Disease through weapon projectile

[Saularian]

As alpha 9 added the vommiting effect, I thought it would be fun if tribals could use blowing pipes with poisonous darts that have an immediate illness effect. Or even have their arrows dipped in poison (or sharp weapons that have poison added to them). As I'm slumped on how to implement a disease type to a damagetype, I was wondering if anyone else has any ideas on that or how to do it. It could probably also  be used in tear-gas grenades, as this also has a nauseating effect

I hope someone can help me with this, as I'm a bit lost on how to do this, if at all even possible...

Create a new damagedef that applies a new hediffstaged and make the projectile use that damagedef. Think that would work. If not ill look into it when i get home later.

[Saularian]

Hmmm.... I think I'm doing something wrong, I'm getting a cannot apply exceprion....

So something is amiss, as it seems I'm trying to apply something onto the whole body, but it can't as it is treated as a local injury...

Or I'm just messing something up that is quite obvious but easily overlooked by me

[skullywag]

hediff_staged not localinjury, check hediffs_misc.xml in core for the crypto sickness hediff, it might help.

[Saularian]

Well, that was actually one of the first things I've tried,

            </actMods>
          </modifiers>
        </li>
      </severityStages>
    </stagedProps>
  </HediffDef>

But, this does not work as the worker class tries to apply a damage to a part of the body,

Code Select Expand

<workerClass>DamageWorker_AddLocalInjury</workerClass>

instead of the whole body as damageworker_Addglobalinjury does... but that workerclass is also not able to "apply" a staged effect on a pawn. Or I'm just completely unaware of a workerclass that would allow a projectile to do a damagedef that applies such an effect

[skullywag]

Ive just done this but via c# (slime poison bullet in my purpleivy mod im updating), as you state the default bullet class needs to hit a bodypart so its c# or nothing im afraid.

[Saularian]

Yeah, and explosive class also has the same problem, (no tear gas it is then... ) it checks bodyparts instead of the body
I was still wondering how

Code Select Expand

<infectionChance></infectionChance> can directly feedback into the

Code Select Expand

<HediffDef ParentName="DiseaseBase">
    <defName>WoundInfection</defName>
As this is pretty much the idea, although a bit more drastic and severe when poison is in play. If it is possible to add a second type of wound infection, that would be applied directly on impact, it could be used in the same way, although its a little workaround.

And c#... I can read and interpret it for the most part, but writing it is a whole different ballgame

[skullywag]

Ok here what we are going to do.  If you have visual studio go grab one of my weapons. Something like the railgun (it has custom projectiles) copy the  railgunDLL folder into your mod. Rename it and all files and folders where you see RailGunDLL to whatever your mods called (not required but tidier). Then open the yourmodDLL.sln file and it should open in VS. If you get this far drop me a pm and ill give you the next steps. This isnt hard trust me.

[skullywag]

so if youve managed to set up your dll stuff heres the code i reckon will work in the class:

Code Select Expand


protected override void Impact(Thing hitThing)
        {
            if (hitThing != null)
            {
              base.Impact(hitThing);
              //If we find a pawn
              if (hitThing.def.category == EntityCategory.Pawn)
              {
                  Pawn pawn = hitThing as Pawn;
                  HediffDef poison = HediffDef.Named("YourPoisonHeDiddDefName");
                  int damageAmountBase = this.def.projectile.damageAmountBase;
  BodyPartDamageInfo value = new BodyPartDamageInfo(null, null);
                  DamageInfo dinfo = new DamageInfo(this.def.projectile.damageDef, damageAmountBase, this.launcher, this.ExactRotation.eulerAngles.y, new BodyPartDamageInfo?(value), this.equipmentDef);
          hitThing.TakeDamage(dinfo);
                  pawn.healthTracker.AddHediff(poison, null, null);
              }
  }
      }



[Saularian]

YAY!

It now does what it is supposed to do


but it did throw me an exception when it misses it's target  And when I thought I fixed it, it throws me the exception when hitting the target (but still does the job )

[skullywag]

check the code i added a if not null check. make sure you have it.

[Saularian]

It's a null check reference...



I took out the parts that are not needed (the motes, the parts that added the graphical of the railgun ) to see if that would fix it, but the exception stays the same

[skullywag]

do you have the if hithing != null check as per the code posted above?

paste your impact method here.

[Saularian]

The only thing that made VS not build the solution was equipmentDef, that had to be changed to just equipment.

public class Projectile_SicknessBullet : Bullet
    {
        protected override void Impact(Thing hitThing)
        {
            if (hitThing != null)
            {
                base.Impact(hitThing);
                //If we find a pawn
                if (hitThing.def.category == EntityCategory.Pawn)
                {
                    Pawn pawn = hitThing as Pawn;
                    HediffDef poison = HediffDef.Named("ExtremeNausea");
                    int damageAmountBase = this.def.projectile.damageAmountBase;
                    BodyPartDamageInfo value = new BodyPartDamageInfo(null, null);
                    DamageInfo dinfo = new DamageInfo(this.def.projectile.damageDef, damageAmountBase, this.launcher,
                        this.ExactRotation.eulerAngles.y, new BodyPartDamageInfo?(value), this.equipment);
                    hitThing.TakeDamage(dinfo);
                    pawn.healthTracker.AddHediff(poison, null, null);
                    {
                        Messages.Message(pawn.Name.first + " " + pawn.Name.last + " was poisoned.", MessageSound.Negative);
                    }
                }

I think I'm missing something... Probably the part where it hit somthing other than a pawn

[skullywag]

try moving the base.impact outside that check?
