UE4 - 360° attack OP 12/29/15 (Tue) 14:15:42 6a3a11 No.24631

Greetings /adgd/,

I am looking for a good way to implement a 360° attack move into UE4.

No roundhouse, but on Z-axis.

What would be best?

What would be your take on it?

What specifically do you mean?

Just an attack that damages any enemy in a circle? I'd spawn a cylinder and if it overlaps an enemy do the damage

What I mean is the free choice of attacking direction in melee.

>press key

>swipe mouse

>get angle

>attack in that angle

everything combined with respective swinging. I do hope to do it via a form of blendspace with let's say 8 basic animations, or whatever works.

but how to get the mouse movement transformed to the attacking direction?

there is a "capture mouse" option, but i didnt get beyond

I'm gonna assume this is a 2D game, correct? At least in gameplay terms (be it top down or sidescroller).

>take mouse position

>project mouse position on game plane (the plane along which you move in 2D, so the ground plane if it's top down)

>get the projected point minus the character position

>get the vector against which you want to calculate the angle (probably forward vector of your player, perhaps up vector if it's a sidescroller)

>calculate angle between the two vectors

>congratulations

It is going to be an first person melee fighting game. See the video. It was made for an german imageboard, but the video parts show what the game does until now.

Since then I added an evasive step and sliding, if interest occures.

The last part shows the one attacking animation i have so far, found some guys who will help me with this project for further animations and in general already. Until now it is a fix animations that is just played, if the key is pressed.

What I want the attack move to be like:

> swipe mouse frome top right to bottom left --> current attack anim

> pull mouse from top to bottom --> overhead

> and so on, for every direction. the same for blocking and second hand attacks

And thanks for your input there, I guess I can kinda use it to get started / to the right direction anyway

Well there are many ways to do this, but what I would do is:

>take position where the click1 happened (from screenspace to world space)

>do the same for click2 (I call it click2 but I think you'll want it to be when the player releases the button after having dragged it)

>you now have the vector of the player's swing

>calculate the angle between that vector and the up or forward vector of your camera and use that to determine animation

Actually, you could use screenspace too now that I think about it, you'd get a 2D vector and then you could calculate its angle against either the X or the Y axis.

well, updates would take long time. guess /thread.

thanks again here
