im unsure if this is should be a question or a suggestion so ill say both, Monument Puzzles, wondering if there is a way we could add a green, blue or red card door + the  reader to open the door using the mod, im unsure if its possible or if its already available, but it would honestly be amazing if i could block 1 of the hangars at airfield and turn it into a red room

correction i mean plugin.... not mod smh

The puzzles feature is still being worked on. I've been busy lately so it'll be a while until it's released. You can try it out by downloading the plugin from the develop branch on GitHub.

Basically just spawn the entities in that you want, then equip a wire tool, run the mawire command, and connect the entities together. It won't feel completely like vanilla wiring due to client-side limitations, but it's close enough.

thank you very much! i can't wait for it to be released! keep up the great work bud!

Awesome!
