How to spawn custom monster using "thing spawn"

[TheGuy]

(I'm using ultimate doom builder in Doom 2 UDMF)

Ok so I know how to spawn an actor that's already in the game using the "spawn thing" command, but how do I spawn a custom actor that I added to the wad? It doesn't appear in the option when I have to select the "Thing Type".To clarify, I'm trying to make it so that said custom enemy spawns in a Map Spot once I wald over a line.

 

Here's the custom monster I'm trying to spawn

You can give the monster a SpawnID (best something over 200) and use this number as the argument for Thing Spawn.

 

Alternatively, you can leave the argument as None, and add a custom field arg1str in the line's custom tab, set its type to string and its value to Troopod (or how the monster class will be named).

Your other option is to use SpawnSpot or SpawnSpotFacing, both of which use a string as the argument for identifying the thing to spawn:

 

SpawnSpotFacing("Troopod",<mapspot TID>)

Thank you, that worked. Do you know where I could find informations like that in the future? The ZDoom wiki is weird to navigate when it comes to highly specific stuff like this.
