Trigger_push underwater Created 4 years ago2019-12-29 23:37:44 UTC by _Vissova_

For some reason trigger_push doesn't work underwater (inside a func_water) but I could have sworn there was a map in Half-Life where you're pushed around underwater. I decompiled c2a4d and found several trigger_push brushes underwater but they don't work there either. Did Valve just never get around to making them work, and is there a workaround?

You can always make a wall that pushes if it is single player. Maybe also try func_illusionary with content water? Trigger push works within illusionary but if not it might have to do with the player swimming and not walking.

Is it undertow in Half-Life Deathmatch with the flowing water that ends at a waterfall?

there are those strange cur_ textures admer found out about

Those strange cur_ textures push waaaaaay too much (you end up reaching 3000 units/sec or so), I would advise against using them. :3

seems like undertow water only pushes you if you hold E, which seems strange. Cant remember if it always was like that

Tried increasing push speed? Modifying the pitch of the angle so that it points a bit upwards? Using func_conveyor for pushing? Triggering trigger_push on and off while inside it?

How do cur_ textures work? Where are they used?

They work as world brushes, but they push way too fast, tschumann.
I uploaded an example map to the Vault back in 2016.

I couldn't see any cur_ textures in Half-Life's .wad files so I guess they're not used in any official maps? Is there any documentation on them like http://www.the303.org/tutorials/gold_texture.htm?

The only documentation I was able to find is right here:

They can't do much though. Due to how compilers currently work, they exclusively only, and I mean, ONLY accept !cur_90, !cur_0, !cur_270, !cur_180, !cur_up, or !cur_dwn, so nothing in between, and no suffixes like !cur_90_lab.

Ah thanks - I'll have to take a closer look at the qcsg code.

Correction, the compilers should also accept !cur texture names with suffixes.

if (name[0] == '!') //optimized -- don't check for current unless it's liquid (KGP)
{
    if (!strncasecmp(name, "!cur_90", 7))
        return CONTENTS_CURRENT_90;
    if (!strncasecmp(name, "!cur_0", 6))
        return CONTENTS_CURRENT_0;
    if (!strncasecmp(name, "!cur_270", 8))
        return CONTENTS_CURRENT_270;
    if (!strncasecmp(name, "!cur_180", 8))
        return CONTENTS_CURRENT_180;
    if (!strncasecmp(name, "!cur_up", 7))
        return CONTENTS_CURRENT_UP;
    if (!strncasecmp(name, "!cur_dwn", 8))
        return CONTENTS_CURRENT_DOWN;

Location: VHLT v34, HLCSG, brush.cpp, TextureContents()

According to the code here, the compilers check for the first several characters in the texture name.
So longer names like !cur_90_alternate will also work.
