Raw Blame History

// stb_tilemap_editor.h - v0.20 - Sean Barrett - http://nothings.org/stb
// placed in the public domain - not copyrighted - first released 2014-09
//
// Embeddable tilemap editor for C/C++
//
//
// COMPILING
//
// 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, uint 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);
// // this draws the tile image identified by 'id' in one of several
// // highlight modes (see STBTE_drawmode_* in the header section,
// // x0,y0,highlight:int; id:unsigned short
//
// #include "stb_tilemap_editor.h"
//
// Optionally you can define the following functions before the include;
// note these must be macros (which can just call a single function) so
// we can detect if you've defined them:
//
// [[ support for these 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.
//
// #define STBTE_DRAW_ICON(x0,y0,id,highlight) ...your code here...
// // this must draw a tile image identified by 'id' but now the
// // tile image must be drawn to fit in the tile palette, which
// // means it cannot exceed your specified palette spacing.
//
// 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 similiar 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 << 20) // 1MB
// #define STBTE_MAX_COPY 90000 // e.g. 300x300
//
// 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.)
//
// REVISION HISTORY
//
// 0.20 - 2014-09-27 - eraser tool, bugfixes, new colorscheme
// 0.10 - 2014-09-23 - initial release
//
// TODO
//
// Separate scroll state for each category
// Implement paint bucket
// Support STBTE_HITTEST_TILE above
// Support STBTE_HITTEST_ICON above
// ?Cancel drags by clicking other button? - may be fixed
// Object properties (per-tile properties)
// Finish support for toolbar at side
// Layer name buttons grow to fill box
