I think I must be doing something completely wrong. What I want to achieve is a triangle that rotates to point at a dot. I started out by Using the formula angle = math.deg(atan2(y2-y1,x2-x1)), then when failing, I tried creating vec2s and using angle = math.deg(vec2a:angleBetween(vec2b)). Still not pointing correctly. Maybe I am doing my rotation wrong. I would appreciate any help getting this working. Please see code below, my intent was that the triangle should always point at the dot, regardless of the value of the parameters

```
function setup()
parameter("x1",100,600,100)
parameter("y1",100,600,100)
parameter("x2",100,600,400)
parameter("y2",100,600,400)
end
function draw()
vec2a = vec2(x1,y1)
vec2b = vec2(x2,y2)
myangle = vec2a:angleBetween(vec2b)
background(40, 40, 50)
strokeWidth(5)
stroke(0, 0, 0, 255)
--print the target to point at
ellipse(x1,y1,5,5)
pushMatrix()
--now I translate to where I want to draw my triangle
--then I rotate to the angle
--and draw
translate(x2,y2)
rotate(math.deg(myangle))
drawtriangle()
popMatrix()
end
function drawtriangle()
strokeWidth(8)
stroke(255, 255, 255, 255)
line(0,0,20,-60)
line(20,-60,-20,-60)
line(-20,-60,0,0)
end
```

Any tips appreciated, thanks.
