### ActionScript: Define Collision Polygons and Paths from Tiled Objects

Source: https://context7.com/arkeus/as3-tiled-reader/llms.txt

This ActionScript example demonstrates how to process Tiled objects with polygon and polyline shapes to define collision boundaries or navigation paths. It utilizes the io.arkeus.tiled library and flash.geom.Point for coordinate manipulation.

```actionscript
package {
    import flash.geom.Point;
    import io.arkeus.tiled.TiledObject;
    import io.arkeus.tiled.TiledObjectLayer;

    public class PathfindingSystem {
        public function setupCollisionPolygons(objectLayer:TiledObjectLayer):void {
            var collisions:Vector.<TiledObject> = objectLayer.getObjectsByType("collision");

            for each (var obj:TiledObject in collisions) {
                if (obj.shape == TiledObject.POLYGON) {
                    trace("Collision polygon: " + obj.name);
                    var points:Vector.<Point> = obj.points;

                    // Create collision shape from points
                    for (var i:int = 0; i < points.length; i++) {
                        var worldX:Number = obj.x + points[i].x;
                        var worldY:Number = obj.y + points[i].y;
                        trace("  Point " + i + ": (" + worldX + ", " + worldY + ")");
                    }

                    createCollisionPolygon(obj.x, obj.y, points);

                } else if (obj.shape == TiledObject.POLYLINE) {
                    trace("Path: " + obj.name);
                    var pathPoints:Vector.<Point> = obj.points;

                    // Create patrol path or navigation path
                    createPath(obj.x, obj.y, pathPoints);
                }
            }
        }

        private function createCollisionPolygon(offsetX:Number, offsetY:Number, points:Vector.<Point>):void {
            // Collision polygon creation
        }

        private function createPath(offsetX:Number, offsetY:Number, points:Vector.<Point>):void {
            // Path creation for AI or player movement
        }
    }
}

                }

                // Get all objects of a specific type
                var enemies:Vector.<TiledObject> = objectLayer.getObjectsByType("enemy");
                if (enemies) {
                    for each (var enemy:TiledObject in enemies) {
                        trace("Enemy: " + enemy.name + " at " + enemy.x + ", " + enemy.y);
                        trace("Size: " + enemy.width + "x" + enemy.height);

                        // Check object shape
                        if (enemy.shape == TiledObject.RECTANGLE) {

### Accessing Tileset Information in ActionScript 3

Source: https://context7.com/arkeus/as3-tiled-reader/llms.txt

This snippet demonstrates how to access and display metadata for tilesets within a Tiled map. It iterates through all tilesets, extracts properties like dimensions, spacing, and offset, and also accesses custom properties defined for individual tiles. Dependencies include the io.arkeus.tiled library.

```actionscript
package {
    import io.arkeus.tiled.TiledMap;
    import io.arkeus.tiled.TiledTileset;
    import io.arkeus.tiled.TiledTile;
    import flash.display.Bitmap;
    import flash.display.BitmapData;
    import flash.geom.Rectangle;

    public class TilesetManager {
        private var tilesetBitmaps:Object = {};

        public function loadTilesets(map:TiledMap):void {
            // Iterate through all tilesets
            for (var i:int = 0; i < map.tilesets.length; i++) {
                var tileset:TiledTileset = map.tilesets.getTilesetByIndex(i);

                trace("Tileset: " + tileset.name);
                trace("First GID: " + tileset.firstGid);
                trace("Tile size: " + tileset.tileWidth + "x" + tileset.tileHeight);
                trace("Spacing: " + tileset.spacing);
                trace("Margin: " + tileset.margin);
                trace("Offset: " + tileset.tileOffset.x + ", " + tileset.tileOffset.y);

                trace("Image source: " + tileset.image.source);
                trace("Image size: " + tileset.image.width + "x" + tileset.image.height);

                // Access custom tile properties
                for (var tileId:String in tileset.tiles) {
                    var tile:TiledTile = tileset.tiles[tileId];
                    trace("  Tile ID " + tile.id + " properties:");

                    var animated:String = tile.properties.get("animated");

                    if (damage) trace("    Damage: " + damage);
                }
            }
        }

        public function getTileImage(map:TiledMap, gid:int):BitmapData {
            // Find tileset for this GID
            var tileset:TiledTileset = map.tilesets.getTilesetByGid(gid);
            if (!tileset) return null;

            // Calculate tile position in tileset
            var localId:int = gid - tileset.firstGid;
            var tilesPerRow:int = (tileset.image.width - tileset.margin * 2 + tileset.spacing) /
                                   (tileset.tileWidth + tileset.spacing);

            var tileX:int = localId % tilesPerRow;
            var tileY:int = localId / tilesPerRow;

            var sourceX:int = tileset.margin + tileX * (tileset.tileWidth + tileset.spacing);
            var sourceY:int = tileset.margin + tileY * (tileset.tileHeight + tileset.spacing);

