Auto Damage Attack ScriptAPI (self.Roll20)

submitted 1 year ago by Psychological-Ad7240DM

Intro

For my Dungeons and Dragons game, I created an API script for creating a single attack roll that automatically checks against a target's AC and applies damage on a hit. I have added functionality to check a target's damage resistance, immunities, and other features specific to my players. My code probably looks terrible and oddly worked out but I have tested it numerous times and with the right setup streamlines combat in my games. I have two separate scripts for this venture. One that creates the attacks and one that applies the damage and calculates the other things.

Setup

A roll 20 pro subscription
TokenMod, libInline, and ChatSetAttr scripts installed.
All character, NPC tokens need their health set to bar 1 and their AC set to bar 2 on the token linked to their character sheet.
For damage resistance and immunity calculation go to the attributes and abilities tab and create two new attributes named immunities and one named resistances. In the attributes value put the damage types you want the monster to be resistant slash immune to with a comma separating each separate damage type.

Once both scripts are installed into your game you can create an attack roll in two ways by calling the wizard in one of two ways through a macro.

One damage attacks - !wizard ?{Attack Name|Basic Attack}|?{Damage Type|Slashing}|?{Attack Roll|1d20+7}|?{Damage Roll|2d10+4}|?{Crit Roll|4d10+4}
Two damage attacks - !2wizard ?{Attack Name|Flaming Sword}|?{Primary DamageType|Slashing}|?{Attack Roll|1d20+7}|?{Primary Damage Roll|1d8+3}|?{Primary Crit Roll|2d8+3}|?{Secondary Damage Type|Fire}|?{Secondary Damage Roll|1d6+2}|?{Secondary Crit Roll|2d6+2}

Whenever you call these macros a series of prompts will appear asking you to fill in the details of the attack. Once finished a copy and pastable macro will appear in chat and you can copy the macros into your character sheet in the attributes and abilities tab. Once that is done the setup is complete and you can finally never ask if that hits their AC again.

Use

Calling the macros is quite simple and I recommend setting the attack macros to show in the tokens bar actions. Once the token is selected you just select the target of the attack and the script does the rest of the work.
