Standalone [1.3] tModLoader - A Modding API

[Sin Costan]

I know I have asked this question already but... I've been stuck for a while making a projectile have gravity. I've done some research, but everything I tried has not worked. So how do you make a projectile have gravity?

Have you tried updating the projectile's velocity by adding 0.9f (If I recall the gravity constant in Terraria correctly...) to it like this in the AI portion of your projectile?

public override void AI()
{
   projectile.velocity.Y += 0.9f; //Positive is down and negative is up, forget the reason behind this though.
}

Hey, Ethan again. I was getting ready to play some modded Terraria with a couple of pals when one reported some errors occurring with The Thorium Mod. As far as I can tell, it's not with the mod itself, but rather with the way the sound is being used. Terraria sounds already refuse to work on his computer (sound & ambient sliders have no effect on sound, music slider just resets back to 0% whenever he changes it, we haven't found a fix), and I'm guessing that's what's causing it, as no one else has the problem. Here's the report:

An unexpected error has occurred.
at Microsoft.Xna.Framework.Audio.SoundEffect.AllocateFormatAndData(Byte[] format, Byte[] data, Int32 offset, Int32 count)
at Microsoft.Xna.Framework.Audio.SoundEffect..ctor(Stream stream)
at Microsoft.Xna.Framework.Audio.SoundEffect.FromStream(Stream stream)
at Terraria.ModLoader.ModLoader.LoadMod(TmodFile modFile, BuildProperties properties)
at Terraria.ModLoader.ModLoader.LoadMods()

Any ideas?

Edit: @bluemagic123 you there? Sorry to spam you requests for help, but I'm out of ideas here. We've tried everything there is.

Big dupe bug in multiplayer showing up with Chests and the Loot All button. If you have multiple slots filled with items, hitting the loot all button will give you all the items but reopening the chest will have all the items still there except the first slot that was previously filled. Can be repeated ad nauseam to achieve literally infinite of any item so far tested.

This seems like a server issue and there are NO mod items involved so I'm assuming this is the right place to make this known. Can anyone else confirm?

I can confirm this, because I believe I have found the bug that causes chests to act wacky. It might be tough for me to come up with an efficient solution, but I have a general idea of how to fix it.

I know it's nearly impossible but I would really really enjoy (along with a lot of players) having new dimensions in Terraria. It would greatly extend the game and open up a whole new world of options.

I was just curious if it was possible and what the logistics behind it was.

Any guide how to add world generation (ores)? Also my ModWorld seems to be broken:

        public override void SaveCustomData(BinaryWriter writer)
        {

Looks like you either have a pre 0.7.1 Terraria.exe or a pre 0.7.1 TerrariaMac.exe.

Here is ore generation:

        public override void PostWorldGen()
        {
            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("CoalOre"), false, 0f, 0f, false, true);
            }
        }

Is it possible to make an item or accessory that works as a substitute to a crafting material(like wood) but is never consumed?

So if I equip it I don't need wood in crafting at all. Like with Alchemy Station that reduces the amount of crafting items to be used by 33.3% but instead with a 100% reducion of a certain material.

I can't think of how to make that work.

I was just curious if it was possible and what the logistics behind it was.

Terraria has a 2d array of tiles that represent the world, and it is initialized to the size of the world. Where would the alternate dimension fix in there? How would a server handle 2 players being in different dimensions when in reality they are right next to each other.(Their X Y positions)

Anyway, I managed something like this before, but I never went farther with the idea since I was certain it would end poorly:

I don't think so, in the corner it says tModLoader 0.7.1.1.

 

[jopojelly]

I don't think so, in the corner it says tModLoader 0.7.1.1.

Yeah, but sometimes people don't copy in the TerrariaMac.exe when installing on windows because they don't understand that they need it. Try running the installer again.

I've been trying to get some aspects of my mod working on with a server. I've been using "Main.NewText("something");" and "Console.WriteLine("something else");" to see what does and doesn't happen, and I've noticed some odd things.

When I use an item, the UseItem hook isn't called on the owner in singleplayer or the owner's client in multiplayer, but it is called on the server and other clients. I've also noticed that the Shoot hook is only called on the client of the item's owner, but not other clients or the server.

Are these bugs or intentional behaviour?

The source code does some really weird things.

Because the UseItem hook is called on the server, it allows for things like NPCs to spawn. Because the Shoot hook is called only on the client, it allows for the projectile's owner to be easily set (and also makes it so that you can see what you shoot right away).

The endless quiver and pouch do that with certain ammo and Alchemy station with every crafting material.