            // Extract tile from tileset bitmap (implementation-specific)
            return extractTile(tileset.name, sourceX, sourceY, tileset.tileWidth, tileset.tileHeight);
        }

        private function extractTile(tilesetName:String, x:int, y:int, w:int, h:int):BitmapData {
            // Extract tile bitmap implementation
            return null;
        }
    }

### Rendering Image Layers in ActionScript 3

Source: https://context7.com/arkeus/as3-tiled-reader/llms.txt

This ActionScript 3 code demonstrates how to iterate through map layers and render image layers. It accesses layer properties such as name, opacity, and visibility, then proceeds to load and display the associated image using Flash's Loader class. This is useful for parallax backgrounds or static overlays.

```actionscript
package {
    import io.arkeus.tiled.TiledMap;
    import io.arkeus.tiled.TiledImageLayer;
    import io.arkeus.tiled.TiledLayer;
    import flash.display.Loader;
    import flash.net.URLRequest;

    public class ImageLayerRenderer {
        public function renderImageLayers(map:TiledMap):void {
            var allLayers:Vector.<TiledLayer> = map.layers.getAllLayers();

            for each (var layer:TiledLayer in allLayers) {
                if (layer is TiledImageLayer) {
                    var imageLayer:TiledImageLayer = layer as TiledImageLayer;

                    trace("Image layer: " + imageLayer.name);
                    trace("Opacity: " + imageLayer.opacity);
                    trace("Visible: " + imageLayer.visible);

                    // Load and display image
                    var imagePath:String = imageLayer.image.source;
                    var imageWidth:int = imageLayer.image.width;
                    var imageHeight:int = imageLayer.image.height;

                    trace("Loading image: " + imagePath);
                    trace("Image dimensions: " + imageWidth + "x" + imageHeight);

                    loadAndDisplayImage(imagePath, imageLayer.opacity, imageLayer.visible);
                }
            }
        }

        private function loadAndDisplayImage(path:String, opacity:Number, visible:Boolean):void {
            if (!visible) return;

            var loader:Loader = new Loader();
            loader.alpha = opacity;
            loader.load(new URLRequest(path));
            // Add to display list...
        }
    }
}

### Load TMX Map from Embedded Resource (ActionScript 3)

Source: https://context7.com/arkeus/as3-tiled-reader/llms.txt

Loads an embedded TMX map file directly within a Flash application. This method uses the [Embed] metadata tag to include the TMX file as a resource. It requires the TiledReader and TiledMap classes from the AS3 Tiled Reader library. The loaded map can then be accessed for its properties like size, tile dimensions, orientation, and layers.

```actionscript
package {
    import flash.display.Sprite;
    import io.arkeus.tiled.TiledReader;
    import io.arkeus.tiled.TiledMap;

    public class GameWorld extends Sprite {
        [Embed(source = "/maps/level1.tmx", mimeType = "application/octet-stream")]
        public static const LEVEL_1:Class;

        private var map:TiledMap;

        public function GameWorld() {
            // Load and parse the embedded map
            var reader:TiledReader = new TiledReader();
            map = reader.loadFromEmbedded(LEVEL_1);

            // Access map properties
            trace("Map size: " + map.width + "x" + map.height);
            trace("Tile size: " + map.tileWidth + "x" + map.tileHeight);
            trace("Orientation: " + map.orientation);
            trace("Background: #" + map.backgroundColor.toString(16));
            trace("Total layers: " + map.layers.length);
        }
    }
}
```

### Read Custom Properties from Tiled Maps, Layers, and Objects

Source: https://context7.com/arkeus/as3-tiled-reader/llms.txt

This ActionScript code demonstrates how to read custom properties defined on Tiled maps, layers, and objects. It accesses key-value pairs stored in TiledProperties for metadata like music tracks, ambient light, parallax scrolling, auto-scroll speeds, and game object attributes such as health and AI type. This snippet requires the io.arkeus.tiled library.

```actionscript

            var props:TiledProperties = map.properties;
            var musicTrack:String = props.get("music");
            var ambientLight:String = props.get("ambient_light");
            var weatherEffect:String = props.get("weather");

            trace("Map music: " + musicTrack);
            trace("Ambient light: " + ambientLight);
            trace("Weather: " + weatherEffect);

            // Layer properties
            var layers:Vector.<TiledLayer> = map.layers.getAllLayers();
            for each (var layer:TiledLayer in layers) {
                var layerProps:TiledProperties = layer.properties;
                var parallaxX:String = layerProps.get("parallax_x");
                var parallaxY:String = layerProps.get("parallax_y");
                var scrollSpeed:String = layerProps.get("scroll_speed");

                if (parallaxX) {
                    trace(layer.name + " parallax: " + parallaxX + ", " + parallaxY);
                    setLayerParallax(layer, parseFloat(parallaxX), parseFloat(parallaxY));
                }

                if (scrollSpeed) {
                    trace(layer.name + " auto-scroll: " + scrollSpeed);
                    setLayerScrollSpeed(layer, parseFloat(scrollSpeed));

