## How do I initialize a game
Initialize the global game object with info about your game
```c
strncpy((char *)&game.name, "sdl3-gametest", 256);
strncpy((char *)&game.version, "0.0.1", 32);
strncpy((char *)&game.uri, "net.aklabs.games.sdl3-gametest", 256);
```
Call the game initialization routines and lock the game state for further initialization
```c
PASS(e, akgl_game_init());
PASS(e, akgl_game_state_lock());
```
If you have a registry properties file, load it. If you don't have a properties file, use `akgl_set_property("prop_name", "prop_value")` to populate the required game properties.
```c
PASS(e, akgl_registry_load_properties(YOUR_REGISTR_FILEPATH));
```
Initialize your physics engine and renderer of choice
```c
PASS(e, akgl_render_init2d(renderer));
PASS(e, akgl_physics_init_arcade(physics));
```
Unlock the game state
```c
PASS(e, akgl_game_state_unlock());
```
## What is in a properties file (or, What properties must I set if I don't have one?)
```json
{
"properties": {
"game.screenwidth": "640",
"game.screenheight": "480",
"physics.gravity.y": "1024.0",
"physics.drag.y": "1.0"
}
}
```
Physics properties (gravity and drag along X, Y and Z) are optional and default to `0`.
## How do I update and render the game world in my main loop
In your game loop (or in your `SDL_AppIterate` method), lock the game state, call the game update function, and then unlock the game state
```c
PASS(e, akgl_game_state_lock());
PASS(e, renderer->frame_start(renderer));
SDL_RenderClear(renderer->sdl_renderer);
PASS(e, akgl_game_update(NULL));
PASS(e, renderer->frame_end(renderer));
PASS(e, akgl_game_state_unlock());
```
## How do I get an actor on screen
Load a sprite for a character. Sprites are JSON documents describing 2D sprites, frames, and looping. Sprites are named, and sprite names must be unique.
```c
PASS(e, akgl_sprite_load_json(SOME_FILENAME))
```
Load a character from a JSON file. Characters map sprites to actor states and define physics characteristics like movement speed. Each character is named, and character names must be unique.
```c
PASS(e, akgl_character_load_json(SOME_FILENAME))
```
You don't strictly have to load sprites and characters from json files, you can initialize them yourself, it's just tedious work. Here's an example of initializing a 32x32 sprite from a spritesheet that uses the first 4 frames in a looping animation.
```c
akgl_SpriteSheet *sheet;
akgl_Sprite *sprite;
akgl_Character *character;
PASS(e, akgl_heap_next_spritesheet(&sheet);
PASS(e, akgl_spritesheet_initialize(sheet, 32, 32, IMAGE_FILENAME));
PASS(e, akgl_heap_next_sprite(&sprite));
PASS(e, akgl_sprite_initialize(sprite, SPRITE_NAME, &sheet);
sprite->frames = 4;
sprite->frameids = [0, 1, 2, 3];
sprite->width = 32;
sprite->height = 32;
sprite->speed = 1000;
sprite->loop = true;
strncpy((char *)&sprite->name, "SPRITE NAME", AKGL_SPRITE_MAX_NAME_LENGTH);
PASS(e, akgl_heap_next_character(&character));
PASS(e, akgl_character_initialize(&character, "CHAR NAME"));
PASS(e, akgl_character_sprite_add(&character, &sprite, STATE_MASK));
// Set the character acceleration and scale if desired
character->ax = 64.0;
character->ay = 64.0;
character->sx = 2.0;
character->sy = 2.0;
```
Initialize an actor. Actors are named ("player", "Quest NPC", whatever) and names must be unique.
```c
akgl_Actor *myactor = NULL;
PASS(e, akgl_heap_next_actor(&myactor);
PASS(e, akgl_actor_initialize(&myactor, "ACTOR_NAME"));
```
Assign a character to the actor by looking up the `akgl_Character` from the AKGL registry and assign it.
```c
myactor->basechar = SDL_GetPointerProperty(
AKGL_REGISTRY_CHARACTER,
"CHARACTER_NAME",
NULL);
FAIL_ZERO_BREAK(e, myactor->basechar, AKERR_REGISTRY, "Character missing");
```
Give the actor a position and a state, and turn it visible.
