Wind

[Nanami]

Can wind not be changed in-game?

I want to change the wind occasionally, but the wiki says Sector_SetWind is only valid during initialization. I looked but didn't see anything else regarding wind that would help. Any ideas?

You can change it in-game as long as you use a script for the task. If you just put the special on a line, then it will take effect immediately when the level loads.

I'm having no luck with

Code: Select all

Sector_SetWind(0,windstr*100,winddir,0);

(where windstr is a random number between 1 and 20 and winddir is a random number between 0 and 255)

The parameters are slightly different in a script:

Code: Select all

Sector_SetWind( tag, amount, angle )

You're using a tag of 0, so it won't change the wind for anything.

[Nanami]

Well I'm wanting it to change the wind for sector 0 (so it changes on basically the entire map; I'm already changing light levels of the entire map like this).

But even if I make the entire map tag 1 and change the script, I still don't experience any wind.

[randi]

You have wind enabled in the sectors, right?

[Nanami]

Aha, my apologies, I've never used wind before so I didn't know there was a "wind" tag.

Fixed. ;)

Shouldn't Sector_SetWind automatically set the wind flag? Normally it's safe to assume if someone sets wind for a sector that he wants wind, no matter whether the sector was flagged or not. Unlike Boom this can be much easier controlled with ACS.

[Nanami]

Actually, in my case, I only set the wind flag for the outdoor areas (all the map is tag 0, but I don't want wind indoors!). So it should be fine the way it is.

On a side note, is there a way to keep the player from being affected by wind? I'm trying to get a few objects to move around from wind, but the player moving is just a tad silly, especially since even with a wind value of 20 I can't noticably see the objects move much, but the player moving is quite noticable.

1. Do your objects have the WINDTHRUST flag set? Without that they won't be affected by wind.
2. If you want the player not to be affected you have to clear this flag with Dehacked.


Furthermore, how about an actor property APROP_WINDTHRUST? There may be occasions where you may want to toggle this inside the game for certain objects.

[Nanami]

Yes, my objects have them. It's noticable with winds of 100, 200, but of course, even around 20 it moves the player too much for my liking.

[Graf Zahl]

It doesn't move the player any more than the other objects. The feeling is purely subjective but I have to agree.

One level where the wind really got on my nerves was LTSD E4M5 so I reduced its force by 30%. The awful handling of wind in Doom is caused by the fact that it only affects an object's momentum and doesn't take friction and mass properly into account. To be blunt, I think that Boom's wind was a pathetically poor implementation that is close to useless. I haven't seen a single level that made good use of it (and that includes Heretic's wind which uses the same basic method.)

[Nanami]

Also... how do you "clear" a flag like WINDTHRUST in DeHacked? I know how one would do it in DECORATE, but I can't get it to work in DeHacked.

[Graf Zahl]

You have to set the following:

MF2_SLIDE, MF2_PASSMOBJ, MF2_PUSHWALL, MF2_FLOORCLIP

[Chilvence]

Yeah, you cant clear a flag as far as I know, but you can reset the flags completely and leave out the ones you dont want.
