How can i make a projectile, that has a large image? A projectile that has a size of a building?
I am trying to make a mod, where large objects (like ancient ship part) fall from the sky. For that purpose i use mortar projectile and its code. Everithing works fine, but i cant make the projectile larger than 1x1. When i change the graphics of the projectile (used standard graphics for ship structural beam), it appear shrinked to the size of mortar shell. When i add <size> to the ThingDef, the game crashed at the time, that projectile should appear.
Is there a simple method to solve this? Without rewriting projectile draw code. Because, there is no example of it.
You need to rewrite object draw to make them bigger, but this is not that hard
public override void Draw()
{
Matrix4x4 matrix = default(Matrix4x4);
Vector3 s = new Vector3(num, 1f, num);
matrix.SetTRS(DrawPos + Altitudes.AltIncVect, ExactRotation, s);
Graphics.DrawMesh(MeshPool.plane10, matrix, CurBulletRad, 0);
}
Thats generally how i did my projectiles grow in radiation gun.
To change the size if you look at Vector3 s = new Vector3(num, 1f, num);
vector 3 uses x,y,z coordinates, since rimworld is 2d, y coordinate is always 1f, but as you can see my x and z uses num variable to change it size, and it works generally the same like the <size>
in xml. So having Vector3(1f,1f,1f) means that object will have 1x1 size.
Thats what i fear. I dont really understand code, i just copy paste from examples and change it. So, i copy your example and get errors: MeshPool, CurBullerRad does not exist in current context.
Should i replace it with something?
here my test code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using UnityEngine;
using RimWorld;
using Verse;
namespace CrushPod
{
public class Projectile_CrushPart : Projectile_Explosive
{
public override void Draw()
{
Matrix4x4 matrix = default(Matrix4x4);
Vector3 s = new Vector3(1f, 1f, 5f);
matrix.SetTRS(DrawPos + Altitudes.AltIncVect, ExactRotation, s);
Graphics.DrawMesh(MeshPool.plane10, matrix, CurBulletRad, 0);
}
protected override void Impact(Thing hitThing)
{
Explode();
}
protected override void Explode()
{
Destroy();
BodyPartDamageInfo part = new BodyPartDamageInfo(null, BodyPartDepth.Outside);
ExplosionInfo e = new ExplosionInfo();
e.center = Position;
e.radius = def.projectile.explosionRadius;
e.dinfo = new DamageInfo( def.projectile.damageDef, 999, launcher, part );
e.preExplosionSpawnThingDef = def.projectile.preExplosionSpawnThingDef;
e.postExplosionSpawnThingDef = def.projectile.postExplosionSpawnThingDef;
e.explosionSpawnChance = def.projectile.explosionSpawnChance;
e.explosionSound = def.projectile.soundExplode;
e.projectile = def;
e.Explode();
Faction fac = Faction.OfColony;
Pawn refugee = PawnGenerator.GeneratePawn( PawnKindDef.Named("Colonist"), fac );
GenPlace.TryPlaceThing( refugee, Position, ThingPlaceMode.Near );
BodyPartDamageInfo part2 = new BodyPartDamageInfo(null, null);
DamageInfo dinfo2 = new DamageInfo( DamageTypeDefOf.Stun,10,launcher,part2);
refugee.TakeDamage(dinfo2);
}
}
}
Maybe i forget to add using of something.
Sorry Curbullet is a variable for texture ;p
try this
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using UnityEngine;
using Verse;
using Verse.AI;
using Verse.Sound;
using RimWorld;
using VerseBase;
using RimWorld.SquadAI;
namespace MyModnamespace
{
class MyBulletClass :Bullet
{
public override void Draw()
{
Matrix4x4 matrix = default(Matrix4x4);
Vector3 s = new Vector3(1f, 1f, 1f);
matrix.SetTRS(DrawPos + Altitudes.AltIncVect, ExactRotation, s);
Graphics.DrawMesh(MeshPool.plane10, matrix, this.Graphic.MatAt(this.Rotation, null), 0);
}
}
}
And use Bullet insted of projectile_explosive, since this will give you acces to both projectile and projectile_explosive class
Yes it works! Thank you for fast reply.
