I recommend looking at the source code for the EoC but I think we aren't allowed to talk about it in forums so that's all I can say.Hey, is there a way to make your bosses dash at your player? I can't find any up-to-date ways to make my boss dash at me. Can anyone help?
Here is the code, if anyone wanted to re-make my situation. Here, my boss only shoots projectiles, and doesn't charge. I know I haven't added the charge code yet, but that's because I don't know how.
Code:using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using Terraria; using Terraria.ModLoader; using Terraria.ID; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Graphics; namespace BetterExploringMod.NPCs.Boss { [AutoloadBossHead] public class TutorialBoss : ModNPC { private Player player; private float speed; public override void SetStaticDefaults() { DisplayName.SetDefault("Icicle Guardian"); Main.npcFrameCount[npc.type] = 3; } public override void SetDefaults() { npc.aiStyle = -1; // Will not have any AI from any existing AI styles. npc.lifeMax = 2500; // The Max HP the boss has on Normal npc.damage = 15; // The base damage value the boss has on Normal npc.defense = 3; // The base defense on Normal npc.knockBackResist = 0f; // No knockback npc.width = 100; npc.height = 100; npc.value = 10000; npc.npcSlots = 1f; // The higher the number, the more NPC slots this NPC takes. npc.boss = true; // Is a boss npc.lavaImmune = true; // Not hurt by lava npc.noGravity = true; // Not affected by gravity npc.noTileCollide = true; // Will not collide with the tiles. npc.HitSound = SoundID.NPCHit4; npc.DeathSound = SoundID.NPCDeath1; music = mod.GetSoundSlot(SoundType.Music, "Sounds/Music/FrozenEyeMusic"); bossBag = mod.ItemType("TutorialBossBag"); // Needed for the NPC to drop loot bag. } public override void ScaleExpertStats(int numPlayers, float bossLifeScale) { npc.lifeMax = (int)(npc.lifeMax * 0.625f * bossLifeScale); npc.damage = (int)(npc.damage * 0.6f); npc.defense = (int)(npc.defense + numPlayers); } public override void AI() { if(Main.expertMode) { Target(); // Sets the Player Target DespawnHandler(); // Handles if the NPC should despawn.

Well, how would I do that? I don't know which variables to put in to make it face the player.I can't spot anything particularly wrong, but the code is long so I somewhat ignored most of it only focusing on the targeting part.
By "doesn't actually look at the player" do you mean the AI does not target them at all? Or do you mean the NPC's sprite does not face the player or rotate towards it depending on what kind of graphics you're working with.
In the first case, I would suggest to slap down a bunch of NewText printing your targetPosition's coordinates right after a value is assigned to it. So you can be really sure the targeting is working as it should, which would point the problem somewhere else (say, the AI movements for instance).
In the second case, you need to adjust the NPC's sprite to behave the way you want it to behave. I personally do it in the FindFrame hook, unless it has changed in recent ModLoader and I'm an old fart (which I am). Simple examples would include changing npc.rotation to face the targeted player, or flipping the sprite with npc.spriteDirection to face towards the target. This is also where you'd normally code the NPC's animation.
