Introduction

Tiled is a simpliest map editor

This is the module for Cerberus-X for using exported maps from Tiled

Requirements

• Cerberus-X

This module requires Cerberus-X modules (mojo and brl)

Installation

Clone this repo in your directory Cerberus-X modules_ext

git clone https://github.com/dzencot/tiled-cerberus-x.git ${CERBERUSDIR}/modules_ext/tiled

Usage

• Create the map in Tiled Editor
• Export map to json

Map

Local tiled = new Tiled()

---

Method ParseJSON(dataLevel:string)

• dataLevel:string - json-file content

---

Method GetWidthMap:Int():Int

---

Method GetHeightMap:Int()

---

Tiles

Method GetIdTile(x:Int, y:Int, nameLayer:String):Int

• x:Int - x-coordinate
• y:Int - y-coordinate
• nameLayer:String - layer

---

Method GetWidthTile:Int():Int

---

Method GetHeightTile:Int():Int

---

Method GetCountLayers:Int():Int

---

Method GetNameLayer:String(index:Int):String

---

Method SetIdTile:Void(x:Int, y:Int, nameLayer:String, idTile:Int)

---

Method RenderTile:Void(idTile:Int, coorX:Int, coorY:Int)

---
