Help with Newrect

Solar2D General Questions/Discussion
#1

Hi,

I am trying to draw a line using newRect between two points.
I have been trying to use the rotation to get the angle right but am doing something wrong… does anyone have any code snippets? or can someone tell me what I am doing wrong? (I can’t use the newline method, I need to use the newrect)

[code]

local diffX = Startx - EndX
local diffY = Starty- Endy
local sizeofLine = math.sqrt (math.pow(diffX,2) + math.pow(diffY,2) ) – use pythagoras
local angleofLine = math.deg (math.tan (diffY/diffX)) – use Tan = opp.adj
angleofLine = 90 - angleofLine – work out the rotation angle

Line = display.newRect( Startx, Starty, 10, sizeofLine )
Line:rotate(angleofLine)

worked it out…

if anyone else is interested

[code]
local diffX = Startx - EndX
local diffY = Starty- Endy
local sizeofLine = math.sqrt (math.pow(diffX,2) + math.pow(diffY,2) ) – use pythagoras
local angleofLine = math.deg (math.atan (diffX/diffY)) – use Tan = opp.adj
angleofLine = 90 - angleofLine – work out the rotation angle

Line = display.newRect( Startx, Starty, 10, sizeofLine )
Line:rotate(-angleofLine)
