macro to Asking Mass Perception test

I really want create a macro to make a perception check for my players... i dont know how to start it, im really noob on roll20. I'm playiong gurps with sheet made by Authors: Devindra Payment (@Ardnived), Joseph Mason (@sdJasper), Ken Foubert (@MadCoder), Mike Wilson (@Mike W), SᵃᵛᵃGᵉ, Tame Flame

You will probably need to be specific about what character sheet you are using.  There are a lot of game systems (and editions of those systems) that have perception checks.

What game are you playing? (E.g. D&D 5th Edition?) What character sheet are you using? (E.g. D&D 5E by Roll20?) I answered almost the exact same question 3 hours ago. Here's a pretty basic one I just threw together for the D&D 5E by Roll20 sheet (you'll have to switch out all the PLAYERNAMEs for your PC's names):  /w gm &{template:npcaction} {{rname=Party Perception}} {{description= **Passive Perception** PLAYERNAME1 = @{ PLAYERNAME1 | passive_wisdom } PLAYERNAME2 = @{ PLAYERNAME2 | passive_wisdom } PLAYERNAME3 = @{ PLAYERNAME3 | passive_wisdom } }} That is for passive perception, which is a static number.  If you want a list of rolled numbers for Perception Checks: /w gm &{template:npcaction} {{rname=Party Perception}} {{description= **Perception Check** PLAYERNAME1 = [[1d20 + @{ PLAYERNAME1 | perception_bonus }]] PLAYERNAME2 = [[1d20 + @{ PLAYERNAME2 | perception_bonus}]] PLAYERNAME3 = [[1d20 + @{ PLAYERNAME3 | perception_bonus }]] }}

sorry to not say that before. I play GURPS in roll20. Ill edited my original post with more informations.

Ya, I've been trying to figure out this as well, but for runequest. So I'm pretty interested in the answer for this. All the examples out there unfortunately are specifically for D&D and the 5e character sheet.

You can use the basics of how macros are made to do your own for that system.&nbsp; The first step would be to find out what attributes are being called when you make that roll with that sheet.&nbsp; I don't know anything about that game system, but there are a couple very common things you can do to find out the structure of certain rolls. 1.&nbsp; Enable the quick macro bar in the game settings&nbsp; and drag the roll button for perception from the sheet to the bar.&nbsp; Sheets written before that bar existed may not have the roll button coded correctly to use that feature.&nbsp; Click the button on the quick macro bar and see if it puts the normal roll in chat.&nbsp; If it does, then put your cursor in chat and hit the arrow key to see the previous command sent in chat.&nbsp; This will show the command you can use to call a roll from that specific roll button on the sheet.&nbsp; It will be something like %{Bob|perception_roll}.&nbsp; Once you know that, you can change the character name to selected to be able to use it on any selected token to roll that button from their sheet: %{selected|perception_roll}.&nbsp; You can add /w gm in front of that to have it whispered to you. 2. To find the exact code the sheet uses, you can just hit the button on the sheet, put your cursor in chat, and hit the up arrow to see the last command given.&nbsp; This will be the full macro the button uses when you press it.&nbsp; If the Runequest sheet includes a roll template, this should show you how the roll template is being called, and the exact attributes used. Then you either use the template from the Runequest sheet, or the default roll template to put together a group check roll.&nbsp; The default roll template is part of Roll20 and available in every game. <a href="https://wiki.roll20.net/Roll_Template" rel="nofollow">https://wiki.roll20.net/Roll_Template</a>
