  • Corona Sprites – hvordan virker de?

    At skabe en sprite i Gimp eller Photoshop er relativt enkelt. Beslut dig for, hvor stor hver frame skal være, fx 512 x 256 px. I Photoshop skabes et dokument, med plads til fx 8 billeder. Koden herunder viser, hvordan animationen fungerer.

    • local sheetData – her oplysninger om png filens størrelse.
    • width = frame-bredde.
    • height = frame-højde.
    • sheetContentWidth og -Height: størrelsen på hele .png filen

    Når Corona har disse oplysninger kan animationen afvikles. Animationen initieres med andre ord af koden. Se eksemplet fra Coronas side om sprites.

    local sheetData = { width=512, height=256, numFrames=8, sheetContentWidth=1024, sheetContentHeight=1024 }

local mySheet = graphics.newImageSheet( "runningcat.png", sheetData )

local sequenceData = {
{ name = "normalRun", start=1, count=8, time=800 },
{ name = "fastRun", frames={ 1,2,4,5,6,7 }, time=250 }
}

local animation = display.newSprite( mySheet, sequenceData )
animation.x = display.contentWidth/2 --center the sprite horizontally
animation.y = display.contentHeight/2 --center the sprite vertically

animation:play()

  • WordPress and jQuery

    Add this code to the header.php file in the theme. Add this line before wp_head():

    wp_enqueue_script("jquery");

    Then you can write a script (inside script tags) – somewhat like this:

    var $j = jQuery.noConflict(); // using j as selector to avoid conflicts

$j(function(){

    $j("#respond").hide(); // hide comment field

});

    Based on this tutorial by Chris Coyier.

  • Photoshop Happens

    Has Photoshop gone too far? 
    Right now the debate is red hot in the international media. Some even suggest a ban on Photoshop. On the other hand: retouching is as old as the history of photography. Or even painting – not all portraits are completely honest.

    Debate on CNN
    On CNN the model protest against the photoshop rendering. She cannot live up to the picture that the photoshop wizard conjures up.

    Here is a method where you can control a movie inside another movie. The strange beast on the top left has a dice face. It’s the same movie as the dice rolling. So by changing the frame you can control fairly complex animations.


    /*
    FACIAL EXPRESSIONS
    How to control a movie inside another movie.
    In a keyframe try the following:
    */

    addEventListener(Event.ENTER_FRAME,faceshift);
    function faceshift(event:Event) {
    kitty.kFace.gotoAndStop(3); // stops at face 3
    }

    The trick is in this codeline:

    • kitty.kFace.gotoAndStop(3);

    Here you control a movie inside another movie. So on the stage you see a kitty. Inside kitty is a movieclip named kFace. By gotoAndStop / Play you can control animations like facial expressions and similar.

    Tip: use onEnterFrame or buttons in order to control the movies.
