|
// FAQ
|
|
//
|
|
// Q: What counts as a tilemap for this library?
|
|
//
|
|
// A: An array of rectangles, where each rectangle contains a small
|
|
// stack of images.
|
|
//
|
|
// Q: What are the limitations?
|
|
//
|
|
// A: Maps are limited to 4096x4096 in dimension.
|
|
// Each map square can only contain a stack of at most 32 images.
|
|
// A map can only use up to 32768 distinct image tiles.
|
|
//
|
|
// Q: How do I compile this?
|
|
//
|
|
// A: You need to #define several symbols before #including it, but only
|
|
// in one file. This will cause all the function definitions to be
|
|
// generated in that file. See the "HOW TO COMPILE" section.
|
|
//
|
|
// Q: What advantages does this have over a standalone editor?
|
|
//
|
|
// A: For one, you can integrate the editor into your game so you can
|
|
// flip between editing and testing without even switching windows.
|
|
// For another, you don't need an XML parser to get at the map data.
|
|
//
|
|
// Q: Can I live-edit my game maps?
|
|
//
|
|
// A: Not really, the editor keeps its own map representation.
|
|
//
|
|
// Q: How do I save and load maps?
|
|
//
|
|
// A: You have to do this yourself. The editor provides serialization
|
|
// functions (get & set) for reading and writing the map it holds.
|
|
// You can choose whatever format you want to store the map to on
|
|
// disk; you just need to provide functions to convert. (For example,
|
|
// I actually store the editor's map representation to disk basically
|
|
// as-is; then I have a single function that converts from the editor
|
|
// map representation to the game representation, which is used both
|
|
// to go from editor-to-game and from loaded-map-to-game.)
|
|
//
|
|
// Q: I want to have tiles change appearance based on what's
|
|
// adjacent, or other tile-display/substitution trickiness.
|
|
//
|
|
// A: You can do this when you convert from the editor's map
|
|
// representation to the game representation, but there's
|
|
// no way to show this live in the editor.
|
|
//
|
|
// Q: The editor appears to be put map location (0,0) at the top left?
|
|
// I want to use a different coordinate system in my game (e.g. y
|
|
// increasing upwards, or origin at the center).
|
|
//
|
|
// A: You can do this when you convert from the editor's map
|
|
// representation to the game representation. (Don't forget to
|
|
// translate link coordinates as well!)
|
|
//
|
|
// Q: The editor appears to put pixel (0,0) at the top left? I want
|
|
// to use a different coordinate system in my game.
|
|
//
|
|
// A: The editor defines an "editor pixel coordinate system" with
|
|
// (0,0) at the top left and requires you to display things in
|
|
// that coordinate system. You can freely remap those coordinates
|
|
// to anything you want on screen.
|
|
//
|
|
// Q: How do I scale the user interface?
|
|
//
|
|
// A: Since you do all the rendering, you can scale up all the rendering
|
|
// calls that the library makes to you. If you do, (a) you need
|
|
// to also scale up the mouse coordinates, and (b) you may want
|
|
// to scale the map display back down so that you're only scaling
|
|
// the UI and not everything. See the next question.
|
|
//
|
|
// Q: How do I scale the map display?
|
|
//
|
|
// A: Use stbte_set_spacing() to change the size that the map is displayed
|
|
// at. Note that the "callbacks" to draw tiles are used for both drawing
|
|
// the map and drawing the tile palette, so that callback may need to
|
|
// draw at two different scales. You should choose the scales to match
|
|
// You can tell them apart because the
|
|
// tile palette gets NULL for the property pointer.
|
|
//
|
|
// Q: How does object editing work?
|
|
//
|
|
// A: One way to think of this is that in the editor, you're placing
|
|
// spawners, not objects. Each spawner must be tile-aligned, because
|
|
// it's only a tile editor. Each tile (stack of layers) gets
|
|
// an associated set of properties, and it's up to you to
|
|
// determine what properties should appear for a given tile,
|
|
// based on e.g. the spawners that are in it.
|
|
//
|
|
// Q: How are properties themselves handled?
|
|
//
|
|
// A: All properties, regardless of UI behavior, are internally floats.
|
|
// Each tile has an array of floats associated with it, which is
|
|
// passed back to you when drawing the tiles so you can draw
|
|
// objects appropriately modified by the properties.
|
|
//
|
|
// Q: What if I want to have two different objects/spawners in
|
|
// one tile, both of which have their own properties?
|
|
//
|
|
// A: Make sure STBTE_MAX_PROPERTIES is large enough for the sum of
|
|
// properties in both objects, and then you have to explicitly
|
|
// map the property slot #s to the appropriate objects. They'll
|
|
// still all appear in a single property panel; there's no way
|
|
// to get multiple panels.
|
|
//
|
|
// Q: Can I do one-to-many linking?
|
|
//
|
|
// A: The library only supports one link per tile. However, you
|
|
// can have multiple tiles all link to a single tile. So, you
|
|
// can fake one-to-many linking by linking in the reverse
|
|
// direction.
|
|
//
|
|
// Q: What if I have two objects in the same tile, and they each
|
|
// need an independent link? Or I have two kinds of link associated
|
|
// with a single object?
|
|
//
|
|
// A: There is no way to do this. (Unless you can reverse one link.)
|
|
//
|
|
// Q: How does cut & paste interact with object properties & links?
|
|
//
|
|
// A: Currently the library has no idea which properties or links
|
|
// are associated with which layers of a tile. So currently, the
|
|
// library will only copy properties & links if the layer panel
|
|
// is set to allow all layers to be copied, OR if you set the
|
|
// "props" in the layer panel to "always". Similarly, you can
|
|
// set "props" to "none" so it will never copy.
|
|
//
|
|
// Q: What happens if the library gets a memory allocation failure
|
|
// while I'm editing? Will I lose my work?
|
|
//
|
|
// A: The library allocates all editor memory when you create
|
|
// the tilemap. It allocates a maximally-sized map and a
|
|
// fixed-size undo buffer (and the fixed-size copy buffer
|
|
// is static), and never allocates memory while it's running.
|
|
// So it can't fail due to running out of memory.
|
|
//
|
|
// Q: What happens if the library crashes while I'm editing? Will
|
|
// I lose my work?
|
|
//
|
|
// A: Yes. Save often.

