Hey, title pretty much says it all. I want to boost the player in the direction he is facing. I think I can do the boost part with addVelocity(), however I'm not sure what values to pass it so the player is boosted in the correct direction.

All help is appreciated.

Thanks!

Couldnt you get his current position and depending on what direction he is facing (ForgeDirection) you can set his x, y, or z depending on direction

 

Well, I don't want to set the x, y, and z, I want to actually quickly move him there(which can be done with addVelocity()). Also, I don't think ForgeDirection will work because what if the player is supposed to be boosted south-east? Obviously, to the game, they are facing one or the other and will choose one.

I guess that is true

I'd say look at the ender pearl entity code and see how it's thrown and do something similar.

Oh, that's a great idea! I looked into it and got it working! Thanks! If anyone wants to know how I did it, I took this code from EntityThrowable(the class ender pearl extends):

this.motionX = (double)(-MathHelper.sin(this.rotationYaw / 180.0F * (float)Math.PI) * MathHelper.cos(this.rotationPitch / 180.0F * (float)Math.PI) * f);
this.motionZ = (double)(MathHelper.cos(this.rotationYaw / 180.0F * (float)Math.PI) * MathHelper.cos(this.rotationPitch / 180.0F * (float)Math.PI) * f);
this.motionY = (double)(-MathHelper.sin((this.rotationPitch + this.func_70183_g()) / 180.0F * (float)Math.PI) * f);

If I read it correctly, this is how the game sets the motion of any entity that is being thrown. Then, all I had to do was change it up to work with my own code:

double motionX = (double)(-MathHelper.sin(entityPlayer.rotationYaw / 180.0F * (float)Math.PI) * MathHelper.cos(entityPlayer.rotationPitch / 180.0F * (float)Math.PI) * 1.5F);
double motionZ = (double)(MathHelper.cos(entityPlayer.rotationYaw / 180.0F * (float)Math.PI) * MathHelper.cos(entityPlayer.rotationPitch / 180.0F * (float)Math.PI) * 1.5F);
double motionY = (double)(-MathHelper.sin((entityPlayer.rotationPitch + 0F) / 180.0F * (float)Math.PI) * 1.5F);

entityPlayer.addVelocity(motionX, motionY, motionZ);

Using a multiplier of 0.4, like in the original ender pearl code, wasn't quite enough to get the boost I liked, so I chaned it to 1.5. Thanks!
