A macro that repeats x amount of times

Hi, I do apologise if a question like this has been asked before however, I cannot find it anywhere nor am I skilled (or really have a clue as to what I'm doing with macros). I've been adding macros to tokens to develop a monster manual for my games and everything has been working so far, but like a few others I have reached the Hydra.  I've added an attribute to the Hydra to represent heads which I've linked to the green bar for the token. Can I get the macro to repeat an amount of times equal to that attribute? Ideally acting like a multi-attack for the Hydra. This is the code inside the macro to attack with one singular head: %{selected|repeating_npcaction_$0_npc_action} Any help on the topic will be great, if it's not achievable its no big deal but I thought I should ask. Thanks!

The base macro syntax has no support to loop or repeat. Such things are limited to Mods (a Pro subscription perk). An alternative would be to use a Chat Menu setup with different buttons to call the ability a differing number of times.

This might be one of the most asked questions, and is a feature that Roll20 really should support (just after modifiers on rollableTables IMO).

I agree with RainbowEncoder, your best right now (without a Mod, a Pro feature) is to use a Chat Menu setup. 

GiGs said: This might be one of the most asked questions, and is a feature that Roll20 really should support (just after modifiers on rollableTables IMO). I know it's a script, and therefore requires a pro sub, but Muler lets you roll against a rollable table with modifiers.

Just as a matter of elaboration (all these answers are correct), the macro syntax is not a programming language in the traditional sense, It doesn't support logic, branching or looping, and very little in the way of variables. It's primarily a souped up dice roller, capable of being run on manual command, accepting some (user or random) value input, and then printing a result to chat. Very clever users have found ways to push this to the limits, but there are limits.
