After, you can go classic loop:

Code: 
public override void FindFrame(int frameHeight)
{
int height =  51;  //(height of the sprite for me, rarely equals to hitbox)
npc.frameCounter --;
if(npc.frameCounter < 0){
npc.frameCounter=60;
npc.frame.Y = (npc.frame.Y+height) % height* 3; //3 or Main.npcFrameCount[npc.type]
npc.spriteDirection = npc.direction;
}
if(npc.velocity == Vector2.Zero) npc.frame.Y=height*2
}

After, i am not sure.
I see a thing, also, you need maybe add others things if your ninja have velocity == Vector2.Zero where always you take the 3th frame.
Sorry if i have mistake.

But when I do that, the ninja stays in 1 animation only now. Foot-up.

Hum, strange, can he do not move, he go frame n°3 and when he move, he walk normally...

I have fix thing and change also, normally, this thing is functionnal: Else, this is maybe you have forgot a thing in setdefault... or maybe a other guy for help me.
Code: 
        public override void FindFrame(int frameHeight)
        {
            if (npc.velocity.X == 0) npc.frame.Y = frameHeight * 2;
            else
            {
npc.spriteDirection = npc.direction;
                npc.frameCounter--;
                if (npc.frameCounter < 0)
                {
                    npc.frameCounter = 30;

                    if(npc.frame.Y == 0 ) npc.frame.Y = frameHeight;
                    else npc.frame.Y = 0;
                  
                }
            }
        }
If npc do not move: frame n°3 else if move : he go frame n°1 then n°2 then loop. I have put npc.spritedirection when he move because i think, this is maybe less ugly.

public override bool Shoot(Player player, ref Microsoft.Xna.Framework.Vector2 position, ref float speedX, ref float speedY, ref int type, ref int damage, ref float knockBack)

How to make it shoot 2 things and not far from eachother?
[doublepost=1467309917,1467309895][/doublepost]3 things*
 
You want a Clockwork Assault Rifle ? So?

This is very simple, i link with my weapon:
Code: 
            item.useTime = 3;
            item.useAnimation = 60;
            item.autoReuse = true;
useTime for distance between two shoots.
useAnimation , just for animation, you take useTime* cooldown (ths is 20 here for my weapon).
autoReuse = true, or false, but prefer true.

Then:
Code: 
public override bool Shoot(Player player, ref Vector2 position, ref float speedX, ref float speedY, ref int type, ref int damage, ref float knockBack)
        {
       
            if (time <= 3)  // Number of waves of shoot  (3, so 3 waves)
            {
                      // YOUR SHOOT
            }
            else if (time >= 20)    // "Cooldown"
            {
                time = 0;  // reset to 0
            }
            time++;
            return false;
        }

This is very simple ^^.


EDIT: You can put false for AutoReuse.

You're looking at the wrong class, your error is in HighVoltageArrow, not ElectroBolt.

Either way, you probably forgot to make HighVoltageArrow a child of ModItem.
 
I fixed that problem, thanks. Anyways can you please help me make my projectile inflict the vanilla debuff "Electrified" to enemies?
 
And I want to be able to spawn more than 1 type of modded ore, but I don't know how, here's my code:
Code: 
using System.IO;
using System.Collections.Generic;
using Terraria;
using Terraria.ID;
using Terraria.ModLoader;
using Terraria.World.Generation;
using Microsoft.Xna.Framework;
using Terraria.GameContent.Generation;

namespace TacticalMod
{
  public class ModWord : ModWorld
  {
  private const int saveVersion = 0;
  public override void ModifyWorldGenTasks(List<GenPass> tasks, ref float totalWeight)
  {
  int ShiniesIndex = tasks.FindIndex(genpass => genpass.Name.Equals("Shinies"));
  if (ShiniesIndex == -1)
  {
  return;
  }
  tasks.Insert(ShiniesIndex + 1, new PassLegacy("Growing Sulfur", delegate (GenerationProgress progress)
  {
  progress.Message = "Growing Sulfur";
   
  for (int k = 0; k < (int)((double)(Main.maxTilesX * Main.maxTilesY) * 6E-05); k++)   
  {   
  WorldGen.TileRunner(WorldGen.genRand.Next(0, Main.maxTilesX), WorldGen.genRand.Next((int)WorldGen.worldSurfaceLow, Main.maxTilesY), (double)WorldGen.genRand.Next(3, 6), WorldGen.genRand.Next(2, 6), mod.TileType("Sulfur"), false, 0f, 0f, false, true);
  }
  }));
  }

