So Im at the point in my game where I need to tackle building things ingame by the player. Its a first person game, so you build chairs, desk, small houses and other objects. Im looking for good direction, some ideas how I do this. I have decent sized terrain that has mountains and slopes so I want the object to only be buildable on relatively flat spots, so when you can place I would like the objects to maybe glow red.
So what I think I need is maybe a tab at the bottom that I click on for item, then item spawns at mouse location, and is red until I place it on level terrain, then it turns green I left mouse click and boom its there.
Any ideas, thanks.
