Posted February 4, 201510 yr Hey guys, How can I prevent an item from falling in a liquid. This is the code I have now but the item just seems to jump around and stuff: package me.mrkirby153.KCNerfer.playTime; import net.minecraft.block.Block; import net.minecraft.block.BlockLiquid; import net.minecraft.entity.item.EntityItem; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.ItemStack; import net.minecraft.world.World; public class IndestructibleItem extends EntityItem { private final EntityPlayer owner; public IndestructibleItem(EntityPlayer owner, World world, double x, double y, double z, ItemStack itemStack) { super(world, x, y, z, itemStack); this.isImmuneToFire = true; this.owner = owner; } public boolean canPickup(EntityPlayer player) { return player.getCommandSenderName().equalsIgnoreCase(this.owner.getCommandSenderName()); } @Override public boolean isEntityInvulnerable() { return true; } @Override public boolean canRenderOnFire() { return false; } @Override public void onUpdate() { super.onUpdate(); Block currentBlock = worldObj.getBlock((int) Math.floor(posX), (int) Math.floor(posY), (int) Math.floor(posZ)); if (currentBlock == null) return; if (currentBlock instanceof BlockLiquid) { posY += 1; // System.out.println("in liquid"); } } } http://i.imgur.com/gWwyMMO.jpg[/img]

I'm back from being gone for... I think its been about a year. I'm pretty sure nobody remembers me, but hello anybody who does!

That didn't work. It still glitches around. http://i.imgur.com/gWwyMMO.jpg[/img]
February 5, 201510 yr Well if you actually go and look at the onUpdate function of EntityItem, you'd see why. this.motionY -= 0.03999999910593033D; this.moveEntity(this.motionX, this.motionY, this.motionZ); Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice. Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked. DO NOT PM ME WITH PROBLEMS. No help will be given.
February 6, 201510 yr Author Well if you actually go and look at the onUpdate function of EntityItem, you'd see why. this.motionY -= 0.03999999910593033D; this.moveEntity(this.motionX, this.motionY, this.motionZ); I see that the entity is still having its y axis position lowered. However, this doesn't really explain how to arrest the movement of an item. http://i.imgur.com/gWwyMMO.jpg[/img]
February 6, 201510 yr You know what the code does. You know that the code runs. What do you have to do such that when the code does what it does when it runs will it have the effect of stopping the motion?

February 6, 201510 yr Author You know what the code does. You know that the code runs. What do you have to do such that when the code does what it does when it runs will it have the effect of stopping the motion? Okay. I saw that the entity was being moved down by 0.03999999910593033D so I tried conteracting that by moving it up by 0.03999999910593033D (The same number), but the item still glitches around. Code now: @Override public void onUpdate() { super.onUpdate(); Block currentBlock = worldObj.getBlock((int) Math.floor(posX), (int) Math.floor(posY), (int) Math.floor(posZ)); /*if (currentBlock == null) return; if (currentBlock instanceof BlockLiquid) { this.motionY += 0.03999999910593033D; this.moveEntity(motionX, motionY, motionZ); } Block blockBelow = worldObj.getBlock((int) Math.floor(posX), (int) Math.floor(posY -1), (int) Math.floor(posZ)); if(blockBelow instanceof BlockLiquid){ this.motionY += 0.03999999910593033D; this.moveEntity(motionX, motionY, motionZ); }*/ this.motionY += 0.03999999910593033D; this.moveEntity(motionX, motionY, motionZ); } http://i.imgur.com/gWwyMMO.jpg[/img]
February 6, 201510 yr I included two lines, but you really only need to do one thing. (Note: I haven't done something like this myself) Try public void onUpdate() { Block blockBelow = worldObj.getBlock((int) Math.floor(posX), (int) Math.floor(posY -1), (int) Math.floor(posZ)); if(blockBelow instanceof BlockLiquid){ this.motionY = 0.03999999910593033D; } super.onUpdate(); } Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.

Does this have to deal with client/server syncing? http://i.imgur.com/gWwyMMO.jpg[/img]
February 7, 201510 yr Possible. As I said, I haven't really looked into it, but you might be best off completely overriding onUpdate (copy all of the code from super and then edit as needed).

February 7, 201510 yr You would have to give correct acceleration for that, depend on the height from the liquid block. giving same acceleration when it is over BlockLiquid would just make it glitch around, since it would not be 'smooth' I.
