How to rotate a velocity (for avoid obstacle AI)

0 votes

I'm a noob at programming so I don't know how to draw sth like thisimage

So I created this script 

func _ready():
    ray.resize(8)
    for i in 8:
        ray[i] = position + Vector2(1,1).rotated(i * PI * 2) * 100
func _draw():
    for i in ray:
        draw_line(position, i , Color(255,0,0),1)

(I'm trying to make my own avoiding obstacle AI without Navigation because I have already used normal pathfinding for my project)

I have researched a lot about this but I still don't know why this doesn't work, if you know how to fix this please tell me (Actually if you know a way to make the AI follow the player and avoiding obstacle at the same time without Navigation)

Don't understand why the image is not showing, go here instead : Image

It's looking like you're rotating each element of ray[] by a multiple of 2pi radians (one full circle). From your picture you'd want to rotate each element by pi/4 so that you get 8 lines. Am I understanding you correctly?
