Posted September 19, 201411 yr I made an entity that the player is riding. when ridden both entities seem to jump up and down (not fluid) after a random amount of time. Probably some inconstancy between client and server or weird minecraft quirk. Hope someone can shed some light! http://s28.postimg.org/he70lcdwt/2014_09_19_11_21_04.png[/img] http://s27.postimg.org/kbay7orjn/2014_09_19_11_21_07.png[/img]
September 20, 201410 yr Hi Show some code? I've found position logging to be extremely useful for this type of problem eg System.out.println("position on side " + (this.worldObj.isRemote() ? "client" : "server") + " is [" + this.posX + ", " + this.posY + ", " + this.posZ + "]" ); (in one of the entity's tick update methods) That will show you if it really is a client/server mismatch, and might help you figure out where to look next. -TGG
September 21, 201410 yr Author Sorry, I should know better than to forget my code. Update: after adding a bit of code to the controller class (relating to bounding boxes and collision) the controller and ship block go up after a second (possibly just after I mount it, happens automatically) but not back (instead of the seat). According to: class com.deb.debmodularships.entities.EntityController's position on side server is [-2475.5, 56.0, 785.5] class com.deb.debmodularships.entities.EntityController's position on side client is [-2475.5, 56.0, 785.5] class com.deb.debmodularships.entities.EntityController's position on side server is [-2475.5, 56.0, 785.5] class com.deb.debmodularships.entities.EntityController's position on side client is [-2475.5, 57.0, 785.5] it does seem to be a client issue.

September 21, 201410 yr Author Update: When I sit in the seat it goes up a bit and the blocks randomly move up and down a tiny tiny bit.
September 21, 201410 yr sorry mate, nothing is coming to mind and I don't see anything obvious in that code (but then - I've never programmed riding entity stuff before either). What I would try next is to put a breakpoint on the client side posY (i.e. to break when it turns to say > 56.5) and see which method is writing the changed value in there. It will slow your code down a lot but with any luck it should show you exactly what is causing the problem. -TGG
September 22, 201410 yr Author I'll try it but could you elaborate on why and what to replace it with?
September 25, 201410 yr You didn't put super call in onUpdate(). Nor in writeToNBT(NBTTagCompound) and readFromNBT(NBTTagCompound).
September 27, 201410 yr Author I definitely did put the super calls in nbt stuff but after changing onUpdate, the same thing happens. New Controller file: package com.deb.debmodularships.entities; import net.minecraft.entity.Entity; import net.minecraft.nbt.NBTTagCompound; import net.minecraft.util.AxisAlignedBB; import net.minecraft.world.World; public class EntityController extends Entity { public EntityController(World par1World) { super(par1World); this.setSize(1, 1); } @Override protected void entityInit() { } @Override public void readFromNBT(NBTTagCompound nbt) { super.readFromNBT(nbt); } @Override public void writeToNBT(NBTTagCompound nbt) { super.writeToNBT(nbt); } public void onUpdate() { super.onUpdate(); System.out.println(this.boundingBox); } public boolean canBeCollidedWith() { return true; } public AxisAlignedBB getCollisionBox(Entity p_70114_1_) { return this.boundingBox; } public AxisAlignedBB getBoundingBox() { return this.boundingBox; } //IGNORE @Override protected void readEntityFromNBT(NBTTagCompound var1) { // TODO Auto-generated method stub } @Override protected void writeEntityToNBT(NBTTagCompound var1) { // TODO Auto-generated method stub } }
September 28, 201410 yr Author Looks like overriding OEU2 solved it, just wondering why... Thanking MultiMote now!
