Computer science ! 1.the unit guides you on how to use prefab assets (downloaded for free online) to create levels; for example, creating walls or buildings. besides pure “looks” or aesthetics, name at least one reason you might be better served by creating an asset “from scratch” rather than using a prefab asset? 2.think about a game you played recently that had interesting level design. what are some of the non-gameplay-essential elements the game included that made the levels more immersive? for either that game or another, name at least one “interactive” element the game included that increased immersion. 3.name at least one level design consideration you have to keep in mind in 3d games that you don’t need to consider in 2d games. then, name a second level design consideration/feature/limitation that is more relevant to 2d games than 3d games. 4.during what kinds of tasks might you use a sculpting tool with high opacity? when might you use low opacity? 5.how might you tie a landscape’s textures directly into gameplay?
