[Code Sniplet] - Earthquake

[Wad'a'Holic]

Hey guys!
Screwing around with Fraggle-script one day and I made this. Hope it helps, one of the most effective ways to create an earthquake effect cos it shakes the object not the camera.



// Scripted Interaction : Object earthquake
int objectEarthquakeAmount;
script 71
{
while(objectEarthquakeAmount>0)
{
objmomx(trigger, 5);wait(5);
objmomx(trigger, -5);wait(5);
objmomy(trigger, 5);wait(5);
objmomy(trigger, -5);wait(5);
objmomz(trigger, 5);wait(5);
objmomz(trigger, -5);wait(5);
objectEarthquakeAmount--;
wait(1);
}
}



Add that to your script. Then when you want the earthquake effect to start, put this in...



objectEarthquakeAmount=5;
startscript(71);



NOTE: This script shakes the 'trigger' object, example, if a zombie walks over a line that activates the earthquake, he will shake and not the player. Please keep this in mind.

ALSO to keep in mind, you can change the objectEarthquakeAmount=5; to another number to change the earthquake shake time.

Hope to hear your comments and feedback on the effect. Free to use without credit :D

This was created by Darkwolf a year or two ago. Same idea, but note it uses the 'rnd' command to randomize things a bit.


/* Pseudo Earthquake
by DarkWolf */

[scripts]
include("things.h");

script 1
{
int tics;
fixed randx;
fixed randy;
fixed randz;
while(tics < 30) //desired seconds * 10
{
randx = (rnd() / 75) - 1.5; //should it be 'prnd' for demo compatability?
randy = (rnd() / 75) - 1.5;
randz = (rnd() / 200); //optional
objmomx(playerobj(0), randx);
objmomy(playerobj(0), randy);
objmomz(playerobj(0), randz);
wait(10);
tics++;
}
}
startscript(1);

I used Darkwolf method, but apart from shaking (the Z coordinate was a bit unstable so I removed it) it made you completely vulnerable.

Earthquakes are done best when it only shakes the screen I find. They are good for audio/visual cues that something has happened elsewhere in the level, barring they aren't overused.

[Danimetal]

That´s why we need Hexen stuff and that´s why we´ll probably have it... ´Cos Hexen had earthquakes, didn´t it?.

[DooMAD]

Yep, Hexen has a simple linetype for earthquakes. It must be an object shake, rather than just the camera, as it has no effect when you have no clipping on.

[Danimetal]

That will render all earthquake scripts useless... I would start some more Hexen editing if just DoomBuilder didn´t crash each time I use the Hexen format.
