[1.7.10] entity.RotationPitch question

Frag · September 20, 2015

Hi guys,

I have created a fish that swim quite well under water, however, even if I was able to set the rotationyaw mostly correctly ... I am still looking for a rotation pitch formula. The pitch should be quite straightforward, since the fish is mobbing in a 3D environment under water, I woulk like its nose to point in the direction it is swimming.

Here is my rotationyaw code ...

float f = (float) (Math.atan2(aWaterMob.motionZ, aWaterMob.motionX) * 180.0D / Math.PI) - 90.0F;

float f1 = MathHelper.wrapAngleTo180_float(f - aWaterMob.rotationYaw);

aWaterMob.rotationYaw += f1;

What would be the rotation pitch code? I was not able to figure it out.

aWaterMob.rotationPitch +=?

Also ...if you have any hint so my mobs would not change the rotationyaw in one frame ... I would be very happy.

Thanks guy, this forum was really helpful to me in the last few days.

Use -math.cos(Math.toRadians(mob.rotationpitch)) should work.

Use -math.cos(Math.toRadians(mob.rotationpitch)) should work.

I noticed that even if I hardcode manually:

aWaterMob.rotationPitch=90F;

or

aWaterMob.rotationPitch=0F;

... the pitch of my mobs does not change. Would it be an issue with my model class? Is the rotationpitch is the correct value to set?! Does the pitch value is in synch between the server and the station like the rotationyaw?

Here is the model class.

No one know why RotationPitch does not change my pitch? My rotationyaw works ...go figure

ItsAMysteriousYT · September 21, 2015

Try this in your render method:

GL11.glPushMatrix();

GL11.glRotated(entity.rotationPitch,1,0,0);

//rest of the rendering stuff here

GL11.glPopMatrix();

Where did you hardcode the rotationPitch value?

Frag · September 22, 2015

Where did you hardcode the rotationPitch value?

In my movement class which is executed server side only. All my mobs motion are set server side. I noticed that the motion and yaw are kept in synch with the client.

I noticed that I can play with the pitch by using the client side GL11.glRotated method in the render class (which run client side). But I am curious to know why the pitch needs to be handled by GL11.glRotated...

So my question is back ... why rotationyaw is rendered correctly ...but not rotationpitch. I am probably missing something.

ItsAMysteriousYT · September 22, 2015

Cuz i think that changing the rotationPitchHead(if you have an EntityLivingBase) would rotate the model and not the rotationPitch. I don't know why Minecraft does this

Please post the image of the fish. I think you should apply rotation yourself.

Also please post code of your Render class.

    this.mouth.rotateAngleX = 0.17F*(MathHelper.cos(f2 * 0.06662F) ) + 0.8726646F;
    this.bodysection1.rotateAngleY = 0.2F *(MathHelper.cos(f2 * _fish.GetTailFlapSpeed() * 0.527F) );
    this.bodysection2.rotateAngleY = 0.2F *(MathHelper.cos(f2 *_fish.GetTailFlapSpeed() * 0.527F - (float)(Math.PI/6)) );
    this.bodysection3.rotateAngleY = 0.2F *(MathHelper.cos(f2 *  _fish.GetTailFlapSpeed() * 0.527F - (float)(Math.PI/3)) );
    this.bodysection4.rotateAngleY = 0.2F *(MathHelper.cos(f2 * _fish.GetTailFlapSpeed() * 0.527F - (float)(Math.PI/2)) );

    this.bodysection6.rotateAngleY = 0.2F *(MathHelper.cos(f2 * _fish.GetTailFlapSpeed() * 0.527F - (float)(5*Math.PI/6)) );

This might make your model like it is applying yaw.

Thanks Abastro, you were really helpful to me those days...

Just to make sure we are on the same page. The yaw is fine ... I have issue with the pitch. My fish will never point their nose up or down to swim thru their destination.

Also I think a photo of your model in minecraft would be a great help.

Now with the picture ...any ideas of what I am doing wrong? I am starting to think that the pitch is not in synch client/server side ...but that the rotation is.

Post your movement code I think you might have an issue somewhere in there with the pitch. They should be handled the same so theres probably an issue in the movement class. Show the classes in order of movement is set here-> movement is passed here -> fish is rendered here-> etc etc. will help in figuring this out.

Hi Thornack, thanks fir the help.

So my fish movement is called server side in this method.

//Math converted to use more accurate and readable Vec3's
public static void SwimTo(EntityFantasticFish aWaterMob, double xCoor, double yCoor, double zCoor, double speed) 
{
FantasticDebug.Output("Swim to new target");
if ((aWaterMob!=null) && (aWaterMob.isEntityAlive()))
{
	if (!aWaterMob.worldObj.isRemote)
	{
		double speedAdjustment = 0.1D;


			//Create vector
			Vec3 vec3 = Vec3.createVectorHelper(xCoor - aWaterMob.posX, yCoor - aWaterMob.posY, zCoor - aWaterMob.posZ).normalize();

			//Set motion and angles
			aWaterMob.motionX = (vec3.xCoord * speed)*speedAdjustment;
			aWaterMob.motionY = (vec3.yCoord * speed)*speedAdjustment;
			aWaterMob.motionZ = (vec3.zCoord * speed)*speedAdjustment;

			//*** OPTION 1
			float f = (float) (Math.atan2(aWaterMob.motionZ, aWaterMob.motionX) * 180.0D / Math.PI) - 90.0F;
			float f1 = MathHelper.wrapAngleTo180_float(f - aWaterMob.rotationYaw);
			aWaterMob.rotationYaw += f1;



			aWaterMob.rotationPitch = 0.5F; //I can set anything here, the pitch will never change	
		//}



	}
}
}

Notice the line aWaterMob.rotationPitch ... I can set any values in there ... pitch NEVER change. Do you know where that pitch should be passed as a parameter in SetRotationAngle?

Hi guys,

I am still hunting that pitch issue. Actually, reading a tutorial from Jabelar led me to this one.

http://greyminecraftcoder.blogspot.ca/2015/07/entity-rotations-and-animation.html?showComment=1444584624236#c7188593033068666922

In this tutorial, the author specifically talk about the DoRender and DoRenderEntity ... which seems that they do not get the pitch by parameters.

HEre are the signature of both methods ...so where is the pitch value client side!!??

RenderManager::

doRenderEntity(Entity entity,

double x, double y, double z,

float rotationYaw, float partialTicks,

boolean showOutline);

this then calls the Entity Renderer:

RendererLivingEntity::

doRender(Entity entity,

double x, double y, double z,

float rotationYaw, float partialTicks);
