Level JSON file structure

Example of 2 layer level (with 2 different animations and 3 events) exported to JSON file:

(Actual key-value expressions may be arranged in different order than stated below, however, this does not affect data integrity, and the JSON file will always be correct.)

{  
  "level-name": "Level 1",  
  "tile-sizeX": 32,   
  "tile-sizeY": 32,  
  "animations": [ 
    {"fps": 15, "is-ping-pong": false, "frames": [1, 2, 3, 4]},

JSON keys meaning:

• level-name - String containing level name
• tile-sizeX, tile-sizeY - Tile dimensions in pixels
• animations - List (array) of all animations
  • fps - Frames per second value
  • is-ping-pong - Boolean describint whether animation is ping-pong type
  • frames - Array containing tile indexes corresponding to each frame of animation
• layers - List (array) of all layers
  • sizeX, SizeY - layers dimensions in tiles
  • tiles - 2D array representing indexes of tiles on each position

[[x0y0, x1y0, x2y0],  
[x0y1, x1y1, x2y1],  
[x0y2, x1y2, x2y2]]

(value < 0 corresponds to animation index, value >= 0 corresponds to tile index)

• events - List (array) of all events
  • name - String containing event name
  • parameters - String containing event custom parameters
  • level-positions - 2D array containing list of current event's [x,y] positions on the map
