Hi!

I have two set of items (i.e. 'item labelplayer1' and 'item labelplayer2') , I would like to displayed a different pair on each new trial (trial Round), however it keeps repeating the same ones. I guess it's due to the 'currentitem' but I can't find an alternative (e.g. a 'nextitem'). I also tried to set up an /ontrialbegin but as a beginner I didn't manage to do so...

Thanks in advance for your help!!

<trial Round>
/ ontrialbegin = [
values.roundnumber+=1;
]
/ stimulustimes = [0=round]
/ trialduration = 5000
</trial>

<item round>
/ 1 = "Trial <%values.roundnumber%> is about to start.

You have been paired with Player <%text.avatar1_round.currentitem%> and Player <%text.avatar2_round.currentitem%> "
</item>

<text Round>
/ position = (50%,50%)
/ items = round
/ size = (60%,10%)
/ vjustify = center
/ fontstyle = ("Arial", 3%, false, false, false, false, 5, 1)
</text>

<text avatar1_round>
/ items = labelplayer1
/ fontstyle = ("Arial", 3%, true)
/ position = (29, 30)
</text>

<text avatar2_round>
/ items = labelplayer2
/ fontstyle = ("Arial", 3%, true)
/ position = (71, 30)
</text>

<item labelplayer1>
/1 = "McAdams"

</item>

Nothing in your code performs any selection on <text avatar1_round> and <text avatar2_round>, so there is nothing that could change the current item for either.

You can do

<values>
/ roundnumber = 0
</values>

<block example>
/ trials = [1-4 = Round]
</block>

<trial Round>
/ ontrialbegin = [
values.roundnumber+=1;
]
/ stimulustimes = [0=round]
/ trialduration = 5000
</trial>

<item round>
/ 1 = "Trial <%values.roundnumber%> is about to start.

You have been paired with Player <%item.labelplayer1.item(text.avatar1_round.nextindex)%> and Player <%item.labelplayer2.item(text.avatar2_round.nextindex)%> "
</item>

<text Round>
/ position = (50%,50%)
/ items = round
/ size = (60%,10%)
/ vjustify = center
/ fontstyle = ("Arial", 3%, false, false, false, false, 5, 1)
</text>

<text avatar1_round>
/ items = labelplayer1
/ fontstyle = ("Arial", 3%, true)
/ position = (29, 30)
</text>

<text avatar2_round>
/ items = labelplayer2
/ fontstyle = ("Arial", 3%, true)
/ position = (71, 30)
</text>

<item labelplayer1>
/1 = "McAdams"
/2 = "Atkinson"
/3 = "Bedward"
/4 = "Cuddy"
/5 = "Pappas"
/6 = "Tembo"
/7 = "Dunlop"
/8 = "Cleary"
/9 = "Gant"
/10 = "Watkins"
/11 = "Fleming"
/12 = "Conway"
/13 = "Matson"
/14 = "Stevenson"
/15 = "Farley"
/16 = "Osullivan"
</item>

<item labelplayer2>
/1 = "Angus2"
/2 = "Benson2"
/3 = "Jenkins2"
/4 = "Sherman2"
/5 = "Pappas2"
/6 = "Tembo2"
/7 = "Dunlop2"
/8 = "Cleary2"
/9 = "Gant2"
/10 = "Watkins2"
/11 = "Fleming2"
/12 = "Conway2"
