...really? can you please give me information instead of just saying things that doesn't help me in the slightest.

I tried changing it, but it didn't work. public ItemStack onItemRightClick(ItemStack Stack, World World, EntityPlayer p) { Stack.getTagCompound().setInteger("float_time", 20); return Stack; } @SuppressWarnings("null") public void onUpdate(ItemStack Stack, World World, Entity p, int par4, boolean par5) { NBTTagCompound tag = Stack.getTagCompound(); if (tag == null && tag.getInteger("float_time") > 0) { tag.setInteger("float_time", tag.getInteger("float_time") - 1); // decrement float time p.motionY = 0.1F; } } }

Can you please tell me what certain parts of the code do? I think i would understand better if you actually explained what parts of the code are.

So, I did it, the floating works, but that's whenever i have it in my inventory, I float. How would i add the right click method into here: public void onUpdate(ItemStack is, World World, Entity Entity, int par, boolean par5, EntityPlayer p) { if (p.isAirBorne) { p.motionY = 0.1F; } } EDIT: Also, if you could, could you tell me how to drop the person at a specific point? Thanks.

can you give me some example / pseudo code? I don't understand how i set the upward motion.

This is the code i have so far: public ItemStack onItemRightClick(ItemStack Stack, World World, EntityPlayer p) { p.addVelocity(0, 10, 0); return Stack; I am trying to slow down when it launches the player so i can make it like the player is floating up. What would i add? I tried motionY, but that didn't slow it down. Can anyone help me with this?

nvm, got it working. Thanks for the help anyways.

I know how to do it for bukkit, but forge seems to be a little different and i just don't get it. Here is my code public void onBlockRightClick(PlayerInteractEvent e) { e.useBlock = Result.DENY; e.useItem = Result.DEFAULT; if (!(e.action.equals(e.action.RIGHT_CLICK_AIR))) return; e.entityPlayer.playSound("tm:ballooninflate", 1.0F, 1.0F); } }

So, i have a chestplate that i want when pressing a button, it will make the player float for a certain amt of seconds and then either drop or float to the ground. How would i do that?
