how do I change the player's mass in game?

What's the least glitchy way to make a blow-away wall?

How so? Some random explosion graphics and a wall lowering? Or LITERALLY shoot a rocket into some dummy-physics sprites and have them blow away?

For the first option for some explosion graphics, make a trip line (wherever you want) that activates an ACS script that spawns explosive sprites (you'll need to make your own actors) everywhere, quake the floor, and lower it.

Is it possible to have monsters not detect the player by touching? For example, monster is facing North, player approaches from South. He "rubs" up against the back of the monster's radius but is never in its line of sight. It detects him from the touch alone and goes into chase/melee/missile states etc. Are there flags or other ways in which to make monsters only detect you by sight?

I'm afraid there is no way to do it, but, if I'm correctly, this a nice feature to suggest. Maybe as a flag for A_LookEx.

Thanks!

Is there a way to prevent player from being able to crouch only a specifically parts of the game? I mean, to prevent it by an ACS scrpit, and then allow it again?

Yes.

No.

[Ravick]

But this will disallow in the whole game. There is no way to disallow it just in a specifically moment?

[edward850]

Try "map", not "whole game".

There is no way to disallow it just in a specifically moment?

No. Well, you can disable player movement outright, but it's probably not what you want.

Is it possible to confine the player's mouse movement to a box?

[Ravick]

You say the the vision of the player, or even the movement of the mouse in the menus? If you are saying just the vision, you can make an ACS script that checks for player's angle and pitch and does not allow these values to get bigger and/or smaller the values you want.

@edward850 Thanks anyway =/

Hello!

Is there a way to speed up spikes in Hexen?

[ChronoSeth]

Is there a way to speed up spikes in Hexen?

Uh, what spikes?

Probably these: [wiki]Classes:ThrustFloor[/wiki]

And, yes, you could probably speed them up by inheriting from them and using shorter frame durations.

Thanks.

Oops, sorry, I didn't see you reply before

I've take a look at Enjay & Aphoterm's scripts for that chain-gun in Liberation. I thought it was very complicated, so I decided to make one simpler for my needs.

Here is the code:

Code: Select all

int Angulo;
Int Visada;

Script 405 (void)
{
 angulo = (getactorangle(1000) >> 8);
    if ((angulo > 64) && (angulo < 192))
     {
        if (angulo < 128)
         {
            setactorangle(1000, 0.25);
         }
        if (angulo > 128)
         {
            setactorangle(1000, 0.75);
         }
     }
 //Pitch
  Visada = (GetActorPitch (1000) >> 8);
    if (Visada > 20)
     {
         SetActorPitch (1000, 20<<8);
     }
     if (Visada < -20)
     {
         SetActorPitch (1000, -20<<8);
     }
delay(1);
restart;    
}

The values are arbitrary, so you'll need to define what numbers you want first. You'll need 4 values: the max and min pitch, and the max and min angle.

For doing this, first make a script that constantly shows the value of a variable with "[wiki]PrintBold[/wiki]". Then, make it give this variable the value of players angle (something like "MyVar = ([wiki]getactorangle[/wiki](1000) >> 8);"). Then run the game and watch the values that are displayed. Take the max and min angle values. Later you just need to take the values of the pitch, so just delete the line above and change for this: (MyVar= ([wiki]GetActorPitch[/wiki] (1000) >> 8);). Run the game again and take the values you want.

Note that in the script I give the angle and pitch variables the names of Angulo and Visada. Then I make it check if it is out of the range I want, and tell the ACS to give the player (TID 1000) the change it's angle and/or its pitch.

This is not an elegant way to do this, but it works, hehe
