@Toothless: Yes (usually). First you will install the scripts from the game settings page. Click settings drop drown -> API scripts. There are many available via "1-click". Click the Roll20 API Script Library dropdown and browse or start typing the name of the script you want, then select and click install. If not on the 1-click, you will have to find the source code for the script (usually linked in the main forum post for the script), copy the code, click on "New Script", paste, and "Save Script". Once installed, the scripts will be waiting for input. Depending on the script, this will either be through passive "listening" for VTT events (like moving a token, turn order change, creating a token, etc.), or they will have to be called from the chat either directly in the chat window or from within a macro or character ability. E.g. "!token-mod --help". The specifics of the commands will be described in the main forum post for the script and/or from api script page if installed from the 1-click menu. I recommend going to the main forum page for each particular script regardless as it often has more comprehensive guidance for use. Just Google Roll20 <scriptname> and it usually gets you to the right place quickly. @Gold: I haven't seen DotMM, but the answer is... probably. There may need to be some setup. From the DoorKnocker description (emphasis mine) Using Door Knocker The script will move dynamic lighting lines used as doors to the map layer and make them transparent, opening the door. It determines what is a door and a wall based on the stroke color of the polygon and will only open doors within 1 square (default 70px) of the door knocker token. Hopefully, the doors are a different color than the rest of the DL lines (they probably are). If so, you will need to configure DoorKnocker for that color "door". It's described in the DoorKnocker page here , under "Setting up DoorKnocker".
