those simple questions thread...

That's the video I was talking about. Thanks for sending it again.

Is there a way to use env_toggletexture with textures that utilize an envmapmask? I'm looking to have a portion of a texture glow after it is triggered. The env_toggletexture came to mind but the alpha channel is used for the multiple frames. Any ideas?

[Dr Evil]

Is it possible to have a teleport with random destinations?

[joe_rogers_11155]

@dr evil: just use logic_case to pick something at random. up to 16 choices. you will have to build 16 teleport locations so it wont be totally random across any location in your map...but you can choose randomly from 16 specific locations.

I'm not sure on specifics, but maybe you could use some math and such to create a random set of co-ordinates to teleport to? And maybe some if's and such to prevent values being too high or low. Just a thought.

[joe_rogers_11155]

if you don't think having sixteen places to choose from is enough to simulate randomness, then you can simply add in more logic_cases to increase the amount of places.

Thanks for the info, I've never looked into using a logic_case ent but i'll give it a shot

Anyone know some tutorials that could teach me how to use Source Particle Editor?

[joe_rogers_11155]

i would recommend talking to janga or some of the other frequenters of the particle pimpage thread. i've looked for some good tuts myself and haven't found anything i can wrap my head around.

Ok, I am trying to modify an npc to be able to have a weapon and for it to have the choice of which weapon it has in Hammer. However, i have no coding knowledge and haven't been able to find what I need on the internet. So if anyone knows what the code for an npc to be able to do this, please give it to me.

If you need the code I am modifying for that, here it is:

If you change the parameter ShouldLookForBetterWeapon to true, at least he would pick up a better weapon right ? So if you place it in front of him..

I have question about ambient_generic and it's client side properties. For example: I have two rooms on my map. In one room there is ambient_generic inside, which plays music. Map is multiplayer for CS:S. I would like to make something like this: Player inside room with ambient_generic hear music, but second player which is on the other room - don't hear. And the main problem and question is: Ambient_Generic is client-side, or works globally to all players on the map? Ambient_Generic is with switched on flag " Play Everywhere ". I made it using trigger_multiple with outputs: " on start touch , volume: 10 " , " on end touch , volume 1 ". But i dont know how it will work in multiplayer. If Ambient_Generic works globally - player by entering trigger will globally change the volume of the ambient_generic, to all players. Anybody know how it works? Sorry for my bad english

[Ark11]

Maybe you could make the ambient_generics 'MaximumAudibleDistance' parameter to the size of the room. You can go to the top bar of buttons in Hammer and go to View then click an option called 'Show Helpers'. Then a big circle will appear around your ambient_generic. It'll visually show the audible distance, and may make it easier for you to make it to the rooms size.

[adr_n]

MaximumAudibleDistance don't work properly - real audible distance in game doesn't match to big circle around my ambient_generic. For example: I have set 100 in this value, and in game i hear music like i have set something like 1000... . So only idea in my opinion is to make it like i said on upper post, but i dont know how it will work in multiplayer. I know only, that if some player turn on ambient_generic with flag " play everywhere " , everyone will hear music, if stop, everyone in same time won't hear -i saw this on some map. So it works globally. But i dont know how it will work with " volume " triggering.

I'm having some kind of strange leak in my map. I can compile the map just fine but If I hide everything but the bare necessities (skybox, real world brushes, nodraw) I'll get those "FindPortalSide: Couldn't find a good match for which brush to assign to a portal near...." kind of leaks:

Code: Select all

Leaf 0 contents:(may vary)
Leaf 1 contents: CONTENTS_SOLID (may vary, e.g. CONTENTS_WATER)
viscontents (node 0 contents ^ node 1 contents): CONTENTS_SOLID (ditto)
This means that none of the brushes in leaf 0 or 1 that touches the portal
has CONTENTS_SOLID
Check for a huge brush enclosing the coordinates above that has contents
CONTENTS_SOLID
Candidate brush IDs:

It doesn't give a candidate brush ID and if I go by the coordinates it takes me out to the void. No pointfile is generated either, the map is sealed up. But as long as at least one entity exists (not hidden) in the map, it compiles fine.

So I suspect a brush or entity somewhere is causing this to happen, but that's just a guess.
