Vec2 example

some basic vec2 commands
It could be expanded with some parms on x1, y1, x2, y2 or touches
Possibly after text on screen is implemented this can be expanded with some explanation

function setup() x1 = 123 y1 = 234 x2 = 67 y2 = 345 v1 = vec2(x1,y1) v2 = vec2(x2,y2) d1 = v1:dist(v2) l1 = v1:len() nv1 = v1:normalize() ra1 = v1:rotate( math.rad(-20)) end function draw() background(0, 0, 0, 0) stroke(212, 255, 0, 255) fill(255, 0, 0, 255) ellipse(v1.x,v1.y,50,50) fill(28, 48, 245, 255) ellipse(v2.x,v2.y,50,50) stroke(211, 255, 0, 255) strokeWidth(5) noFill() line(v2.x,v2.y,v2.x + d1,v2.y) line(v2.x,v2.y,v2.x,v2.y + d1) stroke(6, 252, 40, 255) line(10,10,l1 + 10, 10) ellipse(nv1.x * 300, nv1.y * 300,50,50) stroke(255, 0, 0, 255) ellipse(ra1.x,ra1.y,50,50) end

This the example i was looking for to start with vec2. Very basic but helpfull. Thanks

I could comment it up a bit and/or take the final code from https://bitbucket.org/TwoLivesLeft/codea/wiki/bvec2b and comment that up a bit.
