Be more specific. Do you want everyone reading to spawn an entity in front of the player on item right click?

 

If you mean a projectile, say so. If you mean a <? extends EntityLivingBase> then say so.

    public static Vec3 getPointUsingAnglesRange(Vec3 start, float yaw, float pitch, float range){
        double coordX = start.xCoord + (double) (-MathHelper.sin(yaw / 180.0F * (float) Math.PI) * MathHelper.cos(pitch / 180.0F * (float) Math.PI) * range);
        double coordY = start.yCoord + (double) (-MathHelper.sin(pitch / 180.0F * (float) Math.PI) * range);
        double coordZ = start.zCoord + (double) (MathHelper.cos(yaw / 180.0F * (float) Math.PI) * MathHelper.cos(pitch / 180.0F * (float) Math.PI) * range);
        return Vec3.createVectorHelper(coordX, coordY, coordZ);
    }

I believe what they may be looking for is something that I was just talking about yesterday. You use and item to right click the ground and like magic a entity appears in front of ya. What I don't know is if it is suppose to be a custom entity or if you want a zombie, or if the entity is a creature, or something like a painting. I do know that VSWE has a video tutorial for that if you want a custom entity in this case its a spaceship. It's for 1.6 but the porting isn't hard. The one thing I got stumped on was MultiMote suggested instead of doing something like.

ship.posX = 0.5;
ship.posY = 1.5;
ship.posZ = 0.5;

 

do:

 

ship.setLocationAndAngles(x + 0.5, y + 1.5, z + 0.5, 0, 0);

 

Again though that's for a spaceship not a mob. Don't know what you are looking for when you say just entity.
