dragdata.setIcon

[Talador]

I am trying to understand how the Action Scripts in the 4e ruleset are working. I´ve got a question regarding the function "encodeActionForDrag(draginfo, rSource, sType, rRolls, rCustom)" inside scripts/manager_actions.lua .
As far as I understand, the function is called (among others) when somebody drags an field which contains an action.
The statement "draginfo.setIcon(aActionIcons[sType]);" should render a graphic at the mouse cursor. For example the icon "graphics\icons\action_roll.png". But everytime I drag a field towards the chatbox I only see a dice...
The function and the statement are both definetly called.

function encodeActionForDrag(draginfo, rSource, sType, rRolls, rCustom)
	draginfo.setType(sType);
	
	if aActionIcons[sType] then
		draginfo.setIcon(aActionIcons[sType]);
	end
	if #rRolls == 1 then
		draginfo.setDescription(rRolls[1].sDesc);
	end
	
	draginfo.setSlot(1);
	draginfo.setNumberData(#rRolls);
	if rSource then
		if rSource.sCTNode ~= "" then
			draginfo.setShortcutData("combattracker_entry", rSource.sCTNode);
		elseif rSource.sCreatureNode ~= "" then
			if rSource.sType == "pc" then
				draginfo.setShortcutData("charsheet", rSource.sCreatureNode);
			elseif rSource.sType == "npc" then
				draginfo.setShortcutData("npc", rSource.sCreatureNode);
			end
		end
	end
	
	local nStart = 1;
	for kRoll, vRoll in ipairs(rRolls) do
		draginfo.setSlot(kRoll + nStart);

		draginfo.setStringData(vRoll.sDesc);
		draginfo.setDieList(vRoll.aDice);
		draginfo.setNumberData(vRoll.nMod);
	end

	if rCustom then
		nStart = nStart + #rRolls;
		for kCustom, vCustom in ipairs(rCustom) do
			draginfo.setSlot(kCustom + nStart);

			draginfo.setStringData(vCustom.sDesc or "");
			draginfo.setDieList(vCustom.aDice or {});
			draginfo.setNumberData(vCustom.nMod or 0);
			draginfo.setShortcutData(vCustom.sClass or "", vCustom.sRecord or "");
		end
	end
end

What am I missing?
Maybe I missunderstood how dragdata.setIcon() works...
Any help?

The string used in dragData.setIcon is not the path/filename it is "The name of an icon resource used for the icon". An icon resource is a reference name that FG uses (which then points to the actual graphics file). For 4e I believe these are in the ruleset in the \graphics\graphics_misc.xml file, search for the "<!-- Action icons for dragging -->" section. This will list the icon "name" you can use, such as "action_roll", "action_attack", etc.

Thank you for your help!
That code is not from me. It is from the 4e ruleset. The icons are in the *.pac and bound in in the code.
Why can I not see the icons when using the ruleset? Ever action event in the 4e ruleset should render an "action_icon" on drag and drop events. But that does not happen. Only a dice is rendered...

The dragdata object has a display prioritization specified by the FG client. (Dice -> Icon -> Token -> String -> Number)

Dice will be rendered if dice are going to be rolled.

To see examples of the action icons in use open the default "Second Wind" power, click the "sword" icon to the right of the power heading to show the healing and "DEF:2" effect. Click-and-drag either of these and you will see a action_heal icon for dragging "1[HSV]" or the the action_effect icon for dragging "DEF:2".

If you have a power that just does the same damage each time (no dice being rolled) you'd see the action_damage icon when being dragged. However, if there are any dice in the damage entry then you would see the dice when dragging.