### Load TMX Map from XML in AS3

Source: https://github.com/arkeus/as3-tiled-reader/blob/master/README.md

Loads and parses TMX map data directly from an XML object using the TiledReader class. This method is useful when the TMX data is loaded externally or generated dynamically.

```actionscript
var reader:TiledReader = new TiledReader;
var map:TiledMap = reader.loadFromXML(yourXmlObject);
```

### Access Tile Layer Data (ActionScript 3)

Source: https://context7.com/arkeus/as3-tiled-reader/llms.txt

Provides methods to access and iterate through tile data within a TiledMap object. It retrieves all tile layers using map.layers.getTileLayers() and then iterates through each layer's 2D data array. Information such as layer name, visibility, opacity, encoding, and compression can be inspected. The global tile ID (GID) is used to identify and potentially render individual tiles.

```actionscript
package {
    import io.arkeus.tiled.TiledMap;
    import io.arkeus.tiled.TiledTileLayer;
    import io.arkeus.tiled.TiledLayer;

    public class TileRenderer {
        public function renderMap(map:TiledMap):void {
            // Get all tile layers
            var tileLayers:Vector.<TiledLayer> = map.layers.getTileLayers();

            for each (var layer:TiledLayer in tileLayers) {
                var tileLayer:TiledTileLayer = layer as TiledTileLayer;

                trace("Layer: " + tileLayer.name);
                trace("Visible: " + tileLayer.visible);
                trace("Opacity: " + tileLayer.opacity);
                trace("Encoding: " + tileLayer.encoding);
                trace("Compression: " + tileLayer.compression);

                // Access tile data (2D array)
                var data:Array = tileLayer.data;
                for (var y:int = 0; y < tileLayer.height; y++) {
                    for (var x:int = 0; x < tileLayer.width; x++) {
                        var tileGid:int = data[y][x];
                        if (tileGid > 0) {
                            // Render tile at position (x, y) using global tile ID
                            renderTile(x, y, tileGid);
                        }
                    }
                }
            }
        }

        private function renderTile(x:int, y:int, gid:int):void {
            // Implementation for rendering individual tiles
        }
    }
}
```

### Load Embedded TMX Map in AS3

Source: https://github.com/arkeus/as3-tiled-reader/blob/master/README.md

Loads and parses an embedded TMX map file using the TiledReader class. The parsed map data is returned as a TiledMap object, which can then be used to access map elements.

```actionscript
var reader:TiledReader = new TiledReader;
var map:TiledMap = reader.loadFromEmbedded(WORLD);
```

### Filter and Access Tiled Layers by Type and Visibility

Source: https://context7.com/arkeus/as3-tiled-reader/llms.txt

This ActionScript code demonstrates how to filter Tiled layers based on their visibility and type (tile layers, object layers). It also shows how to access custom properties defined on layers, such as 'type' and 'z-index', and conditionally process specific layer types like collision layers. This snippet requires the io.arkeus.tiled library.

```actionscript
package {
    import io.arkeus.tiled.TiledMap;
    import io.arkeus.tiled.TiledLayer;
    import io.arkeus.tiled.TiledTileLayer;

    public class LayerManager {
        public function processLayers(map:TiledMap):void {
            // Get only visible layers
            var visibleLayers:Vector.<TiledLayer> = map.layers.getVisibleLayers();
            trace("Visible layers: " + visibleLayers.length);

            for each (var layer:TiledLayer in visibleLayers) {
                trace("  " + layer.name + " (opacity: " + layer.opacity + ")");

                // Access layer-specific properties
                var layerType:String = layer.properties.get("type");
                var zIndex:String = layer.properties.get("z-index");

                if (layerType == "collision") {
                    processCollisionLayer(layer as TiledTileLayer);
                }
            }

            // Get all layers in render order (bottom to top)
            var allLayers:Vector.<TiledLayer> = map.layers.getAllLayers();
            for (var i:int = 0; i < allLayers.length; i++) {
                trace("Layer " + i + ": " + allLayers[i].name);
            }

            // Get only tile layers
            var tileLayers:Vector.<TiledLayer> = map.layers.getTileLayers();
            trace("Tile layers: " + tileLayers.length);

            // Get only object layers
            var objectLayers:Vector.<TiledLayer> = map.layers.getObjectLayers();
            trace("Object layers: " + objectLayers.length);
        }

        private function processCollisionLayer(layer:TiledTileLayer):void {
            // Process collision tiles
        }
    }
}
```

### Embed TMX File in AS3

Source: https://github.com/arkeus/as3-tiled-reader/blob/master/README.md

Embeds a TMX map file directly into your ActionScript 3 application. This allows the map data to be compiled with your application, making it available at runtime.

```actionscript
[Embed(source = "/map/world.tmx", mimeType = "application/octet-stream")]
public static const WORLD:Class;
```
