General / Re: Wrong position in View
« on: April 11, 2015, 12:15:25 pm »
The offset is needed for the current tile-position.
I copy a rectangle, then i paste it at mouse position.
So i copying tile for tile from old rect to new rect. In my array all is right, but i need to set the new Vertexarray position and this fails when i have moved the view or zoomed.
Here I paste you the full function:
