Hot on the heels, the promised hack that lets us ignore the order the entities are placed in the map, but still dictate the order that triggers fire.

https://tomeofpreach.wordpress.com/2018/03/06/the-alternator/

The article also includes how to make an "alternator" - a setup where a single input trigger switches between activating two different targets. 

Imagine you have several shootable triggers or buttons and want to fire an event once a certain total amount of health has been depleted. The damage done to the triggers transfered to an independent source, so to speak. So you can shoot each a random number of trigger a random number of times and once the overall health depletion reaches n, the event fires. Basically like a counter based on "health" instead of "count". 

func_button.target > W_FireAxe notnull hack
W_FireAxe hits a func_door.
Func_door.health = 1000 or 2000 etc.

And voila, just add func_buttons. 

but, don't you want the player's actual weapon damage to matter? E.g. shooting it with 10 nails should cause less total damage than 10 rockets. 

Make as many "shootable buttons" that you need. Select all of them, turn them all into one func_door with a health value, give it a target, set lip equal to bounding box so it doesn't move. 

The sum of all damage done combined. No idea if it's possible, and the applications would certainly be limited. For the lack of a better example: a machine needs to be damaged by a certain amount in order to be charged or explode and there are several exposed shootable parts. You can focus on a single one, or shoot each of them equally - the event fires once its global health is depleted. 

Exactly was @ metlslime.

But yeah, turning them all into a single door or button should work. Though what happens if they are supposed to be spread all over the map 

yeah, will you exceed max efrags and it disappears? I think in modern engines the efrag issue is solved and it is always drawn maybe... 

Nothing as far as I know, so long as the lip is set right for whichever movedir is set. I can't recall if func_button has an option to be silent in vanilla, so a func_door probably would work better. 

And yet, I have another possibly simple or already-answered-but-I'm-too-dumb-to-find question: how to spawn fully functional movers like trains, doors and plats half-way through the map? Basically invisible until triggered and then working like normal entities. Think "use" "func_wall" but without being thwarted by precache functions. 

I'm indeed stupid. It should work just fine that way as long as you override the sounds. Or is there anything more to it? If not, please delete me. 

inline models are implicitly precached, so those are not an issue for doors/plats/trains/etc.
while they'll have a model string set, their starting modelindex will be 0, which means they'll remain invisible until they're properly spawned.

regarding sounds, you can just have a second door/plat anywhere else in the map, its sole purpose being to precache the required sounds.

a bigger issue is that if you're using use+targetname, you'll have no way to clear said targetname before the use is called.
this means that plats will need to be triggered twice (one to spawn, once to activate them so that they can be used).
doors are more problematic - you'll need to manually create a trigger field around the missing door to allow it to open, and you'll need to spawn that trigger field the same way as the door otherwise they'll spawn the door when you walk through them the first time. 

Reaching back to this post from 2009 and trying to understand something.

Would this allow for a silent trigger_push? My set up is:

classname info_notnull
use InitTrigger
touch trigger_push_touch
speed 500
angle 90
spawnflags 2
targetname test

Mark V and Quakespasm are still complaining about not caching the ambience/windfly.wav sound file. I thought this was the whole point of this hack.

Thanks! 

Just put a trigger_push out in the void and it will ensure that sound is precached and avoid the warnings. 

Yep, that's in the map off in a tiny room but the hack'd entity plays the sound in that case.

The intent is to make a delayed spawn trigger_push. The sound precache is the reason we have to do something a bit different to the standard "classname as use function" hack, it's what we're trying to work around. But the lack of sound is not intended - I would pair this with a regular trigger_push hidden somewhere in the map to perform the precache and remove the warnings.

You'd have to be pretty creative to get rid of the flying sound, only thing I can think might work is finding an entity hack that sets fly_sound on the player to an impossibly high value using ltime shenanigans on a doctored movetype_push entity. Haven't quite cracked that yet.

