ChatSetAttr Help

1643842803
I was wondering how to subtract one until it reaches 0 This is a custom sheet BTW Here is my code !modattr --silent --name @{character_name} --exhaustion_status|[[@{exhaustion_status}-1]]!!!  It works fine but always goes below 0 and i would like it to stop at 0. I tried using the !modbattr but for some reason it always uses the max value instead of 0 to max like description says.

Well I spoke to soon it works but part of the code shows up in the chat window.&nbsp; The code works and does what i want but not the correct way. I had to return the button code to get it to work, im still a noob when comes to coding.&nbsp; I know your suppose to leave button code all on same line.&nbsp; Im up for any suggestions!!!! Please. When i put them in the same line like we are suppose to the second !modbattr is ignored.&nbsp; I tried --modb for the second one but it still doesnt function as intended.&nbsp; I know there is a Long Rest API already but its not for my custom "Modded" sheet (5e Community Contributed), since i dont know how to code the API, i was working on something i understand a little more. I tried removing the first end of Code String (!!!) to see if that was my problem but the same results. &lt;button type="roll" class="sheet-roll" name="roll_Long_Rest" value="&amp;{template:5eDefault} {{character_name=@{character_name}}} {{title=Long Rest}} {{subheader=@{character_name}}} {{simple=1}} {{freetextname=@{character_name}}} {{freetext=Has taken a long rest. Max HP restored, Spell Slots reset to 0, Temp HP reset to 0, Place Holder..}} !setattr --name @{character_name} --spell_slots_l1|0 --spell_slots_l2|0 --spell_slots_l3|0 --spell_slots_l4|0 --spell_slots_l5|0 --spell_slots_l6|0 --spell_slots_l7|0 --spell_slots_l8|0 --spell_slots_l9|0 --hp|@{hp|max} --temp_HP|0!!! !modbattr --name @{character_name} --exhaustion_status|-1!!!"&gt; Take Long Rest&lt;/button&gt;

Fwiw I find that modb and other bindings to 0-max typically are counterintuitive.&nbsp; I actually want to see that they have gone negative so I know the players out of them.&nbsp; The API response when its modding nothing does not reveal that.&nbsp; So a player can be at 0 level 1 spell slots left but the chatsetattr command will say its reducing slots by 1 to 0 even though it went 0 to 0.&nbsp; Its actually ok to go negative and inform you that they are out that way.&nbsp; When api's like resting in style&nbsp; fire they will reset the negative to the max.&nbsp;&nbsp;

I tried --modb for the second one but it still doesnt function as intended. What does it do then? Does it not work at all, or changes the value in some other way? Maybe --mod is what you intended, not --modb ? The readme on github have some stuff that isn't mentioned on the wiki page: <a href="https://github.com/Roll20/roll20-api-scripts/tree/master/ChatSetAttr#readme" rel="nofollow">https://github.com/Roll20/roll20-api-scripts/tree/master/ChatSetAttr#readme</a> <a href="https://wiki.roll20.net/Script:ChatSetAttr" rel="nofollow">https://wiki.roll20.net/Script:ChatSetAttr</a>

From the documentation: --modb &nbsp;works like&nbsp; --mod , except that the attribute's current value is kept between 0 and its maximum. You can use&nbsp; !modbattr &nbsp;as a shortcut for&nbsp; !setattr --modb .

&lt;button type="roll" class="sheet-roll" name="roll_Long_Rest" value="&amp;{template:5eDefault} {{character_name=@{character_name}}} {{title=Long Rest}} {{subheader=@{character_name}}} {{simple=1}} {{freetextname=@{character_name}}} {{freetext=Has taken a long rest. Max HP restored, Spell Slots reset to 0, Temp HP reset to 0, Others Here}} !setattr --name @{character_name} --spell_slots_l1|0 --spell_slots_l2|0 --spell_slots_l3|0 --spell_slots_l4|0 --spell_slots_l5|0 --spell_slots_l6|0 --spell_slots_l7|0 --spell_slots_l8|0 --spell_slots_l9|0 --hp|@{hp|max} --temp_HP|0 --modb --exhaustion_status|-1!!!"&gt; Take Long Rest&lt;/button&gt; So setting the code like above all in a single line and using --modb&nbsp; everything infront of it doesnt do anything except --hp|@{hp|max}&nbsp; everything after the --modb works like a charm like its suppose to. Its like it ignores the first Setattr and only using the --modb which the --hp|@{hp|max} can work on it as well. But if i break the button code into 2 separate lines with in the code both work, but i get this Update - I think im just going to change it to all work from a Macro.&nbsp; Seems to work fine.

Isn't there a long standing issue with selected/target calls and multiple api commands?&nbsp; Sometimes randomly it will ignore the second command?

There is a bug where Roll20 drops commands , but the one I'm aware of does not require selected/targeted interaction. As well, I'm not sure it would apply to Rouse's last example, as that one had everything in a single command. Can yo tell us... Are the spell slots repeating attributes or standard attributes? Because the ones that look like they work seem like they are standard attributes, for sure.

Is there a way to use this in a macro in a way that, the macro inputs a spell level and that spell slot is depleted by 1

So this is how i coded it into the 5e Community Sheet , you will need to alter --name @{character_name} --spell_slots_1 to match your sheet attributes you are using. You will also want to change the 1!!! to -1!!! !modattr --silent --name @{character_name} --spell_slots_l?{Cast at what level?|Level 2,2|Level 3,3|Level 4,4|Level 5,5|Level 6,6|Level 7,7|Level 8,8|Level 9,9}|1!!!
