Question

Can drag sources start off already positioned in a drop target?

Hello community - this is my first post!

My question is: When a slide loads, with a drag and drop interaction in it, can the drag sources start off already positioned in a drop target? Below is more explanation of what I am trying to achieve and why.

I have five drag sources

I have two drop targets: drop target A and drop target B.

I would like the drag sources to start already in position (tiled) in drop target A.

In the “Accepted Drag Sources”” window for drop target B, Count is set to 1 and On Accept is set to Replace.

When a user drags a drag source from drop target A onto drop target B my variable is incremented by 1.

When user drags another drag source from drop target A onto drop target B the replaced drag source returns to drop target A and my variable is decremented by 1.

I wouThe advanced actions I can deal with, but I'd be very grateful for any guidance around whether I can start a slide with drag sources already positioned in a drop target. Thank you.

Perhaps I do not fully understand what is being attempted but I was able to create two shapes and make them two distinct drop targets.

I then created four stars of different color and made them all drag sources. I placed two in one target and two in the other layered one on top of the other.

When I previewed the slide I was able to drag them all back and forth from one target to the other target.

So - in this sense - yes, a slide can start with multiple drag sources already inside of it.

Make sure the drag sources are the uppermost layers.

I didn't try to do anything with the actions, though. Perhaps that is the sticking point...?

What am I missing?

What does the variable actually track?

If the value decrements when it is replaced, it doesn't seem to be tracking the quantity of objects on the drop target since a replace condition would be a net change of zero.

Is the variable tracking the particular object and the status of whether it is on that target or not?

There are actually 3 variables that are incremented. Each variable for a counter. I've previously been trying not to overload you guys with info, but I think I should now explain fully!

The user experience I am looking for

On the left you see a list of skills (drag sources). The grey box represents a CV/resume (drop target). On the right hand side are three employers. Each employer is looking for three particular skills. When a skill (drag source) is dropped onto the CV/resume drop target the counter (blue bars) of the employers is increased by one, if the skill dragged on to the CV/resume is one that the employer is looking for. So, dropping "Problem-solving skills" onto the CV/resume will increase the counter (blue bars) of those employers who are looking for problem-solving skills (B & C) by one. The counter (blue bars) of the employer who is not looking for problem-solving skills (A) would not increase. What I am trying to achieve (but have not yet) is that when a skill is replaced (i.e. leaves the CV/resume drop target) the counters decrease by one.

The approach I have taken

Bear in mind I only got my hands on this software about 2 weeks ago so I've probably massively over-engineered the (partial) solution! Any tips/critisism gratefully received!

Variables

The following variables are incremented appropriately when a skill (drag source) is placed on the drop target:

var_emp_a_count
var_emp_b_count
var_emp_c_count

Counters

The counters (blue bars) are obviously, run off the variables. There are ten images for each counter.

One image showing 1 bar
One image showing 2 bars
One image showing three bars
Etc, up to 10 bars (actually I over did this because you can't get to ten with the options!)

All images are initially hidden.

Actions

There are 5 advanced actions - one for each skill:

analy_action
comm_action
lead_action
org_action
prob_action

The only difference between them is that, for example, lead_action increments var_emp_b_count and not the others. prob_action increments var_emp_b_count and var_emp_c_count and not the other, etc.

Details of the actions

Block 1: Increment the appropriate variable

Block 2: Hide all counter images (to wipe out what was showing previously)

Block 3: If var_emp_a_count is equal to 1, show (the blue counter image with 1 level on the counter)), else continue

Block 4: If var_emp_b_count is equal to 1, show (the blue counter image with 1 level on the counter)), else continue

Block 5: If var_emp_c_count is equal to 1, show (the blue counter image with 1 level on the counter)), else continue

All blocks from 6-32(!) do the same, but "is equal to X" and show "image X", as appropriate

Second drop target

What I haven't mentioned here (and actually haven't done yet) is the possible second drop target which the skills (drag sources) would possibly start off in.
