tAPI [Tutorial] Summoner Weapon (Programming knowledge required)

Everybody · Feb 28, 2015

Hola, I'm trying to make a Sniper Summon who has Frost Hydra AI, but shoots a certain bullet.

int attacking = -1;
for(int k = 0; k < 200; k++)
{
if(Main.npc[k].active && !Main.npc[k].dontTakeDamage && !Main.npc[k].friendly && Main.npc[k].lifeMax > 5)
{
float monsterX = Main.npc[k].position.X + (float)(Main.npc[k].width / 2);
float monsterY = Main.npc[k].position.Y + (float)(Main.npc[k].height / 2);
float monsterDist = System.Math.Abs(projectile.position.X + (float)(projectile.width / 2) - monsterX) + System.Math.Abs(projectile.position.Y + (float)(projectile.height / 2) - monsterY);
if(monsterDist < moveDist)
{
if(monsterDist < moveDist && Collision.CanHit(projectile.position, projectile.width, projectile.height, Main.npc[k].position, Main.npc[k].width, Main.npc[k].height))
{
moveDist = monsterDist;
moveToX = monsterX;
moveToY = monsterY;
attacking = k;
}
}
}
}
moveDist is the distance from the distance from the nearest monster your projectile can see; moveToX and moveToY specify the location of this monster; and attacking is the index location of the monster in Main.npc.

Where do i put this piece of code?
also, you haven't really said where any of these should be so it's kind of hard to figure out :guidestraightface:

You'd put that in the AI method, where the comment says to do what the minion what normally do (attacking enemies or following the player).

Does anyone know how to give a buff to the player when they have a helmet equipped and also (at a different time) have a full armor set on?

Now that r15 for tAPI has finally been released, I've updated my tutorial. Basically, a bug was fixed so that we don't need to manually despawn minions anymore. This means that we don't need a ModItem class anymore, so that's less source code we need to copy!

Now to wait for the same bug to be fixed with Damage...
Also, I recognized that the AI part (ModProjectile) of the tutorial was a bit lacking, so I included a link to my NPC AI tutorial, since NPCs and projectiles are very similar.

Also I finally get to use the thread changelog I had at the end of the post, lol

Less hard code?

To be honest, the code doesn't really become any easier; we just don't need to copy over a bunch of source code anymore to free minion slots.

Question: If I want it to be that when you crit, you get 1 of 5 buffs, will this code work?

Code:

using System;
using System.Collections.Generic;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;

using TAPI;
using Terraria;

namespace Terra.Items
{
    public class MonadoShield : ModItem
    {
    public override void DamageNPC(Player p, NPC n, int hitDir, ref int damage, ref float knockback, ref bool crit, ref float critMult)
    {
        if (crit)
            {
            if (Main.rand.Next(5) == 0)
            {
                p.AddBuff("Terra:MonadoJump",420,true)
            }

            else
            {
                p.AddBuff("Terra:MonadoSpeed",420,true)
            }

            else
            {
                p.AddBuff("Terra:MonadoShield",420,true)
            }

            else
            {
                p.AddBuff("Terra:MonadoBuster",420,true)
            }

            else
            {
                p.AddBuff("Terra:MonadoSmash",420,true)
            }
            }
    }
    }
}

            }
            }
    }
    }
}

It looks like you have the right idea; it's just the syntax that's incorrect. Specifically, this part of the code:

Code:

if (Main.rand.Next(5) == 0)
            {
                p.AddBuff("Terra:MonadoJump",420,true)
            }

            else
            {
                p.AddBuff("Terra:MonadoSpeed",420,true)
            }

            else
            {
                p.AddBuff("Terra:MonadoShield",420,true)
            }

            else
            {
                p.AddBuff("Terra:MonadoBuster",420,true)
            }

            else
            {
                p.AddBuff("Terra:MonadoSmash",420,true)
            }

What you want to do is assign the random number to a variable, then use that variable either in an if/else chain or a switch statement, like this:

Code:

int choice = Main.rand.Next(5);
if(choice == 0)
{
    //add your buff
}
else if(choice == 1)
{
    //add a different buff
}
else if(choice == 2)
{
    //etc.
}

All the way to if(choice == 4). If you want to use a switch statement instead, then it would work something like this:

Code:

int choice = Main.rand.Next(5);
switch(choice)
{
    case 0:
        //add your buff
        break;
    case 1:
        //add a different buff
        break;
    case 2:
        //etc.
        break;
    case 3:
        //etc.
        break;
    default:
        //this is the last choice
        break;
}

Testing it right now. Hope it works!

Hm, it's hard to tell. Did you try copying over the Damage() source code and removing the first two if statements? Also, did you try making sure projectile.friendly is true when it is attacking?

Friendly is set to true.

Have you tried setting the projectile's damage directly in the AI? For example...

Code:

public override void AI()
{
      projectile.damage = 10;
}

Just whatever name you want. For example, I use BluemagicPlayer since it's easy for me to remember.
