Standalone [1.3] tModLoader - A Modding API

I need to access a variable i want to set with a hotkey, which will turn off and on the modded npc spawns for testing, but i dont know how i can access the main Mod file variable from another file, since i dont know what the instance the game makes is called. Any ideas?

Game crashes and this message pops up randomly while playing. Any idea what it means/how to fix it?

All modSomething classes have a reference to their mod class. You can cast that as the class of your mod class to get it from Mod to ExampleMod, for example.
 
How do I change this
return spawnInfo.spawnTileY < Main.rockLayer && !Main.dayTime ? 0.5f : 0f;
so it spawns in the day and night

Allright, could you show me your code then?
I might be able to help then.
 
If you would like to do a total conversion mod, would it be hard to have a mod that removes everything in the game except dirt/grass?
(Like flatworld setting in Minecraft).

Well not really you just have to make a worldgen that removes all the tiles and replaces them with a flat dirt/grass platform

Well not just the tiles, but remove every item/weapon/enemy/npc and so on.

Should be included as a mod in tModLoader.

Out of curiosity, why would you want to remove items? Wouldn't removing the means to acquire them be sufficient?

                    {
                    Item.NewItem((int)npc.position.X, (int)npc.position.Y, npc.width, npc.height, mod.ItemType("EyeOfCthulhuNMBossBag"));
                    return false;
                    }
                    return true;

Why is this working for the EoC, but not the King Slime?

So with public override void OnHitNPCWithProj(Projectile proj, NPC target, int damage, float knockback, bool crit), is it possible to check the type of damage the projectile does? I thought maybe something like this would work, but it gave me errors of course.

Code: 
public override void OnHitNPCWithProj(Projectile proj, NPC target, int damage, float knockback, bool crit)
        {
         if (lifeBloom)
            {
                if (proj.minion)
                {
                    if (Main.rand.Next(4) == 0)
                    {
                        player.statLife += 3;
                        player.HealEffect(3);
                    }
