Target token, roll to attack, and apply damage if hits

I really like roll20 but I am playing in a game on Foundry. One of the things I really like on Foundry is that I can hold ALT and target a creature. When I attack that creature it automatically calculates whether or not it hits and it removes the HP for the damage roll. Is there something like that on roll20, maybe an API that can be enabled?

There are ways to do that for Pro users, using API script solutions. How to do it depends on your system, and what attribute names are.

I do have a pro subscription and access to the API scripts. Can you tell me what scripts I should use? I could not find anything there that does what I want so far.

To change attributes from a macro you'll need to use an API script (pro subscription) like tokenmod ,  chatsetattr ,  groupCheck ,  applyDamage , or similar.

Then once you get the hang of the scripts that Vince shared, you can start to string together some conditional logic with the Scriptcards api script and have that script farm out scripts like token-mod or chatsetattr.

Nick Olivio has a great and simple video on YouTube to do this with powercards. 

Thanks for all the info everyone. I will take a look at this stuff.

I've been trying to find an universal api/macro that does this. Unfortunaly the Nick video method you have to build each attack individually.&nbsp;