|
|
// HOW TO COMPILE
|
|
//
|
|
// This header file contains both the header file and the
|
|
// implementation file in one. To create the implementation,
|
|
// in one source file define a few symbols first and then
|
|
// include this header:
|
|
//
|
|
// #define STB_TILEMAP_EDITOR_IMPLEMENTATION
|
|
// // this triggers the implementation
|
|
//
|
|
// void STBTE_DRAW_RECT(int x0, int y0, int x1, int y1, unsigned int color);
|
|
// // this must draw a filled rectangle (exclusive on right/bottom)
|
|
// // color = (r<<16)|(g<<8)|(b)
|
|
//
|
|
// void STBTE_DRAW_TILE(int x0, int y0,
|
|
// unsigned short id, int highlight, float *data);
|
|
// // this draws the tile image identified by 'id' in one of several
|
|
// // highlight modes (see STBTE_drawmode_* in the header section);
|
|
// // if 'data' is NULL, it's drawing the tile in the palette; if 'data'
|
|
// // is not NULL, it's drawing a tile on the map, and that is the data
|
|
// // associated with that map tile
|
|
//
|
|
// #include "stb_tilemap_editor.h"
|
|
//
|
|
// Optionally you can define the following functions before the include;
|
|
// note these must be macros (but they can just call a function) so
|
|
// this library can #ifdef to detect if you've defined them:
|
|
//
|
|
// #define STBTE_PROP_TYPE(int n, short *tiledata, float *params) ...
|
|
// // Returns the type of the n'th property of a given tile, which
|
|
// // controls how it is edited. Legal types are:
|
|
// // 0 /* no editable property in this slot */
|
|
// // STBTE_PROP_int /* uses a slider to adjust value */
|
|
// // STBTE_PROP_float /* uses a weird multi-axis control */
|
|
// // STBTE_PROP_bool /* uses a checkbox to change value */
|
|
// // And you can bitwise-OR in the following flags:
|
|
// // STBTE_PROP_disabled
|
|
// // Note that all of these are stored as floats in the param array.
|
|
// // The integer slider is limited in precision based on the space
|
|
// // available on screen, so for wide-ranged integers you may want
|
|
// // to use floats instead.
|
|
// //
|
|
// // Since the tiledata is passed to you, you can choose which property
|
|
// // is bound to that slot based on that data.
|
|
// //
|
|
// // Changing the type of a parameter does not cause the underlying
|
|
// // value to be clamped to the type min/max except when the tile is
|
|
// // explicitly selected.
|
|
//
|
|
// #define STBTE_PROP_NAME(int n, short *tiledata, float *params) ...
|
|
// // these return a string with the name for slot #n in the float
|
|
// // property list for the tile.
|
|
//
|
|
// #define STBTE_PROP_MIN(int n, short *tiledata) ...your code here...
|
|
// #define STBTE_PROP_MAX(int n, short *tiledata) ...your code here...
|
|
// // These return the allowable range for the property values for
|
|
// // the specified slot. It is never called for boolean types.
|
|
//
|
|
// #define STBTE_PROP_FLOAT_SCALE(int n, short *tiledata, float *params)
|
|
// // This rescales the float control for a given property; by default
|
|
// // left mouse drags add integers, right mouse drags adds fractions,
|
|
// // but you can rescale this per-property.
|
|
//
|
|
// #define STBTE_FLOAT_CONTROL_GRANULARITY ... value ...
|
|
// // This returns the number of pixels of mouse motion necessary
|
|
// // to advance the object float control. Default is 4
|
|
//
|
|
// #define STBTE_ALLOW_LINK(short *src, float *src_data, \
|
|
// short *dest, float *dest_data) ...your code...
|
|
// // this returns true or false depending on whether you allow a link
|
|
// // to be drawn from a tile 'src' to a tile 'dest'. if you don't
|
|
// // define this, linking will not be supported
|
|
//
|
|
// #define STBTE_LINK_COLOR(short *src, float *src_data, \
|
|
// short *dest, float *dest_data) ...your code...
|
|
// // return a color encoded as a 24-bit unsigned integer in the
|
|
// // form 0xRRGGBB. If you don't define this, default colors will
|
|
// // be used.
|
|
//
|
|
//
|
|
// [[ support for those below is not implemented yet ]]
|
|
//
|
|
// #define STBTE_HITTEST_TILE(x0,y0,id,mx,my) ...your code here...
|
|
// // this returns true or false depending on whether the mouse
|
|
// // pointer at mx,my is over (touching) a tile of type 'id'
|
|
// // displayed at x0,y0. Normally stb_tilemap_editor just does
|
|
// // this hittest based on the tile geometry, but if you have
|
|
// // tiles whose images extend out of the tile, you'll need this.
|
|
//
|
|
// ADDITIONAL CONFIGURATION
|
|
//
|
|
// The following symbols set static limits which determine how much
|
|
// memory will be allocated for the editor. You can override them
|
|
// by making similar definitions, but memory usage will increase.
|
|
//
|
|
// #define STBTE_MAX_TILEMAP_X 200 // max 4096
|
|
// #define STBTE_MAX_TILEMAP_Y 200 // max 4096
|
|
// #define STBTE_MAX_LAYERS 8 // max 32
|
|
// #define STBTE_MAX_CATEGORIES 100
|
|
// #define STBTE_UNDO_BUFFER_BYTES (1 << 24) // 16 MB
|
|
// #define STBTE_MAX_COPY 90000 // e.g. 300x300
|
|
// #define STBTE_MAX_PROPERTIES 10 // max properties per tile
|
|
//

