please test my code.

run it with and without line 31 to see different.

it seem like localToContent() function make change obj xReferent,yReferent.

I don’t think you are going to get a very positive response if you just dump a link to some code without explaining your problem.  

I’ve just compiled your code, it works fine.

#3

Here is consolidated version of the code showing what happens

local g = display.newGroup() display.newRect(g, 0, 0, 100, 50) g.xReference, g.yReference = 50, 25 g.x, g.y = 100, 100 g.rotation = 60 -- everything is OK if no rotation involved g:localToContent(0, 0) -- comment/uncomment changes position on screen g.xReference, g.yReference = 75, 25 -- setting different ref point after calling localToContent causes the effect g.x, g.y = 100, 100 local point = display.newCircle(0, 0, 5) point.x, point.y = 100, 100 point:setFillColor(225, 0, 0)

Generally speaking you should be using :localToContent() to return numbers; it converts local position into stage (screen) position. By not calling it I suppose it could be changing reference or somehow adjusting the object itself.

What do you need to use the command for?

#5

But I need localToContent() function to get some calculate. I need a loop : set positon - calculation. so that become worng from second loop. I can’t set position exactly -> can’t calculation.

Thanks Lerg for make it code smaller.
