Move around with the mouse The idea is that the triangles formed are the visible regions. Note: only the triangles with NO YELLOW in them are visible. You can make any blocks you want. See inside and there is a custom block titled "Make a block at X: 1 Y: 1 Width: 1 Height: 1." That's all you have to do - it will automatically be put into the system and work.
This is an engine that will show top-down visibility. As of now, it is highly incomplete and hence it is on my test. It actually works perfectly if you stop and think about it for a while. Once I add shading it will be a lot clearer. Don't hold your breath though. I'm aiming to make something like this: http://ncase.me/sight-and-light/ Any help is appreciated. High WIP. All pen rendered, no costumes. This is gonna get laggy as heck once I add shading, so use this: http://phosphorus.github.io/app.html?id=39569908&turbo=false&full-screen=false Note, we are assuming you have eyes on the back of your head.
