Reply To: Can we randomize time with newTimer() ?

Hi Larissa,

If you want the totality of your trial to be 3800ms (because timer-RT = 1700ms, max timer-D1 = 1600ms, timer_cue_D2 = 100ms and timer_D3 = 400ms) start the timer at the beginning of the trial, and wait for it at the end:

Template("tabela-target.csv" , row => 
  newTrial("trial_2_center_cue_UP",
    defaultText
        .center()
        .cssContainer({"position": "absolute",
                       "top": "50%",
                       "left": "50%",
                       "transform": "translate(-50%, +50%)"})
        .print()
    ,
    newTimer("wait-separacao",3800).start()
    ,
    newText("D1", "<br><b>+</b>")
        .cssContainer({"font-size":"100px",
                       "color":"blue"})
        .center()
        .print()
    ,
    newTimer("timer-D1",400+Math.round(1200*Math.random())) // if you want between 400ms and 1600ms, you need 400+[0--1200]
        .start()
        .wait()
    ,
    getText("D1").remove()
    ,
    newText("cue", "<br> <b>*</b>")
       .cssContainer({"font-size":"100px",
                      "color":"green"})
       .center()
       .print()
    ,
    newTimer("timer_cue_D2",100)
        .start()
        .wait()
    ,
    getText("cue","D2").remove()
    ,
    newText("D3", "<br> <b>+</b>")
       .cssContainer({"font-size":"100px",
                      "color":"pink"})
       .center()
       .print()
    ,
    newTimer("timer_D3",400)
        .start()
        .wait()
    ,
    getText("D3").remove()
    ,
    newTimer("timer-RT",1700).start()
    ,
    newImage("imagens", row.imagem).size(500, 200)
    ,
    newText("cruz_central", "<br> <b>+</b>")
        .cssContainer({"font-size":"100px",
                       "color":"black"})
        .center()
        .print()
    ,
    //para cima//
    newCanvas("center", 150,150)
        .add( "center at 50%" , "center at 50%" , getImage("imagens"))
        .cssContainer({"position": "absolute",
                       "margin-top": "85px"})
        .center()
        .log()
        .print()
    ,
    newKey("keypress1","SK")
        .log()
        .callback( getTimer("timer-RT").stop() )
    ,
    getTimer("timer-RT").wait()
    ,
    getKey("keypress1").disable(),
    getText("cruz_central"),
    getCanvas("center").remove()
    ,
    newText("separacao", "<br> <b>+</b>")
        .cssContainer({"font-size":"100px",
                       "color":"yellow"})
        .center()
        .print()
    ,
    getTimer("wait-separacao").wait()
  )
  .log("imagens", row.imagem)
  .log("item", row.versao)
);

Also, re. the feedback on each trial, just use the Var named localRT to set a Text element in the success/failure commands. For example, in success:

newVar("positiveFeedbackText").set( getVar("localRT") ).set( v => "Correct! Your speed was: "+v+"ms!" )
,
newText("positiveFeedback").text( getVar("positiveFeedbackText") ).print()
