05 - Adding an Isometric player that can be moved

Adding Ralph from the vanilla player movement tutorial is easy in JsIso, we also get the ability to take advantage of the height map with no extra work.
In this sample we have added a second layer which could hold NPCs, Pickups, Players, Trees, Pylons, Water Towers, Walls of Winterfell... endless possibilities.

With the new layer "objectLayer" we apply the same properties as the "tileLayer", but we set - heightMapOnTop: true// We want to draw only on top of the heightmap.
This makes all graphics in this layer drawn on top, however for this tutorial we only want to draw Ralph, so we use the tileImageOverwrite property of layer.draw():

 if (i === ralphX && j === ralphY) {
       objectLayer.draw(i, j, ralphGraphic);
 }



As always, check out the live code viewer to fiddle, linked at the bottom:

    function(CanvasControl, TileField, imgLoad, CanvasInput) {

      // RGBA of color to use
      var tileColor = "(158, 154, 255, 1)";
      var groundColor =  "(100, 154, 100, 1)";

      // Our Tile Map

  27. "Een makelaar bemiddelt bij koop en verkoop, huur en verhuur van huizen,
    winkels, horecabedrijven, kantoren, roerende zaken, verzekeringen, op de
    goederentermijnmarkt of ander roerend, onroerend of registergoed, regelt
    contracten en (ver)koopafspraken. Een groot deel van het werk bestaat uit
    het zoeken van (de makelaar van) een geschikte partij om dat bepaalde goed
    eenmalig mee te verhandelen. De makelaar is dus slechts tussenpersoon en
    is werkzaam krachtens een overeenkomst van bemiddeling. Het vak wordt de
    makelaardij genoemd. De makelaar verzorgt traditioneel alle zaken van
    opname tot de overdracht door de notaris. Hiervoor betaalt de klant een
    courtage, dit is een vooraf afgesproken percentage ( meestal tussen 1% en
    2% ) van de uiteindelijk gerealiseerde verkoopprijs. De Nederlandse
    Vereniging van Makelaars (NVM) hanteerde tot eind jaren 90 adviestarieven.
    Dit is door de Nederlandse Mededingingsautoriteit (NMa) verboden.
    Tegenwoordig zijn er ook makelaars, die een vast tarief hanteren ongeacht
    de verkoopwaarde. Zolang de werkzaamheden van de makelaar niet tot
    resultaat leiden, hoeft de verkopende klant meestal alleen de door de
    makelaar gemaakte kosten te vergoeden. Primair is de bemiddeling
    bij verkoop van woningen, appartementen, flat, bedrijfspand en winkels." Makelaarskantoor

  46. A lot of people love the idea of fixing or restoring cars for a living, and for good reason. While extremely satisfying and enjoyable, however, this line of work isn’t without its challenges. Whether you work at a dealership or in a small repair shop, there are certain qualities you need to have or adopt in order to be an efficient and reliable auto mechanic:

    Restoring Old Cars To Their Original Condition

    First of all, you need excellent work ethics. A good car mechanic knows who to trust with a certain job, how to solve problems quickly, and how to be completely honest and transparent when dealing with customers and solving tricky problems.
    Problem solving skills are also a must. Auto mechanics often have to deal with unforeseen problems and work around them to get the job done properly and on time.
    You need very strong technical skills to be able to actually get the job done. This skill can be learned, but a certain level of innate dexterity and proficiency with basic tools should be required even for younger, less experienced aspiring mechanics. They should be versed in hydraulic fittings Denver mechanic shops might require.
    Finally, leadership and communication skills are indispensable. While a good mechanic can work well on his/her own, some jobs require excellent teamwork and coordination, as well as good customer service skills.
