Return objects to their spot?

I know about the prop respawn, but lets say I have a map with a deep
hole, and I dont want all my props sitting at the bottom of the hole
the whole map, but I also dont want them to dissapear if they are NOT
at the bottom of the hole.

So, do you think there is a way to teleport objects back to their
original position if and only if they fall into this hole? I was
thinking about a teleport system (in the fist part of HL2 there was a
mini teleport that would move props) but that would only be able to zap
them to one point...

any other ideas?

If only there was some way to fire the OnUser1 of whatever fell into the hole this could be so easy...

<DIV>couldnt u set a trigger in the hole wich triggered the objects that fell in the hole to respawn again outside the whole ? maybe with a little delay time ....</DIV>

<DIV>im not sure i understand what u want exactly :smile: </DIV>

ok, I want my prop_physics, for example a barrle to return or respawn
to its original position only when it falls into an area of my map that
is unreachable by the player.

the example is, a player shoots the barrel over the edge of a cliff
into water. There is no way for that barrle to be retraived by a
player becuase if they go off the cliff they will die.

the use of respawnable props would make this possible, only problem I dont want them to respawn unless they fall off the cliff.

You could give the barrels like 10,000 life, and have a trigger hurt that only affected physics objects and do...1000 damage/sec? 10000 dmg/sec?

How about something like this:

Put a trigger_multiple at the bottom of the cliff. Set it's "physics
objects" flag. On the output tab, set it to output: OnTrigger, target:
!activator, input: Break . ("!activator" is a special name which
sends an input to whatever activated the trigger).

Now when a prop_physics_respawnable falls into the trigger, it will be
destroyed and respawn. This method means that you don't have to have
the prop damagable by any other means.

If you want to get more fancy, you could use a filter_ ent to make sure
the trigger_multiple only fires when a certain type or named object
hits it.

If you're not using a prop_physics_respawnable as your object (say your
using a func_physbox instead), you could use a similar setup with the
addition of a point_template and env_entity_maker as a way of respawing
any entity. (Set the entity's "OnBreak" output to ForceSpawn the
env_entity_maker so it can be respawned after being destroyed by the
trigger.)

That's extremely handy...how did you figure out !activator?

and is there any other little tricks like that you know?

I've been browsing through the entities used in Valve's maps (try
opening a bsp in a text editor and searching for "worldspawn"), and
they use it quite a lot.

Very nice, I'll have to do that sometime. In the meantime if you find anything particularly useful you're more than welcome to post it :biggrin:

wow! I'll try that. The map is comming along now so I'll give that a try and report back.

The only other special targetname I've found is "!player", which presumably targets the player (for single player only?)

It's used a lot in AI related stuff, e.g. ai_relationship and
npc_antlion_template_maker, to make something friendly to the player or
to follow him.

Hmm, I thought this was just player? At least when I was testing it in HL2 DM. Maybe it's either? For that matter, maybe just activator works too.

I tried this method, but the thing is that my prop_physics_respawnables
don't respawn! Any idea why, and how to fix this problem?

Take a look at dm_lockdown, this is the method I used. You're
pretty much naming a group of objects the same thing, making a
point_template to reflect it, and then use a math_counter to spawn a
new set when all of them are gone.

As I said, take a look at how Valve does it.

But that's not what I want. I want each individual object to respawn
once it is "broken" by the trigger on its own, not as a group.

I'm not sure, then... maybe you could make a seperate template for each, and forcespawn on break.

Well I kinda solved the problem with teleporters, though the items
don't return to their original spot which might be sorta weird...but
whatever. Unless there is some way to get each item to be teleported
back to their original spot...?

yes please, anymore ideas? tried them, didnt seem to work.

Is there a way to make it so when a jeep falls it will respawn?

Create an output where upon break, a template fires after a delay. Thus you get the same object spawning after a set period of time, after it has been broken.
