Hi! I create any simple program and game for iPhone, but new on the mac os programming and cocoa. I want create editor map. It create plist file with image center coordinates and angles rotation added on the box area; Conception: Step 1. add background (it is not editable) Step 2. Images from table can be added to right area (click or drag). We can add more duplicate this object in the area. Added onto area objects can be moved within background image. We can get coordinates all images, can rotate it around center. Finally it's all will be exported into plist file as group image by name and items with coordinates. My question is: how to implement it. This is a joke. ) My questions are: What the way create draggable object? Can i use image, or not? What i should use for area when object will be place? It's can be box view or other type view? What the way create plist file? I will be grateful for any tips and tutorials describing part of this task.
