Standalone [1.3] tModLoader - A Modding API

N o clu but what I believe that I did was delete my character manually and gave him all his stuff back...
[doublepost=1498107265,1498106718][/doublepost]I will be back in the morning. If someone can reply to both our ?'s that would be awesome.

I keep getting this message when I load up terraria and it goes through my mods.
Field not found: 'Terraria.Item.toolTip2'.
at TrueEater.GlobalTrueItem.SetDefaults(Item item)
at Terraria.ModLoader.ItemLoader.SetDefaults(Item item, Boolean createModItem)
at Terraria.ModLoader.Mod.SetupContent()
at Terraria.ModLoader.ModLoader.do_Load(Object threadContext)

And every time I click "Ok" to let it disable the mod. It just does it again. I did it for 10 mins strait once.

disable that mod, it's outdated.

I got a projectile (Named "CataclysmicLife") to spawn the "SpiritHeal" projectile upon hitting an NPC, but the SpiritHeal projectile does not heal me, even with the Spectre Hood equipped. Is there something I'm missing?
The mod loads fine, though. Here's the code:

You, sir, helped a ton :D
But one more (very nooby) question:
How do I change the Influx Waver Projectile to a custom/modded projectile?

Here's the code again:
Code: 
                Vector2 vector2_1 = new Vector2((float)((double)player.position.X + (double)player.width * 0.5 + (double)(Main.rand.Next(100) * -player.direction) + ((double)Main.mouseX + (double)Main.screenPosition.X - (double)player.position.X)), (float)((double)player.position.Y + (double)player.height * 0.5 - 600.0));   //This defines the projectile width, direction and position.
                vector2_1.X = (float)(((double)vector2_1.X + (double)player.Center.X) / 2.0) + (float)Main.rand.Next(-100, 100);
                vector2_1.Y -= (float)(100 * index);
                float num12 = (float)Main.mouseX + Main.screenPosition.X - vector2_1.X;
                float num13 = (float)Main.mouseY + Main.screenPosition.Y - vector2_1.Y;
                if ((double)num13 < 0.0) num13 *= -1f;
                if ((double)num13 < 20.0) num13 = 20f;
                float num14 = (float)Math.Sqrt((double)num12 * (double)num12 + (double)num13 * (double)num13);
                float num15 = item.shootSpeed / num14;
                float num16 = num12 * num15;
                float num17 = num13 * num15;
                float SpeedX = num16 + (float)Main.rand.Next(-12, 10) * 0.160f;  //This defines the projectile X position speed and randomness.
                float SpeedY = num17 + (float)Main.rand.Next(-12, 10) * 0.160f;  //This defines the projectile Y position speed and randomness.
                Projectile.NewProjectile(vector2_1.X, vector2_1.Y, SpeedX, SpeedY, type, damage, knockBack, Main.myPlayer, 0.0f, (float)Main.rand.Next(5));
                Projectile.NewProjectile(vector2_1.X, vector2_1.Y, SpeedX * 0.5f, SpeedY * 0.5f, ProjectileID.InfluxWaver, damage * 2, knockBack, Main.myPlayer, 0.0f, (float)Main.rand.Next(5));[/SPOILER]

Sure thing, here's how to get the type of a moded projectile:
Code: 
mod.ProjectileType("YourProjectile'sClassName")
This goes where you "have ProjectileID.InfluxWaver"

Looks like you need to set the SpiritHeal projectile's AI[0] to the ID of the player that you want to heal, and the owner of the projectile to the ID of the player who created the projectile. I havn't tested this though, so I don't know if it will work.

I personally prefer mod.ProjectileType<YourProjectileClass>(); but to each their own I guess.
 
Help!When i try host/join hosted server by my friend my game crash!What to do?(Steam,Linux)
Mods does not affect because even when I turn off all the mods the game again crash when i host...
And game starting at 2nd-3rd time with tmodloader...

It keeps popping up even after I click "ok" to continue to the menu.

Go to %UserProfile%/Documents/My Games/Terraria/ModLoader/Mods (paste this in your windows explorer path) and remove the TrueEater.enabled file
This should stop the file from loading
 
@blushiemagic You might want to catch some Exceptions during loading mods.
The reason for it is that I managed to get a NullReferenceException during loading one of my mods, which I wanted to update for the current version of tModLoader.
The Exception is not handled, since Terraria itself crashed and I can't identify why it happens since - because of the lack of handling - the application doesn't write it into the log.
I know it's nearly impossible (or isn't possible at all) to identify what code causes this mod-wise at runtime but we don't actually need that. A little hint on what has thrown the exception (in the application itself) would be enough.
 
Okay so I'm working on this mod and I already merged all my items to 0.10, however. whenever I try to reload it the game crashes without a trace... I have no idea how to fix this, any help? thanks in advance!

I guess that's what I was talking about in my previous post. It's hard to locate the source of the problem without logging, I'm also having this problem right now.

oh sorry I missed that, and yeah I tried just using a single item as a mod ( no dusts or projectiles or anything ) and it was still crashing... oh well
 
I don't think it's tModLoader itself, but after 10 minutes of playing my game will crash with no reason why. I've since downgraded to the previous version of all my mods and can run it fine. I don't know where my logs are or where/if i can find them, i did a clean wipe of everything. Could it be an unstable mod/bug that's causing my issue?
 
Hi, so I've been playing on a PC for the last couple days and had no problems, but today, I had to switch to my Mac and after installing tModLoader, my game freezes after the Re-Logic splash. I've tried using the .jar file and manually installing on two users and I've gotten the freeze every time except for one, and that was the first launch after installing. Is this just a thing? Please help.

How can i solve this ?
 
My game crashed after I talked to the guide, while using a gamepad. I think the fact that I was using a gamepad was the issue, since I saw it is the crash log.

The given key was not present in the dictionary.

I've gotten the same error while reloading mods with a gamepad connected. It's a bug that's been around for a while, though I haven't had it come up while speaking to the guide.
