The "How do I..." Thread

How do i get rid of that ?

I made fully working Sliding Door. Which should stay open after pressing switch.
Done... However when fully opened, part of wall disappears or becomes invisible so i can see part of polyobject and skybox through it.
Tried Google. Doublechecked sliding door tutorial. Nothing

The polyobject must slide in only one sector.

[Mart]

Checked : It is Sliding in one sector

[Remmirath]

From what i can see, when the polyobject is activated, it goes off the map. That produces that HOM. Draw another sector in which the polyobject will slide, like this:

Code: Select all

              
                       _______________________________
_____________|_______________
|____________|_______________| <--- Polyobject
                       |______________________________

Made sectors for Polyobjects.

Still nothing ...

Ill give a try to Split door. Already have one in map but ill try sliding one later again.

Thanks for help anyway.

Hy!

How do I freeze the game completely with ACS?

For example, I press use at a wall, some hudmessage or hudimage will be showed and all the enemies, projectiles, etc. will be freezed. I press use again, the text goes away and the game goes on as normal.

I found a Pause(); -topic and there was asked the same thing, but it was trounced down to be a useless and annoying feature.

I have a small question too.
How to make ACS variables work in Decorate?Example is A_Explode(Expl_Dmg,128) so in ACS i could fully modify it damage.

[InsanityBringer]

You can't: Use [wiki]ACS_ExecuteWithResult[/wiki] instead. Then, write a script that at some point calls [wiki]SetResultValue[/wiki] to set the value that will be returned by ACS_ExecuteWithResult.

So, in your script, do this:

Code: Select all

Script 46 (void)
{
    int dmg = random(1,128);
    SetResultValue(dmg);
}

Of course, your formula for getting damage is probably a lot more complex than that, but you get the idea. And then in the decorate:

Code: Select all

A_Explode(ACS_ExecuteWithResult(46,0,0,0),128)

Thousand thanks. Very useful i would try that out.

How do I freeze the game completely with ACS?

You can freeze all actors, meaning everything but geometry (moving platforms, doors and the like).

You'll have to use a little inheritence to make a [wiki=Classes:PowerupGiver]PowerupGiver[/wiki] with infinite duration (Powerup.Duration 0x7FFFFFFF), that gives [wiki=Classes:PowerTimeFreezer]PowerTimeFreezer[/wiki]. Use an [wiki=Built-in_ACS_functions#Inventory]ACS Inventory function[/wiki] to give your PowerupGiver when you want the world frozen. To unfreeze the world, use another function to take PowerTimeFreezer. (It is important that you take the power directly, NOT the giver, as all the giver does is give. )

[wiki]SetPlayerProperty[/wiki] (Player, APROP_FROZEN, 1) - This will keep the player from moving around. APROP_TOTALLYFROZEN will take it a tep further, so that they can't use anything but the menu and the+Use key. Make sure you unset the property before continuing! To unset them, use the exact same function but put a 0 in place of the 1. (Player is the number of the player you want to affect, if the player is calling the script though, I.E. by using a wall, you can just use 0 there.)

[Chronos]

Also i was wondering what arguments 1-3 in ACS_Execute do?And what script 1 (int x) do?

[cq75]

Arguments 1-3 are parameters passed to the function. For example, if you defined your script as

Code: Select all

SCRIPT 1 (int x)
{
print(s:"the number input from the function is " d:x);
}

and if set the linedef action to ACS_Execute(1,0,1,0,0)

the 1 value will be passed from the linedef action, and the script will print out "the number input from the function is 1"

as opposed to

Code: Select all

Script 1 (void)
{
}

which takes no arguments

The only use I can come up with for this is if you wanted several different switches to trigger a single script, but each with slightly different results.

[Chronos]

Some crazy results can happen if combine this with DECORATE.Too bad args can only be integer.
Other question.I just started researching SBARINFO and it's just not working.I copy/pasted example from wiki, changed some images for try.But nothing happens.I placed SBARINFO lump in root directory of my pk3.Is there something i've missed?

[cq75]

Is there a way to make moving platforms in zdoom, like in ROTT? My guess is something along the lines of declaring a Thing, and somehow defining its behavior to move back and forth.

[Caligari87]

Not really. Maybe with some 3D floor trickery in GZDoom, you could fake it... but as is, the engine just doesn't have the capability.
