\nhttp:\/\/unitycoder.com\/upload\/demos\/PerlinDungeons1\/<\/a> (v1.0 : some bugs in webplayer build: floor & roof normals \/ tangents broken?, minimap is broken..)<\/p>\n
\n– Creates 2D texture and array with perlin noise (not needed, since you could check x,y perlin values directly anyways..)
\n– First pass, create floors (with basic RLE<\/a> – to save few vertices.. 1 floor can be long as seen in the image):
\n-> If we hit empty grid point, save x & y values
\n-> Until we hit a filled grid point (wall), then draw floor mesh from saved x & y values until here
\n-> Scale UV based on floor piece length (so that tiling is still correct)
\n– Second pass: Similar thing for walls (currently single pieces..would save vertices to draw long walls as 2 faces only)
\n– Maximum: 256×256 grid (mesh cannot have more than 65k vertices..could split it to new mesh)
\n– Adjustable wall height
\n– Added: basic minimap (guitexture with texture2D<\/a> & setpixel..)
\n– Walls, floor, roof are separate meshes, easier to adjust their texturing (current textures are from opengameart.org<\/a>)
\n– Added: Tangents for floor & roof meshes (so can use normal maps), founded the info from minecraft thread<\/a>.
\n– Added: Footstep sounds (script & sounds from: bootcamp demo<\/a>, modified the script to play sounds with autofire timer<\/a>..)
\n– Added: Ambient cave sound (from: http:\/\/www.freesfx.co.uk<\/a> )
\n– Added: waterdrop particles from roof
\n– Added: Cave mesh saving from playmode<\/a>
\n– Added: HeadBobber<\/a> (had to move fps camera under dummy gameobject and assign bobber to that gameobject..)
\n– Tried: GridMove<\/a>, works fine but rather use free moving for now..<\/p>\n
\nIdeas:<\/strong>
\n– Actually floor and ceiling could be just single plane..
\n– For texturing..use secondary perlin noise for “terrain” variation? (moss, rocky, sand..)
\n– Its single mesh, needs texture atlas for multiple materials?
\n– Generate mob spawned locations too? Other objects too?
\n– Generate floors and stairs and holes to other floors? (needs 3D perlin noise, currently using Mathf.PerlinNoise();)
\n– Level saving as an asset? (or could use OBJ save from angry bots?)
\n– Digging\/breaking the walls?
\n– Volumetric fog or other effects? (since we are inside limited 2D grid, could do visibility casting & fake shadow stuff too?)
\n– Tesselation shaders (must use for something?! rounding the objects? or with wall displacement mapping?)<\/p>\n![\"perlin_cave_maker2\"](\"https:\/\/i0.wp.com\/unitycoder.com\/blog\/wp-content\/uploads\/2013\/01\/perlin_cave_maker2.jpg?resize=680%2C376\")
