AD can do this just fine, but then you don't have an Eddie. 

with func illusionaries/trigger_once and health set on them/killtargeting alpha func_walls and some clever scripting which is prone to breaking for speedrunners and the like.
But i'm sure it can be done even in quoth. 

What's with everybody and their aunts adding Edies in their maps? The dude belongs in Q2, he doesn't fit at all in Q1 IMHO, not even in base maps. Quoth's lovecraftian monsters do, but they seriously need to be better animated. 

I like to use him as a mini-boss or key guardian. He fits well if you imagine the enforcer's and grunts engineering a secret weapon or so. Anything can fit if you build the story.

What I like about Eddie is that he can fit not only in Base but also otherworldly maps. 

Centroid
Armagon 

is a weird enemy, can't say I am too fond of him. 

It's true he's a tough opponent, I just wish he got a more suitable design that doesn't make me think I'm suddenly fighting Stroggs. BTW, it's Edie with one D, like the character in Iron Maiden cover artworks - his red optical device comes straight from Stranger in a Strange Land.

@Preach Yeah, I don't feel like these two look very quakey either. I'm more for full-on lovecraftian. If I get good enough at mapping, I'm thinking about making a full mod that would go this way rather than cyber. 

I'll admit that Ol' Ed is more "strogg" than many Quake monsters, but to me that seems preferable to including Shamblers or other enemies of that kind when making a base or otherwise "futuristic" map.

Besides, gore/horror is not exactly new to that theme. The Grunt is not obviously mutilated, but his texture has a decent amount of blood spatter and his lore claims that he's a mind-controlled drone of sorts.

Anyway, about that func_illusionary... 

The thing is that Quake's a very broad church, and if you have very specific ideas about what you like, you shouldn't be surprised if people fail to conform to it. 

Well, i guess my other post beforehand vanished into the ether.

I'll simplify it anyway. Is there any way to remove a func_illusionary? I tried giving it a targetname and killtargeting or targetting it, to no avail... 

func_illusionary is converted to a static entity when the map loads, so it can't be killtargeted. 

Yet another roadblock :( are there any other brushes that monsters can see through? 

"that seems preferable to including Shamblers or other enemies of that kind when making a base or otherwise "futuristic" map." I beg to differ. Since base maps are overrun by Shub's forces who teleported in, all of the Quake bestiary can fit in. Granted, Shamblers are supposed to be some kind of high ranking officers in Shub's army and generals usually send cannon fodder on the frontline instead of going themselves, but base theme was designed to be used only as the starting point of an episode. We should move this discussion elsewhere, we're cluttering the thread with off-topic. 

You can use a func_illusionary and then change its classname to mapobject_custom. This allows it to be killtargeted.

Sage words from Preach the almighty.

I used this very trick on the jam 7 entry! 

Thanks for the tip! I'm away from my development PC at the moment, but i'll test and report back when I can.

Mugwump, I'll post in General Abuse I suppose. 

I've found plenty of useful info thanks to your links but this one eludes me: how do I set a brush to nodraw in TB 1.16? 

Well, it's almost there. The monster sees the player through the mapobject_custom, but they don't seem interested in shooting them. They just try and path to them, which involves essentially rubbing their face up against the glass pitifully.

How did monsters handle your trick Bloughsburgh? I'd be interested to hear if they were more functional than mine. 

It seems to be caused by the trigger_once, if I move/remove it the monster will behave properly. :( 

I have committed the mortal sin... Maphacks in a mod. But hey, i'll take anything at this point.

My solution to my own issue was to use this wonderful guide (which I am sure everyone is already familiar with) to build a trigger which activates whenever it's touched by anything, such as a nail from the monster or any other projectile, as well as when it's physically touched by the player.

This allowed me to work without the health value, which was what was making the trigger stop monsters from shooting.

Sadly, the trigger isn't activated by hitscan weapons such as the shotgun or lightning gun. I don't suppose anyone has any advice on fixing this, or will i have to settle for this in my map? I could bear it, it's already mostly working after all... 

Mug, are you referring to the SKIP texture perhaps?
Any face with the SKIP texture will not be drawn. 

No. I built a flight of stairs of 16 units tall each, but climbing/descending them results in a choppy movement, so I wanted to build a slope over it and make it invisible to smooth it. I've read that you can do that by setting a brush to nodraw. Besides, I don't seem to have a skip texture in my wad (I'm using Q.wad). 

Invisible solid brush?

8 unit stairs are smoother for ascending but I figured you intentionally want them beefy steps. 

Well, they were my first stairs and I wasn't sure about the proportions. I built one step and thought it looked good, so I went on with the whole staircase. Only after finishing did I realize the movement was choppy. I don't want to discard the whole thing because I spent quite some time on it and I really like how it looks with the texture I used, so I need an invisible slope over it. I'll build them steps 8 units tall next time. 

Yes, use a Clip brush that is paint the CLIP texture on your stair slope and it will be invisible yet solid.

Clip brushes are also handy to prevent the player from getting stuck on strange angles like pointy corners and such. Also, big stairs are fine I was just presenting an alternate form of them. :)
