Hi! I need some help with pathfinder written in phaser and easystar. I'm not too experienced with it, but I trying mix it togather :> Look at code (sorry for chaos... its my 1000`th attempt .__. ) There is probably one little mistake and it doesnt work :< daaamn map 40x40 tiles: 1,2,3,4 --> acceptable 1 and 4. Thanks! var game = new Phaser.Game(800, 600, Phaser.CANVAS, 'phaser-example', { preload: preload, create: create, update: update, render: render }); var easystar = new EasyStar.js(); var currentCowboyXtile var currentCowboyYtile function preload() { game.load.tilemap('desert', 'img/desert.json', null, Phaser.Tilemap.TILED_JSON);

I wanted to implement pathfinder in my game. I couldnt find any examples in google. Can smeone help me!

So, I'm using both the isometric plugin and the pathfinder plugin in my game. The isometric plugin doesn't use a tilemap to generate the tiles but instead sprites (extended isoSprites). Problem is that the pathfinder plugin needs a tilemap to generate a grid (with walkables and non-walkables) for pathfinding. e.g.: map = map = game.add.tilemap('desert'); pathfinder.setGrid(map.layers[0].data, walkables); Does anyone know of a workaround? Is there a way to convert the isoSprites into a tilemap or, perhaps, extend them further so they can have the layer Member with data (walkable, non-walkable) on each tile? I'm completely new here so forgive me if I'm not using the right terms. I'd be grateful for any help!

Hello all, I'm pretty new on game development and I've chosen Phaser as the framework for our project. We are a Brazilian dev team (to be honest we're just two atm lol). The project home: http://www.in8game.com Blog (Portuguese): http://www.in8game.com/blog/ And tests I'm doing with Phaser: http://www.in8game.com/prototipo/ Well, I've made some tests using the pathfinder plugin and it's cool. I'd like to ask you what do you think would be the better approach to a point and click player movement using the pathfinder. The player will have a "velocity" defined by the "vehicle" he is using atm. Idk if maybe I can add a tween tile by tile using the plugin or if it's better to use some physics here. Hope I made myself understandable. Sorry about my poor English. I'm willing to make something new and cool using Phaser to share with you guys. Thanks in advance. Rainer Lopez

Hello guys, First sorry for my English. I need help for move a sprite in a layer using the plugin ( PathFinder). I can move the sprite, when using the update method. But when I try to create a specific method (MoveSprite) I can not move the sprite. follow the link to view: http://jsbin.com/hutomuqi/3/edit