On a related note, this has reminded me of an undocumented Quoth 2.2 feature: you can specify the sound a trigger_push makes using the "noise" key. You can create a boiing! noise for jumppads, or using "misc/null.wav" will prevent any sound being made. Will write that one up when I get back... 

Alright. I was afraid of that, but luckily it's for academic purposes not a real project. Great news about the noise keys in Quoth 2.2 That does open up some possibilities. Thanks for the response.

I hope you get a chance to play my 100b4 entry. Lot's of sound work went into it. 

The pack is next on my list, so I'll watch out for it! 

Hey everyone :) So earlier someone on the TB discord asked if it was possible to make a brush that acts like a HL style func_breakable so I did some fooling around and figured out how to do it! Now this is pretty easy stuff that probably isn't really worthy of going here but I'll post about it anyway lol. So here is how you do it, you make a func_wall as you would normally do, then after you've made it you add a few keyvalues to it. First add a takedamage key and set it to 2, that allows it to take damage, obviously. Then you add a health field and set it to however much health you want the breakable to have. Then when it's health reaches 0 it will try to call the function in the th_die field, if there isn't one the map will crash as I found out :D So add th_die and set it to SUB_Remove or any other function that calls SUB_Remove at some point, depending on what your needs are. Optionally you can add an armortype and armorvalue to give the breakable damage resistance so it can be broken with some weapons but not others. I haven't exactly figured out how to customize the sound it makes when you hit it or break it yet but I will keep trying and see if you can do it without needing a mod 

So after a little more discussion I've figured out how to add sound playback to the breakable, so the full setup looks like this:

Func_wall
takedamage = 2
health (whatever you want it to be)
armortype/armorvalue (whatever you want it to be
noise (whatever sound you want the brush to make when you hit it but don't break it)
th_pain = train_wait (plays sound in noise field whenever you hit it)
th_die = SUB_UseTargets (targets 2 separate info_notnull's that play the sound you want to play when the object is broken and removes it, respectively)
target = the name of the 2 notnulls

Notnull 1
targetname = whatever you put in the target field of the breakable
noise = the sound you want to play when the breakable breaks
use = train_wait (play the sound when triggered by the breakable dying)

Notnull 2
targetname = same as the first one
killtarget = name of the breakable
use = SUB_UseTargets (remove the breakable when this gets triggered by it dying)

Please feel free to correct me if something I put is incorrect, I'm still pretty new to q1 mapping and map hacks especially. But map hacks are really fun and I've almost become more interested in them than actual mapping at this point (but not completely though) :P I'm also trying to think of how to add rotation to a turret hack I made last week but I haven't really checked any of the quake c sources related to rotating functions to see which ones I might be able to use 

That's a really well constructed and described hack. Welcome to the thread!

In terms of rotation, a warning and two pointers. First warning is that standard Quake just doesn't do collision on rotation. The amount of highly specialised code that mods apply to get even crude approximation of rotating solids, I wouldn't expect a hack to be able to get anything like collision working.

If you just want visible rotation things are better. There are already suggestions in this thread about how to use avelocity for simple looping animations. If you're looking for something more triggered, you might want to look at SUB_CalcAngleMove. Although any entity which used the function got cut from the final release of Quake, it's still available for hacks to use.

Alternatively, you might want to look into the AI functions if you'd like rotations that follow the player. You need to set quite a few keys on an entity to trick the game into running some of the built-in AI stuff for turning to face an enemy, but it should be possible. More advanced stuff, but something to get your teeth into... 

Having your breakable also create some info_notnulls using external .bsp models for rubble and have a movetype 6 would be cool too. Can't remember a good way to give them starting velocity at the moment though and still be triggered on break. 

Thanks :) I got the idea for the armor from one of your articles https://tomeofpreach.wordpress.com/2013/05/11/trigger_damagethreshold-simulator/#more-974 I may add it to the turrets too if possible. Speaking of, I will definitely look into the AI turning/rotating functions to see what I can do with them 

How can I make worldspawn shootable and killable?
Perfect accuracy gameplay challenge...
