You'd have to check what angle it wants to look at. This you would have to probably mess with quite a bit of code, probably from EntityLiving.java. What would do (similar to my car entity) is strip out the actionstates. Then make your own. You would have to code the AI for looking and walking in general. When it needs to change where it is facing, check to see if the desired angle would say be between (and look at my YAW code in my GUI to keep the number between 0 and 360 for ease of use) 225 and 45, and set the facing to 0. Do this for all 90 degree view arcs (or as specific as you want it), and set the rotationYaw to 0, 90, 180 or 270. I would leave the pitch at 0

amazing great, info . Ill try it

ah and PlayerAPI allows us to overwrite some functions inside EntityPlayer, without the need to change the main class. - Info that I obtained a week ago

I have my mob working now but a problem: my mob is almost alwys walking diagonally. (i can post pics if wanted)
his head turns toward me and the body is moving in the heads direction and not turning by itself and then walking straight forward.

Fly and Float down code

I'm a jerk. Ment to post the code on how I made the flying thing. Now this isn't how to make you fly, but you can probably work that out from what I show you. This is for flying creatures like the chicken.

I'll do the easy part first, adding some stuff for the animations. Just like with the legs and arms, on flight movement there is a float value passed to setRotationAngles, which is passed as f2. So if you wnat it to flap wings (or if you are creative, a cape flapping, maybe a propellar spinning) set your wing parts like so:

	public void setRotationAngles(float f, float f1, float f2, float f3, float f4, float f5)
	{
		super.setRotationAngles(f, f1, f2, f3, f4, f5);
		foot1.rotateAngleX = leg1.rotateAngleX - 0.2617994F;
		foot2.rotateAngleX = leg1.rotateAngleX - 0.2617994F;
		rightwing1.rotateAngleZ = f2;
		leftwing1.rotateAngleZ = -f2;
		body.rotateAngleX = 1.134464F;
		tail1.rotateAngleZ = MathHelper.cos(f * 0.6662F) * 1.4F * f1 * 0.5F;
		tail2.rotateAngleZ = -tail1.rotateAngleZ * 0.5F;
	}

ok im making a ufo mod but need to know how to make it fly and idk if this is the same HELP

Ok, now on to the flying part. Now I didn't play with this, as I was again making something like the chicken. later I may add some code to have it start to fly and maybe stay flying for a while. For now this was enough to show how it can be done. What we need is the onLivingUpdate() method from the chicken entity file. I will tell you that I am not versed enough in Java to understand some of the code (such as the line destPos += (double)(onGround ? -1 : 4) * 0.29999999999999999D; (though I think it's a mulitplier with a bolean test of on ground, yes being -1, no being 4). I do know that motionY is what we want to work with. here's the code I stole:

    public void onLivingUpdate()
    {
        super.onLivingUpdate();
        field_756_e = field_752_b;
        field_757_d = destPos;
        destPos += (double)(onGround ? -1 : 4) * 0.29999999999999999D;
        if(destPos < 0.0F)
        {
            destPos = 0.0F;
        }
        if(destPos > 1.0F)
        {
            destPos = 1.0F;
        }
        if(!onGround && field_755_h < 1.0F)
        {
            field_755_h = 1.0F;
        }
        field_755_h *= 0.90000000000000002D;
        if(!onGround && motionY < 0.0D)
        {
            motionY *= 0.59999999999999998D;
        }
        field_752_b += field_755_h * 2.0F;
        if(this.isInWater())
        {
        	posY += 1;
        	this.motionY += 0.5;
        }
        /* --subbed out from chicken code, but can have a timer to do something, like jump up and fly
        if(!worldObj.multiplayerWorld && --timeUntilNextEgg <= 0)
        {
            worldObj.playSoundAtEntity(this, "mob.chickenplop", 1.0F, (rand.nextFloat() - rand.nextFloat()) * 0.2F + 1.0F);
            dropItem(Item.egg.shiftedIndex, 1);
            timeUntilNextEgg = rand.nextInt(6000) + 6000;
        }
        */
    }

That's pretty much it. Well, you say, how do I see it fly? well let's make a little code to "poke" it into flying. Add this other method:

    public boolean interact(EntityPlayer entityplayer)
    {
    	//rightclick on this entity to make it jump up
    	this.motionY += 1;
        return true;
    }

Don't use a big number, this will have it jump several feet into the air, then flap it's wings back down. If you notice, they use multipliers (of less than 1) when adjusting the motionY variable. I once set it to 5, and wondered where the mob went. It was way up in the sky, and took a while to get back down.

If you want to make a block that throws you into the air, you can use this idea on a block. Of course, if you don't have the flying code, you're in for quite a fall. :smile.gif:

ok im making a ufo mod but need help on making is spawn and fly does this work for tht

To make a player API mod simply make a class that extends PlayerBase (much like extending BaseMod) and register it with PlayerAPI.RegisterPlayerBase(PlayerBaseExample.class); in your mod_ file constructor. An example PlayerBaseMoods is included in the download

To get a PlayerBase from the player you can use the method PlayerAPI.getPlayerBase(player, PlayerBaseExample.class);

If you require more hooks to make your mod work with player API, please PM me and it should be in the next release

Quote from Whiteheat

Well that was easier then expected, well if you don't feel like using a spawn block to spawn your mob you could always use an item like so :

public class ItemSpawnStaff extends Item
{

    public ItemSpawnStaff(int i)
    {
    	 super(i);
         maxStackSize = 1;
         setMaxDamage(64);
    }

    public boolean onItemUse(ItemStack itemstack, EntityPlayer entityplayer, World world, int i, int j, int k, int l)
    {
        if(!world.multiplayerWorld)
        {
        	EntityLiving entityliving = (EntityLiving)EntityList.createEntityInWorld("MyMob", entityplayer.worldObj);
            entityliving.setLocationAndAngles(i, j + 1, k, 0F, 0F);
            entityplayer.worldObj.entityJoinedWorld(entityliving);
        }
        return true;
    }
}

Use the same code for spawn block but in item form.

Help I tried to do the adding custom mobs and it recompile successfully but when they spawn, they are white in colour(the rarity is set to 200):


There is a picture in \mob\test. Please help! Reward will be a full of

Thanks!

Quote from InNeedOfHelp

I did put it in the minecraft.jar file, in fact, i used the startclient.bat previously. Now, i reobf and drag them into my minecraft.jar folder and checked that everything was there.
Result:

As you can see, the monster is obviously not spawning(might take a while to load) :sad.gif:


Still no texture :sad.gif:

If someone knows how to solve this, will be rewarded with 10 truckloads of
