I have coded my experiment with correct/valid responses being keyboard inputs but would now like to change it to mouse input (left and right mouse click) instead.
So what I had was (among other code of course):
<values>
/ reference_odor_item = 0
/ comparison_odor_item = 0
/ odor_1_item = 0
/ odor_2_item = 0
/ is_reference = ""
/ correctkey = 0
</values>
<trial discrimination>
/ ontrialbegin = [
values.reference_odor_item = list.reference_odors.nextvalue;
values.comparison_odor_item = list.comparison_odors.nextvalue;
values.is_reference = list.is_reference_list.nextvalue;
]
/ ontrialbegin = [
if (values.is_reference == "odor_1") {
values.odor_1_item = values.reference_odor_item;
values.odor_2_item = values.comparison_odor_item;
values.correctkey = lbuttondown;
} else if (values.is_reference == "odor_2") {
values.odor_1_item = values.comparison_odor_item;
values.odor_2_item = values.reference_odor_item;
values.correctkey = 38;
};
]
/ stimulustimes = [0=3; 1000=2; 2000=1; 2850=reference_odor; 3000=inhale; 3000=reference_label; 5000=empty;
7000=3; 8000=2; 9000=1; 9850=odor_1; 10000=inhale; 10000=odor1_label; 12000=empty;
14000=3; 15000=2; 16000=1; 16850=odor_2; 17000=inhale; 17000=odor2_label; 19000=empty;
21000=odor1_response; 21000=odor2_response; 21000=discrim_quest]
/ validresponse = (30, 38)
/ beginresponsetime = 21000
/ pretrialpause = 1000
/ iscorrectresponse = [
trial.discrimination.response == values.correctmouseevent
]
</trial>
I now did the following changes (see what is printed bold):
<values>
/ reference_odor_item = 0
/ comparison_odor_item = 0
/ odor_1_item = 0
/ odor_2_item = 0
/ is_reference = ""
/ correctmouseevent = rbuttondown
</values>
<trial discrimination>
/ ontrialbegin = [
values.reference_odor_item = list.reference_odors.nextvalue;
values.comparison_odor_item = list.comparison_odors.nextvalue;
values.is_reference = list.is_reference_list.nextvalue;
]
/ ontrialbegin = [
if (values.is_reference == "odor_1") {
values.odor_1_item = values.reference_odor_item;
values.odor_2_item = values.comparison_odor_item;
values.correctmouseevent = lbuttondown;
} else if (values.is_reference == "odor_2") {
values.odor_1_item = values.comparison_odor_item;
values.odor_2_item = values.reference_odor_item;
values.correctmouseevent = rbuttondown;
};
]
/ stimulustimes = [0=3; 1000=2; 2000=1; 2850=reference_odor; 3000=inhale; 3000=reference_label; 5000=empty;
7000=3; 8000=2; 9000=1; 9850=odor_1; 10000=inhale; 10000=odor1_label; 12000=empty;
14000=3; 15000=2; 16000=1; 16850=odor_2; 17000=inhale; 17000=odor2_label; 19000=empty;
21000=odor1_response; 21000=odor2_response; 21000=discrim_quest]
/ validresponse = (lbuttondown, rbuttondown)
/ inputdevice = mousekey
/ beginresponsetime = 21000
/ pretrialpause = 1000
/ iscorrectresponse = [
trial.discrimination.response == values.correctmouseevent
]
</trial>
The only error that I now still get is that the 'lbuttondown' expression within the if - else if expression in /ontrialbegin (the one I colored red) "contains an unknown element or property name." I suppose this is the case because Inquisit does not know, on trial begin, that the input device has changed from its default. I was, thus, wondering how this can be communicated to Inquisit or whether I am wrong and something else needs to be changed about my code.
Thousand thanks in advance!

I of course meant values.correctkey = 30 within the code that I first had and not values.correctkey = lbuttondown, as it says now.
Sorry about that!

You need double quotes:
<values>
/ reference_odor_item = 0
/ comparison_odor_item = 0
/ odor_1_item = 0
/ odor_2_item = 0
/ is_reference = ""
/ correctmouseevent = "rbuttondown"
</values>
<trial discrimination>
/ ontrialbegin = [
values.reference_odor_item = list.reference_odors.nextvalue;
values.comparison_odor_item = list.comparison_odors.nextvalue;
values.is_reference = list.is_reference_list.nextvalue;
]
/ ontrialbegin = [
if (values.is_reference == "odor_1") {
values.odor_1_item = values.reference_odor_item;
values.odor_2_item = values.comparison_odor_item;
values.correctmouseevent = "lbuttondown";
} else if (values.is_reference == "odor_2") {
values.odor_1_item = values.comparison_odor_item;
values.odor_2_item = values.reference_odor_item;
values.correctmouseevent = "rbuttondown";
};
