If you can, write please mini-guide how to do it (would be good if you also add some pictures)

Or just let the link to guide if it is already there (i don't found)

if you didn't add the Garrysmod.fgd to the mapping properties, then do it like this:

1. create a point_serverside/point_clientside entity (depends wether your code is executed clientside/serverside)

2. add the this code to the execute console command: "lua_run/lua_run_cl <executed code>"

3. add an input to the trigger, wich triggers the point_serverside/clientside.

4. compile map

5. test map.
