can we do IF statements?

i'm wanting to some how set up a macro called "consentration check" where it will automatically roll 1d20 + con (or 2d20k1 + con if warcaster) then see if it is above 10, then IF it is below 10 run a macro to remove the consentration status marker... i know it seems weird and i may not have described it properly but i hope someone understands and can answer

This would have to be a custom API script. Normal macros cant do if statements, nor can they change anything about a character sheet or token. I believe there are a couple of status marker scripts already floating around - maybe one of them can handle this.

i use tokenmod, but wouldn't know the coding for that API and i wouldn't even know the first steps to making an API myself.

If token mod sets the status marker with a o (to remove) and 1 (to set), you can add something like this to the token_mod command: [[{1d20+@{selected|con}}>10]] This will give a 1 on success, and 0 on fail, so can be used to set or remove the marker.

If this is 5e, the math you want for your macro is: [[ {?{Advantage?|Normal,1d20|Advantage,2d20k1|Disadvantage,2d20kl1}+@{selected|constitution_save_bonus}}>[[{floor(?{How much damage did you take, if over 21?|0}/2),10}k1]] ]] To include DC over 10 depending on damage, and Advantage. Leaving the damage at the default of 0 will result in a DC10 (as will entering any damage amount less than 22).

This is a very simple script that may help. It does one thing. It looks for a change on bar 1 of the selected token. If that change is a reduction, and the token has the indicated concentration marker, then it posts a message that a concentration check is required. It also gives a chat button for the check. That version also includes a button to toggle the concentration token marker, but for the button to function, requires token-mod to be installed as well. It does not inform you that a given token is concentrating, set the concentration marker to begin with or monitor spells cast and automatically apply concentration. It is a very short and simple script.
