javascript - How to skew a tiled map in canvasengine -

i use canvasengine program html5 game. have implemented tiled map works far, static.

now want player have ability move around. thought: "ok, use canvasengine skew command". works:

canvas.scene.new ({ name: "tutorial", materials: {     images: {         dg_edging232: "/maps/tilesets/dg_edging232.gif"     } }, ready: function(stage) {      this.el = this.createelement();     var tiled = canvas.tiled.new ();     tiled.load(this, this.el, "/maps/tutorial.json");     tiled.ready(function() {         var tile_w = this.gettilewidth(),                 tile_h = this.gettileheight(),                 layer_object = this.getlayerobject();         stage.append(this.el);     });    }, render: function(stage) {     canvas.input.keydown(input.left);     canvas.input.keydown(input.right);     canvas.input.keydown(input.up);     canvas.input.keydown(input.down);       stage.refresh(); } }); 

now, i'd this:

canvas.input.keydown(input.left,this.el.x--); 

but can't work syntax above.

never worked libarary, looks might want move keydown calls have in render ready, , on render, test whether key pressed , move sprite accordingly.

ready: function () {   // ... ready code    // it's not clear docs, appears need call   // keydown each input register it, if you're passing no callbacks.   // however, i'm guessing here.  may not necessary.   canvas.input.keydown(input.left);   // ... , on each direction },  render: function () {   // every frame test if key down, , update sprite accordingly   if (canvas.input.ispressed(input.left)) this.el.x--;   // ... , on each direction    stage.refresh(); }
