Creating a formula to spawn an arrow based on the players rotation

[explosion33]

Im Making A dartGun for minecraft but it currently fires an arrow out of the head. Im trying to make it shoot out of the barrel of the gun but I cant figure out how to find what direction the player is facing and using that direction to create a formula for spawning it exact each time

inn 1.7.10 i think you might want to look at rotationPitch and rotationYaw

dude

the entity arrow alredy has code for thath.

 

        this.posX -= (double)(MathHelper.cos(this.rotationYaw / 180.0F * (float)Math.PI) * 0.16F);

        this.posY -= 0.10000000149011612D;

        this.posZ -= (double)(MathHelper.sin(this.rotationYaw / 180.0F * (float)Math.PI) * 0.16F);

 

this pieze of code causes the arrow to spaw at 0.16 mtrs to the rigth of the entity shooter
