# Procedural Mapping ### _With Regards To RemieRichards_ --- ## Coder Informative Readme ### mapGenerator: Desc: a _mapGenerator_ is a master datum that collects and syncs all _mapGeneratorModules_ in its modules list. ### defineRegion(var/turf/Start, turf/End, replace = 0) Example: `defineRegion(locate(1,1,1),locate(5,5,5),0)` Desc: Sets the bounds of the _mapGenerator's_ "map". ### defineCircularRegion(var/turf/Start, turf/End, replace = 0) Example: `defineCircularRegion(locate(1,1,1),locate(5,5,5),0)` Desc: Sets the _mapGenerator's_ "map" as a circle, with center in the middle of Start and End's X,Y,Z coordinates. ### undefineRegion() Example: `undefineRegion()` Desc: Empties the map generator list. ### checkRegion(var/turf/Start, turf/End) Example: `checkRegion(locate(1,1,1), locate(5,5,5))` Desc: Checks if a rectangle between Start's coords and End's coords is valid. Existing Calls: `mapGenerator/defineRegion(), mapGenerator/defineCircularRegion()` ### generate() Example: `generate()` Desc: Orders all _mapGeneratorModules_ in the modules list to `generate()`. ### generateOneTurf(var/turf/T) Example: `generateOneTurf(locate(1,1,1))` Desc: Orders all _mapGeneratorModules_ in the modules list to `place(T)` on this turf. ### initialiseModules() Example: `initialiseModules()` Desc: Replaces all typepaths in the modules list with actual `/datum/map_generator/Module` types. Existing Calls: `mapGenerator/New()` ### syncModules() Example: `syncModules()` Desc: Sets the Mother variable on all _mapGeneratorModules_ in the modules list to this _mapGenerator_. Existing Calls: `initialiseModules(),generate(),generateOneTurf()` --- ### mapGeneratorModule Desc: a mapGeneratorModule has spawnableAtoms and spawnableTurfs lists which it will generate on turfs in its mother's map based on cluster variables. ### sync(var/datum/map_generator/mum) Example: `sync(a_mapGenerator_as_a_variable)` Desc: Sets the Mother variable to the mum argument. Existing Calls: `mapGenerator/syncModules()` ### generate() Example: `generate()` Desc: Calls place(T) on all turfs in its mother's map Existing Calls: `mapGenerator/generate()` ### place(var/turf/T) Example: `place(locate(1,1,1)) ` Desc: Run this _mapGeneratorModule's_ effects on this turf (Spawning atoms, Changing turfs). Existing Calls: `mapGenerator/generate()`, `mapGenerator/generateOneTurf()` ### checkPlaceAtom(var/turf/T) Example: `checkPlace(locate(1,1,1))` Desc: Checks if the turf is valid for placing atoms. Existing Calls: `place()` --- ## Mapper Friendly Readme Simple Workflow: 1. Define a/some mapGeneratorModule(s) to your liking, choosing atoms and turfs to spawn - I chose to split Turfs and Atoms off into separate modules, but this is NOT required. - A mapGeneratorModule may have turfs AND atoms, so long as each is in its appropriate list 2. Define a mapGenerator type who's modules list contains the typepath(s) of all the module(s) you wish to use - The order of the typepaths in the modules list is the order they will happen in, this is important for clusterCheckFlags. 3. Take notes of the Bottom Left and Top Right turfs of your rectangular "map"'s coordinates - X, Y, AND Z. Yes, you can create 3D "maps" by having differing Z coordinates 4. Create the mapGenerator type you created 5. Call `yourMapGeneratorType.defineRegion(locate(X,Y,Z), locate(X,Y,Z))` - The above X/Y/Zs are the coordinates of the start and end turfs, the locate() simply finds the turf for the code 6. Call `yourMapGeneratorType.generate()`, this will cause all the modules in the generator to build within the map bounds Option Suggestions: - Have separate modules for Turfs and Atoms, this is not enforced, but it is how I have structured my nature example. - If your map doesn't look quite to your liking, simply jiggle with the variables on your modules and the type probabilities. - You can mix and map premade areas with the procedural generation, for example mapping an entire flat land but having code generate just the grass tufts. Using the Modules list Simply think of it like each module is a layer in a graphics editing program! To help you do this templates such as /mapGeneratorModule/bottomLayer have been provided with appropriate default settings. These are located near the bottom of `mapGeneratorModule.dm`. You would order your list left to right, top to bottom. For example: `modules = list(bottomLayer,nextLayer,nextNextLayer)`, etc. Variable Breakdown (For Mappers): ### mapGenerator - map - INTERNAL, do not touch - modules - A list of typepaths of mapGeneratorModules ### mapGeneratorModule - mother - INTERNAL, do not touch - spawnableAtoms - A list of typepaths and their probability to spawn, eg: `spawnableAtoms = list(/obj/structure/flora/tree/pine = 30)` - spawnableTurfs - A list of typepaths and their probability to spawn, eg: `spawnableTurfs = list(/turf/unsimulated/floor/grass = 100)` - clusterMax - The max range to check for something being "too close" for this atom/turf to spawn, the true value is random between clusterMin and clusterMax - clusterMin - The min range to check for something being "too close" for this atom/turf to spawn, the true value is random between clusterMin and clusterMax - clusterCheckFlags - A Bitfield that controls how the cluster checks work, All based on clusterMin and clusterMax guides - allowAtomsOnSpace - A Boolean for if we allow atoms to spawn on space tiles ### clusterCheckFlags flags: CLUSTER_CHECK_NONE 0 //No checks are done, cluster as much as possible CLUSTER_CHECK_DIFFERENT_TURFS 2 //Don't let turfs of DIFFERENT types cluster CLUSTER_CHECK_DIFFERENT_ATOMS 4 //Don't let atoms of DIFFERENT types cluster CLUSTER_CHECK_SAME_TURFS 8 //Don't let turfs of the SAME type cluster CLUSTER_CHECK_SAME_ATOMS 16 //Don't let atoms of the SAME type cluster CLUSTER_CHECK_SAMES 24 //Don't let any of the same type cluster CLUSTER_CHECK_DIFFERENTS 6 //Don't let any different types cluster CLUSTER_CHECK_ALL_TURFS 10 //Don't let ANY turfs cluster same and different types CLUSTER_CHECK_ALL_ATOMS 20 //Don't let ANY atoms cluster same and different types CLUSTER_CHECK_ALL 30 //Don't let anything cluster, like, at all
