Dice rolling, with dice...

[celestian]

So this is probably something I'm just missing that's simple. I'm trying to roll 2d6 and 2d4 and get the result. The dice roll and a result shows in chat but... I can't programmatically get the value of the rolled result. Here is how I do the rolls. (I've tried performAction and actionDirect).

local rTurnHDRoll = { sType = "dice", sDesc = "Turn Undead", aDice = aTurnDice, nMod = 0 };
--ActionsManager.performAction(nil, nil, rTurnHDRoll);
ActionsManager.actionDirect(nil, "dice", { rTurnHDRoll });

When I view rTurnHDRoll in debug

Debug.console("manager_action_turnundead.lua","onRoll","rTurnHDRoll",rTurnHDRoll);

I see...

Runtime Notice: s'manager_action_turnundead.lua' | s'onRoll' | s'rTurnHDRoll' | { s'sType' = s'dice', s'aDice' = { #1 = s'd6', #2 = s'd6', #3 = s'd4', #4 = s'd4' }, s'nMod' = #0, s'sDesc' = s'Turn Undead' }

You'll notice there is not a "result = #SomeNumber" there. What I want to do is make those rolls and get the value. I've reviewed various functions that do rolls and use rRoll style and they all seem to get a "result" key in the end run...

Is there a another function I'm missing that will do this? I can write something to do this but surely I'm just blind?

That debug looks like no results are available - individual dice nor the total result. Where do you have the debug code? You’ll need to look in the final result handler in a different function to where you call the actionDirect function. Rolling is asynchronous, FG doesn’t stop a function waiting for the result of the roll, it needs to be looked at in the result handler function.

Trenloe, that is an outstanding post. I agree with Dulux that it should be in the wiki, but I think it needs to be in a "useful forum posts" kind of section that links back to it rather than trying to duplicate posts onto the Wiki.

It's there, it's just in the "code" mode and doesn't wrap.

Runtime Notice: s'manager_action_turnundead.lua' | s'onRoll' | s'rTurnHDRoll' | { s'sType' = s'dice', s'aDice' = { #1 = s'd6', #2 = s'd6', #3 = s'd4', #4 = s'd4' }, s'nMod' = #0, s'sDesc' = s'Turn Undead' }

2d6 and 2d4.

I'll check it out, thanks

So, I've done this before (infact the turn undead does just what you're suggesting) but I don't think I need the onRoll bit unless that hook somehow is setting rRoll.result?

"local nTotal = ActionsManager.total(rTurnHDRoll);"

This part fails for rTurnHDRoll after "ActionsManager.performAction(nil, rSource, rTurnHDRoll);" runs. rTurnHDRoll does not have rTurnHDRoll.result set.

Okay, so I created another onRoll_TurnCount and added the handler for this and it does set the .result values there... I was hoping I could handle the output for the results in the same place as the other but guess that is not going to be possible.

This is from within the "turnundead" onRoll:
Runtime Notice: s'manager_action_turnundead.lua' | s'onRoll' | s'rTurnHDRoll' | { s'aDice' = { #1 = s'd6', #2 = s'd6', #3 = s'd4', #4 = s'd4' }, s'nMod' = #0, s'sType' = s'turnundead_count', s'bSecret' = bFALSE, s'nTarget' = #99, s'sDesc' = s'Turn Undead' }

This is in the onRoll_TurnCount for type turnundead_count.:
Runtime Notice: s'manager_action_turnundead.lua' | s'onRoll_TurnCount' | s'rRoll' | { s'aDice' = { #1 = { s'result' = #2, s'type' = s'd6' }, #2 = { s'result' = #6, s'type' = s'd6' }, #3 = { s'result' = #2, s'type' = s'd4' }, #4 = { s'result' = #3, s'type' = s'd4' } }, s'nMod' = #0, s'sType' = s'turnundead_count', s'sDesc' = s'Turn Undead', s'nTarget' = s'99', s'bSecret' = bFALSE }
Runtime Notice: s'manager_action_turnundead.lua' | s'onRoll_TurnCount' | s'nTotal' | #13

So it seems it doesn't even get the result until after the fact so... I'll see what I can do

Thanks for the pointer and insight.

Yeah, you see you have the result for each individual dice as well as the total. This is only available after the dice have fully landed, and not in the same function as when the roll is initiated.

Is there some similar magic to get "rTarget" to be populated? The action doesn't seem to populate rTarget even if a target(s) are selected by the actor.

onRoll and modRoll both show rTarget = nil. I've been going over manager_action_attack and _damage but can't seem to see the immediate cause yet.

Targeting is usually encapsulated in the draginfo data structure - for both dragging and the targeting system.

ActionsManager.actionDirect does not use targeting.

ActionsManager.performAction does use targeting if the draginfo data structure is included.

In the 5E ruleset, have a look at how the attack or damage actions are initiated from the weapon record. Look at campaign\scripts\char_weapon.lua - the onAttackAction and onDamageAction functions, these both call the relevant action handler "performRoll" functions including draginfo.

Good point, I did note the draginfo portion, I'll poke around that. What I ended up doing in the meantime was pulling the <targets> node from the rSource. It worked but I'll see if I can work in rTarget instead.
