Hello, I want to build a interior decor type of game. Top view type. You drag items like sofa, chair, bed from a side menu to a tile map based room.

Can you tell me how to do it? Ideas?

TIA

Your question is way too broad. There are a thousand ways to do this depending on language/platform and what you have already. But it would involve multiple steps, such as having an inventory system, mouse picking/dragging, and adding objects to your scene at runtime. Once you have these in place you can string them together.

You will likely get better responses if you mention what language or engine you are using and what you have tried already. Also posting in the right forum might help, since this is hardly an AI question.
