Need help with modding hl2

Hello everyone :) can you guys tell how  i can  replace a npc with another existing npc (example:replace all citizens with metrocops) without using a map editor?

I dont want to replace their models, i want to replace them fully. I want the replaced citizens to act just like a metrocop, not just replace their models.

Its hard for me to find a solution because its not as easy as replacing enemies in doom.

Thanks in advance :)

well, you need to either use a map editor, or edit the source code to replace citizens with metrocops

are there any tools to make this possible?

source sdk

thanks :)

do you think that it would be able to make a randomizer mod on source sdk?

Source Engine Randomizer

I've only been modding Hl2 for a month but I have some advice to get you started:

• don't launch the tools from steam, go to your hl2/bin directory and launch em from there, the launcher has been broken for a while
• if you want to make characters speak custom voice lines, you will have to use Faceposer, which is pretty broken on modern Windows, use this video to help fix it
• get GCFScape
• if you want to edit original hl2 maps, you have to decompile them, as the ones that come with hl2 have been compiled and are unreadable by Hammer
• your pc isn't the issue, the Source SDK is just unstable on newer operating systems(and older ones)

you don't need to decompile the original hl2 maps, the original sources have been released here: https://hl2-beta.ru/index.php?action=downloads;sa=view;down=62