  }
}

For that, you go in your modplayer:
And add:
Code: 
        public override void OnHitNPCWithProj(Projectile proj, NPC target, int damage, float knockback, bool crit){
            if(mod.ProjectileType("HighVoltageArrow") == proj.type) target.AddBuff(buffid, time, true);
        }
Like, this is a modded projectile, this is more simple ^^.

For your second problem, i have never create ore, so i cannot help. But:

Code: 
public override void ModifyWorldGenTasks(List<GenPass> tasks, ref float totalWeight)
{
int ShiniesIndex = tasks.FindIndex(genpass => genpass.Name.Equals("Shinies"));
if (ShiniesIndex == -1)
{

} else{
tasks.Insert(ShiniesIndex + 1, new PassLegacy("Growing Sulfur", delegate (GenerationProgress progress)
{
progress.Message = "Growing Sulfur";

for (int k = 0; k < (int)((double)(Main.maxTilesX * Main.maxTilesY) * 6E-05); k++)
{
WorldGen.TileRunner(WorldGen.genRand.Next(0, Main.maxTilesX), WorldGen.genRand.Next((int)WorldGen.worldSurfaceLow, Main.maxTilesY), (double)WorldGen.genRand.Next(3, 6), WorldGen.genRand.Next(2, 6), mod.TileType("Sulfur"), false, 0f, 0f, false, true);
}
}));
}
int ShiniesIndex2 = tasks.FindIndex(genpass => genpass.Name.Equals("Shinies2"));
if (ShiniesIndex2 == -1)
{
return;
} 
tasks.Insert(ShiniesIndex2 + 1, new PassLegacy("Growing Sulfur2", delegate (GenerationProgress progress)
{
progress.Message = "Growing Sulfur2";

for (int k = 0; k < (int)((double)(Main.maxTilesX * Main.maxTilesY) * 6E-05); k++)
{
WorldGen.TileRunner(WorldGen.genRand.Next(0, Main.maxTilesX), WorldGen.genRand.Next((int)WorldGen.worldSurfaceLow, Main.maxTilesY), (double)WorldGen.genRand.Next(3, 6), WorldGen.genRand.Next(2, 6), mod.TileType("Sulfur2"), false, 0f, 0f, false, true);
}
}));

}

This thing is not functionnal?
 
just gives me this stupid error:

If you just copy/paste my code, you have not see ? x) I have just give code for
public override void ModifyWorldGenTasks(List<GenPass> tasks, ref float totalWeight)

Not for your class/modworld ^^'


If you do not found, you know than you need close a { after open? You have not close many thing, here x)

            return false;
        }

This is very simple ^^.


EDIT: You can put false for AutoReuse.

Just so you know, that can be done easier:
Code: 
item.useTime = 5;
item.useAnimation = 20;
// So 20 / 5 = 4 = will shoot 4 times in 20 ticks.
item.reuseDelay = 20; // Will take 20 ticks after the animation has ended to be reused.

ExampleMod, dude. ExamplePlayer is the modplayer. (Without, you cannot have custom minion or buff add per a armor ^^')

After, if your projectile is a custom projectile, you can change in the projectile:
Example(never forgot for player versus player!):
Code: 
        public override void ModifyHitNPC(NPC target, ref int damage, ref float knockback, ref bool crit)
        {
            if(Main.rand.Next(10) == 0) target.AddBuff(39, 120);
            base.ModifyHitNPC(target, ref damage, ref knockback, ref crit);
        }

        public override void ModifyHitPvp(Player target, ref int damage, ref bool crit)
        {
            if (Main.rand.Next(10) == 0) target.AddBuff(39, 120);
            base.ModifyHitPvp(target, ref damage, ref crit);
        }
 
Code: 
using System;
using Terraria.ID;
using Terraria.ModLoader;

namespace Items_Extended.Items.Weapons
{
    public class GoldenEye : ModItem
    {
        public override void SetDefaults()
