I was wondering if i could attach a particle to a player, and have it visible only to a certain other person. Or any effect for that matter. kinda like when you're dueling someone you can see the thingy floating over that person's head in tf2.

You might want to check with Mecha The Slag about this - he was working on achieving this functionality last December.

Failing that, PM me and we can talk about it. I have some theories but haven't had time to test them out.

SDKHooks' SetTransmit can do this.

And you'll need to use the attachables workaround to attach anything to a player for TF2.

2 problems, the transmit is not working, everyone can see the logo, tho i might be doing that wrong, just assuming thats how it works

Second, the logo is not removed when people die, respawn, change class....
tried Kill ent input, and remove edict on the death event and spawn event.

I remember others trying to use SetTransmit and they found it doesn't work on particle systems.

[BrutalGoerge]

poo, any ideas? ive never messed with this kinda stuff before. it doesnt have to be a particle, just something visible i guess

[Monkeys]

env_sprite would be the easiest to work with.

[BrutalGoerge]

sprites lookin good so far, they at least go away when i give them the 'Kill' entity input >
ill try out the transmit blocking later.

thanks

[Monkeys]

I tried that on HL2DM, and it seemed to work just fine as far as I can remember, so you shouldn't have any problems.

[BrutalGoerge]

yep it works.
im using OnGameFrame() to teleport the sprite to the player to 'attach' it, but lag compensation makes it look bad
without using that attachments workaround ext, is there a way to at least make it look somewhat better?
