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

Dear Jeremy, I was able to take steps a and b, but I’m struggling with step c:

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()
,
    newText("D1", "<br><b>+</b>")
    .cssContainer({
    "font-size":"100px",
    "color":"blue"})
    .center()
    .print()
,
   newTimer("timer-D1",1000+Math.round(1600*Math.random())) // ------------------------------> my new random time between 400 and 1600 ms
    .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) // <-------------------------------------------- my new RT trial which imposes the answer within 1700 ms
    .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>") // <------------------------- this should be 3500 ms - timer-RT - timer-D1
   .cssContainer({
    "font-size":"100px",
    "color":"yellow"})
   .center()
   .print()
,
    newTimer("wait-separacao",2500)
    .start()
    .wait()
)
  .log("imagens", row.imagem)
  .log("item", row.versao)
);

I don’t see how putting “wait separação” before D1 would make it be: WAIT SEPARAÇÃO = 3500 MINUS timer-RT MINUS timer-D1 . Would you mind explaining it again, please?

Thanks in advance, as always!
