Cakescript lua help!

Hi there guys. I’m new to lua scripting, and i can do basic edits (like, REALLY basic edits) to Cakescript. Problem is, theres a few things I want to add to it, but don’t know how. D:
If anyone could answer my questions, I would be greatly appreciated.

  1. What code would I put in to make it so that when the CP’s press USE (lets take the map: rp_c18_v1) on the doors, they open. Also, in what lua file?
  2. Anyone know a good door ram addon? (u can answer this if you want).

Thank you so much if you can answer this.