```c
myactor->state = 9AKGL_ACTOR_STATE_ALIVE | AKGL_ACTOR_STATE_FACE_LEFT);
myactor->x = 320;
myactor->y = 240;
myactor->visible = true;
```
## What are in Sprite and Character files
Sprite files:
```json
{
"spritesheet": {
"filename": "RELATIVE_IMAGE_FILE_REFERENCE",
"frame_width": int,
"frame_height": int
},
"name": "UNIQUE_SPRITE_NAME",
"width": int,
"height": int,
"speed": int,
"loop": boolean,
"loopReverse": boolean,
"frames": [
int
]
}
```
* `frames` references the frame indexes in the spritesheet that should be used for this animation. Spritesheets are counted from the top left corner going to the right according to the spritesheet `frame_width` and `frame_height`.
* `loop` says whether or not we should loop the animation
* `loopReverse` says whether or not we should "bounce" the animation (when we reach the end of the frames, start counting back to the beginning, then count to the end, etc). Otherwise the frames are displayed from 0..n and then cycles back to 0.
* `speed` is the number of milliseconds each frame in the animation should appear on the screen
Character files:
```c
{
"name": "UNIQUE_CHARACTER_NAME",
"speedtime": 8,
"speed_x": 0,
"speed_y": 0,
"acceleration_x": 0,
"acceleration_y": 0,
"sprite_mappings": [
{
"state": [
"AKGL_ACTOR_STATE_ALIVE",
"AKGL_ACTOR_STATE_FACE_UP",
"AKGL_ACTOR_STATE_MOVING_UP"
],
"sprite": "menupointer"
}[, ...]
]
}
```
* `speedtime` appears to be legacy and unused.
* `speed_[xy]` and `acceleration_[xy]` are physics parameters that specify the top speed and acceleration rate (in pixels per nanosecond) of the character in physics simulations. The effect of acceleration depends on the physics simulation being used at the time (which may or may not account for gravity, drag, etc).
* `sprite_mappings` map a set of actor state flag bitmasks (assume everything in `state` is `OR`ed together) to a sprite name. The game engine uses this to automatically pick the correct sprite (by name) for a given set of state flags. You need one of these for every possible state the character may be used in.
## How do I load a tilemap from the filesystem and display it on screen with my actors
The engine ONLY supports TilED TMJ tilemaps with tileset external references. Load a tilemap into the global `akgl_Tilemap *gamemap` object.
```c
PASS(e, akgl_tilemap_load(PATHSTRING, gamemap));
```
Actors will be automatically populated from objects in the tilemap object layers. Actor state flags here must be expressed as an integer, you can't (yet) use the same array of strings that is used in character json files.
```json
"objects":[
{
"gid":147,
"height":16,
"id":1,
"name":"player",
"properties":[
{
"name":"character",
"type":"string",
"value":"little guy"
},
{
"name":"state",
"type":"int",
"value":24
}],
"rotation":0,
"type":"actor",
"visible":true,
"width":16,
"x":440.510088317656,
"y":140.347239175702
}[, ... ]
```
Check if the tilemap wants to use its own physics, and if you want to allow that, override the global physics simulation
```c
if ( gamemap->use_own_physics == true ) {
physics = &gamemap->physics;
}
```
Tilemap physics specification follows. A map can specify its own physics properties (drag, gravity) without specifying a custom model.
```json
"properties":[
{
"name":"physics.drag.y",
"type":"float",
"value":0
},
{
"name":"physics.gravity.y",
"type":"float",
"value":0
},
{
"name":"physics.model",
"type":"string",
"value":"arcade"
}],
```
The global `gamemap` object is automatically displayed if it is populated. Actors are drawn at the appropriate map layer depending on the actor's `layer` property (warning: this may be replaced with a `z` property soon.)
## How do I get the screen width and height
The most direct is to call `SDL_GetCurrentDisplayMode` to get the parameters from the returned `SDL_DisplayMode` structure (`->w` and `->h`).
The simplest way is to check the global `camera` object's `camera->w` and `camera->h` object. You may have more than one camera on a scene, and it's theoretically possible that the global camera object has been overriden and no longer represents the full screen.
The most reliable engine-centric way is to use `akgl_get_property` to get the property from the engine. Properties are read and stored as strings, so if you need to do these kinds of things a lot, cache the integer value somewhere.
```c
akgl_String *width = NULL;
int screenwidth = NULL;
PASS(e, akgl_get_property("game.screenwidth", &width, "0"));
PASS(e, aksl_atoi(width->data, &screenwidth));
PASS(e, akgl_heap_release_string(width));
```
