How to reduce the volume in a custom sound?

HTML:
using Microsoft.Xna.Framework.Audio;
using Terraria;
using Terraria.ModLoader;

namespace WeaponsMod.Sounds.Items.Weapons.Grenade_Launcher
{
    public class Shoot : ModSound
    {
        public override SoundEffectInstance PlaySound(ref SoundEffectInstance soundInstance, float volume, float pan, SoundType type)
        {
            soundInstance = sound.CreateInstance();
            soundInstance.Volume = volume * .5f;
            soundInstance.Pan = pan;
            soundInstance.Pitch = -1.0f;
            return soundInstance;
        }
    }
}

EDIT: Why adding a custom sound with this method:

HTML:
Main.PlaySound(SoundLoader.customSoundType, projectile.position, mod.GetSoundSlot(SoundType.Custom, "Sounds/Custom/Weapons/Grenade_Launcher/Impact1"));

Only work (play the custom sound) in a folder called "Custom"?

Looks like you didn't copy the file tModLoaderMac.exe to the ModCompile folder inside Terraria's folder.

So I followed the instructions to a T. Now my worlds don't show up in the menu. Just try again witht eh copy, right? Nope. The executable it uses downloaded it into my main game AND my copy. :\

Only way I can see my saved worlds right now is by starting the terraria app from inside the steam folder, which I can only presume will cause problems of some sort.

Whats going on and how can I fix it?

Thanks in advance.

BTW, it would be a lot easier to figure out what was changed in my files, but the "last modified" info says it was last modified 12/24/16. Does that mean anything...?

Hmmm, do you think you can make it such that we can see when was the mod last updated by us with a date? Oh yeah, good job on this, modding made easy for Terraria players.

Little Question.
is there a Option to show what Item is from what Mod?
It is quite hard to Tell if you just throw yourself at a Modpack.

I cant seem to access the modbrowser to any extent, in the latest release, it doesnt show anything, and if i load older ones it just crashes terraria - Is there any setup needed to use the Mod Browser?

Do you mean filtering mods based on their update date in the mod browser?

I've narrowed the pick up glitch (for me) down to either basic elemtal additions or elemental weapon enhancements, idk about the projectiles yet
Yeah don't use EWE (elemental weapon enhancements) I haven't touched it in a long time now lol.

I am trying to make a fruit that when you eat it i get a debuff saying i am full and i also want it to heal 35 life. how would i make that happen? (i also want to not be able to eat the fruit if the full debuff is active)
To heal you could set item.heal = 35 in its SetDefaults, you can do player.AddBuff() in the UseItem hook to add your buff.

I am very glad to help lol, and I think the mod that caused projectiles not to work was imksushi but I'm not positive.
