---Description--
Hi there! Today I show you how to create a simple melee attack script and a damage script for a potential enemy. We will also create an animation for it so that it looks more natural. It's not too much complicated, but there're some steps to follow.

Greetings from Russia! This was very helpful, good luck in your game development, you are doing really well! ;)

[@fpsbuilders4585]

Thank you! Really appreciated :)

[@fpsbuilders4585]

@Jokubas Remeika Greetings man!

[@aguy8007]

Bro, thanks for the animation code. Everywhere I looked, I couldn't find one that worked.

[@vicren5075]

* tip if this doesn't work set the animator in the script to be public and drag the animator on the knife into the script to give the script a reference.

[@fpsbuilders4585]

Thanks for helping the community

[@PowerPlayerSam]

Thanks for making my day amazing!

[@calebcrabtree8549]

So you dont have to wait to the end to see the double knives you just duplicate the knife and put it onto the parrel side of the knife

[@diogoschoeler2874]

in the conditions at the animator the options are: "blend" (in the place where it should be attacking) and "Greater" or "Less" where it should be "true" or "false". and it says tat parameter type attacking does not match, help pls
Nvm i found the error

cool, but how would i be able to make something like punching/kicking?
where it would not destroy but instead knock them back?

[@fpsbuilders4585]

It can be interesting to do a video about it

[@manlast643]

Simply add a rigidbody component to the object your knife collides with and then add a force to that rigidbody.
Here is a link to the documentation on addforce: docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html

The enemy won't get destroyed when I hit it! How do I fix this?

[@fpsbuilders4585]

Hello. Did you assign the tag to the Enemy?

[@Goodgis]

The Knife needs to have a rigid body. Just had the same problem!

Make sure you checked "Is Trigger" from your weapons collider.

[@Rals3i]

Great video, but I keep getting the error "Input button fire 1 is not setup" how do i fix this.

[@buildev22]

If you get this error than you want to got to edit > project settings > input manager, after getting there look to see if a "Fire 1" button is configured. If not then change the size of the input manager by one and create one yourself. Hope this helped :)

[@fpsbuilders4585]

As Elliot said

[@rategg3791]

pls i do not have Animator at the code

[@PoweringBacon]

Didnt work
Nvm i didnt add that false part

[@lukasvolcik5109]

As someone helped me, the attacking object needs a rigid body. It starts to detect the right collisions with it.

[@jackbudge2440]

Im running into the problem I have no errors popping up so I know its not code and well I've double checked and its the same but when I attack the enemy nothing happens it doesn't destroy him
Help?

[@fpsbuilders4585]

Probably something with the animator

[@jackbudge2440]

Sorry should have deleted the comment I had to add a rigid body and it worked thanks anyway!

create a parameter in the parameter tab called atack

[@bryanwangfilms]

Thanks it works great but how can you give the enemy's health.

[@friesandcats1919]

basically set up the script for the enemy, and give him a public float "health" and give it a set length, and have it so each hit makes the health go away by 1 instead of destroying the enemy, and destroy the enemy after the health reaches zero

[@bryanwangfilms]

@@friesandcats1919 Thx!

[@mintyunbox5307]

i came here to see how to swing and its what i got, thank you.

[@sausageswiper2397]

Your weapon works fine, but the only issue I see is that the weapon will destroy anything it touches without a mouse press (unless I did it wrong, which is a possibility). I would suggest turning off the collider upon ButtonUp and turning it on ButtonDown.

[@fpsbuilders4585]

Thanks for the adivce! You can also add an if specifing which tag should be hit by the weapon

[@Celcious]

add "if (collision.collider.tag == "Your enemy tag")
{
Destroy(collision.gameObject);
}"

i have to hold down left click for a second in order for my knife to hit is there a way to make it less long of a click?
