Transition To Loop

Getting Started Newbie Questions
#1

I’m still trying to move an object in a square movement and I’m having two problems.  My code is below

  1.  It goes the full square but then it stops.  I cannot get it to loop.

I would really appreciate any thoughts on how to make the loop continue.

  1. This method is causing a bad memory leak.  I’ve tried pausing the timers and transitions in multiple places but it seem to stop the code.

I would really appreciate any thoughts on how to plug this memory leak.

THANKS!

Here is a unified mover example, hope it helps:

local function squareMover( obj, loops, size, time ) size = size or 100 time = (time or 1000)/4 loops = loops or 1 local corner = 1 local corners = {} corners[1] = { obj.x, obj.y } corners[2] = { obj.x, obj.y - size } corners[3] = { obj.x + size, obj.y - size } corners[4] = { obj.x + size, obj.y } local function nextMove( self ) if( corner == 1 and loops \<= 0 ) then return end corner = corner + 1 if( corner \> 4 ) then corner = 1 loops = loops - 1 end transition.to( self, { x = corners[corner][1], y = corners[corner][2], time = time, onComplete = nextMove }) end nextMove( obj ) end local tmp = display.newCircle( 150, 150, 10 ) squareMover( tmp ) local tmp2 = display.newCircle( 300, 150, 10 ) squareMover( tmp2, 2 )

WOW - THANK YOU SO MUCH!!!

I adapted to my table objects and it works exactly as I envisioned and it isn’t causing a memory leak.

I really appreciate the help.

Have a great day.
