Despite what it may seem, adding custom entities and other things is easy once you get the hang of it. Follow these steps and you can have the hhh or a rtd variant designed to fit your map! 1.) spawn an entity in hammer, wherever you want. 2.) give it a title that fits what it is, for the sake of this tutorial, let's say headless_hatman 3.) you will see nothing in the keyvalues section, let's fix that, shall we? Hit 'add' on the right side. 4.) give the key the title "targetname" and the value "headless_hatman" 5.) hit ok, and your done! Compile the map and you will have the entity right where you placed it. 6.) if you made the HHH, RUN!!! YOUR IT!!! Thanks for reading this, hope it will serve the community well. Feel free to leave notes if there are any other things you think are important. NOTE: don't listen to the obsolete model, if you follow the instructions, the entity will work fine.
