How would one spawn an entity such as a tf_projectile at a specific location in the map, as opposed to using ent_create which spawns it at the location of the player's crosshair?
Then make tf_projectile_spellspawnzombie entity in hammer, give it a targetname keyvalue, name it and use it as reference
That would be because it's not defined in the FGD. It still exists, Hammer just doesn't know what it is in its own little dictionary.That's the problem. It doesn't exist as an entity in hammer.
