lol welp I figured it out. for anyone who is trying to do the same thing paste this into your mobs file:

protected void attackEntity(Entity par1Entity, float par2)
    {
	    float f = getEntityBrightness(1.0F);
	    if (f > 0.5F && rand.nextInt(100) == 0)
	    {
		    entityToAttack = null;
		    return;
	    }
	    if (par2 > 2.0F && par2 < 6F && rand.nextInt(10) == 0)
	    {
		    if (onGround)
		    {
			    double d = par1Entity.posX - posX;
			    double d1 = par1Entity.posZ - posZ;
			    float f1 = MathHelper.sqrt_double(d * d + d1 * d1);
			    motionX = (d / (double)f1) * 0.5D * 0.8D + motionX * 0.2D;
			    motionZ = (d1 / (double)f1) * 0.5D * 0.8D + motionZ * 0.2D;
			    motionY = 0.4D;
		    }
	    }
	    else
	    {
		    super.attackEntity(par1Entity, par2);
	    }
    }

Edit: I figured it out but now I'd like to increase the length and height of the jump. Anyone know what I have to modify in the code below to adjust this?

This deserves more recognition.

wow, **** commas.

My mod returns tons of errors when I try to use more than 2 ingredients per recipe. If I limit it to two ingredients it recompiles just fine. Is there a limit to how many ingredients you can use in a recipe or am I just doing something wrong? Here's what my code looks like:

ModLoader.addRecipe(new ItemStack(daemonitePick, 1), new Object[]
				{
					"CDC", "MDM", "ADA", 'A', adamantinePick, 'D', puredaemonSoul 'C', cobaltPick 'M', mithrilPick
				});

I don't recommend editing ItemPickaxe. You should create your own ItemPickaxe and then make your changes in that. Just remember to make your tool class extend your new ItemNameherePickaxe.

Do you recommend the same for files like enumtoolmaterial and enumarmormaterial?

I've modded in about 6 new tiers of tools and added them to itempickaxe.java and enumtoolmaterial. I haven't changed the obsidian code at all:

if (par1Block == Block.obsidian)
		{
			return toolMaterial.getHarvestLevel() == 3;
		}

For some reason I can't mine it with any level of pickaxe, not even diamond. The only thing that solves this is if I remove the above line of code from itempickaxe. Does anyone have any idea why this is happening?

Try this:

public boolean getCanSpawnHere()
				{
								return true;
				}

Now mobs should spawn everyehere

wow this worked dude! thank you so much. have some imaginary internet karma.

This

protected boolean isValidLightLevel()

I have never worked with Mobs, but I'm quite sure. The other spawning condition is in EntityCreature.java and it is called getCanSpawnHere(). I think that changing this:

public boolean getCanSpawnHere()
		{
				return isValidLightLevel() && super.getCanSpawnHere();
		}

to this:

public boolean getCanSpawnHere()
		{
				return super.getCanSpawnHere();
		}

Should allow to spawn in the light. It would not prevent them from burning however.

Hope it helps

Hey I appreciate the help. Unfortunately it seems like it didn't work :(. What could be preventing them from spawning..

Hi can someone please point me to the right bit of code in entitymob that I need to change so mobs can spawn during the day?

That would require thousands of extra variables and flood the config file, it'd be a TON of grunt work for me to implement that and would probably bloat the code beyond all recognition. I put my money on it won't be happening.

Oh well not a problem. I really like your item sprites btw they look very cool.

can you control tool speed and durability in the config ile?

I'm using 2.0 btw and I tried it with 2.3 and it works. I'm guessing the problem is because I'm not using forge? Here's something from modloader:

Hey any idea why this is ncompatible with the Invasion Mod? http://www.minecraft...s-tough-do-you/