|
// API

|
// Further documentation appears in the header-file section below.
|
|
//
|
|
// EDITING MULTIPLE LEVELS
|
|
//
|
|
// You can only have one active editor instance. To switch between multiple
|
|
// levels, you can either store the levels in your own format and copy them
|
|
// in and out of the editor format, or you can create multiple stbte_tilemap
|
|
// objects and switch between them. The latter has the advantage that each
|
|
// stbte_tilemap keeps its own undo state. (The clipboard is global, so
|
|
// either approach allows cut&pasting between levels.)

/////////////////////// undo system ////////////////////////
|
|
|
|
// the undo system works by storing "commands" into a buffer, and
|
|
// then playing back those commands. undo and redo have to store
|
|
// the commands in different order.
|
|
//
|
|
// the commands are:
|
|
//
|
|
// 1) end_of_undo_record
|
|
// -1:short
|
|
//
|
|
// 2) end_of_redo_record
|
|
// -2:short
|
|
//
|
|
// 3) tile update
|
|
// tile_id:short (-1..32767)
|
|
// x_coord:short
|
|
// y_coord:short
|
|
// layer:short (0..31)
|
|
//
|
|
// 4) property update (also used for links)
|
|
// value_hi:short
|
|
// value_lo:short
|
|
// y_coord:short
|
|
// x_coord:short
|
|
// property:short (256+prop#)
|
|
//
|
|
// Since we use a circular buffer, we might overwrite the undo storage.
|
|
// To detect this, before playing back commands we scan back and see
|
|
// if we see an end_of_undo_record before hitting the relevant boundary,
|
|
// it's wholly contained.
|
|
//
|
|
// When we read back through, we see them in reverse order, so
|
|
// we'll see the layer number or property number first
|
|
//
|
|
// To be clearer about the circular buffer, there are two cases:
|
|
// 1. a single record is larger than the whole buffer.
|
|
// this is caught because the end_of_undo_record will
|
|
// get overwritten.
|
|
// 2. multiple records written are larger than the whole
|
|
// buffer, so some of them have been overwritten by
|
|
// the later ones. this is handled by explicitly tracking
|
|
// the undo length; we never try to parse the data that
|
|
// got overwritten
|
|

// given two points, compute the length between them
