 Re: Return objects to their spot?
Posted by DrGlass on Wed Dec 15th at 1:34am 2004

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...

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

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...?

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