Is there a replacement for gluProject / gluUnProject in 1.15.2 mdk?

I recently made a post about achieving a isometric view, I was able to figure that out pretty easily googling around and figuring out how to make a basic coremod to modify the frustum method in ClippingHelperImpl to prevent chunks / entities fading out behind the player. I have ran into another problem of trying to get the player head to follow where the mouse is on the screen. I currently just use a empty Screen GUI (I don't know if this is the best way of accomplishing this vs ungrabbing the mouse) The things I need to find out how to accomplish is: Have the player face the mouse on screen The best way to have the mouse show on screen (Empty GUI vs ungrabbing the mouse) converting screen to world coordinates (click on block and it raytraces it, and implement the player moving to that block) This is my current prototype code for trying to get the player character to follow the mouse

So I am currently working on a Action RPG hack and slash mod for 1.15.2 and I have having trouble figuring out how to create an isometric view in 1.15.2. I have looked at other mods such as mineshot and shoulder surfing reloaded and I have figured out how to modify the position of the player camera using reflection (ActiveRenderInfo has some methods and fields with access modifiers protected and private. I have tried doing some openGL things but I couldn't figure that out. I also need to figure out how restrict the player from looking up and down. Code for my cameraSetup event handler

Im trying to make a scroll page so that only 6 rows of items show up, and I can't find a replacement for the system in 1.10+ found containerClass.getSlot(index).x/yPos.

Inventory was not being set to the container so whenever initgui was called it was null causing the crash

So I want to create scrollbar that is going to be apart of my custom storage device for my mod, which is going to sort and display items based of their NBT values so that it would be more storage efficient for the player to use. I have tried basing my code off the method that vanilla does for the creative inventory, and I am currently having a issue where when I change the size of the game window the game crashes with a null pointer exception.

I potentially fixed the error as I forgot to override markDirty(); in the tileentity class, need to work on getting the scrolling to work.

I have been working on getting a scroll bar to work for both items and a list of buttons which will be based off the items put into the container in which i'm using. Recently during testing I have been having a issue where markDirty(); is infinitely called causing a stackoverflow error whenever I click on a slot inside of the gui of the container I am using, and I would like to find out why and fix it so I can get the scrollbars working properly.

Hello, I have been having issues trying get my machine to face the player on placement like many other mods, I've tried overriding methods found in the vanilla chest class file however 3/4 of the methods are 'Deprecated', and I was wondering if there is a new method to do this in 1.12?

Sorry for late reply, I implemented this solution thanks for the help.

yes, I have but that is the issue for me it's not grabbing the NBT tag, but other options it does idk what is going on

@SubscribeEvent public void itemPickup(PlayerEvent.ItemPickupEvent event){ ItemStack stack = event.getStack(); if (stack.getItem().equals(ModItems.mobSoul)) { System.out.println("You picked up Mob Soul"); NBTTagCompound nbt = stack.getTagCompound(); if (nbt == null) { nbt = new NBTTagCompound(); System.out.println("NBT Created for Mob Soul"); } if (nbt.hasKey("potency")) { nbt.setInteger("potency", nbt.getInteger("potency")); } else { System.out.println("Random Value generated for Potency value"); nbt.setInteger("potency", (int) (Math.random() * 100) + 1); } System.out.println("Value written to NBT tag"); stack.setTagCompound(nbt); } } This is my Event code, so what I want to do is when I pick up my custom item from a mob drop, it will generate a random number to be put inside of a tooltip showing how much "potency" the item has. @SideOnly(Side.CLIENT) public void addInformation(ItemStack stack, @Nullable World worldIn, List<String> tooltip, ITooltipFlag flagIn) { if (stack.hasTagCompound() && stack.getTagCompound().hasKey("potency")) { NBTTagCompound nbt = stack.getTagCompound(); System.out.println(nbt); if (nbt != null && nbt.hasKey("potency")) { int pot = nbt.getInteger("potency"); tooltip.add("Potency: " + pot); } } else { tooltip.add("Potency: N/A"); } } this is my tooltip code, I've tried all of the troubleshooting that I know of, such as just using a onRightClick method using the same general code in the ItemPickupEvent, which worked fine however my issue strides from the event. I want to know if I am doing something generally wrong, as in 1.10 this same method worked for me previously.

Ok thanks for the help.

@SubscribeEvent public ItemStack soulDrop(LivingDropsEvent event) { DamageSource source = event.getSource(); Entity entity = source.getTrueSource(); EntityPlayer player = (EntityPlayer) entity; ItemStack soul = new ItemStack(ModItems.mobSouls); ItemStack hand = ItemStack.EMPTY; hand = player.getHeldItemMainhand(); NBTTagCompound nbt = soul.getTagCompound(); if (event.getEntity() instanceof EntityLiving && hand.getItem() == Items.IRON_HOE) { event.getDrops().add(new EntityItem(event.getEntity().getEntityWorld(), event.getEntity().posX, event.getEntity().posY, event.getEntity().posZ, new ItemStack(ModItems.mobSouls))); if(nbt == null){ nbt = new NBTTagCompound(); } if(nbt.hasKey("potency")){nbt.setInteger("potency", 0); }else{nbt.setInteger("potency", (int) Math.random()*100);} soul.setTagCompound(nbt); } return soul; } This is my code for item drop event, I have managed to do this prior in 1.10, however, I lost my prior source code.
