Overgrowth Scripting Mods

[zalo]

I just took a look at the scripting behind Overgrowth, and it's so simple. It's just like Java or Actionscript. Here's what I did in 5 minutes:


Why don't I see more scripting mods around these parts?

I've been wondering about the same thing. There's lots of people here, but it seems like there are only very few scripters, programmers, drawers and 3d modelers.

A long, long time ago I did a few simple scripts to try out custom animations. Flips, flapping arms + flying, climbing animation that I activated manually before climbing up a steep surface etc.




Is your flying done by removing the counter from jump? Holding space -> up? I don't remember how I did my version, it's been such a long time. It probably didn't take much longer than yours. A real climbing code that'd automatically do stuff would be much more complex - have you looked at the ledge climbing code yet? ledgeup.as or something? After seeing that, I felt that whatever I had been doing was just silly magic tricks and now got a glimpse of real magic.


Also, there are a few limits to the scripting that might not be apparent at first glance. It's not documented, for one, so you need to find an example of how to do something before you can do it. That will come in time, and obviously it'd be silly to write a documentation when things can still change a lot.
Secondly, some things are done in the game-code, so we can't script it. More stuff will be added in time, as they start working on different parts of gameplay mechanics.
Thirdly, we can't tell if something is unimplemented as of yet, or just undocumented.

I haven't gone through all the new code yet, but I don't think it's possible to add a new object through code, or to have an existing game-world object as a variable. So you can't summon anything, can't create temporary things, can't shoot or throw anything, etc. Also, you can't change objects, so you can't have doors opening or traps being sprung or rabbit statues coming alive. However, we just got access to particles, which can be used to do some of those things. Rabbits breathing fire, here we come!

Actually, the flying was already in there, just very subtle. I modified a few variables so the "moving around in the air" effect was more pronounced, and since there was a mysterious "Jump_Fuel" variable, I decided to give that a couple extra zeros as well. The running speed was another variable. What you didn't see in my vid. was the slight modification to the AI guy's routine (enemycontrol.as) which contains all the AI for the guy.

Also, I agree with the lack of Documentation being annoying.

Argh, I couldn't get that firebreathing rabbits thing out of my head.


I used this in the .as:

Code: Select all

	MakeParticle("Data/Particles/fire.xml",this_mo.position+vec3(0,0.8,0),this_mo.GetFacing()*30);

And this as my fire:

Code: Select all

<?xml version="1.0" ?>
<particle>
    <textures color_map = "Data/Textures/smoke.tga" 
              normal_map = "Data/Textures/smoke_normal.tga"
              shader = "litsprite"
              soft_shader = "litspritesoft"/>
    <size min = "0.2" max = "5"/>
    <color red =   "1.0"
           green = "0"
           blue =  "0"
           alpha_min = "0.1" alpha_max = "5"/>
    <behavior inertia="0.95" gravity="-4.0" wind="0" size_decay_rate="0.0" opacity_decay_rate="0.0"/>
    <quadratic_expansion speed="2.0"/>
    <quadratic_dispersion persistence="0.5"/>
</particle>

I haven't had time to look at the particle interface yet. Which .as does that line go to? I assume it's aschar.as, since this_mo seems to mean a rabbit in this case.



The fire would have to be somewhat more orange, possibly modulating between red and yellow hues if that's possible. Having a gradient from white to dark red to orange to 10-30% transparent gray (smoke) would be better, but a adjusting the color by e.g. sin curves would probably be easier, and even that might still be impossible for modders.
Experimenting with different shaders could also help a lot, but I don't understand anything beyond the very simple stuff.

Never thought of scripting Overgrowth yet, but I will for sure mess around with it now. This is endless fun.

[pantokraator]

I used to script Mount&Blade a lot. Currently downloading the latest alpha, I'll see what I can do..

[Silverfish]

That's some really cool stuff zalo!
I'd really like to get into scripting for OG, but then I remember that my programming skills are quite limited and then I become sad.

And then I go into the script files and change numbers on random to see what happens in the game and then I become less sad.

If someone wants to make a mod some day I'll probably join to make models/animations/textures since that's what I can do.

I'd like to see more of this stuff!

The takeoff for Robbert look so damn cool. It reminded me of a hero springing into action. Awesome mod. I've been making super saiyan wolves recently using textures and particle effects, and would love to use them with a mod like this. Wolf Ball Z

[Silverfish]

Woah ss wolves! Awesome! xD
This engine would probably make a pretty great DBZ mod platform when it's out! ^^

[key2van]

Hey zalo, can i have the code try out the scripting mod? I really want to put in dragon ball z sounds and use it with the SS wolf alongside flying animations.

[zalo]

lol, there are no flying animations.

I just went into aircontrols.as and upped the Jump_fuel and air_control and jump_vel variables.

Apparently, the Wolfire team made jumping with this kind of expandability in mind.

EDIT: Oh, in aschar.as I upped the float_run_speed as well.

[key2van]

LOL, i know that there aren't any flying animations, i meant i would like to try this mod out alongside my flying animations. But thanks for the instructions, I am going to try this out soon.

[key2van]

I've been playing around with the scripts and I'm slowly getting better results, but one issue i have is with particles. I don't really know how to explain it properly, but is there any way to make the particles "refresh" as fast as the character runs or jumps? I'm not very good with programming as it was my least favourite course, so help would be greatly appreciated.

Every time I see "ss wolves" I think they're Nazis.
