I have currently created a simulation which mimics traffic rules with cars, pedestrians, crossings and lights and such. The next step I wanted to take with this is to let users build their own road lay outs using my pre-fab’d pieces of roads and I’m not really sure where to start. Ideally, I’d like it to have a window in which all road pieces are and they can simply ‘paint’ the roads down on to a terrain(floor), similar to how rollercoaster tycoons builder works. Included are screenshots of the kind of builder I want.
Any thoughts on where I can start for this or any tutorials as I’m kinda lost. I should add I am doing this in 3D. Thanks
