The Ladder Spawn Behavior

[ItsInmansFault]

Hello! I recently rediscovered my love for the Ladder, and I was curious about the enemy spawn behavior. I can find the  models and stuff in the pk3, but wanted to know which file the logic is that says who spawns when. If I only end up being able to alter the npc's for Ladder, cool, but the idea was to understand it to possibly replicate on other maps. I also had the thought that if this was not terribly hard, someone else would have done it a long time ago. I have never created my own mod for a game, but I have a very strong technical background and understand scripting, etc. It seems this forum is still relatively active, so any help or advice would be greatly appreciated. 

Side note: It's been amazing to watch my 10yr old cut his teeth on the Ladder. LOL!!!

There are different ways to do it, but typically a wave of NPCs will use their npc_target property to use a target_counter on death, which counts up to the total number of enemies in the wave and then triggers the next wave. If that's the way it's built, you'll have to edit the entities in the bsp file, for example using

It's all in the map file (.bsp file, though the .map file included which is the editable version)

Here's the tutorial on doing a ladder style map:

Awesome! Both great replies. I will look into both. It's funny because I was just telling a coworker today that I suspect it might be in the map file.

Oh, if the .map is included, it's probably simpler to edit that using NetRadiant Custom and recompile it instead of trying to edit the entities in the .bsp.
