Changing player properties dynamicaly in zscript

[insightguy]

Is it possible to change actor properties, specifically player's? I tried using variables but since I can't initialize them on the same line I declare them, it throws an error.

The goal here was to ensure that I can change player speed on specific inventory and conditions but I have other plans.

It is possible (and speed specifically is a simple "speed=0.0001" or whatever) but it really depends on what exactly you're trying to do and there's no way to figure out why you'd be getting an error without more information.

I'm trying to dynamically adjust the following:

Code: Select all

Player.ForwardMove (value here);
Player.SideMove (value here);

from both interacting with specific actors with the use key or if another actor has specific booleans triggered true or false.

initially, I thought of replacing (value here) with double variable like so:

Code: Select all

double test = 4.0;
default{
    Player.ForwardMove test;
    Player.SideMove test;
}

and be able to manipulate the variables like this

(What I wanted to achieve, will most likely not work)

Code: Select all

override bool used(Actor user)
	{
		holdCounter++;
		user.A_GiveInventory ("WeaponInstall" , 1);
		user.test = 1.0;
		if(holdCounter >= 100)
		{
			user.A_TakeInventory ("WeaponInstall" , 0);
			Super.touch(user);
		}
		if (user.player) { user.player.usedown = false; } 
		return true;
	}

but as variables can not be initialized after declared unless it's a constant or meta, which defeats the point, how do I get around this?

You must use

Code: Select all

actor class name which have new defined variable(pointer to actor with that variable). variable name

if you define new variable on any actor.
Because, in simple, engine know about existing of this new variable on/at new actor class, but require from you to confirm that you mean this right variable on this actor. Or something like that.


It just works this way...

What is the specific desired end result?


EDIT: If the need is to just modify the player's forwardmove and sidemove, the variables are playerpawn.[forward/side]move[1/2], 1 being walk and 2 being run:

Code: Select all

class foof:explosivebarrel
{
    bool togged;
    override bool used(actor other)
    {
        let pp=playerpawn(other);
        if(pp)
        {
            if(!togged)
            {
                A_Log("stupid speed enabled");
                togged=true;
                pp.sidemove1=0.1;
                pp.sidemove2=0.2;
                pp.forwardmove1=3.5;
                pp.forwardmove2=0.3;
            }
            else
            {
                A_Log("stupid speed disabled");
                togged=false;
                pp.sidemove1=1.;
                pp.sidemove2=1.;
                pp.forwardmove1=1.;
                pp.forwardmove2=1.;
            }
        }
        return false;
    }
}

oh so THAT's how you do it, I was wondering if I did somethign wrong, I thought the variable was just playerpawn.[forward/side]move. I forgot 2 varables can be stuffed in the thing, is there a list of these somewhere I can find?

EDIT: Never mind, found it in player pawn, thanks for pointing me in the right direction, too bad there is none for crouch height.

Thanks matt! Crab walking gun mode here I come!

This was meant to disable movement when interacting with the item, interaction works, just not the disabling movement part. But i've had more ideas with the concept and wanted to know how to manipulate player variables

Also, what does foof: do to the barrel?

That's the class name and the inheritance symbol.

I only knew where to find that because when PlayerThink() was first ported to ZScript I spent a lot of time going through the GZDoom source on Github to find out what did or did not affect movement.
