Hello all, I am fairly new to unity and I am still figuring out the best practices for doing things in 2D, topd own games. I am currently mapping out the functionalities (and the corresponding Unity tools for achieving those funcitons) that I envisage having in my game. One of such things is the characters line of sight. For the purpose of demonstaration, consider this simple scene: https://imgur.com/a/sMrbEIH Here, the red blob is the player, the dark tiles are walls and light tiles are the floor. I want to know what the field of vision of the player is, so I draw some polygons to obscure the player's vision. It looks a bit like this: https://imgur.com/a/ybp2Pqn But the shadows look a bit too sharp; I'd like them to have softer edges, going gradually from completely solid in the body towards partial transparency at the edges. I am not sure hpow to achieve this. At the moment I am drawing some triangles using the MeshRenderer; they get re-calculated and re-rendered each frame and I am happy with the dynamic effect I achieve this way, but it would look much better with slightly softer edges. I was thinking about applying a different material or a shader onto my triangles, but the abundance and depth of choice makes the topic rather difficult to penetrate. Any advice for the newbie?
