fire your damage method.You must register to post or download hacks. Follow MPGH. Remember Me? Game Development.

You need to factor in being on a higher ground than the enemy or lower. I might release some paid unity assets soon. Gratz on learning from tutorials but if your going to release some code make tweak it up at abit. Like your Health script which is word for word from this tut 2.

Yup, I've got a problem with another script The script is meant to make a computer bug move forward and attack the player once he's within range and sight.
He does everything fine up until the point where he's meant to play the attack animation. Then he just goes back into idle mode and doesn't react to the player. What am I doing wrong this time?

Joined: Nov 8, Posts: I have this enemy that I want to follow the player among navigation and attack with a melee strike upon reaching him but the enemy just ends up bumping into the player instead.
The unfortunate part is I actually had the enemy attacking perfectly the first time but, due to Hard-Drive failure, I lost the entire game save for the models and textures I managed to extract from the apk file I had generated and now I can't figure out how I got it working the first time.
I can kill the enemy just fine but not much of an enemy if it can't hurt me. Perhaps someone could help me figure it out? Code CSharp :. Collections. Animator animator. Instantiate CyberVerminDead, gameObject. Destroy gameObject.

TonanBoraMay 27, Not only do I have it tagged as Player but children objects along with it. Thanks for the second tip, I'll keep a note of it but right now I'm concerned with my enemies posing an actual threat.The device or "platform" that a game is developed for and played on has a massive impact on the game development process.
While building a complete game, you will learn intermediate and advanced game development techniques in the Unity game engine. By the end of the course, you will understand how to develop, refine, package, and prepare your game for distribution on a variety of game platforms. Great course to give you fundamental experience creating a 2D platformer in Unity. Learned a lot and have a solid library of scripts to help me with my next project.
Totally worth it! A great instructor behind an amazing set of activities which provokes the student to work hard and achieve the submissions. This week we will continue to build our 2D platformer game, getting into some level design and gameplay enhancements, including adding an enemy to our game. Along the way we will start to introduce some Unity Editor tips and tricks and some more advanced programming concepts. As always, if you are having troubles with a concept, quiz, or technical issue with Unity or the project, you should post on the Discussion Forum to ask for help.
