Hi , I am trying to develop basic programming interface for children, as a beginner at Unity Engine I can't understand complicated scripts. Even I watched almost all tutorials about drag and drop process still I don't know how to implement it to my project . I tried to use this asset : https://www.assetstore.unity3d.com/en/#!/content/66449 but its script is reallt complicated for me and I couldn't edit this script as I intented. My example panel below here; I need to achive few things ; - Drag a object from upper panel and drop it to lower panel - Learn which lower panel has which objects. For exp; First lower panel has up button and second lower button has right button and so on. How can I simply do this? Where do I start? Thank you.
