forcefield

can somebody tell me how to make forcefields like the one in hl2 where only bullets and grenades can pass?

thx

See if this can help get you started...

umm i mean like this one

I'm sure Nanodeath has it right for the part you can't see... I'm not sure how the visual effect is achieved though.

ya i cant find it in textures and nothing comes up when zapping it with impulse 106 & 107.

my only clue is the fence is prop_dynamic.

wll thx anyway

Just type in "combine" as a search filter and it's one of the options in that (long) list. Also...for the sound of it all I remember is that it contains the word "sheild" (sic).

Hmm...I think the shield is a prop, judging by the texture name/locations.

thank you dude!!! if i were gay i would kiss you!!!

Um? Yeah...right. Make sure it works first though, because it's technically a model texture and the game doesn't usually like that when you put those on brushes.

darn my bullets wont pass through my shied.

any suggestions?

Are you using a prop? Otherwise just make a func_brush out of the shield, set its Solidity to Never Solid, and then create another brush over the top of it and paint it with the clip texture.

make a func_illusioinary with the shield texture, then make a box the same size with the toolsplayerclip texture. VIOLA

func_illusionarys are obsolete...and it's "voila". Viola's an insrument :wink:

func_illusionarys obsolete? i think not. i use um all the time. well not ALL the time but yea know..

Check the help/description of it: they're obsolete. They might work ok most of the time, but personally I'm going to stick with what they want us to use.

i did the brush thing and it worked. i personally want to thank Nanodeath for being a genius and for his compassion for noobs. i salute u.

ok ok you're welcome, sheesh :smile: . and for IshKaBibble, I guess you're also right. I noticed some of the objects in the de_cobble source they provided are still func_illusionarys...so maybe there isn't THAT big of a reason to use one over the other shrug

In single player, create a brush and tie it to func_brush. Fill
in the class of the NPC that is allowed to pass through it, in the "NPC
Class excluded from collisions" field.

For deathmatch this does not work, so you can create a NODRAW brush and
tie it to trigger_push. You can assign a filter to the trigger,
only allowing certain things to pass through it. I use two
brushes for my forcefields. The first one pushes at a speed of
192 - so the player can hit it without being pushed back very much at
all ... and the second brush is set to a speed of 384 - so the player
does get pushed back quite a bit. I do this because if a
player sprints, their speed doubles and they can easily pass through a
trigger_push that has a push force of 192, and yet if they walk into a
trigger_push that has a force of 384, they are flung backward at a very
noticable speed.

For decorations, use models/props_combine/combine_fence01a.mdl and
models/props_combine/combine_fence01b.mdl on the sides .. they will
generate a forcefield effect.

It provides a pretty realistic forcefield - I suppose the only thing
that would be missing is that when the player hits the forcefield, the
get a buzzing sound, and the forcefield has an effect on it for a few
seconds ... the sound could easily be attached to the
OnStartTouch output, but you are on your own for how to display a
forcefield effect. The effect is in there under
effects/combineshield/comshieldwall but I have not figured out how to
use that yet.

Actually there's a prefab now that makes the shield quite nicely...

Now you tell me! Spent last 3 hours perfecting it for my new
tutorial example map ... hehehe Where is this prefab?
I could not find it in the files section.

If you look in the 'HL2 prefabs' that come with Hammer there should be
this forcefield. Thats where I got mine from anyhoo. Looks just like
the one your after and only lets bullets and grenades through... :smile:

Yeesh, it's easy! Make two prop_dynamics using the emitters mentioned above. In between, create a 1 unit-thick brush covered in an appropriate effects/ texture (for the visual effect) and tie it to either func_illusionary/func_brush, or func_wall_toggle if the field can be turned on/off. If you're mapping for single player, set this up as described above so Combine troops can move through it, or for DM stick a toolsclip brush over the top and you're done. The touch sound effect is also easy with a trigger_multiple, though set the 'fade out time' to 5 or so otherwise it doesn't sound realistic.
